Description
Technical field
The utility model belongs to middle and high voltage switching station, relates to a kind of Vacuum Breaker Contact Transmission Structure that is used for vacuum circuit-breaker.
Background technology
The moving contact drive mechanism of vacuum circuit-breaker has generally comprised one and has thoroughly done away with the edge pull bar, and the front end of insulated tension pole is the moving contact link that is connected with moving contact in the vacuum interrupter, and the rear end of drawing of insulating is the mechanism's link that is connected with operating mechanism.In the existing drive mechanism, mechanism's link of insulated tension pole is generally the metalwork that fixedly is inlaid in the insulating body, the moving contact link then be one can the certain limit in insulating body in flexible metalwork.The defect map of this structure is present: 1, because insulating body and moving contact are not to be rigidly connected, so the total quality of moving contact is less, and moving contact rebounds easily when closing a floodgate like this, has reduced reliability of operation; 2, since with the kinematic coupling portion of insulated tension pole moving contact link as main governing loop, and whole device inside is often stretched in the installation site of this part in vacuum circuit-breaker, thereby has brought very big inconvenience to its installation and adjusting.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of simple in structure, installation and Vacuum Breaker Contact Transmission Structure easy to adjust, that reliable in action is high are provided.
Vacuum Breaker Contact Transmission Structure of the present utility model includes respectively the insulated tension pole that is connected with operating mechanism by moving contact link and mechanism link and moving contact; The moving contact link of described insulated tension pole is a fixed connecting rod, and an end of fixed connecting rod fixedly is inlaid in the insulating body of insulated tension pole, and the other end of fixed connecting rod is connected by the moving contact of screw thread with vacuum interrupter one end; Mechanism's link of described insulated tension pole includes an inserts that has cylindrical cavity that is embedded in the insulating body, is inserted with a movable connecting rod in the inner chamber of inserts; The leading portion of movable connecting rod is arranged in the inserts inner chamber, and the stage casing of movable connecting rod has the bigger crossette of diameter, and this crossette is blocked in the inner chamber of inserts by a guide vane end stop, is provided with several dish springs between the bottom of crossette and inserts inner chamber; Guide vane end stop is connected the opening part of inserts inner chamber by external screw thread, and the through hole that the back segment of movable connecting rod passes the guide vane end stop center stretches out inner chamber, and is connected with operating mechanism.Have the transducer installing hole on the rear end face of described movable connecting rod, be used for sensor installation, test with divide-shut brake mechanical property to circuit breaker.
The utility model is simple and reliable for structure; Because insulating body and the moving contact of insulated tension pole is rigidly connected in the circuit breaker running, thereby increased the total quality of moving contact part, the instability of having brought because of the bounce-back of moving contact when having reduced combined floodgate; Owing to can realize flexibly connecting and adjusting by mechanism's link of insulated tension pole, its position has made things convenient for to be installed and regulates simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of insulated tension pole.
Embodiment
As shown in the figure, in this structure, insulating body 11 front ends of insulated tension pole 1 fixedly are embedded with a fixed connecting rod 12, and the front end of fixed connecting rod is connected with moving contact 2 in the vacuum interrupter by screw thread.The insulating body rear end of insulated tension pole is fixed with the inserts 13 that has inner chamber, there is the leading portion of a movable connecting rod 14 to be inserted in the inner chamber of inserts, inserts open rearward end place is by the guide vane end stop 15 that has been threaded, the guide vane end stop front end is blocked in crossette 141 places in movable connecting rod stage casing, carries out spacing to the axial location of movable connecting rod.Be provided with a plurality of dish springs 16 between the bottom surface of crossette 141 and inserts inner chamber,, when separating brake, improve opening velocity simultaneously to guarantee having certain contact pressure between dynamic and static contact when the breaker closing.The through hole 151 that movable connecting rod back segment after the crossette passes the guide vane end stop center is connected with operating mechanism.Also have a transducer installing hole 142 on the rear end face of movable connecting rod, be used for installing the transducer that the circuit-breaker switching on-off mechanical property is tested.
