为了观察真空电弧行为的变化，建立了40.5kV/31.5kA/2500 A真空断路器（VCB）试验平台，获得了典型短路电流开断工况下电弧电压和电弧电流的变化规律。为了分析真空断路器的介质恢复特性和开断能力，对不同短路电流开断条件下的电弧能量、电弧电阻和燃弧时间进行了分析。
For observing the vacuum arc behavior variation, the experiment platform for a 40.5kV/31.5kA/2500A vacuum circuit breaker (VCB) was established and the variation of the arc voltage and arc current was obtained under the typical shortcircuit current breaking condition. Moreover, for analyzing the dielectric recovery characteristics and the interrupting capability for the VCB, the dynamic arc energy, the arc resistance and the arcing time under different short-circuit current breaking conditions was illustrated and analyzed.
