摘要
兰州东变电站750kV一次设备选用GIS产品,目前其I段母线为国内750kV运行GIS设备中最长的封闭母线,安装结束后多次发生母线筒连接面漏气等缺陷。笔者通过对固定支架、温补伸缩节位移量进行分析,发现缺陷原因主要为固定支架设计及温补伸缩节安装调整存在问题,最后针对存在问题提出了相应的改造建议。
Lanzhoudong substation 750 kV change a selection of GIS equipment,products,currently the I paragraph 750 kV busbar for domestic GIS devices to run up the closed bus,install a number of bus after the end of tube connection,such as surface leakage fault.Based on an analysis of anchors and bellows displacement,the main reason for the defects found anchors design and bellows adjustment problems.Finally,there is a corresponding transformation put forward proposals.
