雷电是一种极具破坏力的自然现象,其电压可高达数百万伏,瞬间电流更可高达数10万安培。近年来,雷电所造成的破坏可谓不计其数。落雷后在雷击中心1.5km~2km范围内都可能产生危险过电压损害线路上的设备,特别对低压配电系统中的各种弱电设备更容易造成损坏,如电梯控制柜中的主板以及信号处理板等设备,均有很多的弱电回路。但电梯制造和安装的相关国家标准并没有对电梯的防雷做出明确的规定,且
Thunder and lightning is a devastating natural phenomenon with voltages up to millions of volts and instantaneous currents up to hundreds of thousands of amps. In recent years, the damage caused by lightning can be described as countless. Lightning over the center of 1.5km ~ 2km after the lightning strike may cause dangerous over-voltage damage to the equipment on the line, especially for low-voltage power distribution system vulnerable to more vulnerable equipment such as damage, such as the elevator control cabinet motherboard and signal processing Board and other equipment, have a lot of weak circuit. However, the relevant national standards for the manufacture and installation of elevators do not make any explicit provisions on the lightning protection of elevators and
