Abstract
The utility model relates to an air-type insulating bus duct. The sectional materials of upper and lower cover plates are clamped into ethylene-propylene-diene monomer with high-level temperature resistance and good insulating property. The phases of conducting busbars of four phase lines A, B, C, and N are separately disposed in cavities of the bus duct, thereby enabling each conductor of a bus to contact with the upper and lower cover plates. Therefore, heat can be transmitted to the surfaces of the cover plates quickly through employing the principle of heat transfer during the operation of the bus, thereby guaranteeing the safety factor of the operation of the bus better.
Description
Technical field
The utility model relates to the bus duct product in public place power transmission and transforming equipment, is applied in power distribution network, is applicable to the equipment power transmission and distribution of each big-and-middle-sized industry and commerce building, workshop, warehouse, airport, market, enterprise.
Background technology
Along with the high speed development of national economy, promote market sharply to rise to the demand of bus duct.Mostly on market take compact bus bar as main, although intensive insulation bus slot from security performance, current capacity is large, have good energy-saving effect from machining angle, manufacture craft more complicated; Equipment investment costliness, workman must be through professional training; As everyone knows, in bus duct, copper conductor has occupied the more than 70% of cost.Within 2003, rise, because copper material significantly appreciates, cause bus duct cost significantly to rise, so compact bus bar is extremely applicable to the transmission of high-power electric current; Although relatively the bus of small dimension is as selected intensive isolated bus better performances for electric current, bus cost is relatively high, can not realize the object of " this falls in upgrading ".
Summary of the invention
Technical problem to be solved in the utility model is, a kind of air type insulating bus duct is provided, and requires with low costly, and reliable in structure, can reach simple, easy for installation, the economical and practical object of technique.
The technical scheme that solves its technical problem employing is: design a kind of air type insulating bus duct, snap at upper and lower cover plates section bar that temperature resistant grade is high, the ethylene propylene diene rubber of good insulation preformance, separate and be placed in bus duct cavity mutually every tetra-phase line conductive bus bars of ABCN, every conductor of bus is contacted with upper and lower cover plates.Thereby reach bus in the time of operation, the principle of utilizing heat to transmit, can be delivered to heat rapidly cover plate face, better guarantee the coefficient of safety of bus operation.
Air type insulating bus duct of the present utility model, include upper cover plate, left plate, electro-insulating rubber part, bus conductive bus bar, right plate and lower cover, upper cover plate, lower cover inner surface have wave shape groove, electro-insulating rubber part is ethylene propylene diene rubber material, same compression molding is wave shape groove shape, be installed in upper cover plate, lower cover inner surface wave shape groove, bus conductive bus bar is plugged in electro-insulating rubber part groove, and left plate, right plate are fixedly installed between upper cover plate, lower cover.
Air type insulating bus duct of the present utility model, more than described electro-insulating rubber part exposes outside bus two ends 15mm, conductor part in bus duct inside does not drape over one's shoulders shoe insulating material, when bus duct load running, can accelerate dissipation of heat, and arrive bus duct side cover plate position by air bamboo telegraph, form heat exchange with bus duct cool exterior air, improved pyroconductivity, guaranteed the coefficient of safety of bus operation.
Air type insulating bus duct of the present utility model, with low cost, reliable in structure, technique is simple, easy for installation, and coefficient of safety is high.
Accompanying drawing explanation
Fig. 1 is air type insulating bus duct planar structure schematic diagram of the present utility model.
Below in conjunction with accompanying drawing, the utility model is further illustrated.
In figure: 1, upper cover plate 2, left plate 3, electro-insulating rubber part 4, bus conductive bus bar 5, right plate 7, lower cover
Embodiment
As shown in the figure, air type insulating bus duct of the present utility model, include upper cover plate 1, left plate 2, electro-insulating rubber part 3, bus conductive bus bar 4, right plate 5 and lower cover 7, upper cover plate 1, lower cover 7 inner surfaces have wave shape groove, electro-insulating rubber part 3 is ethylene propylene diene rubber material, same compression molding is wave shape groove shape, be installed in upper cover plate 1, lower cover 7 inner surface wave shape grooves, bus conductive bus bar 4 is plugged in electro-insulating rubber part groove, and left plate 2, right plate 5 are fixedly installed between upper cover plate 1, lower cover 7.
Air type insulating bus duct of the present utility model, more than described electro-insulating rubber part 3 exposes outside bus conductive bus bar 4 two ends 15mm, conductor part in bus duct inside does not drape over one's shoulders shoe insulating material, when bus duct load running, can accelerate dissipation of heat, and arrive bus duct side cover plate position by air bamboo telegraph, form heat exchange with bus duct cool exterior air, improved pyroconductivity, guaranteed the coefficient of safety of bus operation.
