Problems solved by technology

Its defect is that the self-diagnosis ability of the fault is poor, there is no memory ability after a power failure, and the limit of the overload current is not determined according to the load of the actual electrical equipment, that is, the overload current cannot be adjusted according to the power consumption situation, which makes this kind of It is inconvenient and timely to maintain the circuit breaker during use, and the actual effect of overload protection is not ideal; in addition, due to the use of bimetallic strips, its technical parameters are difficult to guarantee, and the production process is difficult. change makes difference

Abstract

A mechanically linked breaker features that the electronic circuit and mechanical structure are combined to treat over-load and leakage signals for automatically cutting circuit off, the tripping device and indicator are linked to display the over-load and leakage failures, and the rated current can be regulated for meeting actual load of electric appliances. Its advantages are novel, unique and simple structure, high power and effect and low cost.

Description

technical field [0001] The invention relates to a circuit breaker, belonging to electrical appliances. Background technique [0002] Before the present invention was made, the existing circuit breakers were usually thermal magnetic circuit breakers. Its defect is that the self-diagnosis ability of the fault is poor, there is no memory ability after a power failure, and the limit of the overload current is not determined according to the load of the actual electrical equipment, that is, the overload current cannot be adjusted according to the power consumption situation, which makes this kind of It is inconvenient and timely to maintain the circuit breaker during use, and the actual effect of overload protection is not ideal; in addition, due to the use of bimetallic strips, its technical parameters are difficult to guarantee, and the production process is difficult. Variation produces difference. Contents of the invention [0003] The purpose of the present invention is ...
