110 kV智能站终端的第二组控回断线信号回路分析与完善

Analysis and Improvement of the Second Group of Control Circuit DisconnectionSignal Circuit of 110 kV Intelligent Station Terminal

在110 kV智能变电站建设过程中,主变保护回路双重化的要求带来了一系列回路完善的问题。针对双重化配置下断路器第二套智能终端的位置监视回路不完善问题,分析常规站实现方式,对比现有回路存在的问题,提出解决方案。

In the construction process of 110 kV intelligent substations,the requirement of dual protection circuit of main transformer brings a series of problems of circuit perfection.In view of the imperfect position monitoring circuit of the second set of intelligent terminal of the circuit breaker under the dual configuration,the implementation mode of the conventional station are analyzed,the problems existing in the existing circuit are compared,and solutions are proposed.
