Abstract: The objective of this paper is to compare the temperature-rise performance of 4 kinds of AMF contacts designs of 126 kV vacuum circuit breakers (VCBs). The 4 AMF contacts designs are 2/3 ...

Abstract: The dielectric recovery strength (DRS) of vacuum circuit breaker (VCB) interrupter is closely related to the travel characteristic of contact, which determines the overvoltage caused by ...
