山区变电站接地设计

Grounding Design for Mountainous Area Substations

山区变电站由于地质原因,土壤电阻率高的情况比较普遍,给变电站的主接地网的设计带来一定难度,对此需要采取相应的降阻措施。针对常规降低变电站接地电阻的几种方式进行分析及比较,提出适用山区小型变电站的接地降阻方法。

Due to geological reasons, mountainous area substations usually have high soil resistivity, which brings about a certain difficulty in designing the main substation grounding network, and hence requires the corresponding resistance reduction measures. By comparing the conventional methods to reduce substation grounding resistance, this paper proposes the grounding resistance reduction method suitable for small-scale substations in mountainous areas.
