Abstract
The utility model relates to a tubular busbar specially for power supply for a high-rise building floor. The tubular busbar comprises an insulated plastic cover plate; and four tubular conductors with uniform sections are packaged in the insulated plastic cover plate, are separated by an insulated upper clamp plate and an insulated lower clamp plate and are clamped and fixed on a steel plate lower groove. And the external diameters of the tubular conductors are fixed; and the internal diameters thereof are gradually increased from bottom to top. Because the tubular conductors are separated and fixed by employing the insulated upper clamp plate and the insulated lower clamp plate, so that the tubular conductors are isolated from each other by the air and the heat radiation conditions of the conductors become good; and a phenomenon of short circuit due to the damage on an insulating part according to the existing bus duct in the prior art can be avoided. Because the tubular conductors employ the mode of conductor cross section changing due to the internal diameter changing, the changing of adaptive currents of conductor cross sections can be changed flexibly, the copper material is saved, and the uniformity and consistency of accessories can be realized due to the unchanged external diameters to realize convenient installation and maintenance.
Description
Technical field
The utility model relates to a kind of low-voltage electrical equipment of large electric current short-distance transmission, particularly the special-purpose cast bus bar of a kind of skyscraper floor power supply.
Background technology
Current, the mode of skyscraper floor power supply has: the modes such as plug-board bus bar (being commonly called as bus duct), power cable, heavy in section insulated conductor tap.The aforesaid way contact is too many, the conductor connection is unstable, power supply reliability is poor, the copper wasting of resources is large, and the faults such as the oxidation of ubiquity conductor contact face, node heating, switch trip occur repeatedly after long-play.
Large quantities of tall buildings are being sought stable performance, colory floor power supply equipment special; Completed for use for many years skyscraper, the reasons such as, security incident multiple owing to having a power failure are also looked forward to the appearance of high-quality floor powered products.The reflection of these problem property maintenance department is also more and more stronger.
Summary of the invention
In order to overcome the defective of above-mentioned prior art, the purpose of this utility model is to provide a kind of skyscraper floor power supply special-purpose cast bus bar, can guarantee safe and reliable power supply, and reasonable saving copper resource, be convenient to installation and maintenance again.
In order to achieve the above object, the technical solution of the utility model is achieved in that
The special-purpose cast bus bar of a kind of skyscraper floor power supply, comprise ambroin cover plate 10, being packaged with 3, four uiform section cast conductors 3 of four uiform section cast conductors in ambroin cover plate 10 separates and is fixedly clamped on groove 9 under steel plate by insulation train wheel bridge 5 and insulation lower plate 7.
Described cast conductor 3 external diameters are certain, and it is large that internal diameter becomes from lower to upper step by step.
The utlity model has following advantage:
1, cast conductor 3 employing insulation train wheel bridges 5 and insulation lower plate 7 are separately fixing, make and lean on air insulation between cast conductor 3, and the radiating condition of conductor is better, and can not have as the prior art bus duct because of the damaged phenomenon that causes short circuit of insulating part.
2, cast conductor 3 adopts and changes the mode that internal diameter changes cross-sectional area of conductor, can change neatly the variation that cross-sectional area of conductor adapts to electric current, and the saving copper material can realize because external diameter is constant that again accessory is unified consistent, easy to installation and maintenance.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the schematic diagram of the utility model cast conductor 3.
Embodiment
Below in conjunction with accompanying drawing, structural principle of the present utility model and operation principle are done and be described in detail.
With reference to Fig. 1, the special-purpose cast bus bar of a kind of skyscraper floor power supply, comprise ambroin cover plate 10, being packaged with 3, four uiform section cast conductors 3 of four uiform section cast conductors in ambroin cover plate 10 separates and is fixedly clamped on groove 9 under steel plate by insulation train wheel bridge 5 and insulation lower plate 7; Train wheel bridge 5 connects by fishbolt 2 with the lower plate 7 of being connected, and insulation train wheel bridge 5 is fixing by groove 9 under location-plate 4 and steel plate, and insulation lower plate 7 is fixing by groove 9 under connecting bolt 6 and steel plate.
With reference to Fig. 2, described cast conductor 3 external diameters are constant, and it is large that internal diameter becomes from lower to upper step by step.Due to the electric current of the cast conductor 3 of flowing through, reduce step by step (common 5 layers are one-level) from the first floor to top layer, rationally use copper material for adapting to this variation, make cast conductor 3 external diameters constant, internal diameter strengthens step by step from the first floor to top layer, and conductive section reduces step by step, realizes the purpose of saving copper resource.
Operation principle of the present invention is: the utility model is every just being connected by standing finish 1 between 600mm and body of wall 8, each building unit uses a utility model, each floor can use one section the utility model that equates with story height, one section little bus is drawn in every junction between two-layer, an air circuit is installed, power consumption control switch as this floor, and the junction adopts arc pressuring plate to be bolted, make between conductor to connect more reliably, do not have the oxidative phenomena of contact-making surface.
