【摘要】：脈沖電源系統(tǒng)性能基本取決于放電開關(guān)的特性,真空觸發(fā)開關(guān)因其具有工作電壓范圍寬、承載電荷量高、介質(zhì)恢復(fù)迅速、結(jié)構(gòu)緊湊等優(yōu)點(diǎn),可用于脈沖電源的主開關(guān)。采用RVU-43型真空觸發(fā)開關(guān)研制了一套總儲(chǔ)能2 MJ、額定工作電壓13 k V的脈沖電源。電源系統(tǒng)由17個(gè)118 k J電容儲(chǔ)能模塊并聯(lián)組成,單個(gè)模塊短路放電最大電流達(dá)52 k A,系統(tǒng)包含了充電、控制、測(cè)量子系統(tǒng)。電源在模擬負(fù)載上進(jìn)行了單模塊、系統(tǒng)同步與時(shí)序控制放電性能測(cè)試,并在電熱化學(xué)發(fā)射裝置上進(jìn)行了發(fā)射試驗(yàn)。結(jié)果表明,系統(tǒng)輸出的電流幅值較高且波形靈活可調(diào),可靠性高,可滿足電熱化學(xué)發(fā)射試驗(yàn)的研究。
[Abstract]:The performance of pulse power supply system basically depends on the characteristics of the discharge switch. The vacuum trigger switch has the advantages of wide working voltage range, high load charge, rapid dielectric recovery, compact structure, etc. A set of pulse power supply with total energy storage 2 MJ and rated working voltage of 13 kV is developed by using RVU-43 vacuum trigger switch. The power supply system is composed of 17 118kJ capacitive energy storage modules in parallel. The maximum short-circuit discharge current of a single module is up to 52 Ka. The system includes charge, control and measurement subsystem. The power supply has a single module on the analog load, and the performance of the system synchronization and timing control discharge is tested. The results show that the output current amplitude of the system is high, the waveform is flexible and adjustable, and the reliability is high, which can satisfy the research of electrothermal chemical emission test.
