Abstract According to the characteristics of mountain areas in Wencheng County，Zhejiang Province，some effective measures reducing earthing resistance are introduced，including increasing the area of earthing net and the effective length of earthing body，deep burring the earthing body in low -resistvity soil，laying resistance -reducing agent，replacing the soil，laying underwater earthing net，earthing technology for explosion and so on.

Key words Mountain area Earthing resistance Soil resistivity Earthing net Earthing body

 

摘 要 结合浙江省文成县山区特点，介绍山区降低接地电阻的有效措施，包括增大接地网面积和接地体的有效长度、深埋接地体于低电阻率的土壤中、敷设降阻剂、换土、敷设水下接地网，以及爆破接地技术等。
