MECHANISM FOR MANUAL DISCONNECTION OF DRIVES OF HIGH-VOLTAGE VACUUM CIRCUIT BREAKER Russian patent published in 2020 - IPC H01H33/00 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, namely to designs of high-voltage vacuum circuit breakers with possibility of their manual disconnection. Design of mechanism for manual disconnection of high-voltage vacuum circuit breaker additionally comprises manual disconnection shaft intended for transmission and distribution between forces mechanism parts aimed at disconnection of high-voltage vacuum circuit breaker in manual mode, manual disconnection button is connected to the manual disconnection shaft by means of the pull-out button of the manual disconnection, between the magnetic conductors and the anchors installed in them there are symmetrically installed breaks made in the form of levers with eccentrics at the ends, which are installed by their cylindrical surfaces in the corresponding slots of the magnetic conductors, and flat surfaces adjoin lower surface of anchors, and, besides, to opposite ends of releases are attached tractors connected to brackets, fixed on shaft of manual disconnection, holes in tie-rods or in brackets of different shape, for example round, elongated or oval, and have different length.

EFFECT: higher reliability of mechanism for manual disconnection of drives without making fundamental changes to existing design of high-voltage vacuum switches, and also possibility of creation in the same dimensions of high-voltage vacuum switches having more powerful drives designed for higher currents.
