Starting from a transient equivalent model of a triple-break 126 kV vacuum circuit breaker (VCB) containing a dielectric reignition criterion, the reignition current waveform of the vacuum interrupter (VI) which took over the higher part of the transient recovery voltage (TRV) was simulated. A series damped resistor was added in the grading capacitor branch to extinguish the reignition current as...
To keep the uniform distribution of the transient recovery voltage (TRV) across each vacuum interrupter (VI) is very important for the breaking capability of double-break vacuum circuit breakers (VCBs). According to the transient equivalent circuit of double-break VCBs, a mathematical model describing the TRV distribution characteristics was established; it revealed that the bias of TRV distribution...
