LOADBREAK ARC SNUFFING DEVICE

摘要

LOADBREAK ARC SNUFFING DEVICE An arc snuffing device for use on high voltage circuits during loadbreaking operations, the device including an arc quenching tube biased for movement over an electrical contact and an arc quenching member during a load breaking operation to confine the arc produced on loadbreak to the space between the arc quenching tube and the arc quenching member, the arc quenching tube further defining the direction of flow of the arc quenching gases produced by the arc to produce a partial vacuum in the space where the arc is confined and induce an air blast into the space to quench the arc, the arc quenching tube being automatically reloaded on reclosing of the electrical contacts.
