Abstract
The utility model provides a hollow copper bus conductor and a bus conduct device assembled with the conductor; the cross section of the conductor is rectangle; the cross section of the hollow part of the conductor is also rectangle; the area of the cross section of the hollow part accounts for 70 percent-90 percent of the whole area of the cross section of the conductor; the conductor is provided with a coating; and the tail end and insertion port of the conductor are not provided with coatings; and the bus duct comprises the hollow copper bus conductor, a shell and a support piece.
Description
Technical field
The utility model belongs to the bus duct device field, the especially a kind of electric conductivity that can save limited resources and remain valid of green, high reliability and the cheap relatively bus duct device of cost.
Background technology
Traditional bus-bars conductor, the large size conductor of copper metal material normally, its shortcoming is that the sectional area owing to bigger causes the large usage quantity of copper, thereby causes cost also higher, and the bus duct that is equipped with this bus-bars conductor also has corresponding higher cost.
Goal of the invention
Provide a kind of saving material and structural strength satisfactory new copper bus-bars conductor, it can reach desired current delivery purpose and matching requirements.The bus duct that is equipped with this copper busbar conductor also correspondingly can reach the purpose of current delivery.
The utility model content
According to the principle of electric current kelvin effect, conductor is in the transmission current process, and its inner core part is without current-carrying, and electric current mainly is distributed on the conductor near surperficial position, so the conductor of central shaft and close central shaft part is to not contribution of current delivery.The utility model provides a kind of copper busbar conductor of hollow structure, the cross-sectional area of its hollow space accounts for 10%～90% of the total cross-sectional area of conductor, in a specific embodiment, described copper busbar conductor is that the cross section with rectangular cross section and hollow space also is a rectangle, the area of section of this hollow space accounts for 50%～90% of the total cross-sectional area of conductor, is preferably 70%～90%.According to the utility model, conductive surface is coated with coating, and this coating is conventional insulating coating or conventional heat radiation coating, to satisfy the requirement of insulation or heat radiation electric property.This structure can effectively be saved limited resources and be kept high reliability again, has reduced cost significantly.
The bus duct device that is equipped with this bus-bars conductor correspondingly also has the advantage that economizes on resources with high reliability, and can significantly reduce cost.
Below in conjunction with accompanying drawing and example the utility model is described further.
Description of drawings
Fig. 1 is the utility model bus duct structural section figure;
Fig. 2 is a copper busbar conductor end view among Fig. 1.
Embodiment
Fig. 1 is for adopting the bus duct structural section figure of hollow copper bus-bars conductor, and this bus duct comprises closure 1, hollow bus-bars conductor 2, strutting piece 3.Shell 1 bears external force, protects the conductor in it; Hollow bus-bars conductor 2 is A phase, B phase, C phase, N phase, and ground wire etc., carrying and tapping current or protection equipment personal safety, strutting piece 3 provides at interval for each conductor and supports, and strutting piece 3 insulate.
Fig. 2 is the part end view (wherein having omitted the segment conductor on the length direction) of Fig. 1 median generatrix conductor, and it comprises: do not have the terminal part 2-1 of coating, do not have the interface 2-2 of coating, and the painting part 2-3 of seal coat.Wherein, terminal part 2-1 is connected with the joint contact of each section of bus duct; Interface 2-2 is connected with the slotting pawl contact of jack box; Painting part 2-3, transmission of electricity carrier as disconnected position, wherein, the area of terminal part 2-1 part and interface 2-2 part is determined by the contact area of the union piece that contacts, and the conductor at the conductor at conductor ends portion 2-1 position and/or interface 2-2 position is a solid construction.
Claims (5)
