Abstract
The utility model provides an insulator foot for cubical switchboard skeleton, including the bottom plate, the four sides of this bottom plate are provided with preceding shrouding, side seal board and back shrouding, and preceding shrouding is provided with preceding shrouding mounting hole, bottom plate, side seal board and back shrouding formula beta structure as an organic whole, the height that highly is greater than the back shrouding of side seal board, the height that highly is greater than preceding shrouding of back shrouding, the bottom plate still is provided with cable pit wiring hole and a plurality of footing mounting hole. Owing to adopted above -mentioned technique, the utility model discloses a preceding shrouding, back shrouding and side seal board have been set up around the bottom plate to utilize the special insulating cement of PC to seal, thus very big improvement the insulating properties of cabinet body base, and finally reached the actual demand of satisfying cubical switchboard insulating properties.
Description
Technical field
The utility model relates to switch cubicle assembling field, particularly relates to a kind of insulator foot for switch cubicle skeleton.
Background technology
Along with the quickening of Urbanization in China, the raising of Urban Transportation ability is one of key factor determining urbanization process development speed.In recent years, flourish along with urban rail transit in China cause, subway has become the main tool of urban transportation.Because subway traction power supply adopts DC power supply, after traction power source positive and negative electrode does not take insulation measures to contact with the earth, electric current flows into buried metal, flow out from buried metal body again, enter in the earth or water, because outflow of bus current position becomes anode, then there is fierce corrosion at outflow of bus current position.In view of the particularity of structure of the subway, for preventing stray electrical current, subway tunnel structure metal (reinforcing bar and built-in metal pipeline etc.) is corroded, cause potential safety hazard to prevent positive pole from producing potential difference with ground especially, the positive and negative electrode power distribution cabinet of trailer system all adopts insulation against ground to install.
Frame protection is distinctive protect types in DC power-supply system, and conductor rail is positive pole, and rail is negative pole.Electric current, except returning from rail, can also return from the earth, and such stray electrical current is very large, so DC power-supply system is designed to isolated neutral system.But device housings is ground connection, if there is plus earth, positive pole is increased suddenly by the short circuit current between device housings anticathode, and rail and body shell are connected to negative pole, and passenger gets on or off the bus will have serious life danger.Frame protection detects the insulation status between the DC suppling equipment positive pole of insulation against ground and the cabinet of ground connection in real time, in a short-circuit situation, acts on DC circuit breaker tripping operation.DC traction system plus or minus one pole ground connection does not have anything to endanger, but two-stage is all very large on DC equipment impact after ground connection, may burn out direct-flow electricity utilization apparatus or make direct-flow electricity utilization apparatus cisco unity malfunction, therefore must carry out insulating mounting.
The equipment such as direct-current switch cabinet, braking energy absorption plant, braking energy consumer, earth protective device, rectifier, negative pole cabinet, online/upper rail isolating switch cabinet that insulator arrangement is applicable to draw step-down mixing electric substation is installed and used.
Nowadays, because the cabinet body structure of the switch cubicle of each manufacturer production is different, so existing switch cubicle generally adopts plate armature; But this kind of structure insulating properties is after mounting poor, the actual demand that switch cubicle is installed cannot be met.
Utility model content
In order to solve the problem, the utility model provides a kind of insulator foot for switch cubicle skeleton, can improve insulation property further on the basis of existing base of switch cabinet.
Above-mentioned a kind of insulator foot for switch cubicle skeleton, comprise base plate, four limits of described base plate are provided with front shrouding, side seal board and rear shrouding, described front shrouding is provided with front shrouding installing hole, described base plate, side seal board and rear shrouding are integral type foldable structure, the height of described side seal board is greater than the height of rear shrouding, and the height of described rear shrouding is greater than the height of front shrouding; Described base plate is also provided with cable trough wiring hole and several foot mounting holes.
In said apparatus, described base plate and the gap between front shrouding, side seal board and rear shrouding are sealed by PC special isolation glue.
In said apparatus, described base plate is PC plate.
In said apparatus, the thickness of described PC plate is 3mm.
In said apparatus, the quantity of described foot mounting hole is 4.
Advantage of the present utility model and beneficial effect are: the utility model provides a kind of insulator foot for switch cubicle skeleton, by shrouding before the surrounding of base plate is provided with, rear shrouding and side seal board, and utilize PC special isolation glue to seal, thus greatly improve the insulation property of bottom base of cabinet body, and finally reach the actual demand meeting switch cubicle insulation property.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of insulator foot in the utility model;
Fig. 2 is the vertical view of insulator foot in the utility model.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection range of the present utility model with this.
As depicted in figs. 1 and 2, the utility model describes a kind of insulator foot for switch cubicle skeleton, comprises base plate 1, and four limits of this base plate 1 are provided with front shrouding 11, side seal board 12 and rear shrouding 13;
Wherein, front shrouding 11 is provided with front shrouding installing hole 111, so that the installment work of front shrouding 11; Meanwhile, in order to adapt to process requirements, above-mentioned base plate 1, side seal board 12 and rear shrouding 13 are the foldable structure of integral type; In addition, consider and to mate between cabinet skeleton, so the height of side seal board 12 is greater than the height of rear shrouding 13, then the height of shrouding 13 is greater than the height of front shrouding 11.
Preferably, above-mentioned base plate 1 and the gap between front shrouding 11, side seal board 12 and rear shrouding 13 are sealed by PC special isolation glue, and base plate 1 have employed the thick PC plate of 3mm.
Further, base plate 1 is also provided with cable trough wiring hole 14 and several foot mounting holes 15, the concrete size of this cable trough wiring hole 14 can be determined according to actual process demand; Meanwhile, consider the steadiness of installation, so have employed 4 foot mounting holes 15 altogether, and 4 foot mounting holes 15 with the formal distribution of 2 group in the both sides of cable trough wiring hole 14, thus add the steadiness of installation.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
