| 摘 要： | 针对750kV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。

| Abstract: | Aiming at the problems of 750 kV isolating switch operation, analyzes the the influencing factors 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. |
