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
The present invention relates to a kind of three-station of gas-insulated switchgear.
Background technology
Existing gas-insulated switchgear, the switch control rule of its different station relies on and manually controls, and accuracy is undesirable, affects working effect.
Summary of the invention
The object of the present invention is to provide a kind of rational in infrastructure, the three-station of the gas-insulated switchgear of the employing Numeric Control Technology working accurate, easy to operate.
Technical solution of the present invention is:
Adopt a three-station for the gas-insulated switchgear of Numeric Control Technology, it is characterized in that: comprise the moving contact that screw mandrel drives, the left and right sides of moving contact is respectively earth terminal and isolation closing end; When moving contact is positioned at left side under the drive that screw mandrel rotates, engage with earth terminal, switch is in ground state; When moving contact is positioned at right side under the drive that screw mandrel rotates, engage with isolation closing end, switch is in isolation discord state; When moving contact is positioned at middle part under the drive that screw mandrel rotates, with earth terminal with isolate closing end and all do not engage, switch is in isolation open mode; Screw mandrel has motor to drive, and screw mandrel arranges the transducer of perception screw mandrel rotation situation, and transducer is connected with the numerical control device controlling electric machine rotation, is controlled rotating and the stopping of motor, and then control the rotary state of screw mandrel by numerical control device.
Numerical control device controls the rotating of motor and the process of stopping is: time initial, three-station is in earthing position, press " isolation " button of numerical control device, numerical control device controls motor and rotates forward, drive screw mandrel rotates forward, make moving contact arrive isolation open position according to the setting of numerical control device, numerical control device sends motor halt instruction, motor stalls; Press " the ground connection button " on numerical control device, numerical control device controls motor reversal, drives screw mandrel reversion, and make moving contact arrive earthing position according to the setting of numerical control device, numerical control device sends motor halt instruction, motor stalls; By " close push button " on numerical control device, numerical control device controls motor and rotates forward, and drives screw mandrel to rotate forward, and make moving contact arrive isolation closing end according to the setting of numerical control device, numerical control device sends motor halt instruction, motor stalls.
The present invention is rational in infrastructure, easy to operate, and service position is accurate, favorable working performance.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is the structural representation of one embodiment of the invention.
