多通道伪火花开关及其触发技术

Multichannel Pseudospark Switches and Triggering Technology

总结了多通道伪火花开关的优点 ,对直线、同轴和径向型多通道伪火花开关的结构和特点作了综述。采用多通道结构后 ,伪火花开关的触发问题较单通道时更为复杂 ,分析了多通道开关对其触发电路的特别要求 ,并介绍了国外的研究成果。

A fundamental problem of pseudospark switch PSS is erosion in the borehole area. One way to reduce erosion is to distribute the electric current in several discharge channels. This paper summarizes the advantages of multichannel PSS, and then introduces the structure and feature of three types linear system, coaxial system and radial system of multichannel PSS. For the triggering methods, the paper analyzes the difference of triggering circuit between single PSS and multichannel PSS, some important research results are given.
