The easy-assembly bus groove is simple in structure and convenient to install and is applied to installation of cables.
Description
Technical field
The utility model relates to a kind of bus duct, more particularly, relates in particular to a kind of easy-to-assemble bus duct.
Background technology
The auxiliary equipment of power supplying and distributing equipment in industrial and mineral, enterprises and institutions and the skyscraper; The general cable that adopts connects power transmission and distribution before 2000; Because the limitation of cable; Closed bus duct (abbreviation bus duct) product progressively occurred, this product is the bus-bar system that protecting sheathing, busbar, insulating material and relevant annex are formed by metallic plate (steel plate or aluminium sheet) mainly.It can be made into and every is provided with the grafting type enclosed busbar of grafting junction box at a distance from a segment distance, also can be made into the centre not with the closed bus of feed type of junction box.In the electric power system of skyscraper, power and illuminating line often divide and are arranged, and bus duct is installed one time or many times along wall is vertical in electric shaft as power supply backbone.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.
It is following to adopt plug type bus duct and cable to compare advantage:
(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 be cut off the electricity supply in addition, and bus duct need not cut off the power supply, as long as under the situation of zero load, the jack box that takes off bus duct gets final product.But cut off the branch power supply of prefabricated branch cable, operation is very dangerous under charged situation.
(2) bus duct overload capacity is strong: bus duct overload capacity is strong; The insulating material working temperature that depends on its usefulness is high; It is 105 ℃ material that the insulating material that bus duct uses adopts working temperature, and radiation crosslinking flame-retardant take-up strap (PER) and the crosslinking with radiation having developed working temperature at present and be more than 140 ℃ gather the hydrocarbon heat-shrinkable tube.And the used normal phase working temperature of insulating material of cable is generally 95 ℃ and 105 ℃, so the overload capacity of bus duct is far longer than cable.
(3) bus duct can prevent to transship and catch fire: the insulating barrier of common cable and crust can burn; Flame retardant cable also can burn under flame, only after flame leaves, does not just burn, and fire-resisting cable can not burn; But cost an arm and a leg, have only the power supply of inaccurate power failures such as fire-fighting just to use fire-resisting cable.The bus duct shell is a steel, can not burn, even the insulating material of copper bar burns, flare can not scurried the bus duct outside yet.
(4) bus duct perfect heat-dissipating: the insulating material of cable (core insulation and crust insulation) is an insulating material, is again heat-barrier material, so power cable allows to lay 2 layers at most when in crane span structure, laying, and its reason is to consider heat radiation.Concentration bus duct phase and phase and all be close together with shell is so can bear bigger electronic stress and thermal stress.And can the heat that busbar produced be distributed rapidly, ampacity is big.Joint is fastening with insulated bolt, adopts the dual link copper bar to connect simultaneously, and it is long-pending effectively to have increased joint contact surfaces, greatly reduces the joint area temperature rise.
(5) bus duct has good Short Circuit withstand performance: owing to have the protection of aluminium (or weak magnetic steel plate) shell, can weaken the structure heating that eddy current or circulation cause effectively, 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.; The punching bolt is if adopt 4.8 grades, then need regularly fastening, if adopt 8.8 grades the high strength bolt then needn't be regularly firm.
The utility model content
The purpose of the utility model is the deficiency to above-mentioned prior art, and a kind of easy-to-assemble bus duct simple in structure, easy for installation is provided.
The technical scheme of the utility model is achieved in that a kind of easy-to-assemble bus duct, comprises base plate, two blocks of side plates and cover plate; Two blocks of side plates are arranged on the base plate both sides respectively along its length, wherein, described base plate and two overall structures that side plate is formed in one, base plate cooperates the formation mounting groove with side plate, and described cover plate cooperates formation hermetic cavity body with mounting groove.
In the above-mentioned easy-to-assemble bus duct, described mounting groove and cover plate riveted joint.
In the above-mentioned easy-to-assemble bus duct, the outer surface of described base plate and cover plate is distributed with heat-dissipating fin.
After the utility model adopts said structure; Originally independently base plate and side plate were designed to integrated overall structure separately through inciting somebody to action; Reduced the riveting work of two blocks of side plates and base plate, can directly the copper bar that bandages be placed in the mounting groove, covered cover plate and rivet subsequently and get final product.The utility model compared with prior art has following advantage:
(1) improves degree of protection.The degree of protection of this type of concentration bus duct requires to reach IP54; Stipulate according to GB4208-2008; The implication of IP54 is that the examination tool that prevents diameter 1.0mm must not get in the shell, and simultaneously to the shell all directions no adverse effect that dabbles, so this product is high to the requirement of degree of protection.The three-lane road straight forming has then well reduced the connection of rivet, reduces the slit and occurs, and has improved degree of protection;
(2) increase work efficiency.Two cover plates and a side plate are adopted one-time formed method, reduced more workload, increase work efficiency more than 35% in operations such as aluminium section bar sawing, aluminium section bar welding, aluminium section bar punching, aluminium section bar assemblings;
(3) save production cost.Owing to adopt one-shot forming, reduced the amount of punch press punching, also reduced the connection of rivet, can practice thrift many costs of labor, cost of supplementary product, the loss of less electrical energy etc.
Description of drawings
Below in conjunction with the embodiment in the accompanying drawing the utility model is done further to specify, but do not constitute any restriction the utility model.
Fig. 1 is the structural representation of the utility model.
Among the figure: base plate 1, side plate 2, cover plate 3, heat-dissipating fin 4.
Embodiment
Consult shown in Figure 1ly, a kind of easy-to-assemble bus duct of the utility model comprises base plate 1, two side plates 2 and cover plates 3; Two blocks of side plates 2 are arranged on base plate 1 both sides respectively along its length; Base plate 1 and two overall structures that side plate 2 is formed in one; This structure can reduce the riveting work of two blocks of side plates and base plate, can directly the copper bar that bandages be placed in the mounting groove, installs very conveniently.Base plate 1 cooperates the formation mounting groove with side plate 2, described cover plate 3 cooperates formation hermetic cavity body with mounting groove, mounting groove and cover plate 3 riveted joints; Further, be distributed with heat-dissipating fin 4, can be used to improve radiating efficiency like this, guarantee the operate as normal of circuit at the outer surface of base plate 1 and cover plate 3.
