摘　　要：通过对高压分压器击穿故障模式的分析和试验研究,发现在抽真空灌注过程中,中空结构的分压器会形成局部低气压,导致分压器击穿。同时,对高压分压器的结构提出了改进设计。The experimental research of high-voltage divider's breakdown fault mode is presented. As the experimental result showes, after vacuuming and impregnating, partial low air-pressure will be formed in the divider which is a hollow structure,and will cause the divider's breakdown fault. Improved structure design of the high-voltage divider is put forward.
