摘要
并联电容器广泛采用带有内熔丝的油浸电容器,电容器元件击穿是电容器故障的主要形式.电容器元件击穿的机理和原因比较复杂,不同类型的击穿需要采取不同的改进措施.通过解剖大量的故障并联电容器,对元件故障击穿位置进行了分类,结合电容器元件的结构和生产工艺,将元件击穿的位置分为电极端部、圆弧折弯处以及中心位置 3 个类型.3 个类型的击穿位置对应 3 种不同的击穿机理,针对不同的击穿类型提出了改进措施.
Abstract
Oil immersed capacitors with internal fuses are widely used in parallel capacitors,and capacitor component breakdown is the main form of capacitor failure.The mechanism and causes of capacitor component breakdown are quite complex,and different types of breakdown require different improvement measures.By dissecting a large number of faulty parallel capacitors,the breakdown positions of the components were classified.Combined with the structure and production process of capacitor components,the breakdown positions of the components were divided into three types:electrode end,arc bending,and center position.Three types of breakdown positions correspond to three different breakdown mechanisms,and improvement measures are proposed for different types of breakdown.
