    摘要: A multi-pole vacuum switch has an insulation assembly for each pole, which is composed of shell-like insulating elements. In addition to a space provided for receiving the vacuum interrupter, chambers are formed by wall sections, which are provided for receiving mechanical and electrical components of a pole unit. In particular, these electrical components are a loop-shaped, flexible strip conductor, a lever arrangement, contact springs and current transformers. Tensioning bolts which penetrate all the pole units connect the pole units to a pole block. The invention is suitable for use in vacuum power switches, in particular for low operating voltages.

    摘要: A vacuum switch including at least one vacuum switching tube and a pole operating unit which receives the vacuum switching tube at one of its ends. Each pole operating unit contains a lever arrangement for changing the direction of the operating movement provided by a drive device to the associated vacuum switching tube and a contact force spring. In addition, a connection contact surface for an external conductor is provided. The pole operating unit has a U-shaped carrier with elastically bendable legs. A connection device, also having a U-shaped cross-section, engages outside of the legs of the U-shaped carrier. A counter-bearing for the contact force spring is attached between the legs with when the legs of the carrier are bent. Alternatively, a cast metal connection device provided with cooling ribs can also be used.
