Poor contact between the plug and the socket
When the plug is not in direct contact with the copper of the socket, but the gap between them is very small, the electrical energy passes through the air and transmits electricity, so this sound is made. Take it apart and look. It is sure that the copper contact part has been oxidized and blackened, and its elasticity has also become poor. It is best to replace it quickly with a new one. . Be careful not to buy cheap ones when purchasing. It is better to buy brands like TCL and Panasonic, especially if the electrical power is relatively high. There is poor contact between the plug and the wall outlet. When an electrical appliance is turned on, the copper plate between the plug and the wall outlet generates heat due to contact resistance. The copper plate heats and oxidizes to further increase contact. This cycle gets worse, generating small sparks and grinses.
Is it dangerous to make a crackling noise from a wall outlet?
Sparks from multi-use outlets. are the cause of poor socket contact. As long as there is no direct contact with conductive parts, it generally won't harm anyone.
Solution:
Check carefully for patina or other dirt on the plug and socket. If so, polish the plug with sandpaper, then insert it into the socket and feel it. with your hands. If so, use pliers to tighten the plug. If it still doesn't work, the wiring in the outlet itself is loose. Turn off the power switch of the outlet, then disassemble the outlet. use a small screwdriver to tighten the socket clamp screw again, then install it. If you have no knowledge of electrical appliances, it is better to ask a professional electrician to solve the problem.problem.
Sockets are often used in everyday life. If you don't pay attention, some problems will inevitably arise. So, are crackling wall outlets dangerous? The editor will present it to you immediately.
1. Is it dangerous if the wall outlet rings?
Strange noises from outlets can be dangerous. Generally, there is an arcing phenomenon in the gap caused by poor contact inside the socket. Although the current household voltage is relatively low, the generated arc is small and cannot normally reach zero fire, resulting in a short circuit. However, the arc is likely to cause poor contact in the discharge part, causing the temperature to rise, causing the temperature to rise. taken to burn or catch fire. If the discharge is large, it may cause a short circuit or overload.
2. Other Common Socket Faults
1. Socket lighting
The quality of the socket itself is not up to par. Some friends are greedy for cheap. and purchase substandard sockets, resulting in sockets. The metal materials used are of inferior quality. Over time, the pins will change color, the tightness will not be sufficient, and sparks will easily occur during the plugging and unplugging process. In this case, it is recommended to replace the high quality plug with a standard quality plug.
2. The inside of the socket is dirty.
This situation is more likely to occur with exterior outlets or kitchen outlets. Often, due to environmental reasons, dirt tends to accumulate inside the socket, leading to the accumulation of oil stains, dust, etc. On the copper foil, it affects the contact withthe pins, causing jamming and sparking. Solution: Add a dustproof and waterproof cover to the outlet to reduce dirt inside the outlet.
3. Virtual connection in the socket.
Generally, virtual connections are not serious. During the plugging and unplugging process, there may be jolts or pieces of copper in the outlet, causing shifting. in some area, virtual connections appear, leading to short-term discharges. Solution: In this case, the wiring part must be fixed to ensure that it does not shake.
