Abstract

The invention discloses a three-position switch of gas-insulated switchgear using the numerical control technology. The three-position switch comprises a moving contact driven by a screw. The left and right sides of the moving contact are provided with a ground end and an isolated closed end respectively. When the moving contact is driven by the rotating screw to be located on the left, the moving contact is jointed with the ground end, and the switch is grounded; when the moving contact is driven by the rotating screw to be located on the right, the moving contact is jointed with the isolated closed end, and the switch is isolated and not jointed; when the moving contact is driven by the rotating screw to be located in the middle, the moving contact is not jointed with the ground end or the isolated closed end, and the switch is isolated and open; the screw is driven by a motor, a sensor for sensing the rotation conditions of the screw is disposed on the screw, the sensor is connected with a numerical control device which controls the motor to rotate, the numerical control device controls the motor to positively or reversely rotate and stop, and accordingly rotation conditions of the screw are controlled. The three-position switch is reasonable in structure, convenient to operate, precise in operating position and fine in operating performance.

Description

technical field [0001] The invention relates to a three-position switch of a gas insulated switchgear. Background technique [0002] In the existing gas insulated switchgear, the switching control of different stations is controlled manually, and the accuracy is not ideal, which affects the working effect. Contents of the invention [0003] The object of the present invention is to provide a three-position switch of a gas insulated switchgear using numerical control technology with reasonable structure, precise operation and convenient operation. [0004] Technical solution of the present invention is: [0005] A three-position switch of a gas insulated switchgear using numerical control technology, characterized in that: it includes a moving contact driven by a screw rod, and the left and right sides of the moving contact are respectively a grounding end and an isolation closing end; Driven by the rotation of the rod, when it is located on the left side, it is engaged w...
