The vertical plate type breaking device comprises a framework, a breaking device is fixedly arranged in the framework, and the vertical plate type breaking device is characterized in that a vertical plate is fixedly arranged in the framework, and the breaking device is arranged on the vertical plate. The vertical plate type breaking device is mostly characterized in that the structure is simple and realization is easy and is advantageous in that precise cooperation and positioning of all elements are guaranteed, installation is convenient and reliable, the product is durable, the usage performance is raised, and the service life is prolonged.
Description
affiliated technical field
The utility model discloses a kind of switching-off device of vertical plate type vacuum circuit-breaker, belong to the electric equipment products technical field, the switching-off device of the vacuum circuit-breaker of applying in the high-tension switch cabinet especially be complementary with control section in the high pressure transmission and distribution networks is relevant.
Background technology
Vacuum circuit-breaker is the core component in high-tension switch cabinet, is applied to the electric power network field, and switching-off device is again the key component of vacuum circuit-breaker.The operation conditions of switching-off device plays critical effect to the transmission quality of electric power network.
The multiplex semiaxis snapping of the switching-off device of known vacuum circuit-breaker or buckle snapping, the switching-off device of this semiaxis snapping or buckle snapping in use has that intensity is lower, unstable properties and the defect such as parts are easy to wear.The installation of existing switching-off device in vacuum circuit-breaker mainly contains two kinds of structures, a kind of is rearmounted fastening installation, this mounting structure very easily causes the switching-off device distortion in default of assist location, thereby affects divide-shut brake stability and the overall performance of vacuum circuit-breaker; Another kind is the auxiliary installation of rearmounted fastening installation and frame plate side location, this structures shape switching-off device can only be arranged on the side near frame plate, so just caused the stressed beat of breaker main shaft, accelerate the wearing and tearing of spindle drive cell mesh, thereby affect serviceability and the useful life of vacuum circuit-breaker.Therefore, existing switching-off device is only applicable to the junior vacuum circuit-breaker product of drop-out voltage, is not suitable for the vacuum circuit-breaker product that higher grade of drop-out voltage, has limited the scope of application of vacuum circuit-breaker.
The utility model content
The intensity that the vacuum circuit-breaker switching-off device of installing for existing snapping mode exists is low, easy
Easily produce stress deformation after wearing and tearing and installation, can not guarantee to assemble the defects such as operational reliability of rear switching-off device, the utility model discloses a kind of switching-off device of vertical plate type vacuum circuit-breaker, the switching-off device of this vertical plate type vacuum circuit-breaker is that each parts are fixed on a support, be made into module, and this module whole is installed on riser.This switching-off device has overcome numerous drawbacks of current vacuum circuit-breaker switching-off device, can guarantee precision-fit and positioning precision between each parts, easy installation and reliable, improving product working strength and installation strength, improve product serviceability and useful life, the connecting-disconnecting function of product is got a promotion.
Taked following technical scheme for realizing the purpose of this utility model:
A kind of switching-off device of vertical plate type vacuum circuit-breaker, the switching-off device of this vertical plate type vacuum circuit-breaker comprises framework, is fixed with switching-off device in framework, it is characterized in that in framework being fixed with riser, switching-off device is installed on riser.
Described switching-off device comprises the separating brake support, is fixed with separating brake connecting lever and snapping piece in the separating brake support, on the separating brake connecting lever, is fixed with closing pawl.
The utility model outstanding feature is simple in structure, easy realization, and it is significantly a little precision-fit and the positioning precision that can guarantee between each parts, easy installation and reliable, and the working strength of improving product improves product serviceability and useful life.
The accompanying drawing explanation
Further describe technical characterictic of the present utility model below in conjunction with accompanying drawing:
The structural representation of Fig. 1, an embodiment of the utility model;
The A of Fig. 2, embodiment Fig. 1---A sectional structure schematic diagram;
The B of Fig. 3, embodiment Fig. 1---B sectional structure schematic diagram
In figure: 1, framework 2, construction bolt 3, switching-off device 4, side location and installation bolt 5, frame left plate 6, riser 7, main shaft 8, separating brake support 9, snapping piece 10, separating brake connecting lever 11, brace 12, closing pawl.
Embodiment
As shown in Figure 1 and Figure 2,1 in figure is framework, and 3 in figure is switching-off devices, and switching-off device 3 is modular units independently, independently detachable installation.In figure 8 is separating brake supports, in a side of separating brake support 8, with brace 11, is fixed with separating brake connecting lever 10 and snapping piece 9 in separating brake support 8, is fixed with closing pawl 12 on separating brake connecting lever 10.
The bottom surface of switching-off device 3 is fixed on separating brake support 7 by construction bolt 2, and the back of separating brake support 7 is connected on framework 1; The side of the side of switching-off device 3 and separating brake support 7 is fixed on riser 6 by side location and installation bolt 4, and face and the framework 1 of riser 6 are integrally welded.
Vacuum circuit-breaker main shaft 7 is installed in framework 1, on main shaft 7, is fixed with driving parts, the closing pawl 12 of switching-off device 3 is connected with the driving parts on vacuum circuit-breaker main shaft 7.When vacuum circuit-breaker work is rotated main shaft 7, the driving parts on main shaft 7 is maintained on closing pawl 12 after touching closing pawl 12 rotations, and separating brake connecting lever 10 snaps on snapping piece 9 simultaneously, prevents the stressed rotation of closing pawl 12, plays position-limiting action.
After having taked as above measure, the utility model produces following good effect:
1. in switching-off device, adopt gradient to subtract the power structure, made between separating brake connecting lever, closing pawl, main shaft to form good driving effect, reduced the consumption of idle work.This structure makes the separating brake actuating force greatly reduce, and has slowed down the wearing and tearing of shock loading to parts simultaneously, can improve the mechanical endurance of complete machine.
2. make brace and strengthen structure on the structure of separating brake support, and adopted brand-new after
Location and installation and vertical plate type side are installed two kinds of mounting meanss of combination, have reduced the impact that switching-off device and mechanism's stress deformation cause, and have guaranteed reliability and the accuracy of product orientation and installation, have improved the serviceability of product; Effectively guaranteed transmission accuracy and the reliable transmission of circuit breaker, product complete machine transmission performance is improved by a relatively large margin, guaranteed that breaker mechanism cut-offs greatly, long-life instructions for use.
