Description

Solid insulation ring main unit three station interrupter
Technical field
The utility model relates to the technical field of system for distribution network of power switchgear, especially a kind of solid insulation ring main unit three station interrupter.
Background technology
At present, on market, most solid insulation ring main unit three station interrupter only has manual operation function, does not have electric operating function, and manual operation adopts stage clip to store power mode, and spring is storage power in a compressed state, but mechanism is easily by misoperation.
In addition, be employing two operating axis in ground connection operation and combined floodgate, isolated operation, operate very inconvenient, space hold is comparatively large simultaneously, and mechanism element is many, cannot dress up component models in advance.
Utility model content
The technical problems to be solved in the utility model is: in order to solve the problem proposed in above-mentioned background technology, and the utility model provides a kind of modularization solid insulation ring main unit three station interrupter of compact conformation.
The utility model solves the technical scheme that its technical problem adopts: a kind of solid insulation ring main unit three station interrupter, there is the bracing frame of frame-type structure, the middle part of support frame as described above is provided with the operating axis running through its front/rear end, described operating axis is arranged with the torsion spring being positioned at bracing frame inside, the rear end of described torsion spring is connected with pressing plate, the part that operating axis stretches out in outside supporting framing front end face is provided with connecting lever, described connecting lever is connected with and wins in succession, described left end of winning in succession is connected with indication panel, and right-hand member is connected with pivoted housing; The interior rear wall of bracing frame is provided with and is positioned at roller on the left of pressing plate and sincere son, described sincere son is connected with pivot pin, the interior front and rear wall of bracing frame is provided with the auxiliary switch be connected with pivoted housing.
For the ease of Electronic control operating axis, therefore the top of support frame as described above is provided with motor, is connected with electric transmission part between described motor and operating axis.
The beneficial effects of the utility model are: solid insulation ring main unit three station interrupter of the present utility model has following positive advantage:
One, this three stations interrupter adopts Modular Structure Design, assembled in advance can become a global facility, and is connected with the isolating switch of solid insulation ring main unit by operating axis entirety;
Two, this three stations interrupter adopts torsion spring to store power mode, and the torsion spring of peacetime state does not have energy, only has torque spring energy store discharging in operation, effectively avoids mechanism that misoperation phenomenon occurs;
Three, the compact conformation of whole three station interrupters, saves space, convenient for installation and maintenance;
Four, in addition, the combined floodgate of this three stations interrupter, isolation, ground connection operation all complete on same operating axis, and can the motion of Non-follow control operating axis or the motion of Electronic control operating axis.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the structural representation of using state of the present utility model.
Label in accompanying drawing is: 1, bracing frame, 2, motor, 3, operating axis, 4, electric transmission part, 5, torsion spring, 6, pressing plate, 7, connecting lever, 8, pivoted housing, 9, indication panel, 10, win in succession, 11, roller, 12, sincere son, 13, pivot pin, 14, auxiliary switch, 15, isolating switch.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As depicted in figs. 1 and 2, solid insulation ring main unit three station interrupter, there is the bracing frame 1 of frame-type structure, the top of bracing frame 1 is provided with motor 2, electric transmission part 4 is connected with between motor 2 and operating axis 3, the middle part of bracing frame 1 is provided with the operating axis 3 running through its front/rear end, operating axis 3 is arranged with the torsion spring 5 being positioned at bracing frame 1 inside, the rear end of torsion spring 5 is connected with pressing plate 6, the part that operating axis 3 stretches out in outside bracing frame 1 front end face is provided with connecting lever 7, connecting lever 7 is connected with and wins 10 in succession, win in succession 10 left end be connected with indication panel 9, win in succession 10 right-hand member be connected with pivoted housing 8, the interior rear wall of bracing frame 1 is provided with the roller 11 and sincere sub 12 be positioned on the left of pressing plate 6, is connected with pivot pin 13 on sincere sub 12, the interior front and rear wall of bracing frame 1 is provided with the auxiliary switch 14 be connected with pivoted housing 8.
As depicted in figs. 1 and 2, this three stations interrupter is in earthing position, when Non-follow control operating axis 3 or by motor 2, during electric transmission part 4 control operation axle 3, operating axis 3, connecting lever 7 and pressing plate 6 are rotated counterclockwise, drive torsion spring 5 energy storage, after turning an angle, the pivot pin 13 on sincere sub 12 depressed by pressing plate 6, sincere sub 12 are impelled to throw off with roller 11, and continue to be rotated counterclockwise under torsion spring 5 acts on, sincere sub 12 are made to keep with next roller 11, get to isolated bit rapidly, simultaneously, connecting lever 7 drives pivoted housing 8 respectively, to win in succession 10 rotations, auxiliary switch 14 is switched, indication panel 9 forwards isolated bit instruction to, when operating axis 3 continues to be rotated counterclockwise, same principle, gets to closing position, otherwise during when Non-follow control operating axis 3 or by motor 2, electric transmission part 4 control operation axle 3, operating axis 3, connecting lever 7 and pressing plate 6 turn clockwise, and can realize closing position, isolated bit and ground connection position successively.
As shown in Figure 3, this three stations interrupter is connected with outside isolating switch 15 by operating axis 3.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification, must determine its technical scope according to right.
