高压断路器防跳及监视回路的方案分析

Analysis of Scheme of High Voltage Circuit Breaker Anti-trip and Monitoring Loop

通过分析操作箱防跳及机构防跳两种断路器防跳原理,对国内主流厂家高压断路器防跳及监视回路进行分析比较,提出适用于智能变电站的防跳及监视回路的方案。

By analyzing the anti-trip principle of two kinds of circuit breakers including anti-trip of the operation box and anti-trip of mechanism,this paper analyzed and compared the anti-trip and monitoring loop of high voltage circuit breakers in domestic mainstream manufacturers,and proposed a scheme for anti-trip and monitoring loops for smart substations.
