摘要
对一起500kV套管末屏接地装置缺陷进行分析,认为自接地式末屏接地方式存在隐患,弹簧老化后弹力不够,铜套回弹不到位,是导致末屏接地不良的原因,并提出可行的预防措施。
The cause of a 500 kV bushing end shied earthing device is analyzed with defect procedure, the end shied earthing device have hidden danger,the spring ageing and e- lasticity is not enough,copper sleeve rebound is not in place leading to bad grounding, and feasible anti-defect measures are proposed.
