摘要
出于开关性能参数和结构要求考虑,PTS装置脉冲输出开关设计为3对自击穿电极间隙的水介质开关,间隙结构采用板-球间隙的同轴-三平板结构。选择水介质自击穿开关作为研究对象,进行了1.5 MV同轴结构开关研究,并在此基础上开展了4MV同轴-三平板结构开关研究。开关实验达到的技术指标为:自击穿电压3.5MV,导通电流500kA,电感65nH,自击穿时间分散性极差4.0ns(1.3ns均方根值)。
The self-breakdown water switch with coaxial-triplate configuration is used for the pulse output switch of the pulse forming section in Primary Test Stand (PTS). The research contains two stages, the first is the 1. 5 MV coaxial water switch experiment on FLASH-Ⅱ and the second is the experiment of 4 MV coaxial-triplate multi-channel water switch on the pro- totype module of PTS. Results show that the output current is 500 kA with 100 ns rise time at 3.5 MV self-breakdown voltage, the total switch inductance is 65 nH, and the jitter of charging time is 1.3 ns.
