500 kV变电设备带电水冲洗方法的研究

摘要

针对500 kV电压等级隔离开关、断路器、电流互感器等典型变电设备，进行了带电水冲洗方法的探索研究。通过对试验数据的分析和冲洗效果的比较，总结出一套针对500 kV变电站内典型设备的冲洗方法，并在500 kV王店变电站进行了现场带电冲洗实践，效果良好。%A research has been done on hot washing methods for 500 kV power transformation equipment, such as insulating switch, circuit breaker and current transformer. By analyzing test data and comparing the washing effects, the paper summarizes a hot washing system for 500 kV typical power transformation equip-ment. The system is used for field hot washing in 500 kV Wangdian substation and achieves favorable effect.
