Lifting device of side-mounted circuit breaker

Abstract

The invention relates to the technical field of power distribution switch control equipment manufacturing and in particular discloses a lifting device of a side-mounted circuit breaker. The lifting device comprises a screw rod, a first sliding block, a second sliding block, a first connecting rod, a second connecting rod, a first linear guide track and a second linear guide track which are all positioned on a same side of a bottom disc, wherein the screw rod is positioned on the right disc surface of the bottom disc; outer threads are formed in the screw rod; the screw rod is sleeved by the first sliding block and the second sliding block; inner threads are formed in the first sliding block and the second sliding block; a driving mechanism is positioned at one end of the screw rod; one endof the first connecting rod is connected with the first sliding block; the other end of the first connecting rod is connected with the bottom of the circuit breaker; one end of the second connectingrod is connected with the second sliding block; the other end of the second connecting rod is connected with the bottom of the circuit breaker; one end of each of the first linear guide track and thesecond linear guide track is fixed on the right disc surface of the bottom disc; the other ends of the first linear guide track and the second linear guide track are connected with the bottom of the circuit breaker. By adopting the lifting device of the side-mounted circuit breaker, switching of working positions and testing positions of the circuit breaker can be achieved in an up and down movement mode.

Description

technical field [0001] The invention relates to the technical field of manufacturing power distribution switch control equipment, in particular to a lifting device for a side-mounted circuit breaker. Background technique [0002] The side-mounted arrangement of the switchgear can achieve the same phase sequence of the circuit breaker and the main busbar, forming a simple T-shaped structure of the primary circuit, which has many advantages such as saving space and reducing auxiliary supports, and is an effective way to realize the miniaturization of the switchgear. After the side-mounted arrangement of the circuit breaker, the conversion between the test position and the working position cannot continue to be realized by the traditional forward and backward movement, otherwise the consistency of the phase sequence cannot be guaranteed. [0003] Therefore, how to satisfy the conversion between the test position and the working position of the side-mounted arrangement of the ...
