Reasons for electric sparks from plugging in:
1, the amount of current is too large. Plug generated is not a spark, but an arc, belonging to the phenomenon of gas discharge, when the amount of current is too large, such as rated current overload, will be through the air and other media produced by the instantaneous spark.
2, the plug and socket connection is too tight. If the plug and socket is too tight, pulling out will issue a violent friction, which will lead to fire center splash.
3, the resistance is 0. When the resistance between the current and the current is 0, it will also spark.
4, the power of the appliance is large, resulting in the plug just touching the power supply, there will be a large current instantly through the plug's copper, resulting in sparks at the plug. This situation is a normal phenomenon, do not worry.
5, the wiring of the socket is not solid, resulting in poor contact and the formation of sparks.
6, reed and plug contact is poor. When the socket reed and the plug has a poor contact will also appear sparks.
7, poor socket contact. Poor contact of the socket, when inserted into the current, it will fire, this case is a fault.
Methods to prevent plug sparking: Some multi-function sockets will have too much contact between the plug and the interior, resulting in low resistance, arcing phenomenon. If the days are long, it is recommended to change a counterpart of the socket, especially the interface model to correspond. Let's say the triangle socket is relatively small, if you use ordinary electrical plug access into it, resulting in pulling out inconvenient, but also easy to bring up sparks. Do not just change the plug structure, some families do not have a triangular plug, hard ground wire into the two holes, not only trigger the fire, but also cause a short circuit, and even cause a fire.
