东破35kV变电站防雷接地改造

Lightning Protection Ground Modification for the 35kV Substation of East Crusher

东破35k V变电站位于德兴铜矿铜厂采区南麓,地处山区,变电站及供电线路容易遭受雷击,造成跳闸事故,通过分析现有防雷接地措施存在的问题,提出应用脱扣式避雷器、铜覆钢接地极以及四极法测量接地电阻等防雷技术,优化变电站接地网施工技术,有效提升了采区供电设备的防雷水平,保障生产供电稳定,为山区易受雷击工况条件下供电设备防雷接地技术提供了参考经验。

The 35kV substation of East Crusherin Dexing Copper Mine is located in the south of Tongchang Open pit,since the location is in the mountainous area,the substation and charging line are easy to be suffered by lighting stroke to cause stripping accident.By analyzing the existing problems of lightning protection grounding measures,the application of lighting protection technology such as tripping arrester,copper clad steel ground electrode is put forward.Optimizing the substation ground network construction technology,the lighting protection level of open pit power supply equipment is improved,the security production power supply is stable and power supply equipment for mountain area vulnerable to lightning operating conditions grounding technology provides reference experience.
