V-t characteristics of vacuum interrupter after large current interruption
24th ISDEIV 2010, 2010Because of the contact material's evaporation and ejection of some metal particles out of the contact gap during the flow of the vacuum arc, the contact surface may exhibit some erosion after each operation of vacuum circuit breakers. In this study, the insulation properties were investigated for vacuum interrupters with the rated voltage about 10 kV ...

The intrinsic limits of vacuum interruption
2008 23rd International Symposium on Discharges and Electrical Insulation in Vacuum, 2008The role of particles, metal vapour, gas and molten electrode surfaces are discussed in relation to post arc failure of vacuum circuit breakers. A new full PIC-Monte-Carlo simulation model is descried and the numerous physical mechanisms which are included in it are illustrated.

Contact Materials for Vacuum Interrupters
IEEE Transactions on Parts, Hybrids, and Packaging, 1974A comprehensive review of the large number of contact materials that have been proposed for vacuum interrupter applications is presented. These contact materials are classified into four major groupings: 1) pure metals, 2) alloys, 3) mixtures of refractory materials and good conductors, and 4) mixtures of semirefractory materials and good conductors ...

Vacuum Interruption-A Review of the Vacuum Arc and Contact Functions
IEEE Transactions on Industry Applications, 1972The growing use of vacuum interruption devices by the power and control industry in the last decade introduces these devices to many people for whom the area of vacuum interruption is somewhat new. It is felt that a review of the subject of vacuum interruption from a scientific and technological viewpoint, is needed.
