Abstract (en)
Vacuum circuit breaker assembly with a housing (11, 12, 13) in which a vacuum circuit breaker (15) is accommodated. The housing (11, 12, 13) is fluid tight and arranged to maintain a pressure inside the housing (11, 12, 13) at a predetermined level which is independent of a pressure outside the housing (11, 12, 13).The vacuum circuit breaker assembly (10) may be used in a switchgear assembly with an external housing (25, 35). The external housing (25, 35) has an inner space (31) sealed from an external environment (30), in which the inner space (31) is filled with a substantially non-compressible material such that, in operation, the pressure in the inner space (31) is substantially equal to the pressure of the external environment (30). The switchgear assembly may be advantageously used in sub sea or deep sea environments.
