浅谈110kV变电站接地电阻超标问题及改造

Mainly Talks about the 110 kV Substation Grounding Resistance Paint and Modification

接地系统是变电站的重要组成部分,它时变电站的安全、稳定运行具有重要的影响,而接地电阻的大小是安全接地的重要指标。因此,接地电阻必须要满足变电站的安全运行要求。结合实践,就110 kV变电站接地电阻超标问题进行了详细阐述,并给出了具体的改造方案,经校验后达到了变电站安全运行的要求。

Grounding system is an important component of the substation, it is important for the safe and stable operation of the transformer substation, and the size of the grounding resistance is an important index of safety grounding. Therefore, the grounding resistance must satisfy the requirement of the substation safe operation. Combined with the practice, on the 110 kV substation grounding resistance paint in detail, and gives the concrete, retrofit scheme, has reached the requirement of transformer substation safe operation after checking.
