VALVE ARRESTER

摘要

VALVE ARRESTER A value arrester comprises a serial arrangement which includes at least one nonlinear resistor and spark gaps implemented as arcing horns which are housed in slit-type arc extinction chambers whose walls are made of an electric insulation material and form a single helical blade. The latter is arranged on a central cylindrical member and adapted to produce a single helical arc which i. formed from arcs struck during the arrester breakdown in the spark gaps, said arcs being joined together during their movement.
