Abstract

The subject-matter of the invention is construction of the mean voltage disconnector to be applied especially in mining electrical equipment. The mean voltage disconnector provided with the known contacts in the vacuum chambers, constructed in such a way that in each of three current paths of the disconnector, the immovable contact (1) and the movable contact (2) of the vacuum chamber (3) are connected in parallel with the immovable contact (4) and the movable contact (5) of the main current path of the disconnector. This connection is performed in such a way, that the immovable contact (1) of the vacuum chamber (3) is connected permanently and immovably with the immovable contact (4) of the disconnector, whereas themovable contact (5) provided with the cam (6) onits end is mounted rotationally on the end of the permanent joint (7), into which the rocker (9) having a shape of triangle is mounted also rotationally on the axis (8), and this triangle at one of its vertex (10) is connected by means of an articulated joint to the outer end of the movable contact (2) of the vacuum chamber (3), whereas at the second vertex of the rocker (9), close to the cam (6), the roll (11) tightened with the flat spring (12) is situated.
