Break arcs are generated between pure silver electrical contacts in a DC high-voltage resistive circuit. The break arc is driven by the external magnetic field of a permanent magnet from horizontal direction of contacts. Electrical contacts are separated at constant opening speed at 75mm/s. The maximum supply voltage is 300V. The maximum circuit current when electrical contacts are closed is 20A. The maximum output power of the supply is limited to 6.3kW. The gap between the contacts and the magnet is defined as x. The gap is varied from 2.5mm to 10.0mm to change the magnetic flux density that affects to the break arc. The break arc is observed with a high-speed camera. The effect of the magnetic field on the arc duration was examined. As a result, break arcs are successfully extinguished by the transverse magnetic field when the gap x is 2.5mm. Increasing the gap x, the effect of the magnet to shorten to arc duration decreased. |
