  • Magnetic extinction of arcs in switches
    Patent number: 4421963
    Abstract: The arc formed during circuit-breaking is lengthened to extinction. In order to achieve this, the magnetic flux density, the arc current intensity, and the gas pressure, adjacent the cathodic spot 11, are chosen to be such that the cathodic spot 11 is displaced contrary to the Lorentz force. The necessary magnetic field is preferably provided by a magnet 6 whose stray magnetic field has flux lines which form an arched tunnel extending along the cathode 1.
