Children are born with love and lively, so children's safety hazards have become more numerous, especially children's electric shock events often occur, so someone invented a child-resistant electric shock device, but this security is still controversial. The following small series for everyone to introduce how to choose child safety socket and child safety socket safety. How to choose child safety socket 1, if there is a child at home, you can choose a waterproof socket, because the child's curiosity is stronger, like to plug stuff or pour water into the hole in the socket, and this child safety socket can effectively prevent the leakage of water after the end of the harm . 2. Children's safety sockets can prevent the exposed copper strips from being exposed, which can effectively prevent electrical shocks due to finger or metal objects touching the sockets. In addition, such a design can prevent a child from inadvertently touching a power source or a metal object falling into a socket and causing danger. 3, can see the wire, for the 10A socket extension cord core not less than 1 square millimeter, so consumers can see when the purchase of the extension cord core specifications are described. 4, see whether the child safety socket 3c certification, the current socket must have a national mandatory product certification. So consumers can see if there is this sign on the packaging. Is child safety socket safe? The child safety socket at the beginning was only equipped with protective measures outside the socket, but this measure was too simple and could not effectively prevent electric shock. With the development of science and technology, a child safety socket with a built-in safety protection door has been devised. Such a socket cannot be inserted with children's strength. In addition, there is a child safety socket with double protection doors as protection, with single plug lock with electrode jack, and three-level door independent protection technology, in the process of electricity, children will not encounter any single pole will have There is an electric shock phenomenon, and there is also an independent lock switch that does not energize when not in use and can provide a safer protection for the child.

Plugs and sockets, converter quality issues are an important cause of electrical fires. Therefore, when purchasing plugs, sockets, converters, and switches, consumers should focus on product safety. The main performance indicators that affect its safety are: Signs, ratings, dimensions, protection against electric shock, structure, power cord, mechanical strength, heat and flame resistance. Understand the safety performance of the plug and socket, and at the time of purchase and use, grasp the following points to ensure the safety of your family and property: A selection, choose a regular shopping mall, supermarket or specialty store, select brand products; according to the power of the use of electrical options to select the appropriate (matching) products, such as: air conditioners, high-power showers and other products should use 16A plug socket, other low power 10A plug and socket can be used for home appliances. Second, look at the product signs are complete, see if there is no CCC certification mark. Three investigations, inspection of inspection certificates issued by the certificate and statutory authorities. If converter products are not included in the compulsory certification, the inspection report issued by the statutory inspection agency should be checked when purchasing. Four trials, a simple plug-in experiment, the plug should be in good contact after insertion into the socket, there is no loose feeling, and can be pulled out without much effort. Pay attention to the fact that do not use the plug that can be swiveled with the plug or change the shape of the plug; do not use two power devices at the same time on one socket; stop when the plug or the power cord is overheated or sparks Use and replace.

In general, Europe is the preferred tourist country for everyone. So when we go abroad, we need to prepare something. Everyone knows that the commonly-made plug converters cannot be used normally in foreign countries. Therefore, we must have prepared the European standard plug converter, so that we can make it more convenient after we go abroad. Here we come to understand how to choose the European standard socket , and how the conversion plugs of the European standard and German standard are different. European standard socket how to buy First, in the purchase of European standard outlets, we choose the best business is the regular, and relatively high reputation of some stores, etc., and select the product can be selected according to the power of the use of the appropriate brand of electrical appliances. Such as: air conditioners, high-power showers and other products should use 16A plugs and sockets, other low-power appliances use 10A plugs and sockets can be, to see whether the product logo is complete, see if there is no CCC certification mark. Second, the selected European standard socket products, we must also check the product's certificate, as well as some relevant departments of the inspection report. If converter products are not included in the compulsory certification, the inspection report issued by the statutory inspection agency should be checked at the time of purchase. For a simple plug-in experiment, the plug should be in good contact after it is plugged into the socket, there is no loose feeling, and it can be pulled out with less force. Third, in the selection of plugs for those plug rotation, as well as artificially modified plugs, we all better not to buy. Also, do not use two power-intensive appliances at the same time on one outlet. If you find that the temperature of the plug, socket, or power cord is too high or there is a fire, you should stop using it and replace it. What is the difference between the European standard and the German standard adapter? First, the shape of the European standard plug is round, while the German standard is similar in some places, but the German standard has a larger diameter than the European standard. In addition, the German standard also has a built-in ground wire. European standard plugs are used in Germany, France, the Netherlands, Denmark, Finland, Norway, Poland, Portugal, Austria, Belgium, Hungary, Spain, Sweden and other EU countries as well as South Korea, Russia and other countries. They are characterized by two round heads. Second, the role of the conversion plug is the shape of the socket, because the shape of the foreign socket and our domestic plug products are not matched, your electrical appliances can be plugged in after conversion. But need to pay attention to the conversion plug does not have a transformer function, that is if you insert a 220 volt voltage socket, the output is still 220V, insert 110V foreign socket, the output is still 110V. But at present, most portable devices can carry a wide voltage, 100-240V is applicable, and most of them do not use transformers, such as mobile phones, cameras, laptops and other chargers. Specific use of voltage, electrical appliances are labeled, sum up, wide voltage electrical conversion plug can be used directly in the global scope. The above about the European standard socket how to buy, as well as the European standard and German standard conversion plug which different content is introduced here, I hope these will help everyone.

Judging from the current market conditions, the types of outlets are very large, coupled with the diversification of user needs, there has been a new type of timer socket, practicality is very strong, for example, some appliances require a certain charging time, but many people Often forget the charging time, a long period of overcharge will cause damage to the appliance, so that with this type of product, then what is the use of the timer socket ? Let's take a look What are the timer socket uses? 1, rice cooker timing The rice cookers in many people do not have reservation options, but they also hope that when they get up or go home from work, they can immediately eat hot meals. At this time, the timer socket will play a huge role. Connect the socket to the rice cooker and set it up. The start time and the off time of the power connection are good, so that you can eat fragrant meals for a fixed period of time. 2, drinking fountain timing In general, drinking fountains need electricity for a long period of time. If they are at home on the weekends, but they sleep on weekdays or at night, electricity will be wasted on such devices, and electricity will not be available when they are turned on or they wake up. At this time, the timing socket can be selected to directly skip the time when the water dispenser does not need to be energized and set the time required to be energized. 3, water heater timing Since the home is not like a hotel, the water heater needs to be energized for 24 hours. At home, it only needs hot water in the morning and evening. Therefore, the timer socket can be used to ensure that there is hot water when the home has hot water. Effectively save electricity costs and reduce the loss of water heaters. Timer socket usage notes 1, try to set the time as accurate In order to save electricity, when setting up, the time should be set as accurate as possible, for example, a 2~3L rice cooker, the porridge time is about one and a half hours, if the family is generally 6:00 to get up, then it should be The time is set at 4:30 in the morning, so that the porridge is just cooked at 6 o'clock and can be eaten directly after the family wash. 2, try not to insert multiple appliances at the same time In the same socket, you should prevent the use of multiple devices for timing, although this can save the socket, but it can easily lead to excessive starting current, causing the socket to burn out or catch fire. The drawbacks are obvious. In addition, after setting the time, do not Forgot to press the key to the outlet, otherwise the socket or the appliance did not move until the time of the appointment.

Smart grid technology will greatly increase the reliability of power systems, reduce energy losses, delay and reduce the need for new energy sources and loads. This technology is a major change in the power industry and will also promote social, economic and environmental development. It can be seen that the development of smart grid technology in the next few years is also reasonable. This brings opportunities and challenges for distribution network system upgrades, substation automation and power transmission, smart grid networks and smart meters. Today, the use of artificial intelligence in modern instrumentation makes it possible not only to solve the type of problems that conventional methods cannot solve, but also to solve problems that cannot be solved by traditional methods. The integration of artificial intelligence and the development of modern instruments and meters, and the creation of smart instruments and meters have important significance for the construction of smart grids. Judging from the situation in the past three years, the sales volume of the smart power meter industry in China was less than 2.5 million units in 2010, increasing to about 3.3 million units in 2011. This figure exceeded 4 million units last year. In the past three years, the average annual compound growth rate reached 29.62%. According to the development plan of the State Grid Corporation of China, the development of the smart grid in China will go through three stages of development, namely, technology research and development and standard development, comprehensive construction and improvement. At present, the development of China's smart grid has entered a phase of comprehensive construction and has generated a huge market demand for smart power meters. After 2016, China's smart grid will enter the stage of perfect improvement, and it will upgrade some of the old and old meters. The industry expects the growth of the smart power meter market will exceed 40% after 2016. It is believed that many people have forgotten to close their sockets when using electrical appliances. The consequences of forgetting are often the damage to the items or some safety incidents. Now, in order to prevent the occurrence of these electricity accidents, there is more material on the market called timer switch sockets. Its use reduces our safety risks and solves our problems.

The price of the five-hole socket panel is generally around 20 yuan. If it is generally more than 10 yuan with usb, don't be greedy for cheap, otherwise there will be potential security risks. 6. When buying USB socket panel at the recommended price, it is best to choose a brand socket, the quality can be more guaranteed. Types of usb socket 1. There is no button switch for straight-through USB sockets, and its cost is relatively low. The USB of this type of socket is directly in contact with household voltage and keeps running at the same time, so the service life is relatively short, and there are also certain safety risks. 2. The USB socket with a button is relatively safe. This type of socket with a button can only be powered by pressing the button, and it will not be in constant contact with the household voltage, so it is safer. 3. USB socket with automatic power off, it has a built-in switch, the switch is on when it is inserted, and it is off when it is pulled out. Many sockets with buttons are not designed to be user-friendly, and many people will forget to turn off the button, so they have designed sockets that automatically power off.

Children are born with love and lively, so children's safety hazards have become more numerous, especially children's electric shock events often occur, so someone invented a child-resistant electric shock device, but this security is still controversial. The following small series for everyone to introduce how to choose child safety socket and child safety socket safety. How to choose child safety socket 1, if there is a child at home, you can choose a waterproof socket, because the child's curiosity is stronger, like to plug stuff or pour water into the hole in the socket, and this child safety socket can effectively prevent the leakage of water after the end of the harm . 2. Children's safety sockets can prevent the exposed copper strips from being exposed, which can effectively prevent electrical shocks due to finger or metal objects touching the sockets. In addition, such a design can prevent a child from inadvertently touching a power source or a metal object falling into a socket and causing danger. 3, can see the wire, for the 10A socket extension cord core not less than 1 square millimeter, so consumers can see when the purchase of the extension cord core specifications are described. 4, see whether the child safety socket 3c certification, the current socket must have a national mandatory product certification. So consumers can see if there is this sign on the packaging. Is child safety socket safe? The child safety socket at the beginning was only equipped with protective measures outside the socket, but this measure was too simple and could not effectively prevent electric shock. With the development of science and technology, a child safety socket with a built-in safety protection door has been devised. Such a socket cannot be inserted with children's strength. In addition, there is a child safety socket with double protection doors as protection, with single plug lock with electrode jack, and three-level door independent protection technology, in the process of electricity, children will not encounter any single pole will have There is an electric shock phenomenon, and there is also an independent lock switch that does not energize when not in use and can provide a safer protection for the child.

In fiber optic systems, measuring optical power is the most basic, much like a multimeter in electronics. In fiber optic measurement, the optical power meter is a heavy duty common meter. By measuring the absolute power of the transmitter or optical network, an optical power meter can evaluate the performance of the optical equipment . Using an optical power meter in combination with a stable source, it is possible to measure connection loss, verify continuity, and help evaluate fiber link transmission quality. What is an optical power meter? An optical power meter is used to measure absolute optical power or relative loss of optical power through a length of optical fiber. When selecting an optical power meter, the most important technical indicator is the wavelength and range of the test. The unit of optical power is dbm. In the specification of the optical transceiver or switch, there is its illuminating and receiving optical power. Generally, the illuminating light is less than 0 dbm. The minimum optical power that the receiving end can receive is called sensitivity, and the maximum optical power that can be received is subtracted. The unit of sensitivity value is db (dbm-dbm=db), called dynamic range, and the illuminating power minus the receiving sensitivity is the allowable fiber attenuation value. The actual illuminating power at the time of testing minus the value of the actually received optical power. Is the fiber loss (db). The best value of the optical power received at the receiving end is the maximum optical power that can be received - (dynamic range / 2), but generally not so good. Due to the dynamics of each optical transceiver and optical module The range is different, so the specific amount of fiber can allow the attenuation depends on the actual situation. Generally, the allowable attenuation is about 15-30db. Some optical power meter product specifications only have two parameters of luminous power and transmission distance. Sometimes, the transmission distance calculated by the attenuation per kilometer of fiber is mostly 0.5db/km. The minimum transmission distance is divided by 0.5. The maximum optical power that can be received. If the received optical power is higher than this value, the optical transceiver may be burned out. The maximum transmission distance divided by 0.5 is the sensitivity. If the received optical power is lower than this value, the link may be Will not work. There are two ways to connect a fiber: One is a fixed connection, one is an active connection, and the fixed connection is a fusion connection. The special connection is through discharge, and the optical fiber is melted to connect the two optical fibers together. The advantage is that the attenuation is small, and the disadvantage is that the operation is complicated and the flexibility is poor. Through the connector, usually the pigtail is connected to the ODF. The advantage is that * for simple flexibility, the disadvantage is that the attenuation is large. Generally speaking, the attenuation of an active connection is equivalent to one kilometer of fiber. The attenuation of the fiber can be estimated by including fixed and active connections, and the attenuation of the fiber per kilometer is 0.5 db. If the active connection is relatively small, the value can be 0.4 db. Simple fiber does not include active connection, can be reduced to 0.3db, the theoretical value of pure fiber is 0.2db / km; for insurance, in most cases, 0.5 is better.

In general, Europe is the preferred tourist country for everyone. So when we go abroad, we need to prepare something. Everyone knows that the commonly-made plug converters cannot be used normally in foreign countries. Therefore, we must have prepared the European standard plug converter, so that we can make it more convenient after we go abroad. Here we come to understand how to choose the European standard socket , and how the conversion plugs of the European standard and German standard are different. European standard socket how to buy First, in the purchase of European standard outlets, we choose the best business is the regular, and relatively high reputation of some stores, etc., and select the product can be selected according to the power of the use of the appropriate brand of electrical appliances. Such as: air conditioners, high-power showers and other products should use 16A plugs and sockets, other low-power appliances use 10A plugs and sockets can be, to see whether the product logo is complete, see if there is no CCC certification mark. Second, the selected European standard socket products, we must also check the product's certificate, as well as some relevant departments of the inspection report. If converter products are not included in the compulsory certification, the inspection report issued by the statutory inspection agency should be checked at the time of purchase. For a simple plug-in experiment, the plug should be in good contact after it is plugged into the socket, there is no loose feeling, and it can be pulled out with less force. Third, in the selection of plugs for those plug rotation, as well as artificially modified plugs, we all better not to buy. Also, do not use two power-intensive appliances at the same time on one outlet. If you find that the temperature of the plug, socket, or power cord is too high or there is a fire, you should stop using it and replace it. What is the difference between the European standard and the German standard adapter? First, the shape of the European standard plug is round, while the German standard is similar in some places, but the German standard has a larger diameter than the European standard. In addition, the German standard also has a built-in ground wire. European standard plugs are used in Germany, France, the Netherlands, Denmark, Finland, Norway, Poland, Portugal, Austria, Belgium, Hungary, Spain, Sweden and other EU countries as well as South Korea, Russia and other countries. They are characterized by two round heads. Second, the role of the conversion plug is the shape of the socket, because the shape of the foreign socket and our domestic plug products are not matched, your electrical appliances can be plugged in after conversion. But need to pay attention to the conversion plug does not have a transformer function, that is if you insert a 220 volt voltage socket, the output is still 220V, insert 110V foreign socket, the output is still 110V. But at present, most portable devices can carry a wide voltage, 100-240V is applicable, and most of them do not use transformers, such as mobile phones, cameras, laptops and other chargers. Specific use of voltage, electrical appliances are labeled, sum up, wide voltage electrical conversion plug can be used directly in the global scope. The above about the European standard socket how to buy, as well as the European standard and German standard conversion plug which different content is introduced here, I hope these will help everyone.
