Abstract
The utility model provides a kind of breaker closing holding meanss for improving secondary component reliability, it has separating brake semiaxis, closing a floodgate keeps connecting lever, it is characterised in that：Further include separating brake buckle and the sincere son of separating brake, the separating brake buckle and the sincere son of separating brake are splits, and the sincere son of separating brake is serially connected by axis pin and separating brake buckle, in separating brake and making process, separating brake buckle is fixed, and the sincere son of separating brake can be rotated around the axis pin compared with separating brake buckle.The torsion for substantially reducing separating brake semiaxis reduction torsion spring of the utility model reduces tripping force, reduces switching winding power and electric current, easy to operate, thus has reached the reliability engineering effect for improving secondary component.
Description
Technical field
The utility model belongs to technical field of electricity, is related to breaker, and in particular to it is reliable that one kind can improve secondary component
The breaker closing holding meanss of property.
Background technology
At present, the separating brake pallet of breaker and separating brake buckle are typically integrated design, separating brake button in making process
Plate rotates counterclockwise, and separating brake buckle when position of closing a floodgate returns clockwise under reset torsion spring torque force effect, while separating brake semiaxis
It is resetted clockwise under reduction torsion spring effect.Reliable to ensure to close a floodgate, separating brake semiaxis reset torsion spring torque force must be sufficiently large, it is sufficient to
It is resetted in place in combined floodgate roller and buckle Contact, Cai Nengshi mechanisms keep closing position.But so, but there is technologies
Deficiency, for example, separating brake semiaxis tripping force is very big, manual brake separating is difficult, and switching winding power is also excessive with electric current, often results in this
A little secondary component fluctuation of service and secondary failure, can influence the reliability and service life of breaker, make cost higher, without
Ji；When serious, can also breaker be caused to burn.
Utility model content
The purpose of this utility model is that in order to make up for the deficiencies of the prior art, providing one kind, can to improve secondary component reliable
The breaker closing holding meanss of property.
In order to reach the purpose of this utility model, technical solution is as follows：
A kind of breaker closing holding meanss for improving secondary component reliability, including separating brake semiaxis (1), closing a floodgate keeps
Connecting lever (2), roller (3), the left side mechanism plate (7) of breaker, it is characterised in that：The separating brake semiaxis (1) is connected by bearing
On the left side mechanism plate (7) of breaker, the roller (3) keeps connecting lever (2) to be connected by pivot pin with closing a floodgate, and further includes separating brake
Buckle (6) and separating brake are sincere sub (4), and the separating brake buckle (6) and separating brake sincere sub (4) are splits, and separating brake sincere sub (4) passes through axis pin
(5) it is serially connected with separating brake buckle (6), the separating brake semiaxis (1) is amplexiformed with separating brake buckle (6) and mutually rotated；In separating brake
In making process, separating brake buckle (6) is fixed, and separating brake sincere sub (4) can be around the axis pin (5) compared with separating brake buckle
(6) rotate.
Further, torsional spring being also arranged on the axis pin (5), one end of the torsional spring is connected with the separating brake buckle (6),
The other end (4) sincere with separating brake is connected.
Compared with prior art, the advantageous effects of the utility model：
Separating brake buckle and separating brake pallet are separated, separating brake pallet is connected by axis pin and torsional spring with separating brake buckle, makes combined floodgate
In the process, separating brake semiaxis is motionless, always in holding position, making process separating brake pallet rotate counterclockwise and separating brake buckle not
It is dynamic.So as to substantially reduce the torsion of separating brake semiaxis reduction torsion spring, reduce tripping force, reduce switching winding power and electric current, behaviour
Facilitate, thus reached the reliability engineering effect for improving secondary component；And then the reliability of breaker is also improved,
Effectively breaker is avoided to burn.
Description of the drawings
Fig. 1 is the combined floodgate schematic diagram of the utility model.
Fig. 2 is the separating brake schematic diagram of the utility model.
In figure, 1-- separating brake semiaxis, 2--, which close a floodgate, keeps connecting lever, 3-- rollers, the sincere son of 4-- separating brakes, 5-- axis pins, 6-- separating brakes
The left side mechanism plate of buckle, 7-- breakers.
Specific embodiment
In the following, the embodiment of the utility model is further described with reference to attached drawing.
As depicted in figs. 1 and 2, it is the breaker closing holding meanss schematic diagram of the present embodiment and separating brake schematic diagram, has
Separating brake semiaxis 1, the separating brake semiaxis 1 are connected to by bearing on the left side mechanism plate 7 of breaker, close a floodgate keep connecting lever 2 and
Separating brake buckle 6 and separating brake sincere sub 4 are further included, wherein separating brake buckle 6 and separating brake sincere sub 4 is split, and separating brake sincere sub 4 passes through axis pin
5 are serially connected with separating brake buckle 6, and in separating brake and making process, separating brake buckle 6 is fixed, and separating brake sincere sub 4 can be around
The axis pin 5 is rotated compared with separating brake buckle 6.The separating brake semiaxis 1, which is amplexiformed but is not fixed with separating brake buckle 6, to be connected, and can phase
Mutually rotate.Torsional spring is also arranged on axis pin 5, one end of torsional spring is connected with separating brake buckle 6, and the other end is connected with separating brake sincere sub 4.
It in making process, closes a floodgate and connecting lever 2 is kept to rotate, the compacting sincere son of separating brake of roller 3 for closing a floodgate and keeping on connecting lever 2 is fixed on by pivot pin
4, rotate separating brake sincere sub 4, separating brake semiaxis 1 is motionless, and separating brake pallet 4 turns counterclockwise in holding position, making process always
It is dynamic and separating brake buckle 6 is motionless.
