Abstract
FIELD: electrical engineering, in particular, high-voltage electric apparatuses, it is intended for switching and protection of load electric circuits. SUBSTANCE: the switch has a vacuum arc chute with break gap 16, contact spring 15, switching axle 1 with lever 2, which is connected to break gap 16 by means a free trip mechanism. The switch provides for disconnection of the power mechanism from the contact system for the period of disconnection operation, thus the speed of contacts break does not depend on the kinematics of the power mechanism and is determined by the spring characteristics only. EFFECT: enhanced reliability. 1 dwg
