Abstract
The invention discloses a breaker insulation pull bar. The breaker insulation pull bar comprises an umbrella skirt. The two ends of the umbrella skirt are respectively provided with a connection pull bar I and a connection pull bar II. At least one from the connection pull bar I and the connection pull bar II is connected with the end portion of the umbrella skirt through an elastic structure. According to the breaker insulation pull bar, the elastic connection structure is adopted for buffering the impact force of a contact during switching-on and switching-off so that the bounce of the contact can be effectively reduced or even eliminated, and the connecting and disconnecting performance of a breaker can be improved.
Description
Technical field
The present invention relates to primary cut-out accessory technical field, be specifically related to a kind of insulating pull rod for breaker.
Background technology
The spring of contact during circuit-breaker switching on-off, has a strong impact on the break performance of circuit breaker, and the factor that affects circuit-breaker switching on-off spring mainly contains: the quality of moving component, speed, the rigidity of contact pressure and insulated tension pole.The insulated tension pole integral body of using is at present rigidity, at moment and the rigidly connected contact of insulated tension pole of divide-shut brake, can produce spring by a relatively large margin, has a strong impact on the break performance of circuit breaker.
Summary of the invention
The object of the invention is for above-mentioned existing issue, a kind of insulating pull rod for breaker of the spring producing can reduce or eliminate contact of breaker divide-shut brake time is provided.
The technical solution used in the present invention is: a kind of insulating pull rod for breaker, comprise full skirt, the two ends of described full skirt are respectively equipped with cylinder lever connecting rod I and cylinder lever connecting rod II, and described cylinder lever connecting rod I is with in cylinder lever connecting rod II, at least one adopts elastic construction to be connected with the end of full skirt.After adopting elastic construction to connect, the impulsive force in the time of can be to divide-shut brake cushions, and reduces even to eliminate spring.
Described full skirt one end is fixedly connected with cylinder lever connecting rod I, the other end of full skirt is provided with connecting hole, described cylinder lever connecting rod II end is slidably mounted in connecting hole, between the bottom of connecting hole and the end of cylinder lever connecting rod II, be provided with dish spring, the opening part of connecting hole is provided with for by the spacing fixture in connecting hole of cylinder lever connecting rod II, and the end of cylinder lever connecting rod II is pressed in dish spring the bottom of connecting hole.
The diameter of the part of described cylinder lever connecting rod II in connecting hole is greater than the part in connecting hole outside, in the middle of described fixture, be provided with the through hole partly passing for cylinder lever connecting rod II path, the opening part inside of connecting hole is provided with internal thread, the outer wall of fixture is provided with the external screw thread with the screw-internal thread fit of connecting hole, and fixture is enclosed within cylinder lever connecting rod II and by screw thread, is fixed on the peristome of connecting hole.
The invention has the beneficial effects as follows: insulating pull rod for breaker of the present invention, while adopting elastic connection structure to cushion divide-shut brake, the impulsive force of contact, can effectively reduce the spring of even eliminating contact, improves the break performance of circuit breaker.
