VACUUM SWITCH Russian patent published in 1999 - IPC

FIELD: electrical engineering. SUBSTANCE: device has at least one horizontal vacuum arc- quenching chamber, which is mounted in tank filled with dielectric material. Stationary terminal of arc-quenching chamber is connected to first terminal of switch. Mobile terminal of arc-quenching chamber has flexible connection to another terminal and through contact-loading mechanism to chamber control unit. Inputs are equipped with current-pickup cantilevers which are connected to each other rigidly by means of insulators. Vacuum arc-quenching chamber is mounted at inputs of switch. Stationary terminal of chamber is rigidly attached to current-pickup cantilever of one terminal. Mobile terminal is connected through flexible tie to current-pickup cantilever of another terminal on which chamber control unit is rigidly mounted. EFFECT: decreased size, simplified design, decreased bending loads in vacuum arc-quenching chamber. 4 cl, 1 dwg
