Interrupting chamber for a gas insulated circuit breaker

摘要

The chamber has a contact arrangement held in a housing and arranged with two electric arc contacts (3, 4) that are adjustable along a symmetrical axis relative to each other. A flow space is guided at the electric arc contact (3). A compression device is guided with a fixed piston by a tubular contact, where the piston is formed in a ring shape. The piston is held at a wall of the flow space, where the wall and the piston are a part of a mounting unit (27) that is fastened at the housing.
