Embodiment
Understand for technical characterictic, purpose and effect to utility model have more clearly, contrast the embodiment of description of drawings the utility model at present, identical label is represented identical or structural similarity but the identical part of function in each figure.
For making drawing succinct, only schematically shown out the part relevant among each figure with the utility model, they do not represent its practical structures as product.In addition, so that drawing succinctly is convenient to understand, the parts that in some figure, have same structure or function have only schematically illustrated one of them, or have only marked one of them.
Fig. 2 is the perspective view of a kind of exemplary embodiment of handcart assembly of switch cubicle, has shown three handcart assemblies among the figure, but only schematically draws the contact 40 of a handcart assembly.As shown in the figure, handcart assembly comprises an assembled plate 10, insulation contact arm 20, a voltage transformer 50 and a lightning arrester 60.One end of one end, voltage transformer 50 and the lightning arrester 60 of insulation contact arm 20 is fixed on the assembled plate 10.Be provided with three voltage transformers 50 in the execution mode shown in Figure 2, but the voltage transformer of respective numbers can be set as required.The other end of insulation contact arm 20 is provided with a contact 40, and the other end of lightning arrester 60 is electrically connected contact 40.
As shown in Figure 2, insulation contact arm 20 is provided with one and is used to hold fuse 30 (referring to Fig. 3) spatial accommodation 24, and spatial accommodation 24 is between assembled plate 10 and contact 40.Lightning arrester 60 and voltage transformer 50 are separately positioned on the relative both sides of insulation contact arm 20, to guarantee the safe isolation distance between lightning arrester and the voltage transformer.
Compare with the handcart assembly among Fig. 1; Handcart assembly among Fig. 2 has omitted insulator (referring to Fig. 1); Through realize by the insulation contact arm 20 of insulating material preparation and assembled plate 10 between electrical isolation, thereby shortened the size of handcart assembly in the illustrated direction of arrow (depth direction of switch cubicle), wherein assembled plate 10 is only bent by a block plate and forms; And insulation board 22 is formed by the insulating sheet material cutting, and is easily manufactured.Simultaneously, the handcart assembly can be installed lightning arrester 60, fuse 30 and voltage transformer 50 simultaneously, makes the handcart assembly have all functional modules, has guaranteed the fail safe that the handcart assembly uses.Fuse is arranged in the spatial accommodation, can have avoided the use of the voltage transformer of fuse integrated, increased the model range of choice of voltage transformer, improved the compatibility of handcart assembly.
As shown in Figure 2; Insulation contact arm 20 comprises two insulation boards that are oppositely arranged 22; One end of insulation board 22 is fixed on the assembled plate 10, and the gap between 40, two insulation boards 22 of other end supports contacts forms a spatial accommodation 24; Fig. 3 has shown the partial structurtes sketch map behind insulation board 22 of handcart assembly dismounting of a switch cubicle among Fig. 2, has only schematically shown an insulation contact arm 20 among the figure.As shown in Figure 3, fuse 30 is arranged in two spatial accommodations 24 between the insulation board 22, and fuse 30 1 ends are connected with contact 40, and the other end is connected in voltage transformer 50 through connecting plate 32.Voltage transformer 50 1 ends are resisted against on the assembled plate 10, and its terminals are towards fuse 30.
Though in Fig. 2 and execution mode shown in Figure 3, insulation contact arm 20 comprises two insulation boards that are oppositely arranged 22, the structure of insulation contact arm is not limited only to this, and it can also be the pipe of U-lag or hollow, as long as can form the spatial accommodation of laying fuse.
Above-mentioned handcart assembly through existing contact arm being changed into the insulation contact arm of the utility model, can omit insulator thus, thereby shortens the size of handcart assembly on the switch cubicle depth direction.Through the adjustment fuse, the relative position between lightning arrester and the voltage transformer can all be installed on these functional units in the handcart assembly; Guaranteed that the handcart assembly has function completely; Simultaneously, can also guarantee fuse, lightning arrester and voltage transformer safe distance each other; Avoid the use of extra barrier assembly, thereby reduced the influence of rival car assembly processing assembling.
In this article, " schematically " expression " is served as instance, example or explanation ", should any diagram, the execution mode that be described to " schematically " in this article be interpreted as a kind of preferred or have more the technical scheme of advantage.
Be to be understood that; Though this specification is described according to each execution mode; But be not that each execution mode only comprises an independently technical scheme, this narrating mode of specification only is for clarity sake, and those skilled in the art should make specification as a whole; Technical scheme in each execution mode also can form other execution modes that it will be appreciated by those skilled in the art that through appropriate combination.
The listed a series of detailed description of preceding text only is specifying to the feasibility execution mode of the utility model; They are not the protection range in order to restriction the utility model, allly do not break away from equivalent execution mode or the change that the utility model skill spirit done and all should be included within the protection range of the utility model.
