摘要

介绍了一种基于介质表面击穿点火系统的脉冲真空电弧等离子体源的设计,并阐述了其工作原理。在工程等离子体源中,采用四段阳极和等量的引弧段。此外,主脉冲电弧放电和引弧电路均采用单独的供电电路。该装置的每个部分都是独立运行的,基本上构成了四个脉冲等离子体源的组合,控制系统保证了它们的协调运作。脉冲等离子体源的实际试验表明,它具有以下优点:点火系统寿命提高了四倍;实现阴极工作面均匀损耗;并且,在特定条件下,提高等离子体源的生产率。

LONG-LIFE PULSED VACUUM-ARC PLASMA SOURCE
The design of a pulsed vacuum-arc plasma source with an ignition system based on dielectric surface breakdown is presented and the principle of its operation is described. In the engineered plasma source, a four-section anode is used along with an equal number of arc ignition sections. Additionally, separate power supply circuits are employed for both the main pulsed arc discharge and the arc ignition circuit. Independent operation of each section of this device is carried out, essentially constituting a combination of four pulsed plasma sources in one, the coordinated functioning of which is ensured by the control system. Practical tests of the pulsed plasma source have revealed its advantages as followed: a fourfold increase in the ignition system life-time; achieving uniform depletion of the cathode working surface; and, under specific conditions, enhancing the productivity of the plasma source.
