摘要:
分析了等离子体发生器工作时阴极电位浮动的原因及其危害,采用光导纤维传输模块测量放电电压。等离子体发生器大电流放电情况下,发生器阴极电位浮动可达800V。这种电位浮动主要是由连接阴极和高压地的通流回路的等效串联电感引起。等离子体发生器阴极浮动电位导致等离子体发生器阴阳两极间电压测量通道地电位与测量系统中其他测量通道的地电位不等,主放电回路的高电压对测量系统安全构成严重威胁。文中采用光导纤维传输模块隔离阴极电位,消除了阴极电位浮动对测量通道安全的威胁,使测量系统安全工作。
Abstract:
Factors causing the fluctuation of cathode electrical po tentia l of p lasm a generator are investigated. Op tica l fiber transm ission modu les are utilized to measure the d ischarge vo ltage. When the grea t pulsed d ischarge curren t flew through p lasm a genera tor, the variat ion o f cathode po tent ia l rose up to abou t 800 V. Thema in part of the ca thode potent ial is induced from the equ ivalen t serial inductor o f the cables connected w ith the cathode. The ground po tentia l d ifference betw een p lasma generato r vo ltage measurement channel and other vo ltagem easurement channels introduces h igh voltage into the measuremen t system w ithout any pro tection. An opt ical fiber transm issionmodule is ut ilized to separate the p lasm a generato r. s cathode potential fluctuation from themeasurem ent system and them easurement system wo rks w e ll.
