A compact vacuum interrupter has an insulator element, a moving contact connection, a fixed contact connection, a moving contact, and a fixed contact. The moving contact has a moving contact rod and a moving-contact contact element. The fixed contact has a fixed contact rod and a fixed-contact contact element. The moving contact is formed with a material that is mechanically stronger than a material of the fixed contact.

Compact vacuum interrupter

A vacuum interrupter has a housing with at least a first metal flange through which a first connection pin extends into the vacuum interrupter in a vacuum-tight manner to a first contact. The housing has at least one insulating-material housing region formed by a disc-like insulator. A second connection pin extends into the vacuum interrupter in a vacuum-tight manner to a second contact. The vacuum interrupter can be produced in a cost-effective manner with a compact construction. There is also described a switch pole for a switching device having a vacuum interrupter.

Vacuum interrupter and switch pole

A vacuum switch tube has a housing which has two insulating housing regions arranged and configured symmetrically in respect of a center plane. Each of the two insulating housings contains a plurality of insulating housing parts. Shielding elements extend into the interior of the vacuum switch tube and are arranged between neighboring insulating housing parts and between insulating housing parts and neighboring additional housing parts. The shielding elements have improved dielectric properties and a simultaneously material-saving structure. Accordingly, the geometrical dimensions of the shielding elements are determined in dependence on a connected voltage and possible critical field strength between neighboring shields.

Vacuum switch tube

A vacuum interrupter includes a housing having two insulating material areas disposed and constructed symmetrically with respect to a center plane. Each of the two insulating material housing areas includes a plurality of insulating material housing parts. The interrupter has a compact construction and high dielectric strength. The insulating material housing part of each insulating material housing area located farthest away from the center plane has a length that is greater than the length of the other insulating material housing parts.
