摘要
电力系统中的各种电气设备都有一定的绝缘等级,电力系统能否可靠工作,是否安全工作,都与其 绝缘是否被击穿有关,而电力系统在传输电力网络很多是在户外,则不可避免的要受到雷电的袭击,所以,对电 力系统中的变电所要进行防雷保护。
Each electric equipment in power system has a certain isolation grade. The savety of operation is related to integrality of isolation. It's a very common situation for power nets which is located outside to be stromed. So it is essential for us to do something to keep the transformer substation from lighting strike.
