架空输电线路高土壤电阻率地区接地模块的应用

摘要

Reducing the grounding resistance of tower grounding device is an important measure to im- prove the lightning withstand level of transmission lines. For the line towers in many stones and less soil mountain areas, using the traditional method of resistance reducing agent, grounding resistance and envi- ronmental protection are difficult to meet the requirements. This paper introduces the characteristics, the- ory of reducing resistance and application of grounding module, pointing out that an alternative resistance reducing agent in order to grounding module can not only effectively reduce the grounding resistance of tower grounding devices, while receive good environmental effects.%降低杆塔接地装置的接地电阻是提高输电线路耐雷水平的一项重要的措施,对于多石少土山区线路杆塔,用传统的降阻剂降阻方法,接地电阻和环保都很难达到要求。文章介绍了接地模块的特点、降阻原理和应用,指出以接地模块替代降阻剂,不仅可有效地降低杆塔接地装置的接地电阻,同时收到良好的环保效果。
