ON-OFF MECHANISM FOR HIGH-VOLTAGE VACUUM SWITCH Russian patent published in 2005 - IPC

Abstract RU 2246776 C1

FIELD: electrical engineering; operating mechanisms of high-voltage vacuum switches.

SUBSTANCE: proposed ON-OFF mechanism has energy carrier, leverage for motion transfer from energy carrier to output shaft, and tripping mechanism with release lever. Leverage has lever arm, control rod, and dead center crossing kinematic link whose common articulated joint couples it through control rod to leverage arm. First and second members of kinematic link are hinged to output shaft lever and to release lever.

EFFECT: simplified design, enhanced reliability.
