摘要
在电力系统中,断路器控制回路是二次回路的重要组成部分,是连接一次设备和二次设备的桥梁,通过断路器控制回路可以实现二次设备对一次设备的操控和低压设备对高压设备的控制。如果控制回路出现故障,将会导致断路器不能正确动作,影响系统安全稳定运行。通过对断路器控制回路进行分析,讨论了500kV阿海珐型断路器控制回路中二极管损坏所产生的风险及隐患,同时针对该风险提出了相应的解决措施。
In the power system,the circuit breaker control circuit is an important part of the secondary circuit,which is the bridge connecting the primary equipment and the secondary equipment.Through the circuit breaker control circuit,the secondary equipment can control the primary equipment and the low-voltage equipment can control the high-voltage equipment.If the control circuit fails,the circuit breaker will not operate correctly,which will affect the safe and stable operation of the system.Through the analysis of the circuit breaker control circuit,this paper discusses the risk and hidden trouble caused by diode damage in the control circuit of 500kV Areva circuit breaker,and puts forward some corresponding solutions to this risk.
