Study on impact of gap difference on plasma distribution of direct current vacuum circuit breaker with double-break

AIP Advances, 2023
During the fault current breaking process of a mechanical direct current vacuum circuit breaker (DC VCB) with double-break (DB), the mechanism’s dispersion can result in a gap difference between the two breaks. A DB DC VCB breaking experiment platform is
