带电更换110kV隔离开关是解决隔离开关故障率较高,保持变电站供电可靠性的重要措施之一.带电更换110kV隔离开关主要技术难点是:作业空间不足,作业位置不佳,作业过程中电场对人的影响的理论参考资料不足.文中通过对某110kV变电站GW5型隔离开关进行建模,对作业过程进行仿真分析,表明带电作业过程中不仅带电作业人员需要穿屏蔽服,地面工作人员也需采取防护措施,解开隔离开关第二个分流线线夹时会发生电弧放电,需采取相应防护措施.

To replace the 110 kV disconnector without power outage is one of the major measures to address the high failure rate of disconnector,maintaining the high power supply reliability of substation.The main technical difficulties of live working include poor operating space and operating position,lack of theoretical knowledge of live working.This paper models GW5 type of 110 kV disconnector,and simulates the process of live working.The results show that not only the workers who do live working must wear shielding clothing,but also the workers on ...
