| 摘 要： | 研究了一种新的弧后电流测试方法;以较高的灵敏度和抗干扰能力测得了扩散型真空电弧的弧后电流值;给出了计算与实测的比较结果;分析了不同电源条件下的弧后电流.文中指出,扩散型真空电弧的分断极限是由电击穿决定的,而不由弧后电流引起的热击穿所定.

| Abstract: | This paper presents a new method for post-arc corrent measurement. It is suitable for diffused vacuum arcs and of fairly high sensitivity and good anti-interference ability. Meas ured and calculated results of the post-arc current level under different recovery voltage conditions are given. It has also been found that diffused vacuum arcs with a high current gives a low post-arc current and that the limitation to the breaking capacity for diffused arcs is due to electric field breakdown rather than to thermo-breakdown by post-arc current. |
