Abstract:

An arc interrupter for heavy surge currents in power systems is provided in which a self-biasing, spring helix conductor is fixed between two frangible andor fusible elements which are in turn integrally fastened to the edges of respective eddy-current rings canted to effect a horn gap for magnetic blow-out of any ensuing arc in the area of the helix. The helix generates magnetic forces in addition to its spring force to break the fusible andor frangible elements in response to predetermined surge currents and will then drop out of the gap between the eddy-current rings by gravity action. The circuit is thus broken and any ensuing arc is extinguished. Author
