Linkage mechanism of moving contact of combination switch, combination switch and power distribution system

Abstract

The invention discloses a linkage mechanism of a moving contact of a combination switch. A rotating shaft and the moving contact are arranged in the side, facing a body, of a rotating disc , the rotating shaft extends out in the axial direction of the rotating disc, a positioning groove is formed in the edge of the rotating disc, an installation groove, a fixed contact and a positioning protrusionare arranged in the side, facing the rotating disc, of the body, the rotating disc is rotationally installed on the body through the rotating shaft and the installation groove, and the positioning protrusion and the positioning groove are matched for positioning. A transmission column is arranged on the side, facing a transverse rod, of the rotating disc, and a transmission groove matched with the transmission column is formed in the transverse rod. According to the linkage mechanism of the moving contact of the combination switch, the structure is compact, on-off switching action of the moving contact and a fixed contact is achieved by driving the rotating disc to rotate and move axially, in the connecting process of the rotating disc and the body, transmission connection between the transverse rod and the rotating disc is released, on-off of the transverse rod and the rotating disc is not affected, multi-branch on-off separation control switching is achieved, and the intelligent networking difficulty of a power distribution network is reduced. The invention also provides the combination switch and the power distribution system.

Problems solved by technology

[0002] At present, in the low-voltage transmission and distribution network, such as single-phase load commutation on the user side, reactive power compensation cabinets on the transformer side and feeder cabinets, etc., the commutation switches, capacitor switching switches and branch circuit breakers used in centralized transmission and distribution and control distribution scenarios The switch can only independently control the corresponding load. In view of the actual working conditions, in the same power distribution scenario mentioned above, it is necessary to gather and use multiple identical or similar commutation switches, switching switches, and circuit breakers. As a result, they occupy a relatively large space. Second, in the process of intelligent networking of power transmission and distribution, each commutation switch, capacitor switching switch, or circuit breaker needs to occupy corresponding communication and control resources, which increases the number of intelligent transmission and distribution networks to a certain extent.
