摘要
A disconnect switch for metal-enclosed, compressed gas- insulated high- voltage switchgear, having two resistors for the suppression of high- frequency oscillations caused by the occurrence of a pre-flashover arc, each located along the longitudinal axis of and electrically connected to a moveable rod. Furthermore, a movable insulating tube covers the disconnect gap substantially before the resistors make or break contact with each other. Each resistor is comprised of several resistive elements which lie adjacent to one another between two contact plates at each end and are molded of hardened cast resin. Each element is comprised of a ceramic plate with baked-on strips of resistive material which have contacts on all four edges.
