The paper investigates the influence of the pulsed AMF arc control on the vacuum arc and the post arc characteristic to reveal the mechanism of AMF arc control in different control time and find the proper AMF arc control. The pulsed AMF control system is designed and the pulse width is adjusted from 1.5 ms to 10 ms by changing the capacitors. The test circuit is set up in the synthetic test circuit...

This paper proposes the equivalent circuit of dynamic VD (PVD) in multi-break vacuum circuit breakers (VCBs). The equivalent circuit is composed of controlled post-arc sources, post arc resistors and equivalent capacitors. The PVD is divided into four processes: the initial transient recovery voltage (TRV) process, the oscillating TRV process, the stable TRV process and the power-frequency voltage...
