摘要

笔者分析了白沙微波站在雷雨天气中多起事故的原因

总结出其是由于接地网接地电阻值过高引起的。针对第一次地网改造措施后接地电阻值超标等情况

对设计和施工的不合理之处进行研究。在土壤电阻率极不均匀和土地有限的前提下

从降低接地网的雷电冲击接地电阻、防腐和完善地网均压措施等方面出发

采取以树杈状的多个外延地网联合接地降阻的措施

达到接地电阻小于5Ω的改造目的。工程验收测试表明

此次改造在降阻和均压等方面效果显著。

Abstract

By analyzing several accidents at Baisha Microwave Station in lightning storm weather

conclusion was drawn that these accidents were caused by the large grounding resistance.For the grounding resistance exceeding standard

the unreasonable design and construction of the existing grounding grid were investigated.Consequently

in consideration of the awfully uneven soil resistivity and limited land

multiple tree-like extension grounding grids were adopted to reduce the grounding resistance on the premise of reducing grounding resistance

preventing corrosion and improving voltage sharing of the grounding grid.After the reconstruction

the grounding resistance of the grounding grid gets to the goal of smaller than 5 Ω with better voltage sharing property.
