贵州省乌图河一级水电站接地设计方案

针对乌图河一级水电站的接地网设计存在土壤电阻率高，可用场地小，地势险峻、地形复杂等困难因素的现状，结合其他山区水电站的接地网设计、运行经验，对乌图河一级水电站接地工程进行了设计分析，提出沿河道设置地网和在适当地区设置外延接地降阻并配合降阻剂降阻的方案。

The Grounding Design Plan of the First Wutu River Hydropower Station of Guizhou Province

Aiming at the existing problems such as： high soil resistivity, narrow usable place, rugged terrain and complex topography, which are encountered during the design of grounding net, and refering to the grounding net design and operating experience of other hydropower stations located in mountain areas, the grounding engineering of the first Wutu river hydropower station are analyzed and designed. After that, the plan of setting grounding net along river and using the method of extending grounding in order to reduce the resistance with resistance reducer is brought forward.
