Abstract

Multipole load break switch for high nominal intensity comprising, for each pole, an insulating bushing enclosing a vacuum bulb (14) and two conductive blades (7, 8) for the flow of the permanent current, the bushings being integral with a common metallic supporting profile (4) placed at earth potential and shrouding a common shaft for operating the vacuum bulbs, actuated by a mechanism contained in a box integral with the profile, the elements for connection of the bushings of the poles being arranged so that, when the profile pivots, the current is switched from the blades (7, 8) to the vacuum bulbs (14). The invention applies to the construction of medium voltage cells and installations with high nominal intensity. <IMAGE>
