Abstract

New developments of vacuum interrupters based on radial magnetic field (RMF) contacts and axial magnetic field (AMF) contacts are presented. Important basis of the design of optimised contact constructions is the electromagnetic field calculation. In the first part of the paper the optimisations of AMF and RMF contact systems by means of the field simulation are presented. In the second part test results are shown which indicate the high current switching performance of both systems. The interrupting capability of both systems has been verified by the experiments up to 12 kV/63 kA and 36 kV/40 kA
