Controlling circuit of inleakage protector with life-stop indicator and releaser

Abstract

A creepage protector controlling circuit with the end-of-life indication or trip, the characteristic is: adds the abnormity monitor circuit that can monitor the self-fault of the creepage protector automatically, indicates the fault automatically or trip directly when the key parts appears abnormity, in order to prevent electro-security accident and the person security when the creepage protector abates.

Description

Technical field [0001] The invention relates to a leakage protector control circuit with end-of-life indication or tripping. Background technique [0002] The existing household leakage protection circuit breakers on the market will only trip when the leakage occurs, and the leakage protector as a product itself is helpless when it fails. Once this happens, the leakage protector itself is damaged, then Even if a leakage occurs, the leakage protector cannot be tripped normally, resulting in undue personal injury or property loss. Contents of the invention [0003] In order to overcome the above-mentioned problems in the prior art, the object of the present invention is to provide a control circuit of a leakage protector that can indicate in advance or trip directly when the leakage protector itself is abnormal. [0004] The technical scheme adopted by the present invention to solve the technical problem is: the main input lines 1H, 2N pass through the inductor L1, the capa...
