Abstract
The utility model provides a withdrawable switchgear with electric operation module, which comprises a cabinet body (1) and a withdrawable handcart (3), wherein the withdrawable handcart (3) comprises a main body (4) of the handcart and a chassis vehicle (5) for driving, supporting and fixing the main body of the handcart. The chassis vehicle (5) comprises a frame and an electric operation module (6) installed on the frame. The electric operation module (6) is connected with a feed screw nut propulsive mechanism, and pushing in or out operations of the handcart in the switchgear can be realized, thereby realizing contact or separation between a movable contact on the handcart and a static contact in a contact box of the switchgear. The switchgear realizes moving unmanned operations of the handcart between a testing position in the cabinet and a working position, the operation is simple, the use is convenient and safe, the withdrawable switchgear completely accords with demands of a modern power system to the switchgear on the aspects of automation, intelligence and high reliability and completely accords with demands of a converting station for satisfying unmanned on duty and automatic control.
Description
Technical field
The utility model relates to a kind of switch cubicle, and is special relevant with a kind of withdraw-type switch cabinet.
Background technology
At present, the withdraw-type switch cabinet that the power transmission and distribution industry is used generally is made up of cabinet and removable handcart, but the withdraw-type handcart comprise the handcart main part and be used to drive, support, the fixing chassis car of handcart main body.Handcart moves between test position and the service position in switch cubicle and realizes by manual operation, be armrest shake special-purpose cranking bar clockwise or the leading screw that rotates counterclockwise on the car of handcart chassis promote the handcart motion, handcart is advanced or withdraw from by changing the crank direction of rotation, thereby realize the contact of the fixed contact in moving contact and the switch cabinet contact box on the handcart or separate.Its shortcoming is that operating personnel's execute-in-place before cabinet must be arranged, and can not satisfy the intelligentized requirement of unattended operation and switch cubicle.
The utility model content
The purpose of this utility model is to provide a kind of can realize handcart moving freely between test position and the service position in switch cubicle automatically, satisfies the withdraw-type switch cabinet that unattended operation and automation control requires.
The technical solution of the utility model is: a kind of withdraw-type switch cabinet with electronic operational module, but comprise cabinet and withdraw-type handcart.Handcart comprises handcart main body and chassis car, and the chassis frame is provided with the electric operating module.The electric operating module is made up of motor, worm screw, arrangement of clutch, the gear width of cloth and location locking mechanism.Motor is by worm gear and worm engaging, worm screw cooperates interlock by arrangement of clutch with driving gear, arrangement of clutch is made up of fixed block and separable, wherein fixed block is fixedlyed connected with worm screw, fixedly connected with driving gear for separable, be connected with positioning and locking device again, and can endwisely slip along axle, driving gear and driven gear engagement, driven gear and the engagement of feed screw nut propulsive mechanism.
The utility model switch cubicle has adopted electric operating module and feed screw nut propulsive mechanism to connect, realize the branch that closes of arrangement of clutch by the position that changes positioning and locking device, the combination that makes feed screw nut propulsive mechanism and motor with separate, realize electric operating and manually-operated conversion.Handcart pushes or withdraws between test position and service position can realize unmanned operation, can realize mutual switching electronic, manual operation chassis car simultaneously.Simple to operate, easy to use, safe, but both local operations, but remote control operation again meets the requirement of modern power network to the automation of switch cubicle, intellectuality, high reliability fully, meets the requirement that transformer station satisfies unattended operation and automation control fully.
