摘要
变电站接地网可靠接地对维护变电站安全、可靠运行,保障运行人员及全站电气设备安全至关重要。介绍了750 kV银川东变电站的系统接线及接地网施工概况,分析了接地网施工中应注意的问题及这些问题对日后变电站可靠运行带来的安全隐患,提出了需要改变仅强调降低接地电阻来保障安全的传统观念,树立了考虑地面电位分布不均及其相关问题所带来危险的新观念。最后通过工程验收结果,提出了相应的监督体制及改进措施,以供同行借鉴。
Substation＇s grounding grid is very important to substation＇s security and ensures the safety of power equipment and personnel： This paper introduces the system connection and grounding grid project of 750 kV Yinchuandong substation, and analyses grounding project issues which may bring hidden troubles. It brings forward new concept and considers floor potential distribution, which breaks only changing ground-resistor for ensuring safety. It proposes relavant control system and improved measure as reference for others.
