Abstract

The invention discloses an isolating switch which comprises a driving rod, a frame, a fixed contact socket, a moveable contact cutter base, a connecting rod, a crank and an axle rod, wherein a moveable contact cutter is fixed on the moveable contact cutter base; the two ends of the moveable contact cutter base are in sliding connection with the frame; the moveable contact cutter base, the connecting rod, the crank and the axle rod are hinged in turn; a slider-crank mechanism is formed by the moveable contact cutter base, the connecting rod, the crank and the axle rod; the isolating switch further comprises a sheet spring; the axle rod is of cylinder shape; the sheet spring is located in the axle rod; and one end of the sheet spring is connected with an inner wall of the axle rod while the other end is connected with the driving rod. The quick switch-on / off of the isolating switch can be realized; the generation of arc during a brake separating process is reduced; the safety of operation and maintainers is ensured; and the isolating switch has a simple structure and is stable to work.

Description

technical field [0001] The invention belongs to the technical field of low-voltage electrical components. Background technique [0002] At present, the isolating switch can generally be divided into two types: knife switch type and rotary type. The rotary isolating switch includes a static contact socket and a rotatable moving contact knife. When opening and closing needs to be realized, the movable contact knife is rotated so that it is far away from and close to the static contact socket. Due to the generation of arc during the opening process, the temperature of the arc is very high, which is very harmful to the operation and maintenance personnel, and sometimes causes a phase-to-phase short circuit; Arc generation during opening. [0003] The structure of the existing isolating switch comprises a driving rod, a frame, a static contact socket, a moving knife base, a connecting rod, a crank and an axle rod, and the moving knife is fixed on the moving knife base, and the ...
