亭子口枢纽电站接地网测试研究与处理

Study and Treatment of Grounding Grid Measuring of Tingzikou Water Control Project

亭子口接地网是由垂直和水平接地极组成的兼有泄流和均压作用的水平网状接地装置,等效面积在5000m2以上。为保障亭子口水利枢纽电站的安全、稳定运行,对接地网的接地装置电气完整性、跨步(接触)电位差及接地阻抗进行了测试,测试结果均满足国家标准和行业标准规定。

The grounding grid of Tingzikou water control project is a horizontal net-like grounding connection with the functions of discharging and equalizing effect. The grounding grid consists of vertical and horizontal grounding electrodes and the equivalent area is more than 5 000 m2. For guaranteeing the safe and stable operation of Tingzikou Hydropower Station, the electrical integrity, step （contact） potential difference and ground impedance of grounding connection are tested. The test results show that the grounding grid meets the requirements of state and industry standards.
