Abstract

A capacitor cell (120 kJ and 50 kV) is intended for application in a large capacitive energy storage with a stored energy of several megajoules. A double-circuit capacitor cell that consists of “fast” and “slow” discharge circuits is proposed and substantiated. The fast discharge circuit involving a capacitor with a relatively small stored energy and a fast pseudospark discharge current switch provides a given voltage front duration at the load of 100 ns at most. The slow circuit with the main capacitor bank and a triggered vacuum switch can generate a current pulse with an amplitude of up to 500 kA at a specified current front duration of up to 10 μs. The capacitor cell design is described, and the research results of the transient processes during the cell discharge are presented, including those for high frequency oscillations in a 20-m-long cable line, which connects the capacitor cell with the load. The results of testing the capacitor-cell prototype are presented.

一种强制导通的电容器电池

电容电池（120kj和50kv）用于存储能量为几兆焦耳的大型电容储能。提出并证实了一种由“快”和“慢”放电电路组成的双回路电容器电池。快速放电电路包括一个存储能量相对较小的电容器和一个快速伪火花放电电流开关，在负载不超过100ns时提供给定的电压前持续时间。采用主电容组和触发真空开关的慢速电路可以在10 μs的指定电流前持续时间内产生振幅达500 kA的电流脉冲。介绍了电容器电池的设计，并给出了电池放电过程中的瞬态过程的研究结果，包括连接电容器电池与负载的20米长的电缆线中的高频振荡。给出了电容电池样机的测试结果。
