Abstract
A three-pole switch arrangement has for each pole a pole housing, onto which collar-shaped extensions, protruding on the underside, are formed. Provided in the extensions are screw holes, the graduation of which corresponds to the screw coupling, by which the mechanism housing has been screwed to the pole housing. The outer switch poles are oriented outwardly by one graduation and are fastened to the frame by means of screws. Counter to this inclined position, the mechanism housing, rotated by one graduation, is screwed onto the pole housing. It is consequently possible to use the same parts for all three switch poles, and also to transport the switch arrangement pole-by-pole.
Claims8
A three-pole, gas insulated switch arrangement comprising an inner pole and outer poles, a metallic encapsulating means supported on a frame, said encapsulation means comprising for each pole an essentially cylindrical pole housing connected in gas-tight manner at one end to a cover and at the other end to a mechanism housing for a switch mechanism, interrupter elements arranged in the respective pole housings and supported on the encapsulation means via insulators, the pole housings being arranged adjacent one another with mutually parallel longitudinal axes and each being connected to two bushings, the bushings having longitudinal axes which lie in an axial plane of the respective pole housing, the axial plane of the inner pole extending essentially vertically and the axial planes of the outer poles extending outwardly at an incline with respect to the inner pole, wherein the interrupter elements are supported on the pole housings, the respective cover and the respective mechanism housing are fastened to the respective pole housing each by means of a circular arrangement of evenly distributed screw couplings, and the pole housings are fastened to the frame by a further circular arrangement of screw couplings having the same circumferential graduations therebetween as the screw couplings which fasten the mechanism housings to the pole housings, the outer poles having axial planes inclined by at least one graduation of the screw couplings relative to the inner pole.
