Abstract

A circuit breaker, a valve assembly and an operating method thereof are provided. The circuit breaker comprises a compression volume surrounding at least a portion of a space between first and second electric contacts, and a low-pressure volume, filled with insulating gas, disposed adjacent to the compression volume. The circuit breaker further comprises a valve assembly interconnecting the compression volume and the low-pressure volume, and configured to allow threshold-based flow of the insulating gas. The valve assembly comprises a valve body. The valve assembly also comprises a first valve plate movably mounted in the valve body and a second valve plate movably seated on the first valve plate. The valve assembly further comprises a plurality of Belleville springs radially arranged in the valve body, and configured to constrain the movement of the first valve plate up to the third position of the second valve plate in the valve body.
