Single magnet type electric leakage protection socket

Abstract

The invention relates to a single magnet type electric leakage protection socket, which adopts a single magnet type electromagnetic tripping device and a standard auxiliary circuit adaptive with the device. When the socket or a load end of the socket has faults such as electric leakage, or zero line disconnection or neutral line disconnection, the tripping device can automatically trip and cuts off a power supply under control of the auxiliary circuit, the tripping speed can be less than 25ms, and the threshold of an electric leakage current is less than 6mA. The electric leakage protection socket has complete safe protection functions, and a tripping mechanism makes contact points have large contact pressure and small contact resistance and not easy to emit heat. The breaking current capacity is large, and the tripping force can reach 2 to 3 times of that of a general electric leakage protector. A neutral line of a phase line cannot reset when reversely connected, and the phase line and the neutral line immediately trip or cannot reset after being disconnected, which has good function of protecting low-current domestic appliances. The electric leakage protection socket is the small-sized power supply socket with more reliable and stable operation.

Description

Technical field [0001] The invention relates to a power socket type leakage protector, in particular to a single magnetic type leakage protection socket with various personal and electrical safety protection functions. Background technique [0002] Power sockets are widely used in three situations: one is the terminal electrical appliances of the power grid, such as wall sockets; the second is the interface for electrical equipment to connect to the power source, such as the wiring socket set on the electrical shell; the third is the power plug Line board, which is used as electrical connection between wall sockets and electrical appliances. Most of the power sockets in the prior art do not have a safety protection function. When an electrical leakage fault occurs at the load end of the socket, a life safety accident is caused. [0003] The idea of ​​adding a leakage safety protection function to the socket to improve the safety level of electricity consumption has been around for...

AI Technical Summary

Problems solved by technology

[0003] It has been a long-standing idea to add a leakage protection function to the socket to improve the safety level of electricity consumption. However, due to the following technical problems, the existing technology has leakage protection The use effect of functional power socket is still unsatisfactory: firstly, the tripping speed of the socket is slower than the tripping speed of its upper level protector (such as circuit breaker), which does not have the function of safety protection at all.

Secondly, the leakage threshold of 30mA is far greater than the absolute safety current of the human body (about 10mA), which cannot protect personal safety
