Abstract
The utility model relates to an indoor-side-mounting solid seal-type high-voltage vacuum circuit breaker, comprising a frame housing, wherein the frame housing backwards extends to form a support housing along a longitudinal direction. A, B and C three-phase vacuum arc-extinguishing-chamber terminals are successively spaced and fixed on the support housing. The support housing contains a main drive mechanism, wherein the main drive mechanism comprises a main connecting rod. One end of the main connecting rod is connected with a rotatable end of a main crank arm and the other end of the main connecting rod is connected with a mounting plate on an inside wall of the support housing by tensioned springs. Insulation pull rods of the A and B phase vacuum arc-extinguishing-chamber terminals are connected with the main connecting rod by a first crank arm and a second crank arm respectively. An insulation pull rod of the C-phase vacuum arc-extinguishing-chamber terminal is connected with the mounting plate by a third crank arm. An A, B and C three-phase main conductive loop adopts a structure of vertical fixed mounting and a main drive mechanism is separated from the frame housing. A structure in the frame housing is relatively compact, transmission efficiency is raised and breaker width is greatly reduced and the solid seal-type high-voltage vacuum circuit breaker is especially beneficial to realize miniaturization of a high-voltage switch cabinet.
Description
Technical field
The utility model relates to a kind of indoor side-mounted solid-sealed type high-voltage vacuum circuit breaker.
Background technology
Existing high-pressure vacuum breaker generally adopts the structure of vacuum interrupter cross direction profiles in the back of frame case, when operating mechanism drives the main shaft rotation, cross direction profiles and three transmission crank arm that are socketed on the main shaft are rotated simultaneously, and the insulated tension pole that drives in the three-phase electrode column of vacuum arc extinguishing chamber moves up and down.Because stored energy mechanism and operation transmission mechanism have increased the difficulty of product installation and maintenance greatly in a frame case, simultaneously, three transmission crank arm are laterally distributed, and the width of high-pressure vacuum breaker strengthens, and has increased taking up room of circuit breaker.
