Abstract
The invention discloses a three-position switch adopting a steering sensor. When a moving contact is driven by a rotating lead screw to be located at the middle position, the moving contact is not connected with the grounding end and the isolated closed end, and a switch is located in an isolated turned-on state. The lead screw is driven by a motor, a rotation sensor for sensing the rotating situation of the lead screw is arranged on the lead screw and is connected with an encoder controller, the encoder controller is connected with a numerical control device controlling rotation of the motor and outputs state signals of the moving contact located at a grounding position, an isolating position and a closed position to the numerical control device, and the numerical control device further controls forward rotation, reverse rotation and stopping of the motor according to the position signals of the moving contact and then controls a rotating state of the lead screw. The three-position switch adopting the steering sensor is reasonable in structure, convenient to operate, accurate in working position and good in working 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 of its different station relies on manually to be controlled, and accuracy is undesirable, influences the work effect.
Summary of the invention
The object of the present invention is to provide a kind of rational in infrastructure, the three-station of accurate, the easy to operate employing rotation direction sensor of working.
Technical solution of the present invention is:
A kind of three-station that adopts rotation direction sensor 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 isolates closing end; When moving contact is positioned at the left side under the drive that screw mandrel rotates, engage with earth terminal, switch is in ground state; When moving contact is positioned at the right side under the drive that screw mandrel rotates, engage with isolating closing end, switch is in isolates the discord state; When moving contact is positioned at the middle part under the drive that screw mandrel rotates, all do not engage with earth terminal and isolation closing end, switch is in the isolation open mode; Screw mandrel is by motor-driven, the rotation sensor of perception screw mandrel rotation situation is set at screw mandrel, rotation sensor is connected with the encoder controller, the encoder controller is connected with the numerical control device that the control motor rotates, coding controller is positioned at the status signal of earthing position, isolated location, make position to numerical control device output moving contact, further control the rotating of motor according to above-mentioned moving contact position signalling and stop by numerical control device, and then the rotary state of control screw mandrel.
The rotating of numerical control device control motor and the process that stops are: when initial, three-station is in earthing position, press " isolation " button of numerical control device, numerical control device control motor just changes, driving screw mandrel just changes, setting according to numerical control device makes moving contact arrive the isolation open position, and numerical control device sends the motor halt instruction, and motor stops operating; Press " ground connection button " on the numerical control device, the counter-rotating of numerical control device control motor drives the screw mandrel counter-rotating, makes moving contact arrive earthing position according to the setting of numerical control device, and numerical control device sends the motor halt instruction, and motor stops operating; Press " close push button " on the numerical control device, numerical control device control motor just changes, and driving screw mandrel just changes, and according to the setting of numerical control device moving contact is arrived and isolates closing end, and numerical control device sends the motor halt instruction, and motor stops operating.
