1. The quality of the socket is low
First of all, we should check whether the socket is a miscellaneous defective product, the copper clamping force in the defective socket is not enough, resulting in a poor connection 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, resulting in a "small horse-drawn cart", which will cause the socket to heat up and shorten the service life, damage the electricity and even cause fire. High-power electrical appliances, such as air conditioners, induction cookers, microwave ovens, etc., are generally required to select a socket with a rated current of 16A, while color TVs, refrigerators, washing machines, etc. Regular socket products are marked with rated voltage and current, and should be carefully confirmed when purchasing
3. The plug is dirty
The plug is oxidized or oily, resulting in an increase in the contact resistance between the plug and the socket, coupled with the large load power, 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: Scrub the electrical plug frequently, avoid dust accumulation and patina on both poles of the plug, and apply sandpaper sanding to the plug with severe oxidation, or replace the plug 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
The socket has a service life, and at present, the households of rural families and old houses in cities and towns in China have an appropriate part of the suitable seat for a long service life, exceeding its normal service life. After the socket exceeds the use limit, the copper parts of the internal plug are aged, and the clamping force is reduced, resulting in poor contact with the plug and simple heating. Solution: Consumers 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 severe 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 the source connection cable have a fixed capacity, a variety of household appliances, especially high-power electrical appliances, are turned on and used together on the same multi-purpose socket, which will inevitably cause a large current and cause overheating of the multi-purpose socket and plug. Solution: The use of fixed location of household appliances and high-power electrical appliances (such as televisions, electric ice, microwave ovens, induction cookers, computers, audio, 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 led out of the household distribution box; Regarding some frequently mobile electrical appliances, multi-purpose sockets can be used, but they need to be used cautiously, do not turn on multiple electrical appliances at the same time, and ensure the safety of use.
7. Use general sockets in humid environments
Some families install general sockets in kitchens, bathrooms and other occasions, because the air humidity in these occasions is high, and there are harmful gases, the copper sheet in the socket is simply oxidized and corroded, resulting in the increase of touch electric yang, causing overheating of sockets and plugs. Solution: Install a sealed socket in a wet area.
Suggestion: After the plug of the socket and household appliances 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 electrical appliances for targeted maintenance or replacement if the power of the appliance is too high.
