沿海多雷地区低压线路绝缘子的保护

Protection of Insulator for Low-voltage Lines in Lightning Prone Coastal Areas

绝缘子既要有良好的电气绝缘性能,又要有足够的机械强度,而雷击是绝缘子损坏的主要原因。为此,研发了绝缘子防雷保护装置,在低压线路上的安全运行表明,能减少线路雷击跳闸次数,对绝缘子起到保护作用。

It needs not only good electrical insulation properties but also adequate mechanical strength. Light- ning is the main cause oped. The operation in tection of insulator. for insulator damage. Therefore, the insulator lightning protection devices are devel- low-voltage lines show that it can reduce the lightning trip rate and achieves the pro-
