Analysis of Breakdown Reasons for Faults in Parallel Capacitor Components
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.
