断路器作用是用来断开或接通电路，是变电所以及发电厂的一种重要电气设备，它能够在电力系统发生短路故障时迅速切除故障点。在影响断路器工作性能的因素中，除了自身电气、绝缘、机械等因素外，断路器控制、保护以及二次回路接线是否合理完善等都与其工作性能有很大关系。文章对变电站中所遇到的断路器控制回路经常出现的问题及原因进行分析，并提出相应的改进方法，这些改进方法在工程实际中经过验证是可行的。

The circuit breaker is in power plant and substation is one of the important electrical equipment,used to connect or disconnect the circuit, especially in short circuit fault occurs in the power system,the circuit breaker moves quickly will point of failure removed,the circuit breaker performance besides itself,machinery,electrical insulation,but also its control two,protection and secondary circuit wiring is perfect and reasonable have great relations.Analyzes the problems and reasons of the encountered in substation control circuit of breaker often appear,and brings forward the corresponding improvement method, the improved method in practical engineering is feasible after verification.
