摘　　要：对40.5kV高压开关柜绝缘故障进行统计分析,认为故障率高的主要原因是空气绝缘净距不足、绝缘材料老化、复合绝缘配合不当和绝缘材料质量较差等绝缘缺陷,并对这些绝缘缺陷进行深入分析,分别提出现场已运行和新装用40.5kV高压开关柜的处理措施。The causes for the high of 40.5kV high-voltage switchgear panel insulation fault rate is analyzed,and the main reasons are that the lack of air insulating distance,the aging of insulating material,the improper composite insulation co-ordination,the poor quality of insulating material and so on.This insulation fault is discussed,and the specific preventive measures of the new equipment and operating equipment for 40.5kV high-voltage switchgear panel is proposed.
