一、基本情况 雷电对过河設备及操作人員有一定的威胁。据在研习班上粗略調查,全国自解放以来,有7处过河設备遭受过雷害,設备的支柱等部件有輕重不同的損坏。有4个单位曾发生过測驗人員輕微触电現象。有两个单位的纜道上发生过雷电火花。今后过河設备高度、跨度都有所增加,防雷是一个值得注意的問題。 First, the basic situation Thunder and lightning across the river equipment and operators have a certain threat. According to a rough survey in the study class, since the liberation of the country, seven river crossing facilities have been subject to thunderstorms, and the pillars and other components of equipment have varying degrees of damage. There are 4 units occurred once testers slight electric shock phenomenon. Lightning sparks have occurred on the cableway in two units. In the future, the height and span of river crossing equipment will increase, and lightning protection is a problem worth noting.
