What is the cause of the hot and cold switch socket? Trading treasure teaches you to distinguish
1. The quality of the socket is poor
First of all, we should check whether the plug is not a poor quality product. The clamping force of the copper in the defective socket is not enough, resulting in poor contact between the socket and the plug. When the appliance is used for a long time, the socket and the plug will be hot. Therefore, you must not buy cheap brand-name electrical products, you should buy a large brand outlet with quality assurance.
2. The socket capacity is too small
Secondly, because many friends bought a socket for general electrical power, but let it work overloaded, using high-power electrical products, resulting in a "small horse-drawn cart", which will lead to socket heating, shortening the service life, Damage to the appliance or even cause a fire. High-power appliances, such as air conditioners, induction cookers, microwave ovens, etc., generally require the selection of a socket with a rated current of 16A, while color TVs, refrigerators, washing machines, etc., select sockets with a rated current of 10A. Solution: Powerful appliances are not allowed to be used simultaneously on one outlet. Regular socket products are marked with rated voltage and current and should be carefully checked when purchased.
3. The plug is dirty
The plug is oxidized or oily, causing the contact resistance between the plug and the socket to increase, and the load power is large, causing the plug to heat up. If not treated in time, a vicious circle will be formed, which may cause a fire for a long time. Solution: Always wipe the electrical plug to prevent dust and copper from appearing on the plugs; apply sandpaper to the heavily oxidized plug, or replace the plug with a new one.
4. Loose wiring of socket and plug
The wiring of the socket and the plug is not strong, and the contact resistance is increased, which is also likely to cause heat. Solution: Secure the wiring.
5. Socket overtime work
The socket has a service life. At present, the households in rural households and urban houses in China have a considerable number of sockets that have been used for too long and exceed their normal service life. After the socket is over the service life, the copper pieces that are internally plugged are aged, and the clamping force is lowered, resulting in poor contact with the plug and easy heat generation. Solution: Consumers should have the concept of “outlet life†to allow old outlets to “retire†on time.
6. Simultaneous access to a variety of high-power appliances on the socket
Rural households and urban old house tenants, due to the unreasonable layout of the sockets, the number is also seriously insufficient, leading many families to connect a variety of electrical appliances to the same multi-purpose socket. Since the multi-purpose socket and the power cable have rated capacity, a variety of household appliances, especially high-power appliances, are simultaneously turned on and used on the same multi-purpose socket, which is bound to cause too much current, causing the multi-purpose socket and the plug to overheat. Solution: use fixed-position household appliances and high-powered electrical appliances (such as TV sets, refrigerators, microwave ovens, induction cookers, computers, audio, etc.), should be separately connected to the fixed socket, and the power cord of the high-power electrical fixed socket should also be It can be directly taken out from the household distribution box; for some electric appliances that are frequently moved, multi-purpose sockets can be used, but caution should be used. Do not open multiple electrical appliances at the same time to ensure safe use.
7. Use ordinary socket in humid environment
Some families install ordinary sockets in kitchens, bathrooms and other places. Due to the high humidity of the air and the presence of harmful gases in these occasions, the copper sheets in the socket are easily oxidized and rusted, resulting in an increase in contact resistance, causing overheating of the socket and the plug. Solution: Install a sealed socket in a wet location.
Recommendation : After the power plug of the socket and household appliance is hot, stop using it immediately, check the cause of the hot. If it is a product quality problem, replace the socket or plug. If the power of the appliance is too large, suspend the use of the appliance and carry out targeted Repair or replace.
