固体绝缘开关柜隔离开关模块绝缘特性研究

open access: yesGaoya dianqi
在固体绝缘开关柜的研发过程中,高绝缘水平的优化设计是其安全可靠运行的保障。文中设计了一种适用于固体绝缘开关柜的隔离开关模块,并通过试验验证了其在75 kV(合闸)、85 kV(断口)雷电冲击电压下的绝缘性能,满足国家标准要求;但当雷电冲击电压等级提高到西班牙、澳大利亚等地区标准要求的95 kV时,型腔内接地端部处发生沿面放电。采用有限元软件对其进行电场仿真与分析,由仿真结果得知型腔内接地端部空气场强发生畸变,原因在于屏蔽罩与环氧内层的绝缘距离不足,造成气固交界面的空气场强超过临界值,引发沿面放电 ...
