1. The socket quality is low quality
First of all, we should check whether the socket is a miscellaneous and inferior product, the copper clamping force in the defective socket is not good, resulting in poor contact between the socket and the plug, and the socket and plug will heat up after a long time of electrical use. Therefore, you must not buy cheap miscellaneous electrical products, and you should buy big brand sockets with quality assurance.
2. The socket capacity is too small
Secondly, because many friends bought a socket for the use of general electrical power, but let it overload the operation, and use high-power electrical products, constituting a "small horse-drawn cart", which will cause the socket to heat up, shorten the service life, damage the electrical appliances and even cause fire. High-power electrical appliances, such as air conditioners, induction cookers, microwave ovens, etc., generally require the selection of sockets with an additional current of 16A, while color TVs, refrigerators, washing machines, etc., choose sockets with an additional current of 10A. Solution: Powerful appliances are not allowed to be used together in one socket. Regular socket products are marked with additional voltage and current, which should be carefully confirmed when purchasing.
3. The plug is dirty
The plug is oxidized or oily, which increases the touch resistance of the plug and the socket, and the load power is large, resulting in the plug being hot, if not treated in time, it will constitute a vicious circle, and it is easy to cause fire after a long time. Solution: Wipe the electrical plug frequently to avoid dust accumulation and patina at the north and south poles of the plug; Sandpaper the heavily oxidized plug or replace it with a new one.
4. The wiring of the socket and plug is loose
The wiring of the socket and plug is not strong, and the touch resistance increases, which also simply leads to heating. Solution: Assemble the wiring firmly.
5. Socket overdue operation
At present, a considerable part of the socket in China's rural families and urban households living in old houses has a long service life, beyond its normal service life. After the socket exceeds the service life, the copper parts connected internally are aged, and the clamping force is reduced, resulting in poor contact with the plug and simple heating. Solution: Customers should have the concept of "socket service life", so that the old socket can be "retired" on time.
6. Connect a variety of high-power electrical appliances together on the socket
Rural families and residents of old houses in towns and cities have a serious shortage of sockets due to the unreasonable layout of sockets, resulting in many families connecting multiple electrical appliances to the same multi-purpose socket. Because the multi-purpose socket and power cable have additional capacity, a variety of household appliances, especially high-power appliances, are used together in the same multi-purpose socket, which is bound to constitute too much current, causing the multi-purpose socket and plug to overheat. Solution: The use of fixed household appliances and high-power electrical appliances (such as televisions, refrigerators, microwave ovens, induction cookers, computers, stereos, etc.) should be connected to the fixed socket alone, and the power cord connected to the fixed socket of high-power electrical appliances should also be directly drawn out of the household distribution box; For some electrical appliances that are often moved, multi-purpose sockets can be used, but they need to be used cautiously, and do not open multiple electrical appliances together to ensure the safety of use.
7. Use general sockets in humid environments
Some households install general sockets in kitchens, bathrooms, etc. Because of the high humidity of the air and the presence of harmful gases in these occasions, the copper sheet in the socket is simply oxidized and corroded, which constitutes an increase in touch resistance and causes the socket and plug to overheat. Solution: Install a sealed socket in a wet area.
Suggestion: After the plug of the socket and household appliance power supply is hot, stop using it immediately, check the cause of the heat, replace the socket or plug if it is a product quality problem, and suspend the use of the appliance if the electrical appliance is too powerful, and carry out targeted repair or replacement.
