中文摘要: 分析并处理了一起雷击引起的变电站开关柜短路故障,通过现场试验,判断其原因是线路杆塔接地电阻较大,站内开关柜内绝缘板憎水性能不佳,以及引线排未进行绝缘化处理所致.从改善线路杆塔接地电阻、变电站开关柜内绝缘板憎水性,以及引线排绝缘化等几个方面提出了切实可行的防范措施,对预防此类由于雷击导致变电站开关柜绝缘被击穿故障提供了参考.
Abstract:Substation switchgear short-circuit fault caused by lightning is analyzed and solved. Through field test, large tower grounding resistance of line, poor hydrophobic performance of insulation board and lead row without the insulation processing in switchgear are the causes of the fault. Finally, some feasible preventive measures are put forward in terms of improving tower grounding resistance of line, the insulation board hydrophobicity and lead row insulation in switchgear and so on, which to preventing switchgear insulation breakdown fault in substation caused by lightning line is of positive significance.
