First Claim
Patent Images
1. A medium voltage circuit breaker for a high pressure subsea environment, comprising:
- three switching elements, so as to provide an electrical three-phase arrangement with one switching element per phase; and
three drives, one drive for each switching element, the three drives being mounted inside a common base compartment,wherein each of the three switching elements is arranged in a separate pole housing, to form three pole housings, the three pole housings being mounted to the common base compartment,wherein the three pole housings and the common base compartment form a pressure tight compartment comprising a single volume that is bounded by the three pole housings and the common base compartment, andwherein each switching element has internal contacts on either side thereof, such that the internal contacts of each switching element are exposed to the single volume.

Abstract
A medium voltage circuit breaker in a high pressure subsea environment includes: a vacuum circuit breaker; and a drive in a pressure tight housing. For an electrical three-phase arrangement, one vacuum circuit breaker per phase is arranged in a separate pole housing each, and the resulting three pole housings are mounted to a common base compartment, in which three drives for the three vacuum circuit breakers are arranged. The three pole housings and the common base compartment are attached such that they commonly form a pressure tight compartment.
