Lifting mechanism for solid insulation circuit breaker

Abstract

The invention discloses a lifting mechanism for a solid insulation circuit breaker. The lifting mechanism comprises a box body, wherein a mounting plate is fixedly mounted inside the box body; the outer surface of the mounting plate is fixedly connected with a fixed plate; a sliding chute is formed in the inner side of the fixed plate; the inner wall of the sliding chute is fixedly connected witha buffer spring; a sliding block is arranged inside the sliding chute, and the inner side of the sliding block is fixedly connected with a connecting plate; and the top of the connecting plate is fixedly connected with a plurality of insulation pull rod shafts. According to the lifting mechanism, an electric push rod, a first connecting rod, a fixed block, the connecting plate and the fixed plateare arranged, the fixed block is driven to move left and right through the movement of the electric push rod, the connecting plate is driven to move up and down along the sliding chute through the connecting adjustment of the first connecting rod, the insulation pull rod shafts are driven to move up and down together, and simultaneously adjustment is carried out. Therefore, the lifting mechanism is convenient and simple, the time is also saved, a supporting plate and an adjusting groove are formed, and the vertical movement of the connecting plate is more stable by using the relative sliding of an adjusting block and the adjusting groove.

Description

technical field [0001] The invention relates to the technical field of circuit breakers, in particular to a lifting mechanism for a solid insulation circuit breaker. Background technique [0002] The lifting operating mechanism of the high-voltage solid insulated circuit breaker is installed in the metal mechanism box and fixed with the main transmission mechanism. It is mainly used for closing and opening operations of the circuit breaker. Operate the three-phase insulating pull rod to connect the circuit, and the crank arms connected by the three-phase pull rod rotate independently. Because there are many transition links in the middle, it is difficult to ensure the synchronization of the three-phase actions, and it is impossible to adjust and cut off at the same time. Huge trouble. Contents of the invention [0003] The object of the present invention is to provide a lifting mechanism for a solid insulated circuit breaker, which solves the problem that its connection s...
