地铁地下110 kV主变电站综合接地网的施工方法

Construction method of comprehensive grounding grid for underground 110 kV main substation of underground railway

随着经济高速发展和城市化进程的日渐加快,导致中心城区用地紧张,地铁主变电所作为城市电网的用户,进出线回路少,全地下变电站成为一种有效的解决方式。变电站的接地系统直接关系到变电站的正常运行,更涉及到人身和设备的安全。因此,综合接地网的施工技术作为变电站建设方面的重要环节,必须加强管理。

With the rapid development of economy and the accelerating process of urbanization, the urban land use is tense. As the user of the city power grid, the main substation of metro is less and the whole underground substation becomes an effective way to solve the problem. The grounding system of substations is directly related to the normal operation of substations, but also to the safety of human body and equipment. Therefore, comprehensive grounding network construction technology as an important part of substation construction, we must strengthen managenlent.
