Description
Technical field
The utility model relates to a kind of busbar, the busbar that particularly a kind of low-voltage distribution cabinet is used.
Background technology
Along with emerging in large numbers of modernization project facility and equipment, the power consumption of all trades and professions is fast to be increased, and can not meet the demands in the now big electric current conveying system of traditional cable as transmission pressure.In order to satisfy the big electric current delivery requirements of these systems such as transformer station, transformer and equipment; The novel distribution lead that a kind of copper, aluminum material that adopts high conductivity processed is used and is given birth to; This novel distribution lead is called busbar (bus line), be exactly in the busbar confession under directions electric system, Zong in the electric cabinet switch in system switch and each shunt circuit be connected copper bar or aluminium is arranged; The surface is done insulation and is handled, and main effect is to compile, distribute and transmit electric energy.
Rectangle or circular cross-section are adopted in busbar of the prior art cross section more, and the thickness of busbar is bigger, and be mostly into adopting the mode that is arranged in parallel in becoming power distribution cabinet.This traditional busbar structure receives the influence of kelvin effect big, and along with the increase of ampacity on the busbar, the busbar kelvin effect under the electromagnetic field effect also increases; Cause the busbar effective cross-section to descend, when electric current more than 2000 amperes the time, under electromagnetic field effect, also have proximity effect between the busbar that is arranged in parallel; Can further make the conductive effective cross section of busbar reduce again,, generally can only select more heavy in section busbar for use in order to satisfy the ampacity of busbar; But the kelvin effect of bringing thus is even more serious; Produce vicious circle at this point, cause enterprise production anxious according to increasing with copper (aluminium) amount, cost significantly rises.
The utility model content
The utility model technical problem to be solved is that a kind of kelvin effect influence busbar that low-voltage distribution cabinet little, that mechanical strength is high and thermal diffusivity is better is used is provided to above-mentioned prior art present situation.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the busbar that a kind of low-voltage distribution cabinet is used; It is characterized in that: said busbar includes the body that cross section is recessed camber line; Said body forms the along continuous straight runs setting respectively on two edges that are provided with along its length and cross section is the side portion of " one " font; Two said side portion are located along the same line; And, form the groove that runs through along the length direction of said busbar between said body and two the said side portion, be formed with breach between two described side portion at interval.
In order to increase the surface area of busbar, enlarge radiating surface, thereby reduce the temperature of busbar, as preferably, the body of said busbar is formed with on lateral wall along the length direction of this busbar to be offered and is undulatory teeth groove.Undulatory teeth groove has not only enlarged the surface area of busbar, can also increase busbar and the frictional force between the insulating part is installed, and guarantees the reliability of installing.
In order further to enlarge the surface area of busbar, preferred as further, the side portion of said busbar is formed with the raised line that is provided with along the length direction of this busbar on the top.This raised line can enlarge radiating surface on the one hand, helps the cooling of busbar, can also play spacing effect on the other hand, makes things convenient for the installation and the location of busbar.
In order to improve the performance of busbar, make things convenient for processing and manufacturing, as preferably, the body of said busbar and two side portion structure that is formed in one.
Compared with prior art; The advantage of the utility model is: the busbar that adopts polymorphic structure; This busbar is made up of body that is camber line and the side portion that is in-line; The outer circumference of this busbar can effectively enlarge the area of dissipation of busbar greater than the rectangular bus bar with the cross section, reduces the temperature of bus; And, be formed centrally groove in the busbar, help the heat radiation of busbar, enhance product performance; The thickness of the busbar material that the busbar of the polymorphic structure of the utility model is rectangular or more circular than general section is little, makes that the kelvin effect influence of busbar under the action of a magnetic field is little, helps improving the net sectional area of busbar.

Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Like Fig. 1～shown in Figure 2; The busbar of present embodiment is the busbar that cross section is polymorphic structure; This busbar includes body and side portion 12, and wherein, the cross section of body 11 is recessed camber line; Side portion 12 is shaped in body 11 respectively at the top, two edges (being the two ends of the cross section camber line of body) that is provided with along its length; And side portion 12 is that along continuous straight runs extends to the both sides, edge of body 11, and the cross section of two side portion 12 all is " one " font; Two side portion 12 are located along the same line and are provided with at interval and are formed with breach 13, form the groove 14 that runs through along the length direction of busbar 1 between body 11 and two side portion 12.
The busbar of present embodiment is different from the rectangular or circular busbar of traditional cross section; The body 11 of busbar and the thickness of side portion 12 are 4mm; Busbar thickness than traditional is little, can improve the phenomenon that kelvin effect causes the busbar net sectional area to reduce, and; The special-shaped busbar outer circumference of present embodiment has enlarged the area of dissipation of busbar effectively greater than the rectangular bus bar of equal sectional area;
In order further to enlarge area of dissipation; The body 11 of present embodiment busbar 1 also is formed with a plurality of length directions along this busbar 1 and offers and be undulatory teeth groove 111 on lateral wall; The side portion 12 of busbar 1 then is formed with the raised line 121 that is provided with at interval along the length direction of this busbar 1 on the top; Teeth groove 111 and raised line 121 can further enlarge the surface area of busbar, help the heat radiation of busbar.
As shown in Figure 3; Be the actual user mode figure of the busbar of present embodiment, this busbar is installed in the bus-bar device that low-voltage distribution cabinet uses, wherein; Bus-bar device includes top cover 3, base 4, Y shape insulating part 2 and three-phase bus bar 1; Be fixedly connected on one through bolt 5 between top cover 3, base 4 and the insulating part 2, the bottom of base 4 is connected with mount pad 6, forms three vestibules of isolating each other between the inwall of the inwall of top cover 3, base 4 and the insulating part 2 respectively; Three-phase bus bar 1 is contained in the corresponding vestibule respectively and forms a symmetric arrays structure that is " article " font; The arrangement architecture of this three-phase bus bar has solved the problem that former parallel arrangement architecture is positioned at the busbar weak heat-dissipating in centre position effectively, has guaranteed the heat radiation uniformity of three-phase bus bar, and has improved the problem that causes the busbar effective cross section to be reduced because of kelvin effect and proximity effect; Improve the radiating effect of busbar, improved the overall performance of product.
