摘要:

在电热、电磁发射技术中，高功率脉冲电源占据着非常重要的位置，开关是高功率脉冲电源的重要组成部分。该文介绍了大功率空气开关的特性及主要结构特点，着重介绍了ＨＧ－１００型空气开关的设计及特性，分析了空气开关存在的问题及改进方向。研究表明，从触发脉冲加入瞬间到电导等离子体开始形成阶段，决定着空气开关的动作时间和稳定性；在间隙中形成高电导率的等离子体的速度决定了脉冲前沿的徒度；脉冲功率电源稳定工作的极限频率取决于间隙绝缘强度的恢复时间。

Abstract:

In the elect rothermal chemical and electromagnetic launch technolog y, the hig h-pow er pulsed sour ces o ccupy a very impo rtant place. The sw itch is an important part of the high-power pul sed sour ces. This paper intr oduced the characterist ic and the main co nstr uct io n of the high-power g as sw itches. It int roduced especially design and feature of HG-100 g as sw itch and analy zed it s problems and improv ement s of gas sw itches. Research made it clear that the instant addition in t rigg ering pulse to the electr ic plasma decided the act ion t ime and the stability of the sw itches. T he velocity of high-elect ric co nduct iv ity plasma in the gap decided the gr adient of pulse. The limit frequency of the stable act ion of the pulsed pow er so urce depended on the reinstated time of the gap insulation.
