High current interruption in vacuum circuit breakers [PDF]
Proceedings of 17th International Symposium on Discharges and Electrical Insulation in Vacuum, 1997 The aim of this project was to find a correlation between contact gap length and switching behavior of a vacuum circuit breaker. A large number of interruption experiments were executed in a vacuum chamber with butt type contacts made of Cu, CuCr 50/50 and AgWC. The currents to be interrupted varied from 2.5 to 32 kA.
