摘　　要：为保证高压试验的测量准确度和人身安全,高压试验厅要求具有良好的接地系统。系统地对接地网面积、水平接地网格数、垂直接地体的间距、垂直接地体的长度对接地电阻的影响进行了比较和分析。提出高压试验厅的接地必须采用以水平接地为主、与垂直接地体配合的复合接地形式。对高压试验厅的接地系统设计应注意的问题和措施进行了介绍。To ensure the accuracy measurment of the high voltage test and the personal safety, it was deman- ded that the high voltage test hall should have a very good grounding system. The influence on the grounding resist- ance of the grounding grids area, the number of the horizontal grounding grids, the distance between the vertical grounding bodies and length of these bodies were systematically compared and analyzed. The idea that a compound grounding system should be installed for the high voltage test hall was pointed out. The horizontal grounding is the main part in the compound grounding system, which combined vertical grounding bodies. The problems and meas- ures which should be noticed in the design of grounding system for the high voltage test hall were also put forward.
