Further, it is described also including the elastic wire-unfolding rack between the chamber door and the power cord winding disk Elastic unwrapping wire folder includes the support being fixed on the base, and the card line folder for being fixed on the upper end of the support.
Further, the card line folder is U-shaped elastic clip, and the support is inverted V-shaped frame, the bottom two of the inverted V-shaped frame End is respectively arranged with one and is screwed plate.
Further, many anti-blocking posts are vertically and fixedly provided with the inside bottom surface of the end cap, the length of the anti-blocking post is big In the length equal to the logical spool.
Technical solutions of the utility model have the beneficial effect that:By pre-installing rotating shaft in the case of maintenance power box, and It is rotatably arranged on the power cord winding disk in rotating shaft so that staff can quickly put into work without power autonomous line Make.Wherein, demarcation strip separates the work about electric power component and power cord winding disk of power supply box, it is to avoid influence each other, and separates One end clamping of the power line that the solidus draw-in groove on plate will can draw on power cord winding disk, wiring is connected after making its clamping again Terminal is difficult to loosen, and the other end of power line then can be passed to be stretched to and used at a distance by logical spool, threading hole, pull power supply Chamber door can be shut during line, prevents other objects from entering influence normal work in cartonning, end cap is provided for usually in case Threading hole is blocked, prevents other objects from entering in cartonning to cause through threading hole to damage.
Brief description of the drawings
In order to illustrate more clearly of the technical scheme in the utility model embodiment, below will be to needed for embodiment description The accompanying drawing to be used is briefly described, it should be apparent that, drawings in the following description are only some realities of the present utility model Example is applied, for those of ordinary skill in the art, on the premise of not paying creative work, can also be according to these accompanying drawings Obtain other accompanying drawings.
Fig. 1 is a kind of one structural representation of maintenance power box for transformer station that the utility model embodiment is provided Figure;
Fig. 2 is a kind of for the maintenance power box secondly structural representation of transformer station of the utility model embodiment offer Figure;
Fig. 3 is the A portions mplifying structure schematic diagram of Fig. 2.
Specific embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
Refer to shown in Fig. 1 ~ Fig. 3, the utility model provides a kind of maintenance power box for transformer station, the maintenance Power supply box includes casing 1, the open-topped cover plate 2 for sealing the casing 1, is opened for sealing the front end of the casing 1 The chamber door 3 and the base 4 for sealing the bottom opening of the casing 1 of mouth, total air switch 5 is provided with the casing 1 And at least one point of air switch 6 electrically connected with total air switch 5, described point of air switch 6 be electrically connected with wiring A demarcation strip 8 for the casing 1 to be divided into upper and lower two spaces is horizontally arranged with terminal 7, the casing 1, it is described Rotating shaft 9 is installed on the base 4 of the lower section of demarcation strip 8, is rotated in the rotating shaft 9 and is arranged with power cord winding disk 10, described point The side of the close described chamber door 3 of dividing plate 8 is provided with solidus draw-in groove 11, and threading hole 12, the chamber door are provided with the chamber door 3 3 inner side is provided with the logical spool 13 coaxial with the threading hole 12, and the end thread of the logical spool 13 is connected with end cap 14.
Specifically, by the pre-installation rotating shaft 9 in the case of maintenance power box, and it is rotatably arranged on the power supply in rotating shaft 9 Line wire spool 10 so that staff can quickly devote oneself to work without power autonomous line.Wherein, demarcation strip 8 is by power supply The work about electric power component and power cord winding disk 10 of case are separated, it is to avoid influenced each other, and the solidus draw-in groove 11 on demarcation strip 8 can One end clamping of the power line will be drawn on power cord winding disk 10, makes to connect binding post 7 after its clamping again and is difficult to loosen, The other end of power line then can be passed to be stretched to by logical spool 13, threading hole 12 and used at a distance, can be with when pullling power line Chamber door 3 is shut, prevents other objects from entering influence normal work in cartonning, being provided for of end cap 14 blocks logical usually in case String holes 12, prevents other objects from entering in cartonning to cause through threading hole 12 to damage.Above-mentioned total air switch 5, point air switch 6, connect Line terminals 7 are the conventional components in power supply box.It is readily apparent that also have other related components in power supply box, but it is not this reality With new improvement, its operation principle is to know in the industry, be will not be repeated here.
Used as one of which implementation method, the maintenance power box that the present embodiment is provided can also include being located at the chamber door 3 And the elastic wire-unfolding rack 15 between the power cord winding disk 10, the elastic unwrapping wire folder 15 is including being fixed on the base 4 On support 15a, and be fixed on the support 15a upper end card line folder 15b.
Specifically, the power line for being coiled on power cord winding disk 10 is more long, does not have guiding when being passed through logical spool 13 Words easily tortuous knotting etc., elastic wire-unfolding rack 15 can then be guided to the power line released, and card line folder 15b holds electricity Source line is simultaneously guided to it.
Used as the feasible design of one of which, the card line folder 15b can be U-shaped elastic clip, and the support 15a can To be inverted V-shaped frame, the bottom two ends of the inverted V-shaped frame are respectively arranged with one and are screwed plate 15c.
Wherein, being screwed on plate 15c can be provided with screw, fitted bolt will whole elasticity wire-unfolding rack 15 with screw thread Fixed mode is arranged on base.
Improved as one of which, many anti-blocking posts 16 are vertically and fixedly provided with the inside bottom surface of the end cap 14, it is described anti- The length of the length more than or equal to the logical spool 13 of stifled post 17.
Specifically, it is hollow to lead to inside spool 13, is usually easy to accumulate some debris, is also easily clogged by people's malice Object is blocked, and power line unwrapping wire can be influenceed after blocking.The design of anti-blocking post 16 then can be in the pipe for usually clogging logical spool 13 Space, then can together be taken out of anti-blocking post 16 by turning on end cap 14 when logical line is needed, very convenient.
The above is only preferred embodiment of the present utility model, and protection domain of the present utility model is not limited merely to Above-described embodiment, all technical schemes belonged under the utility model thinking belong to protection domain of the present utility model.Should refer to Go out, for those skilled in the art, some improvement under the premise of the utility model principle is not departed from and Retouching, these improvements and modifications also should be regarded as protection domain of the present utility model.
