Abstract

An electric contact-breaker has sulphur hexafluoride gas for arc blow-out. Compression of the gas is obtained by the displacement of the moving contact. The contact-breaker has two moving parts (7, 32) to compress the gas. It also has a moving arc contact (12) connected to a main moving contact (14), and has a fixed arc contact (9) connected to a main fixed contact (6). It has a mechanism (35) to limit the travel of the moving arc contact (12) during arcing and to provide rapid separation after arcing. The mechanism (35) consists of a set of levers (22, 34) which controls opening of the contacts (12, 14, 9, 6) as well as pause and movement of the arc contact (12). The main fixed contact (6) is part of one (7) of the moving parts which compress the gas.
