带有涌流抑制装置的断路器工作原理分析和改进

Analysis and Improvement of the Working Principle of the Circuit Breaker with Inrush Current Suppression Ddevice

为防止操作断路器时产生过电压和涌流,一些工业用户站中会加入涌流抑制装置,这就使得断路器的操作回路变得复杂,本文通过分析带有涌流抑制装置的断路器操作回路的原理,指出其存在的缺点,并提出了改进措施。

In order to prevent over-voltage and inrush current when operating the circuit breaker,some industrial user stations will add inrush current suppression device,which makes the operation circuit of the circuit breaker more complex.This paper analyzes the principle of the operation circuit of the circuit breaker with inrush current suppression device,points out its existing shortcomings,and puts forward improvement measures.
