Abstract
The utility model belongs to high voltage switch equipment part, in particular to a vacuum circuit breaker operating crankarm for driving a power output part of a vacuum circuit breaker control mechanism and a movable contact insulating pull rod of a vacuum extinction chamber. The vacuum circuit breaker operating crankarm comprises a rotating shaft part and an articulated hole, wherein the rotating shaft part is connected with a circuit breaker frame, and the articulated hole is connected with a control mechanism power output part; the vacuum circuit breaker operating crankarm further comprises a penetration-connected hole for penetration and connection with a joint bearing of an end part joint of the circuit breaker insulating pull rod; and the penetration-connection hole is a waist-shaped hole. In the vacuum circuit breaker operating crankarm the waist-shaped hole is matched with a penetration-connected pin to drive the insulating pull rod to move; and the penetration-connected pin can only transmit linear movement to the insulating pull rod due to the movement thereof in the range of the waist-shaped hole, thereby avoiding the swinging of the insulating pull rod, preventing the non-uniform stress of a movable contact during the switching on and off process, improving the moving reliability, avoiding damage of the extinction chamber and prolonging the service life of the circuit breaker.
Description
Technical field
This practicality relates to and belongs to the high voltage switchgear parts, specifically is that a kind of vacuum circuit-breaker that is used for transmission vacuum circuit-breaker operating mechanism power output and vacuum interrupter moving contact insulated tension pole is operated connecting lever.
Background technology
In vacuum circuit-breaker, be used for connecting the connecting lever of power output and moving contact insulated tension pole, the one end is installed on the circuit breaker cradle by rotating shaft, its other end and power output are hinged and drive its rotation by the power output, its stage casing generally also is connected by the joint screw rod that has oscillating bearing of circular connecting hole and insulated tension pole end, specifically be with being one with the endoporus cross-under of circular connecting hole on the connecting lever and oscillating bearing, realize interlock with a pivot pin.Though the rotation of connecting lever can move up and down to realize branch, to close a floodgate by the moving contact that oscillating bearing drives in insulated tension pole and the arc control device in this structure, but because connecting lever does is a kind of circular motion, therefore this upper and lower the moving of insulated tension pole is not moving up and down of a kind of straight line, but have the motion of swing, this just makes moving contact and arc control device unbalance stress, not only can reduce the contact reliability when closing a floodgate, also make arc control device be cast aside wound, scrap easily.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of motion state that can improve vacuum circuit-breaker is provided, reduce the unbalance stress in insulated tension pole and the moving contact motion process, improve the circuit breaker operational reliability and the vacuum circuit-breaker in useful life operation connecting lever.
Vacuum circuit-breaker operation connecting lever of the present utility model includes rotating shaft part that is connected with circuit breaker frame and the hinge hole that is connected with operating mechanism power output, also include a jack hole that is used for carrying out cross-under with the oscillating bearing of insulating pull rod for breaker end-fitting, described jack hole is a mounting hole, makes to be used for the pivot pin of cross-under oscillating bearing and jack hole and can to slide in mounting hole.
The utility model is owing to adopt mounting hole to cooperate with the cross-under pin, the action of drive insulated tension pole, because the cross-under pin can move in the mounting hole scope, thereby can only rectilinear motion be passed to insulated tension pole, and avoided the swing of insulated tension pole, prevented the unbalance stress in moving contact branch, the feed motion process, improved reliable in action, prevented to cast aside and hindered arc control device, prolonged circuit breaker useful life.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
