摘　　要：输气站场对接地电阻的要求很高,对于某些土壤电阻率较高及受到地网范围限制的独立接地,采用常规的接地装置往往很难达到预期的接地电阻要求。文章详细分析了常用的几种降阻材料的构成、降阻原理、使用效果和特点,重点介绍了在西气东输二线西段站场应用的电解离子接地极的特点和使用效果。Gas station needs a strict requirement for grounding resistance. If some independent groundings in high earth resistance area and limited earth mat area adopt traditional materials and devices, the grounding resistances can’t reach expectative values. The composition, working principle, application results and characteristics of several resistance reducing materials for grounding are analyzed in detail. The characteristics and application results of electrolytic ion grounding electrode used at stations of west section of Second West to East Gas Pipeline are especially introduced.
