摘要(Abstract):
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.Lightning is the main cause for insulator damage.Therefore,the insulator lightning protection devices are developed.The operation in low-voltage lines show that it can reduce the lightning trip rate and achieves the protection of insulator.
