ABSTRACT:
In an electric arc extinguishing apparatus, two electrodes are provided for initiation of the electric arc. Two conductors, each respectively connected to one of the electrodes, conduct the electric arc at high velocity under the influence of a magnetic field generated by the current of the arc itself. Movement of the arc along the conductors inserts a continuous electrical impedance in series with the arc. The two conductors are located in a winding channel formed in an arc resistant electrically insulating material such that the adjacent succeeding turns of the conductors are separated by the insulating walls of the channel. The winding channel emerges at one end into an annular channel containing an annular contact gap between the ends of both said conductors.
