DC vacuum circuit-breaker

2008 23rd International Symposium on Discharges and Electrical Insulation in Vacuum, 2008
The results of switching tests of a DC vacuum circuit-breaker designed for rated voltage 3.3 kV and rated current 3000A are presented. The circuit-breaker is intended for current interruption in the networks with fault currents up to 30 kA. To interrupt the direct current, the authors used a method of artificial current transition through zero in the ...
