Abstract
The utility model relates to a copper core enclosed busbar. The enclosed busbar comprises a shield shell, an insulator and a busbar; the busbar is arranged in the shield shell by the insulator, the busbar is a copper core busbar; the utility model provides an enclosed busbar which has the advantages of large current-carrying capacity, good heat dissipation, small volume, and needing no transition of copper to aluminum.
Description
Technical field
The utility model relates to a kind of copper core enclosed busbar.
Background technology
The power of power plant main force motor generally about 300,000 kilowatts, have in addition reach 1,000,000 kilowatts.Power of motor is 300,000 kilowatt hours, and output current reaches the training of 1 Wan An, and power of motor is 900,000 kilowatt hours, and electric current can be trained near 3 Wan An.This electric current can produce high-intensity magnetic field, and for avoiding the magnetic field effect of big electric current, traditional bus utilizes the principle of electromagnetic shielding, and bus is arranged in the shielding case, is enclosed busbar, and the strong magnetic field that produces when the current delivery with blocking-up is to the influence of peripheral facility.Simultaneously, for fear of phase fault takes place, all be to adopt the phase-splitting enclosed busbar both at home and abroad.Traditional enclosed busbar is made of aluminum, by insulator tubular aluminium core bus is fixed in the shielding case.Because the resistivity of aluminium itself is higher, ampacity is low, can increase the electric energy transmitting loss, and volume is also big, and consumptive material is also many.Because what motor and Transformer Winding adopted all is copper conductors, the contact of copper aluminium also can produce the battery corrosion phenomenon, needs copper-aluminium transition.Adopting the tubular aluminium conductor to have many drawbacks for the throat of large power plant, is extremely irrational.
The utility model content
The above-mentioned technical problem that the utility model exists for the enclosed busbar that solves in the background technology, and provide that a kind of ampacity is big, thermal diffusivity good, volume is little and do not need the enclosed busbar of copper-aluminium transition.
Technical solution of the present utility model is: the utility model is a kind of enclosed busbar, and its special character is: this enclosed busbar comprises shielding case, insulator and bus, and bus is arranged in the shielding case by insulator, and bus is a copper core bus.
Above-mentioned copper core bus is that perforate is tubular or special-shaped.
Above-mentioned abnormity is tubular, the I-shaped or flute profile combination of size with one heart.
The tubular copper core of above-mentioned concentric size bus curves tubular by three buses, is arranged on the tubular bus by connecting plate.
The seam crossing of above-mentioned three tubular buses is provided with pad.
Above-mentioned insulator is an insulator.
Above-mentioned shielding case is the aluminum or aluminum alloy material.
Bus of the present utility model adopts copper core bus, since copper cut the big (during same cross section of flow-rate ratio aluminium, the amount of damming of copper is 1.3 times of the amount of damming of aluminium), electric conductivity and heat dispersion be all good than aluminium, like this, under the identical situation of power, the copper core of same sectional area is littler than aluminium core electrical loss, and thermal diffusivity is good, volume is little, and consumptive material is few.And the shape of the utility model copper core bus can adopt perforate tubular or special-shaped, has increased the surface area of copper core, has further improved the heat dispersion of copper core bus; Simultaneously because enclosed busbar of the present utility model, bus adopts copper core bus, and is identical with the material of the copper cash of motor and transformer employing itself, do not have the problem of copper-aluminium transition.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model abnormity copper core bus.
Embodiment
Referring to Fig. 1, the utility model comprises shielding case 1, insulator 2 and bus 3, and bus 3 is arranged in the shielding case 1 by insulator 2.Bus 3 is a copper core bus.Copper core bus 3 can be that perforate is tubular or special-shaped, and abnormity is tubular, the I-shaped or flute profile combination of size with one heart.
Referring to Fig. 2, this abnormity copper core bus curves tubular by three buses 3, is welded on the tubular bus 5 by connecting plate 6.Constitute the little barrel shape of big jacket casing.The seam crossing of big tube welds a small amount of pad 7, make three buses 3 constitute big tube and be shaped, the slit 4 of not welding part be for ventilation and heat set.
