石油天然气井站防雷设施分析和探讨

Analyse and Approach on Lightning Protection Facilities Used in Petroligenic Natural Gas Station

目前,现有的石油天然气井站为了避免采输设备、电气设施遭雷击或爆炸,不仅安装了避雷针,而且对各类设备还做了接地等防雷防爆处理。文章根据井站避雷的实际情况,对避雷装置的类型、工作原理、安装要求以及防雷设施的接地情况进行了分析,找出了其中存在的不足并提出了一些合理的建议。

At present, all types of equipments used in petroligenic natural gas station have been equipped with lightning rods and earthings in order to prevent from lightning strike, even if explosion for petroleum production and conveyer equipments and other electrical facilities. Based on the practical situation of lightning protection in these oil stations, this paper presents the forming cause, influence and dangers of lightning stroke, and explicates the types, principle of work, installation requirements of the lightning protection devices, as wen as the earthing methods, finds out the insufficiencies of these measures and put forwards some rational suggestions.
