| 摘 要： | 针对地处山坡或山顶的输电线路经常出现雷电绕击导线引起线路跳闸的现象,以“闪击距离”的概念为理论基础,在220 kV线路杆塔上采取装设负角保护针的措施,有效地防止了输电线路遭受雷电绕击,大大地降低了线路跳闸率,提高了输电线路安全运行水平。

| Abstract: | Transmit electrical wire perchs on the hillside or on the top of the mountain often come forth the thunder rounds the overhead wire and attacks lead.Installing the negative angle protective pin on the 220 kV circuitry hillside or excessive mine field on the top of the mountain and easy attacking perch tower,can reduce the thunder circle attacking of the transmit electric circuitry and can lower the circuitry lightning strike trip ratio and can improve the circuitry safety operation level. |
