断路器防跳回路与跳位监视回路现场应用问题分析及改进

Analysis and Improvement of Field Application of Circuit Breaker Anti-pumping Circuit and Open-position Monitoring Circuit

为防止断路器"跳跃",必须配置断路器防跳回路。实际应用中,断路器防跳回路与跳位监视回路需进行合理设计,否则两者容易出现配合问题。本文以现行反措和技术规范为依据,对断路器防跳回路和跳位监视回路现场应用典型问题进行分析,并提出改进技术方案。

In order to prevent the circuit breaker from "jumping",it is necessary to configure circuit breaker anti-pumping circuit.Circuit breaker anti-pumping circuit and open-position monitoring circuit need to be designed reasonably in practical application.Otherwise,the combining problem in both of them appears easicy.Based on the current countermeasures and technical specifications,this paper analyzes the typical problems of the circuit breaker anti-pumping circuit and open-position monitoring circuit on-site application and proposes an improved technical solution.
