Gas-insulated single-pole switching device has load breaker and earthing switches within gas-tight housing having cylindrical section fitted with at least one concave end wall

摘要

The switching device (1) has an electrically-conductive gas-tight housing (3) filled with an insulation gas having a cylindrical section (6) fitted with 2 end walls (4,5), containing load breaker and earthing switches (14,25), with insulation of the housing relative to the switches and the electrical connections (2,10,13,15,16). The load breaker switch has a switch mechanism with a linear displacement in the longitudinal direction of the housing cylindrical section, at least one end wall of the housing bent outwards with a concave curvature.
