Abstract :
Application of vacuum interruption in distribution switchgear, especially in autoreclosers, which have uniquely high demands on vacuum fault interrupters, are discussed. The fast open-close-open sequence and its associated highly asymmetrical waveforms are some of the difficulties encountered. The authors present their solution to these problems in the form of an economical axial magnetic field interrupter that realizes current densities of up to 1.68 kA/cm2-the most efficient axial magnetic interrupter that is in production today. Actual design test data per ANSI C37.60 is shown
