Smart leakage protection switch

Abstract

The invention discloses a smart leakage protection switch which comprises a leakage protector with an electric operating mechanism, a protection controller and a bypass switch. The leakage protector is the basic structure of the smart leakage protection switch to achieve leakage and overload protection. The protection controller is configured to test a leakage protection function without causing power outage to the user. The bypass switch is used as a bypass to supply power to the user when the leakage protection function is tested by the leakage protector. The smart leakage protection switchdoes not cause power outage when testing the leakage protection function of the leakage protector, and can periodically and automatically detect the leakage protection function.

Description

technical field [0001] The invention relates to a relay protection device in the technical field of power distribution and power supply, in particular to an intelligent leakage protection switch. Background technique [0002] In daily life or in factory power supply and distribution systems, the application of leakage protectors is very common. Leakage protector is a protective device that disconnects the leakage protection switch when electric leakage is detected or people get an electric shock, so that people are out of danger. There are generally two types of leakage protectors, one is a switch that integrates the leakage protection module and the overcurrent protection module, and the other is a separate leakage release that uses its linkage rod to drive the overcurrent protection switch to open. A leakage release with application number 201720127633.8 is a single leakage release. A leakage circuit breaker with application number 201310420543.4 is an integrated leakage...

Problems solved by technology

[0003] In the application process of leakage protectors, it is a well-known common sense to conduct leakage function tests, and in the process of leakage protection function tests, the opening of circuit breakers or leakage protectors is an essential process, so it will cause users Side power outages cause inconvenience to electricity consumption

In factories, power outage due to leakage detection function will affect production and reduce production efficiency

Failure to detect the leakage protector will cause hidden dangers in safe use of electricity
