长效石墨防雷接地体在同煤输配电中的应用

Application of Long-lasting Graphite Lightning Protection Earthing Body in Power Transmission and Distribution of Datong Coal Mine Group

本文针对同煤矿区输配电设施大部分处于山区地段,受土壤地质的影响,纯金属和复合材料的接地体无法确保将雷电流泄入大地,导致机电设备和输配电设施易遭受雷击,造成设备损坏或大面积停电事故,给煤矿的安全生产带来了隐患等难题,根据近年来的理论和实践验证,采用长效石墨防雷接地体能够有效的解决这一难点问题。

For most power transmission and distribution facilities of Datong Coal Mine Group are in mountainous areas, affected by soil geology, lightning current cannot be ensured to discharge into the earth by earthing body of pure metal and composite, this leads to being struck of mechanical distribution facilities by lightning, causes equipment damage and electrical equipments and power transmission and or large area blackout accident, and brings the hidden danger for coal mine safety production, by theory and many times of practices in recent years, using long-lasting graphite lightning protection earthing body can effectively solve this difficult problem.
