摘　　要：介绍了高压击穿法、多极触发法、熔丝熔爆法、活塞起弧法 4种毛细管等离子体电弧的工作原理及各自特点 :高压击穿法利用分级供电脉冲电源技术实现了电源小型化 ;多极触发法利用同轴结构优势 ,中间电极担当触发和开关角色 ,主放电回路起放大作用 ;熔丝熔爆法在两电极之间用金属线或箔连接 ,起弧电压低 ,易于起弧 ;活塞起弧法利用活动电极充当回路开关 ,电源所需电压较低。除熔丝熔爆法外 ,其它 3种方法都可重复使用 ,使用时根据需要选择。比较而言 ,多极触发起弧法可控性和重复性都较好 。This paper introduces four methods of arc building with capillary plasma such as high voltage breakdown method, a staged spring for capillary plasma arc method, wire exploding method and plug ignition method. Their working mechanism, property and their application are also analyzed and compared. The method can be selected according to the practicality. Comparing the four methods, a staged spring for capillary plasma arc has advantage of identical axis configuration. Its middle pole plays the role of touching off and turning on. Its main discharge loop has enlargement effect and also have good control characteristic and repetition. So it can be used widely.
