低压微型断路器的机构分析

Mechanism Analysis of Low Voltage Miniature Circuit Breaker

断路器的机构是断路器的重要组成部分,决定了触头压力、脱扣力、超程、开距,以及断路器分闸、合闸、脱扣的可靠性。随着低压电器的不断发展,断路器的机构也在不断创新。以微型断路器为例,初步分析了其机构的组成、动作和受力情况。

The mechanism of circuit breaker is an important part of the circuit breaker, contact pressure, tripping force, super way, distance, and circuit breaker tripping, closing and tripping of the reliability. With the continuous development of low voltage electrical apparatus, the circuit breaker＇s mechanism is constantly innovating. In this paper, a miniature circuit breaker is used for the analysis of the structure, action and the force of the mechanism.
