电爆炸切断开关的实验研究

Experiment Study of Electrically Exploded Opening Switch

电感储能系统中的关键技术是切断开关技术，本文论述了导体的电爆炸机制，以及作为切断开关爆炸导体参数选取的经验公式，并设计了一种爆炸导体切断开关的装置结构，在实验中取得了较好的结果。通过调节导体参数，可得到脉宽２８０ｎｓ，电压增益达到十几倍的高功率脉冲信号，其结果对我们通过用虚阴极二极管等器件作负载来产生高功率微波有重要的意义。

Opening switch technology is the key to inductive storage system. In this paper, the mechanism of conductor's electrically exploding is discussed. The experience formula is presented to determine the parameters of the electrically exploded conductor as an opening switch. And the configuration of such an opening switch is designed. Good results have been achieved in experiment. By the adjusting of conductor parameters, high power pulse signals are generated with the duration of 280ns and the voltage gain of several tens. It is showed that this kind of opening switch can play an important role in high power microwave generation with such device as vircator used as the load.
