ABSTRACT:
In a metal encapsulated, pressurized gas insulated high voltage disconnect switch operating at voltages above 245 kV, weak arcs drawn during the switching operation are prevented from wandering off, so that they cannot commutate to the encapsulation and produce an arc to ground, by an electric field in the switching gap controlled by moving a field electrode jointly with the switching rod, with the motion cycles of the switching rod and the field electrode controlled during the closing and opening process in a forced manner by a lever linkage provided with steering rods for the switching rod and the field electrode.
