Description
Technical field
The utility model relates to transmission facility technical field, specifically a kind of bus duct.
Background technology
Along with the develop rapidly in city, skyscraper gets more and more, building power load sharply increases thereupon, and original electric wire is because its capacity is little, branch is inconvenient, be not easy to the reasons such as boundling management, and progressively, branch large by capacity and boundling manage bus duct easily and replace.Bus duct is widely used in the key project such as electric power conveying route and fire-fighting emergent equipment main line of fire control equipment, such as, in the important engineerings such as commercial square, subway, airport, office building, entertainment place, communal facility.Therefore, the safety and stability performance of bus duct product is most important, and the requirement of China to bus duct product safety performance is also more and more higher, requires the electric power conveying backbone continued power within the fire fighting time guaranteeing building ' s fire.
Along with the fast development of China's power transmission and distribution cause, bus duct product is widely applied, and has become every engineering at the requisite part in power transmission and distribution field, mainly as power supplying and distributing equipment novel in industrial and mineral, enterprises and institutions and skyscraper.The bus duct of carrying spigots, by connection-peg case or jack switch case, can draw power supply along separate routes easily.Bus duct has the advantages such as volume is little, compact conformation, transmission current are large, easy to maintenance.The installation of bus duct directly can receive low-voltage distribution cabinet from transformer, also can directly receive distribution system as distributiong main circuit from low-voltage cabinet.
China's electric power industry development is rapid, drive increasing substantially of copper, in bus duct, copper conductor cost accounts for more than 70% of total cost, and copper material price goes up soon in recent years, to bus duct, manufacturing enterprise brings immense pressure, force enterprise to have to reduce cross-sectional area of conductor to deal with, not only reduce the security performance of bus duct thus, and increase energy consumption.The rich aluminium of the poor copper of China, copper-aluminum composite conductor fundamental performance parameter is close to copper conductor, but can reduce costs, bus duct is manufactured by copper-aluminum composite conductor, not only can significantly reduce costs, and the dependence of bus duct to copper material in short supply can be alleviated, and use lower cost increasing section, larger energy-saving effect can be obtained.
Utility model content
The technical problems to be solved in the utility model is for Problems existing in background technology, provides a kind of bus duct.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of bus duct, comprise housing, described housing comprises upper plate, first side plate, second side plate and lower plate, the accommodating cavity holding conductive bus bar assembly is provided with in described housing, flame-resistant resin pour mass is filled with in described cavity, described upper plate, first side plate, second side plate and lower plate are by one-body molded formation isosceles trapezoid component, at described upper plate, first side plate, medial surface in the accommodating cavity that second side plate and lower plate are formed is provided with wavy striped, described conductive bus bar assembly is Copper-Aluminum compound bus, and be triangularly arranged setting in the cavities, the cross section ovalize of described conductive bus bar assembly.
Further, the sidewall in the cavity in described housing is provided with insulating coating.
Further, be respectively equipped with in the outside of described first side plate, the second side plate that length is interlocked, the fin of parallel longitudinal arrangement.
Adopt a kind of bus duct of the present utility model, because described housing is integrated member, in described housing, establish Packed cavity, flame-resistant resin pour mass is filled with in described cavity, described conductive bus bar assembly is Copper-Aluminum compound bus, and its antioxygenic property is strong, and contact resistance is little, identical with copper conductor, lightweight, cost is low, in addition, sidewall in cavity in described housing is provided with insulating coating, heat conductivility is improved greatly.Be respectively equipped with in the outside of described first side plate, the second side plate that length is interlocked, the fin of parallel longitudinal arrangement, be conducive to the flowing of gas between fin, further increase the radiating effect of bus.Have structure simple, Low ESR, low pressure drop, low energy consumption, low cost, dependability is high, ensures the safety of electric power system, is with a wide range of applications.
