Question: Why are there sparks when I pull out the aviation plug?
Answer: I believe many people have encountered such a situation. Why does an electric spark occur? This is because the circuit is connected before the aviation plug is pulled out, and there is a very strong current on the electrical appliance and wire. This current will flow through the wire. A very strong magnetic field is established around it, so when we pull out the aviation plug, the current will change from strong to zero in a short period of time. At this time, the magnetic field will also change greatly. Due to the high voltage induced in the wire, the wire The induced high voltage is in the same direction as the original voltage, thus causing the total voltage to increase instantaneously, and sparks will be generated between the aviation plug and socket.
Since the temperature of electric sparks is very high, once there are electric sparks when pulling out the aviation plug, it is easier to cause damage to the tips of the plug and socket, affecting the service life of the plug and socket.
How to reduce the negative impact of electric sparks on aviation plugs? Generally speaking, electric switches are designed with springs, and the springs will automatically pull the contact points farther away, which can effectively shorten the existence time of electric sparks and reduce the number of aviation plugs. Damage to the plug. When we suspect that there are sparks when the aviation plug is pulled out, do not switch the switch to avoid accidents caused by sparks.
