Abstract
The utility model discloses a switching -on holding device for circuit breaker has the output turning arm and locates the breaking brake semi axis of output turning arm one side to and separating brake buckle and the sincere son of separating brake, the sincere son of separating brake buckle and separating brake is the components of a whole that can function independently, and the sincere son of separating brake concatenates together through round pin axle and separating brake buckle, at separating brake and combined floodgate in -process, separating brake buckle rigid, and the sincere son of separating brake can round the round pin axle rotates for the separating brake buckle. It is equipped with the torsional spring to sell epaxial still cover, the one end of torsional spring with the separating brake buckle is connected, and the other end is connected with the sincere son of separating brake. The utility model discloses an advantage: with separating brake buckle and separating brake pallet separately, make the combined floodgate in -process, breaking brake semi axis is motionless, is in the holding position all the time, combined floodgate in -process separating brake pallet anticlockwise rotation and the separating brake buckle is motionless. Having reduced the torsion of breaking brake semi axis reduction torsion spring greatly, having reduced the tripping force, reduced separating brake coil power and electric current, convenient operation has improved the reliability of quadratic element device.
Description
Technical field
The utility model relates to circuit breaker interlocking device technical field, is specifically related to a kind of breaker closing holding device.
Background technology
The separating brake pallet of existing design and separating brake buckle are one, with reference to shown in Fig. 1, in making process, separating brake buckle 5 rotates counterclockwise, the separating brake buckle when position that closes a floodgate returns clockwise under reduction torsion spring 7 twisting force, separating brake semiaxis 8 resets at reduction torsion spring clockwise under influence simultaneously, for ensureing to close a floodgate reliably, separating brake semiaxis reset torsion spring torque force is sufficiently large, being enough to resets at combined floodgate roller and buckle Contact puts in place, Cai Nengshi mechanism keeps closing position, so separating brake semiaxis tripping force is very large, manual brake separating difficulty, switching winding power, electric current is also excessive, cause fluctuation of service and secondary failure.
Utility model content
The purpose of this utility model is to make up the deficiencies in the prior art, provides a kind of breaker closing holding device improving secondary component reliability.
In order to reach the purpose of this utility model, technical scheme is as follows:
A kind of breaker closing holding device, there is output toggle arm and be located at the separating brake semiaxis of described output toggle arm side, it is characterized in that, also comprise separating brake buckle and the sincere son of separating brake, described separating brake buckle and the sincere son of separating brake are splits, and the sincere son of separating brake is serially connected, in separating brake and making process by bearing pin and separating brake buckle, separating brake buckle maintains static, and the sincere son of separating brake can rotate relative to separating brake buckle around described bearing pin.
Further, described bearing pin is also arranged with torsion spring, one end of described torsion spring is connected with described separating brake buckle, the other end and the sincere sub-connection of separating brake.
The beneficial effect that the utility model has:
Separating brake buckle and separating brake pallet are separated, separating brake pallet is connected with separating brake buckle with torsion spring by bearing pin, makes in making process, and separating brake semiaxis is motionless, is in holding position all the time, and in making process, separating brake pallet rotates counterclockwise and separating brake buckle is motionless.Substantially reduce the torsion of separating brake semiaxis reduction torsion spring, reduce tripping force, reduce switching winding power and electric current, easy to operate, improve the reliability of Quadratic Finite Element device.

Structural representation when Fig. 2 is "on" position.
Embodiment
Below in conjunction with embodiment, the utility model is further described, but protection range of the present utility model is not only confined to embodiment.
Shown in composition graphs 1, Fig. 2, a kind of breaker closing holding device, there is output toggle arm 2 and be located at the separating brake semiaxis 8 of described output toggle arm 2 side, and also comprise separating brake buckle 5 and separating brake sincere sub 4, separating brake buckle 5 and separating brake sincere sub 4 are splits, and separating brake sincere sub 4 is serially connected, in separating brake and making process by bearing pin 6 and separating brake buckle 5, separating brake buckle 5 maintains static, and separating brake sincere sub 4 can rotate relative to separating brake buckle 5 around described bearing pin 6.Bearing pin 6 is also arranged with torsion spring 1, and one end of torsion spring 1 is connected with separating brake buckle 5, and the other end is connected with separating brake sincere sub 4.
In making process, output toggle arm 2 rotates, and suppresses separating brake sincere sub 4 by roller 3, and separating brake sincere sub 4 is rotated, and in making process, separating brake semiaxis 8 is motionless, is in holding position all the time, and in making process, separating brake pallet 4 rotates counterclockwise and separating brake buckle 5 is motionless.
Last it is noted that above embodiment only in order to illustrate the utility model and and technical scheme described by unrestricted the utility model, therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment, but, those of ordinary skill in the art is to be understood that, still can modify to the utility model or equivalent replacement, and all do not depart from technical scheme and the improvement thereof of spirit and scope of the present utility model, it all should be encompassed in right of the present utility model.
