摘要/Abstract

摘要： 脉冲电源系统性能基本取决于放电开关的特性，真空触发开关因其具有工作电压范围宽、承载电荷量高、介质恢复迅速、结构紧凑等优点，可用于脉冲电源的主开关。采用RVU-43型真空触发开关研制了一套总储能2 MJ、额定工作电压13 kV的脉冲电源。电源系统由17个118 kJ电容储能模块并联组成，单个模块短路放电最大电流达52 kA，系统包含了充电、控制、测量子系统。电源在模拟负载上进行了单模块、系统同步与时序控制放电性能测试，并在电热化学发射装置上进行了发射试验。结果表明，系统输出的电流幅值较高且波形灵活可调，可靠性高，可满足电热化学发射试验的研究。

Abstract: The performance of pulsed power supply (PPS) depends on the basic characteristics of the discharge switch. Triggered vacuum switch (TVS) has the advantages of wide working voltage range, high transfer charge, quick dielectric recovery and compact structure. A 2 MJ PPS with rated operational voltage of 13 kV which uses RVU-43 TVS was developed. The PPS is of multi-module parallel structure and composes of 17 118 kJ capacitor-based pulsed power modules. The maximum short-circuit discharge current of every module is about 52 kA. The system is composed of charging, control and measurement subsystems. The synchronous and time sequence discharge tests under dummy load are made for PPS, and PPS is launched from an electrothermal chemical (ETC) launcher. The experimental results show that PPS can output high amplitude and flexible current wave, and has high reliability for ETC launch research. Key
