Is the socket with leakage protection useful?

Nowadays, with the wide application of electrical appliances, the use frequency of sockets is getting higher and higher. It can be concluded that our daily use of ionization cannot open sockets. Sockets bring us a lot of convenience in using electricity, but there are also some security risks. If we use it improperly, the socket will leak easily. So what is a socket with leakage protection? Let's get to know each other with Bian Xiao.

1. Is the socket with leakage protection useful?

1, leakage protection socket can effectively prevent human body from getting an electric shock. Once the household appliances have a leakage accident or the equipment shell is charged, the power supply can be effectively cut off to ensure the safety of users.

2. Leakage protection socket is a kind of relay protection device specially used to detect whether the line leaks electricity. Under normal circumstances, the current flows from the live wire to the neutral wire, and the ground wire has no current, so the current of the live wire and the neutral wire is equal. The magnetic fields generated by these two equal currents cancel each other on the zero-sequence transformer inside the leakage protector, so there is no induced voltage in the secondary of the transformer. When the electrical appliance leaks, part of the current flows away through the ground wire, which causes the live wire current to be greater than the neutral wire current, and causes the secondary coil of the zero-sequence transformer to generate induced voltage. After this voltage signal is amplified by the amplifier circuit, the power supply is immediately cut off (tripped) to achieve the effect of preventing electric shock.

Second, which is the leakage protection socket?
