The combined bus duct has a simple structure, is convenient to install and is used for installing copper buses.
Description
Technical field
The utility model relates to a kind of bus duct, more particularly, relates in particular to a kind of Combined bus groove for copper busbar is installed.
Background technology
The auxiliary equipment of power supplying and distributing equipment in industrial and mineral, enterprises and institutions and skyscraper; the general cable that adopts connects power transmission and distribution before 2000; limitation due to cable; enclosed bus duct (abbreviation bus duct) product progressively occurred, this product is mainly the bus-bar system that protecting sheathing, busbar, insulating material and relevant annex form by metallic plate (steel plate or aluminium sheet).It can be made into the splicing type enclosed busbar that is provided with the grafting junction box every a segment distance, in the middle of also can be made into not with the feeding type enclosed bus of junction box.In the electric power system of skyscraper, power and illuminating line often divide and are arranged, bus duct as power supply backbone in electric shaft along wall at right angle setting one time or many times.The bus duct product is also along with distribution technique develops by air type insulation plug-board bus bar groove, develops into intensive insulation plug-board bus bar groove and high strength plug-board bus bar groove.
Adopt plug type bus duct and cable to compare advantage as follows:
(1) the bus duct tap is convenient: the mode that the plug type bus duct utilization is pegged graft is switched to branch line to the power supply of backbone, so tap is very convenient.Its shortcoming of prefabricated branch cable is to customize to factory; Its branch connected mode adopts " C " type anchor ear of opening, and the time one is of a specified duration, and clamping force is not enough, adds the expensive of each branch's head, thus prefabricated branch cable application surface is wideless so far.Any one flooring need to be cut off the electricity supply in addition, and bus duct need not cut off the power supply, as long as in the situation that zero load, the jack box that takes off bus duct gets final product.But cut off the branch power supply of prefabricated branch cable, in the situation that charged operation is very dangerous.
(2) bus duct overload capacity is strong: bus duct overload capacity is strong, the insulating material working temperature that depends on its use is high, it is the material of 105 ℃ that insulating material that bus duct is used adopts working temperature, and radiation crosslinking flame-retardant take-up strap (PER) and the crosslinking with radiation now having developed working temperature and be more than 140 ℃ gather the hydrocarbon heat-shrinkable tube.And the cable normal phase working temperature of insulating material used is generally 95 ℃ and 105 ℃, so the overload capacity of bus duct is far longer than cable.
(3) bus duct can prevent from transshipping and catch fire: the insulating barrier of common cable and crust can burn, flame retardant cable also can burn under flame, does not only just burn after flame leaves, and fire-resisting cable can not burn, but expensive, only have the power supply of the inaccurate power failures such as fire-fighting just to use fire-resisting cable.The bus duct shell is steel, can not burn, even the insulating material of copper bar burns, flare can not channel to outside bus duct yet.
(4) bus duct perfect heat-dissipating: the insulating material of cable (core insulation and crust insulation) is insulating material, is again heat-barrier material, so power cable allows at most to lay 2 layers when laying in crane span structure, and its reason is to consider heat radiation.Concentration bus duct phase and phase and all being close together with shell is therefore can bear larger electronic stress and thermal stress.And the heat that busbar can be produced distributes rapidly, and ampacity is large.Joint is fastening with insulated bolt, adopts simultaneously the dual link copper bar to connect, and has effectively increased joint contact surfaces long-pending, greatly reduces the joint area temperature rise.
(5) bus duct has good Short Circuit withstand performance: due to the protection with aluminium (or weak magnetic steel plate) shell; can effectively weaken the structure heating that eddy current or circulation cause, reduce the bus duct skin temperature, reduce electric energy loss; improve ampacity, alleviate electric power.
(6) bus duct is easy to maintenance: bus duct must be safeguarded hardly, regular maintenance is normally measured the temperature rise of shell and punching bolt, the joint temperature rise of inlet wire case etc., if the punching bolt adopts 4.8 grades, need regularly fastening, if adopt the high strength bolt of 8.8 grades needn't be regularly firm.
The utility model content
The purpose of this utility model is to provide a kind of Combined bus groove simple in structure, easy for installation.
The technical solution of the utility model is achieved in that a kind of Combined bus groove, comprise base plate, two blocks of side plates and cover plate, two blocks of side plates are arranged on respectively base plate both sides along its length, the relative medial surface of wherein said two blocks of side plates is respectively equipped with L shaped location-plate along its length, described L shaped location-plate coordinates with corresponding side plate and forms location notch, and the two ends of described base plate are plugged on respectively in location notch; Described base plate, two blocks of side plates and cover plate coordinate and form the cavity that bus is installed.
In above-mentioned Combined bus groove, rivet with two blocks of side plates respectively at the two ends of described cover plate.
In above-mentioned Combined bus groove, the outer surface of described base plate and cover plate is distributed with heat-dissipating fin.
After the utility model adopts said structure, by L shaped location-plate is set on side plate, L shaped location-plate is coordinated with side plate form location notch, thereby can being pegged graft easily, base plate is fixed between two blocks of side plates, both convenient connections, the riveting work of two blocks of side plates and base plate has been reduced in the occupation of land space in the time of also can reducing carrying, can directly the copper bar that bandages be placed in mounting groove, subsequently cover plate be covered and rivets and get final product.The utlity model has simple in structure, installation and convenient transportation, little advantage takes up room.
Description of drawings
The utility model is described in further detail below in conjunction with the embodiment in accompanying drawing, but do not consist of any restriction of the present utility model.
Fig. 1 is structural representation of the present utility model.
In figure: base plate 1, side plate 2, L shaped location-plate 2a, cover plate 3, heat-dissipating fin 4.
Embodiment
Consult shown in Figure 1, a kind of Combined bus groove of the present utility model, comprise base plate 1, two blocks of side plates 2 and cover plate 3, two blocks of side plates 2 are arranged on respectively base plate 1 both sides along its length, the relative medial surface of described two blocks of side plates 2 is respectively equipped with L shaped location-plate 2a along its length, described L shaped location-plate 2a coordinates with corresponding side plate 2 and forms location notchs, and the two ends of described base plate 1 are plugged on respectively in location notch; Described base plate 1, two blocks of side plates 2 and cover plate 3 coordinate and form the cavity that buses are installed.Rivet with two blocks of side plates 2 respectively at the two ends of described cover plate 3.Further, be distributed with heat-dissipating fin 4 at the outer surface of base plate 1 and cover plate 3, can be used for improving like this radiating efficiency, guarantee the normal operation of circuit.
During use, at first base plate 1 correspondence is plugged in the location notch of two blocks of side plates 2, form the mounting groove of bus, after the bus installation, then cover plate 3 is covered on bus, by rivet, cover plate 3 is fixedly connected with side plate 2 simultaneously, namely complete installment work, compare original base plate and cover plate and side plate and rivet respectively, both reduced the use of rivet, improved again the efficient of installing; Compare with the integrated structure of original base plate and side plate, reduced space hold in transit, install same very convenient quick.
