Abstract
A vacuum switching unit of a vacuum circuit breaker has a vacuum interrupter, an insulating sleeve which surrounds the vacuum interrupter, extends tubularly about a longitudinal axis of the vacuum interrupter and is made of an insulating material. A plurality of capacitor electrodes are integrated into the insulating sleeve.
Claims14
A vacuum switching unit of a vacuum circuit breaker, the vacuum switching unit comprising:
- a vacuum switching tube having a longitudinal axis;
- an insulating sleeve formed of an insulating material, said insulating sleeve surrounding said vacuum switching tube in a tubular form around the longitudinal axis of said vacuum switching tube;
- a plurality of capacitor electrodes integrated into said insulating sleeve;
- and
- a coating disposed on at least one of a region of a surface of said vacuum switching tube that faces toward said insulating sleeve or at least one region of a surface of said insulating sleeve that faces toward said vacuum switching tube, said coating being configured to homogenize an electrical field between said insulating sleeve and said vacuum switching tube.
