- And it is certified that the device is very useful to prevent insulated overhead line breakage and insulator damage from lightning overvoltage faults. 作为配电线路中的架空绝缘电缆的过电压保护装置,可有效地防止雷害造成的断线、绝缘子损坏等事故,避免因断路器动作中断供电而影响供电可靠性。
- Usually,a high voltage is carried by the overhead-wire system,and the third rail has current at a much lower voltage. This is because of the danger that a man on the line might touch the electric rail,but he can not touch an overhead wire. 通常,高压电被高架线系统输送,第三根铁轨里的电压则是很低的,这是因为如果一个站在线路上的人就可能碰到电轨,那是很危险的,但是他不可能碰到高架线。
