Abstract RU 2828462 C2

FIELD: electricity.

SUBSTANCE: invention relates to electric circuit switching units intended for electric current interruption. Switching unit (2) for switching electric current comprises separable fixed (4) and movable (8) electric contacts and mechanism (10) capable of switching contacts between closed state and open state. Switching mechanism comprises switching shaft (20) connected to movable electrical contact (8), disengaging hook (40) mounted to rotate on the fixed support of the mechanism, and having a hole in which stop (48) is located, and lever system (22) connecting switching shaft (20) with release hook. Lever system comprises articulated clutch which is rotatably coupled with release hook (40) and which comprises main bearing surface (85), which rests on stop (48) when switching mechanism is in closed state. Stop (48) is made with possibility of elastic deformation when switching mechanism changes from open state to closed state, and clutch acts on stop in order to damp clutch impact against stop.

EFFECT: increased number of opening and closing cycles allowed during unit service life.
