Abstract
The utility model relates to an intensive bus duct. Each bus duct unit comprises side plates, cover plates, end plates, a current-carrying conductor and insulation cushion blocks. One side surface of each side plate is provided with clamping groove plates in a mirror symmetry mode in the vertical direction. Heat dissipation tooth sheets are uniformly distributed on the portion, between the two clamping groove plates, of each side plate at intervals. The two side plates are arranged in the mirror symmetry mode and the current-carrying conductor is installed between the other side surfaces. The insulation cushion blocks are positioned and fixedly installed on upper and lower ends of the current-carrying conductor between the two side plates. The upper and lower insulation cushion blocks are positioned and fixedly installed through using standard bolts. A fixed-installing end plate is welded between the two clamping groove plates of each side plate. Upper and lower ends of the two side plates are packaged with cover plates. The structure of the bus duct of the utility model is simple; assembling is rapid; cost is low and usage is reliable. A shell heat dissipation area is large and a heat dissipation effect is good. Power supply system safety can be guaranteed maximumly. The bus duct is especially suitable for a single-row structure-intensive bus duct structure below 2500A and possesses a wide application prospect.
Description
Technical field
The utility model belongs to power domain, relates to the bus duct in controller switching equipment, especially a kind of concentration bus duct.
Background technology
China's electric power industry development is rapid, market is constantly competed, cause pernicious unordered the bringing down prices of a lot of enterprises, everybody is fierce to make complete enterprise's volume cost atrophy day by day, especially bus duct market, although also uncomplicated as structure and the processing technology of concentration bus duct itself, but want to enhance productivity, and then cost-saving also non-easy thing, because of the industry domestic demand want a kind of high-performance, highly reliable, assemble concentration bus duct structure easily, from manufacturing angle, greatly reduce cost of labor.If increase corresponding area of dissipation on shell simultaneously, can make the electric conductivity of whole concentration bus duct be further enhanced, reduce energy waste.
By retrieval, not yet find the patent documentation relevant to present patent application.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides a kind of assembling convenient, the concentration bus duct of good looking appearance, various performance index excellences.
The purpose of this utility model is achieved in that
A kind of concentration bus duct, each bus duct unit comprises side plate, cover plate, end plate and current－carrying conductor, cross-over block, side plate adopts the almag section bar of polymorphic structure, the upper and lower mirror image symmetry in one side is shaped with clamping groove plate, on the side plate between two clamping groove plates, uniform interval is shaped with heat radiation gear piece, two side plate mirror images be symmetrical arranged and its another side between current－carrying conductor is installed, on this current－carrying conductor, all at its outer surface insulating barrier, be wound around polyester film; Current－carrying conductor upper/lower terminal between two side plates is all located and is fixedly mounted with cross-over block, and these upper and lower two cross-over blocks all adopt standard bolt to position and are fixedly mounted with; Between two clamping groove plates of every side plate, welding is fixedly mounted with end plate, at the upper/lower terminal of two side plates, is packaged with cover plate.
And symmetrical all downward bendings of the two side ends mirror image of described cover plate, and be shaped with stopper in the end of bending, so that the bending part setting-in of cover plate enters outside two clamping groove plates of side plate, and adopt the stopper of cover plate to be located.
Advantage of the present utility model and good effect are:
1, the shell of this bus duct consists of almag section bar, is divided into side plate and cover plate, uniform fin and the notch of being designed with on side plate, and this design has increased area of dissipation, has improved ampacity, has also strengthened shell rigidity.Sound construction good looking appearance, without visual screw, good looking appearance, it is convenient to install, and has improved shell protection grade.
2, bus duct conductor dbus of the present utility model is crossed polyester film and is wound around protection close-packed arrays; as the DMC unsaturated polyester (UP) of insulating material and epoxy resin etc., all there is good insulation, moisture resistance, resistance to chemical corrosion; material property is stable, nontoxic, light-weight environment-friendly, and price is suitable.
3, the utility model is more firm through fixing of side plate clamping and screw, dynamic thermal stability is better, safer, the cover plate of shell is fixed by custom-designed draw-in groove, connects closely, has saved space, the heat conductivity increasing, due on shell without any perforate, aqueous vapor dust cannot enter, and has naturally also just improved degree of protection.
4, the utility model is simple in structure, and assembling is quick, low cost, use reliably, shell area of dissipation is large, good heat dissipation effect, can guarantee to greatest extent the safety of electric power system, be particularly suitable for the following single row configuration concentration bus duct of 2500A structure, be with a wide range of applications.
