Abstract

PURPOSE:To have chemical formation on the surface even with large dia. of electrode by opening a vacuum interrupter at an opening speed higher than the rated opening speed. CONSTITUTION:Vibration current is made in the condition that a vertical magnetic field is applied by an external coil 4, and then arc is generated between electrodes of this vacuum interrupter 3. The electrode opening speed of the vacuum interrupter 3 at this time shall be higher than the rated electrode opening speed of the interrupter. That is, the gap between electrodes at the peak time of chemical formation current shall be greater than at the time of electrode opening with the rated opening speed. Thereby a vertical magnetic field is applied to the whole electrode surface, and the arc is dispersed uniformly over the whole electrode surface.
