由野外安防前端设备防雷接地问题引发的思考——浅析室外用电设备的接地设计

Thinking Caused by Lightning Grounding Problem of Front-end Equipment of Field Security System——Brief Analysis about Grounding Design of Outdoor Electric Equipment

结合野外实际安防系统前端设备防雷接地设计,从直击雷防护、感应雷防护、电击防护等各方面对室外用电设备的接地设计进行探讨,根据配电系统不同接地形式对接地电阻的要求进行分析,对接地极的设计要点计进行论述,提出一种将室外设备人工接地极和等电位联结有效结合的思路。

In accordance with thelightning grounding design of the front-end equipment of practical security systems,this article introduces the grounding design of outdoor electric equipment from the aspects such as direct lightning protection,inductive lightning protection and protection against electric shocks,analyzes the requirements of the different tgrounding methods of power ddistribution systems for ground resistances,points out the design essentials of grounding electrodes and proposes an idea to combine the artificial grounding electrodes and equipotential bonding of outdoor electric equipment.
