变电站接地技术研究

根据城市轨道交通工程的特点,分析高土壤电阻率及大系统短路容量给主变电站接地技术方案带来的问题,并提出了相应的解决方案,为类似工程接地技术方案的设计、实施提供参考。

The influence of main traction substation grounding technology brought by high soil resistivity and short circuit capability of large scale system was analyzed on base of characters of urban rail transit. The solution for the project was a reference for following design and realization of grounding technology in similar engineering.
