초록
The increasing application of Vacuum Circuit-Breakers (VCB) on utility and industrial systems has prompted and detailed investigation of vacuum switching surge mechanisms and protections. This paper arranges arc-extinguishing principles of magnetic field in vacuum in order to disperse rapidly arc generated from vacuum contacts on switching VCR and plans establishment of protection means to protect high-voltage motor against surge voltage magnitude and transient voltage rate of rise
