针对750 kV隔离开关操作存在的问题
从干扰电压的产生及隔离开关位置不易观测等影响因素加以分析
提出了改进的措施。改造结果表明:隔离开关电机二次回路中采用屏蔽电缆
有效地减少了干扰电压
避免了隔离开关分/合闸时因电机电源跳闸引起长时间扯弧而损坏设备的情况发生
保证了电网的安全可靠运行。
Aiming at the problems of 750 kV isolating switch operation
analyzes the the influencingfactors such as interference voltage and the isolating switch position
puts forward improving mea?sures. The result shows that using shielded cable in secondary loop of electric motor of disconnector
reduces effectively the interference voltage
avoids striking of arc long time when switch off/on of iso?lating switch and ensures power grid operation on the safe side.
