The Influence of Axial Magnetic Field Distribution on High-Current Vacuum Arc

The Axial Magnetic Field (AMF) applied to the arc vacuum column in the vacuum tube can make the vacuum arc keeping in diffusion state, provided that the short circuit current to be interrupt is within a critical value. In the results, the breaking ability of Vacuum Interrupters can be highly improved with the help of the AMF. The experimental study has proved that the AMF should be sufficient strong and have optimum distribution, in order to improve the breaking capacity of vacuum circuit breaker. This paper presents a novel axial magnetic contact with the concave axial magnetic field distribution and its 3-d simulation.
