摘　　要：随着高电压电子系统朝着功率密度不断增加的趋势,电子部件尺寸变得更小,相互配合也更加紧密。对高电压系统中的引线电缆、连接器组件、电容、密封件和一些绝缘系统组件的高电压耐受能力的要求也变得更高起来。对于器件瞬态和稳态高电压的耐受力的关键是它必须在系统的整个工作寿命都能承受。这要求设计者和使用者对高压连接器组件中局部放电特性必须有一定的了解。持续的局部放电对高压系统组件绝缘是有害的,减少或消除局部放电是一些高电压系统中的一个设计目标。The electron components are becoming smaller and more compatible with each other along with the increasing power density of high-voltage electronic system, and demand much higher high-voltage endurance capability of lead cable, connector components,sealing compoents of high-voltage system and some components of insulated system. To the components endurance capability in twinkle state or steady state of high-voltage, what?s importance is tat, it must endure in the whole working procedure of system,which demands both designers and users must have good knowledge of the features of partial discharge in high-voltage subassembly. Continuous partial discharge is bad for the insulation of components in high-voltage system, reduce or eliminae it is a working goal for some high voltage system design.
