VACUUM CIRCUIT BREAKER UNDER HIGH PRESSURE

摘要

A vacuum circuit breaker for the use in high pressure environments, has at least one vacuum interrupter with at least one moving contact and at least one fixed contact inside the vacuum interrupter, and external contact points at the vacuum interrupter. The vacuum circuit breaker can be used under the high-pressure environmental conditions through the use of at least one vacuum interrupter arranged in a pressure tight container, wherein the electrical contacting is realized via a high voltage bushings through the container wall, and the pressure tight container is at least partially filled with insulating oil.
