1100kV特高压变电站接地电极接头质量控制和检测

Quality Control and Detection of Grounding Electrode Connector in 1100kV UHV Substation

接地电极对接地电网的安全起着非常重要的作用,接地电极及其线路是直流输电系统中的一个重要组成部分,接地电阻的大小是安全接地的重要指标。本文重点介绍昌吉—古泉±1100k V特高压变电站工程接地电极接头质量控制和检测。

The grounding electrode plays an important role in the safety of the grounding grid. The grounding electrode and its circuit are an important part of the HVDC transmission system. The size of the grounding resistance is an important indicator of the safety grounding. This thesis focuses on the quality control and detection of grounded electrode joints for the Changji-Guquan ± 1100 k V UHV substation project.
