Embodiment
With reference to the accompanying drawings, the operating mechanism that describes vacuum circuit-breaker of the present utility model in detail prevents the selection embodiment of wear device.
Before this; term that uses in this specification and claims book or word are not to be defined in usually or the meaning on the dictionary; the utility model invention artificially illustrates the utility model of self with the best approach; can suitably define the notion of term; based on this principle, should only be interpreted as meeting the meaning and the notion of technological thought of the present utility model.
Therefore, the formation that shows in embodiment that puts down in writing in this specification and the accompanying drawing is a most preferred embodiment of the present utility model, is not whole representatives technological thoughts of the present utility model, therefore, when carrying out the application, be interpreted as to exist the multiple equipollent and the variation that can replace it.
Fig. 2 to Fig. 4 is presented in the vacuum circuit-breaker of conventional art, because of the accompanying drawing of rotation chain roller bearing at the state of the wear track portion wearing and tearing of rotational trajectory through hole.
Fig. 2 to Fig. 4 has shown the inside of breaker mechanism, and the mechanism of conventional art is a link structure.
As shown in Figure 2, when the rotational trajectory through hole 15 that is formed at header board 11 in mechanism displacement up and down takes place, make the rotation displacement of rotation chain roller bearing 12 be subjected to the constraint of set track.
The formation of the constraint rotation displacement like this of conventional art comprises the header board 11 of the front panel that forms circuit breaker, the roller bearing 12 and the connecting rod 13 of rotation chain.These are formed in the circuit breaker of the present utility model also identical, therefore following its detailed description of omission.
In Fig. 2, shown at circuit breaker and turn-offed the state that drops into spring release under (off) state, Fig. 3 has shown the state that turn-offs input spring energy-storage under (off) state at circuit breaker, and Fig. 4 has shown the state of opening input spring release under (on) state at circuit breaker.
With regard to conventional art, when Fig. 2 state exchange is Fig. 3 state, initial stage, rotation chain roller bearing 12 impinges upon the rotational trajectory through hole 150 that the angle that processes on the header board 11 is cut into circular delthyrium shape with bigger power, make the containment surfaces of the delthyrium shape of processing on header board 11 simultaneously, that is, make the 15a of the wear track portion distortion of rotational trajectory through hole 150.
After opening and closing the number of times increase, the deflection of the 15a of wear track portion further strengthens, and the reliability of the parts of formation circuit breaker 10 is low, may cause the operation of product bad.
Fig. 5 is the accompanying drawing that the operating mechanism of demonstration vacuum circuit-breaker of the present utility model prevents wear device, and Fig. 6 is the details drawing of Fig. 5.
As Fig. 5 and shown in Figure 6, vacuum circuit-breaker 10 of the present utility model can comprise: header board 11, and it forms the front panel of vacuum circuit-breaker 10; Rotational trajectory through hole 15, it is formed on the described header board 11; Rotation chain roller bearing 12, it is Zhou Xuanzhuan in described rotational trajectory through hole; And connecting rod 13, it makes described rotation chain roller bearing running.
And described rotational trajectory through hole 15 can be cut into circular leg-of-mutton through hole by the angle and form, and on the top of described rotational trajectory through hole 15, forms the 15a of wear track portion that weares and teares along with the rotary impact of described rotation chain roller bearing 12.The part of the described wear track 15a of portion is cut.In the utility model, the 15a of wear track portion is meant a jiao in the rotational trajectory through hole.
The operating mechanism of described vacuum circuit-breaker prevents that wear device from comprising stiffener 50, and the cut-away portions that it inserts the described wear track 15a of portion is used to prevent the wearing and tearing of the described wear track 15a of portion.As an example, described stiffener 50 can be through heat treated plate.
In addition, the described wear device that prevents can easily be changed it in order to make when described stiffener 50 damages, and can also comprise being used for described stiffener 50 is fixed in the fixing with plate 40 of described header board 11.
Described stiffener 50 fixingly can firmly be fixed in described header board 11 by means of binder bolt 60 with plate 40 with described.
Therefore, be assembled in described fixing usefulness plate 40 through heat treated stiffener 50 after, can utilize binder bolt 60, described stiffener 50 firmly is fixed in header board 11.So described stiffener 50 is positioned at the splitted groove of the described wear track 15a of portion.
Therefore, according to the utility model, closing of power circuit breaker, when rotation chain roller bearing 12 moves to the 15a of the wear track portion side of described rotational trajectory through hole 15, the rotation chain roller bearing 12 not direct brinelling track 15a of portion, but bump is through heat treated stiffener 50, thereby can prevent the distortion of the 15a of wear track portion.
And then described stiffener 50 of the present utility model utilizes fixing with plate 40 by means of binder bolt 60, firmly be fixed in header board 11, therefore, even under the situation that stiffener 50 damages along with using repeatedly, also can easily change, easily carry out maintenance management.
