EXTINCTION OF ARCING IN CONTACT LINE SECTION INSULATORS

LICHTBOGENLOSCHUNG AN FAHRLEITUNGSSTRECKENTRENNERN

To extinguish an electric arc rapidly, it must be extended quickly, and at the same time, the thermoionisation must be eliminated by cooling and by deionising gas. This result may be achieved by horned circuit-breakers, and by lateral strips of synthetic material, which discharge a deionising gas when heated by the electric arc. By means of these devices, arcs can be existinguished efficiently up to 400 A. The arc current may be raised to 600 A by additional circuit-breaking electrodes.
