Abstract
The utility model relates to a small-volume bus duct used for power and illumination, which consists of an insulating separation groove, a conducting bar, insulating press block(s) and a metal shell, wherein the insulating separation groove consists of a bottom plate, a side plate and clapboards; the insulating separation groove is divided into two or more separation grooves by the clapboards; a conductor is safely separated by the clapboards of the insulating separation groove; the conducting bar is positioned at the bottom of the inner side of the insulating separation groove and is arranged along the transverse direction within the plane; the conducting bar is pressed at the bottom of the insulating separation groove by the insulating press block(s); and an insulator and the conducting bar are encapsulated in the metal shell. The small-volume bus duct has the beneficial effects of being low in material cost and manpower cost, higher in waterproof and dustproof protective class, low in impedance and magnetism and high in cost performance.
Description
Technical field
The utility model relates to 80A-500A power, illumination low pressure power and distribution supply cable, especially refers to a kind of low capacity bus duct that is used for power, illumination.
Background technology
Existing intensive isolated bus groove and air insulation bus duct are because the restriction of its project organization only is applicable to the use of the above high-capacity dynamical bus of 630A main line.Concentration bus duct (see figure 3) and air type bus duct (see figure 4) are made up of busbar, insulation film, insulating support, shell, connecting bolt, and busbar adopts vertical the placement, is arranged in parallel.The intensive insulation mode that coats and twine insulation film that on busbar, adopts, the row of making closely contacts with the row plane; Air type adopts the insulation fixed support, with the isolated air insulation mode of busbar and busbar.The following low capacity power of 500A, the illumination two buss lines that adopt above structure to produce have following drawback:
1, because the busbar plane is close, and the electromagnetic induction area is big, the inductance galvanomagnetic effect of formation causes reactance, impedance big, and reactive loss is high;
2, because the thickness of busbar of having drawn design limit of branched line has just been fixed surface area when confirming sectional area, the busbar surface area can not arbitrarily increase, and has limited the utilization of electric current skin effect;
3, intensive, air type bus duct mainly is applicable to higher capacity link, and when same structure was used for the low capacity circuit, overall volume was bigger, complex structure, and assembling inconvenience, the every ampere per meter (A/m) material cost of product occupies the artificial manufacturing cost of high, every ampere per meter (A/m) and occupies high;
4,Cost performance is lower than power cable, no market competition advantage.
Summary of the invention
Goal of the invention: a kind of material is provided
BecomeThis has the degree of protection of higher water proof and dust proof with artificial cheap for manufacturing cost, Low ESR, low magnetic, the low-carbon economy type low capacity bus duct product of high performance-price ratio.
Technical scheme: the low capacity power and lighting bus duct of the utility model is made up of insulation separation trough, busbar, insulation pressing, metal shell.
The insulation separation trough is made up of base plate, side plate, dividing plate.Its median septum separation trough that will insulate is separated into two or more separate slots.Can be divided into single-phase or three-phase according to the concrete needs of power supply, two grooves, three-flute, four grooves, five grooves are set.
Insulation pressing is equipped with according to specification, the quantity of the separate slot of insulation separation trough.
Insulation separation trough and insulation pressing are combined into insulator, and busbar is positioned at insulation separation trough inside bottom, is flat transverse and arranges.The dividing plate of insulation separation trough separates busbar safety.The height of the demarcation strip during insulation is separated must satisfy electric clearance and creepage requirement.Insulation pressing is arranged along the segmentation of insulation separation trough length direction, busbar is pressed on the bottom of separation trough.Metal shell is encapsulated in inside with insulator and busbar, makes whole bus form an integral body, and the shell of bus can be used as nonfused earthed conductor.Bus duct can be provided with lead outlet according to distribution branch needs.
Beneficial effect: this bus duct has adopted the fixedly method that encapsulates of busbar, metal shell of insulation separation trough and insulation pressing, makes that product has that the cost of material is low, assembling is convenient, production efficiency is high, water proof and dust proof, safe and reliable characteristics.The method that busbar is laterally placed, side is close is compared with the structure that busbar intensive, the air bus is vertically placed, the plane is close; The electromagnetic induction area is little, has low magnetic, low anti-characteristic, can reduce reactance and impedance; Improve the line electricity flow, reduce line loss.And because the change of structural design can reduce busbar thickness, increase width, long-pending with this enlarged surface, maximum using the skin effect of ammeter area the busbar ampacity is improved, maximum carrying capacity can reach 5A/mm
