Abstract
The utility model relates to a split composite screening insulated copper and aluminum tube bus. The outside of an inner core consisting of two semi-circular copper and aluminum tubes, or more than three sector copper and aluminum tubes with same sections is provided with a semiconductive layer, a composite screening insulated layer, a semiconductive layer, a protective sleeve and an earthing protective layer; and an insulating layer is arranged at the jointed part of the semi-circular or sector copper and aluminum tubes. The split composite screening insulated copper and aluminum tube bus can uniformly distribute the carrying capacity of the bus through a plurality of split conductors formed by the semi-circular tubes or a plurality of sector tubes, which enlarges the carrying area of the conductors, reduces the carrying capacity of single split conductor, and reduces temperature rise and linear reactance, thereby reaching the purposes of meeting the requirements of large current carrying capacity and reducing tail end voltage drop. The split composite screening insulated copper and aluminum tube bus can reach the power transmission and distribution requirements of a power transmission and distribution system. The tail end voltage drop of the split composite screening insulated copper and aluminum tube bus is greatly lower than a designed power reference value. Hollow conductors are adopted, which can save materials and energies. The split composite screening insulated copper and aluminum tube bus not only can solve large current carrying capacity, but also can solve the problem that the voltage drop value can meet the design and using requirements during long distance transmission.
Description
Technical field
The utility model relates to a kind of division formula composite shielding insulated copper, aluminum tube bus.
Background technology
At present, electric current surpasses the big electric current field of power transmission of 1250A both at home and abroad, adopts insulating tube type busbar to substitute traditional rectangular bus bar and cable mostly.Existing insulating tube type busbar, its inner core are holistic copper, aluminum pipe, and copper, aluminum pipe have semi-conductive layer 2, composite shielding insulating barrier 3, semi-conductive layer 2, sheath and ground protection layer 4 successively.Though it can make full use of electric current kelvin effect advantage, ampacity is big, and because of being relies on individual tubes bus conduction, surface of conductors is long-pending to be restricted with sectional area, and ampacity is big, self reactance is high.Be subjected to the influence of the big and self reactance of its ampacity, temperature rise.Especially remote when carrying big electric current, temperature rise, the bus starting voltage is fallen greatly, and its value often exceeds the distribution system set point, and these have all restricted the application and the development of insulated tube bus in more areas.
Summary of the invention
The purpose of this utility model is at above-mentioned present situation, aims to provide a kind ofly can solve big electric current current-carrying, can solve long distance again and carry voltage drop value to satisfy division formula composite shielding insulated copper, the aluminum tube bus of design and use requirement problem.
The implementation of the utility model purpose is, division formula composite shielding insulated copper, aluminum tube bus, inner core has semi-conductive layer, composite shielding insulating barrier, semi-conductive layer, sheath and ground protection layer outward successively, inner core is made up of fan-shaped copper, the aluminum pipe of two semicircle copper, aluminum pipe or three above same cross-sectional, at the joint of semicircle or fan-shaped copper, aluminum pipe insulating barrier is arranged.
Inner core of the present utility model is made up of two semicircle copper, aluminum pipe or fan-shaped copper, aluminum pipe more than three, can be by many divided conductors of semicircular pipe or the formation of a plurality of sector tube, the divided conductor joint has insulating barrier, the bus ampacity is evenly distributed on each divided conductor, increased the area of conductor current-carrying, reduce the ampacity of single divided conductor, reduced temperature rise, reduced line reactance, thereby reached the purpose that satisfies the requirement of big electric current current-carrying and reduce terminal pressure drop.
After testing the test, the utility model in the transmission line of 10kv, 4000A, voltage drop＜0.08V/m, temperature rise≤45K.
The utility model can reach the conveying electricity requirement of electrical power trans mission/distribution system, and its terminal voltage falls and is significantly less than the accurate value of Electric Design.Owing to be hollow conductor, both effectively saved metals resources, farthest saved the energy again; Its outer surface is sheath and ground protection layer, and safety is tangible, and spatial placement has effectively been saved in the charged safe distance requirement that has solved the open type conductor, has alleviated the layout difficulty of bus-bar system.
The utility model can solve big electric current current-carrying, can solve long distance again and carry voltage drop value to satisfy the design and use requirement.
