Abstract
The utility model relates to a fully-closed protective shield which is characterized in that the two sides of the rear portion of a cabinet top lintel are provided with guide rail supports, the upper ends of the guide rail supports are provided with guide rails, a support is disposed on the guide rails, a protective shield body is installed on the top of the cabinet, the front portion of the protective shield body is provided with a front stop edge, the rear portion of the protective shield body is provided with a rear stop edge, and the protective shield body is provided with side stop edges on the two sides. The problem in the prior art is solved that accidents may occur when a foreign body on the top of the cabinet happens to spring to be between two miniature buses or gnawing of mice causes short circuit between miniature buses. The fully-closed protective shield enables miniature buses of the top of the cabinet to be free of influence of various external adverse factors such as dust, water drops, falling foreign bodies, insects and mice and improves the safety performance of the cabinet.
Description
Technical field
The utility model is a kind of protective cover of protecting electric power cabinet cabinet to push up little bus, is a kind of totally-enclosed protective cover specifically.
Background technology
The electric power protection cabinet of installing in transformer station, little bus generally all can be installed in cabinet top, for mutual connection between row's rack.Little bus is fixed on cabinet by special geometrical clamp, before and after every little bus, has certain space in vain, ensures not contact mutually, and the little bus left and right between cabinet and cabinet connects.
Before the present utility model; in order to protect electric power cabinet cabinet to push up little bus; generally can require little bus to wrap insulating sleeve; or add that on cabinet top a four sides is unlimited, only pad pillared large top covers with four; can be because of water droplet or dropping of foreign matter and cause short circuit to ensure that cabinet pushes up between little bus not, accidents caused.The defect of these methods is, for some conditions better, newer transformer station, cabinet top does not have foreign matter and drops, do not have yet worm mouse to destroy, safer comparatively speaking; But the transformer station poor for some conditions, the time is grown, when cabinet top have foreign matter just bullet fall while causing the short circuit between little bus between two little buses or due to gnawing of worm mouse, the generation that will cause the accident.
Summary of the invention
The purpose of this utility model is just to overcome above-mentioned defect, designs, develops a kind of totally-enclosed protective cover.
The technical solution of the utility model is:
Totally-enclosed protective cover, its technical characteristics is both sides, enclosure top lintel rear portion mounting guide rail support respectively, and rail brackets upper end mounting guide rail, arranges support on guide rail, and protective cover is arranged on rack top.
Before described protective cover, be provided with front rib, rear portion is provided with rear rib, and both sides are provided with side block limit.
Lower end, described arranged on left and right sides side block limit connects respectively left plate, right plate.
The front rib lower end welded limiting angle bar of described protective cover, leaves certain interval between front rib and spacing angle bar, forms draw-in groove.
Advantage of the present utility model and effect are according to on-the-spot actual conditions, consider installation and the instructions for use of little bus, this novel protective cover of design, efficiently solve the unfavorable factor in the various external worlds such as comprising dust, water droplet, the foreign matter dropping, worm mouse is pushed up little bus impact on cabinet, improved the security performance of rack.

In figure, each label represents that corresponding component names is as follows:
Rack 1, lintel 2, little bus 3, support 4, guide rail 5, rail brackets 6, protective cover 7, spacing angle bar 8, left plate 9, right plate 10, front rib 11, draw-in groove 12, rear rib 13, side block limit 14.
Embodiment
Technical thought of the present utility model is:
According to the architectural feature on electric power cabinet cabinet top, design a kind of protective cover by steel plate bending moulding, width and rack are wide, depth ratio cabinet is deeply smaller, highly exceed cabinet and push up the certain distance of little bus, two side periphery reserving installation hole positions, middle unlimited to ensure that little bus can be connected with the little bus of another enclosure top.Yu Guiding rear portion, protective cover one end is fixed, and before the other end and cabinet, lintel top is fixed, and the reserved installing hole in side can be installed baffle plate, and after install both sides, mid portion just forms the space of a sealing, and little bus has just been subject to reliable protection in centre.Two sides that are generally the rack of the left and right sides of row's rack respectively fill a side shield, like this, form the space of a sealing once the centre of row's rack, and little bus just can not be subject to the destruction of extraneous foreign matter in the time being connected to each other.
Illustrate below.
As shown in Figure 1,2,3, 4:
Rack is installed lintel 2 before 1 top, lintel 2 both sides, rear portion mounting guide rail supports 6, and rail brackets 6 upper end mounting guide rails 5, clamp (little bus) support 4 on guide rail 5, and the support 4 of both sides is clamped little bus 3 jointly; Protective cover 7 is arranged in enclosure top, and its top is higher than little bus 3, before be provided with front rib 11, front rib 11 lower end welded limiting angle bar 8, leave certain interval between front rib 11 and spacing angle bar 8, form draw-in groove 12; Protective cover 7 rear portions are provided with rear rib 13, and both sides are provided with side block limit 14, and left plate 9 and right plate 10 are installed respectively in 14 both sides, side block limit.
The utility model application process is described as follows;
Lintel 2 is installed in rack 1 front, top in advance, lintel 2 both sides, rear portion mounting guide rail supports 6, and rail brackets 6 upper end mounting guide rails 5, clamp 1 row's support 4 on guide rail 5, and the support 4 clamping on the guide rail 5 of left and right 2 sides is corresponding one by one; Rack 1 arrives behind user scene, cabinet is installed and is pushed up little bus 3, in upper end, cabinet top, protective cover 7 is installed; Protective cover 7 width and rack 1 are wide, and depth ratio rack 1 degree of depth is smaller, and the reserved height space in rack 1 top ensures safe distance enough between little bus 3 and protective cover 7; The top that the draw-in groove 12 that the front rib 11 of protective cover 7 front portions and 8 welding of spacing angle bar form just can block lintel 2, ensures that the rear above-below direction above of protective cover 7 installations does not rock; On the rear rib 13 at protective cover 7 rear portions, be reserved with fixing hole, can be fixed with the top of rack 1, ensured like this stability of protective cover 7 at rear portion, cabinet top.Like this after installation, before and after rack 1 top has just formed, top seal and unlimited space, left and right, cabinet pushes up little bus and is arranged on this interior volume.If user only has at scene 1 rack, so as long as left plate 9 and right plate 10 are installed respectively in side shield 14 outsides of protective cover 7 both sides, can form on cabinet top the space of sealing; If scene is 1 row's rack, as long as in side shield 14 outsides of these the 1 row left and right outermost protective cover of rack 7 both sides, left plate 9 and right plate 10 are installed respectively, can form on the cabinet top of this 1 row rack the space of sealing.
In sum, this novel totally-enclosed protective cover, efficiently solves the unfavorable factor in the various external worlds such as comprising dust, water droplet, the foreign matter dropping, worm mouse is pushed up little bus impact on cabinet, has improved the security performance of rack.
