Description
Technical field
The utility model relates to low pressure electric line bus duct mains system, belongs to the technical field that the power bus-bar groove is made.
Background technology
In order to satisfy industry, the needs of the high-current low-voltage transmission line during civil engineering is built, the bus duct mains system is all adopted in the power distribution design, continuing to increase along with the electric line capacity in recent years, the bus duct mains system has been widely applied in the engineering, the bus duct product structure design from the air insulation type to intensive insulated type, from the outer cover of steel plate to the aluminum alloy casing, shell from the shell of slab construction to the heat sink strip structure, degree of protection is from IP40 to IP66, run through the evolution of whole industry, the most important technical performance index of bus duct is the size of the line loss that reactance produced of conductor temperature rise and electromagnetic induction.Electric current produces heat energy because of resistance, because bus duct is the big electric current transmission line that conductor is concentrated, so conductor is also concentrated especially because of the thermal effect that resistance produces, the radiating effect quality of bus duct shell is directly connected to manufacturing, cost of investment and the user's of the technical performance index of entire product and enterprise safe handling.
The air insulation type bus duct of the steel plate forming shell that adopts on the past market is very poor in heat radiation, the sectional area of its conductor is selected generally all long-pending greater than intensive insulated type bus duct cross-sectional area of conductor, and the temperature rise of conductor also is higher than the temperature rise of concentration bus duct conductor, is least economic a kind of product.This product will be substituted by intensive insulated type bus duct product gradually.In order to improve the heat dispersion of intensive isolated bus groove, once researched and developed aluminum alloy casing band heat sink strip concentration bus duct product abroad, but this product also has following deficiency:
1, shell is limited to structure, and radiating surface can not utilize to greatest extent;
2, complex process, high material consumption, production efficiency is low;
3, material cost causes the manufacturing cost height.
Summary of the invention
Goal of the invention: goal of the invention of the present utility model provides a kind of low resistance, low reactance, line loss is low, consumptive material is few high-efficiency heat radiation structure low-cost energy-saving bus duct.
Technical scheme: energy-saving bus slot of the present utility model serves as overall the support with two symmetrically arranged bus side plates, cover plates, lateral surface at two bus side plates is provided with the side plate fin, cover plate is positioned at the lateral surface of two bus side plate flangings, and by securing member bus side plate and cover plate are connected into an integral body, space that cross section is a rectangle of formation in the zone that bus side plate and cover plate are enclosed.Medial surface at the bus side plate is provided with insulating barrier, and bus-bars conductor is between insulating barrier.
The fin of the biside plate outside of this bus duct adopts the radiator structure of concavo-convex corrugated sheet, concavo-convex corrugation radiator structure extends at interval or does not extend at interval along the length direction of biside plate outside, the biside plate plane (inboard) of bus shell closely contacts with the bus-bars conductor plane that is coating insulating barrier, side plate by bus shell is connected with the cover plate assembling, is assembled into bus duct.
Beneficial effect: energy-saving bus slot of the present utility model is owing to adopt the radiator structure of concavo-convex corrugated sheet that total area of dissipation of side plate has been increased more than 2.3 times on the original basis on the biside plate of the shell of bus duct, compare increase about 70% with the radiating surface of aluminum alloy heat sink bus side plate, infer by theoretical, the bus duct of same current class adopts same cross-sectional area of conductor long-pending, under equal electric current transport condition, because of thermal diffusivity good, energy-saving bus slot can reduce the conductor temperature rise, reduce line loss, saves energy, otherwise, the bus duct of same current class under equal electric current transport condition, is reaching under the standard code temperature rise requirement equally, energy-saving bus slot can reduce to use the sectional area of conductor, save the material of using of conductor, reduced the cost of product, saved metallic conductor resource consumption, take into account as both, both can be energy-conservation, again can material-saving, meet the low-carbon (LC) product requirement.And, make biside plate increase intensity, thereby increased the bus duct integral intensity because radiator structure has adopted corrugated sheet.
