Description

A kind of L-type horizontal bus groove elbow
Technical field
The present invention relates to electric equipment field, especially a kind of L-type horizontal bus groove elbow.
Background technology
Bus duct is new circuit mode being developed by the U.S., being referred to as " Bus-Way-System ", and it is with copper Or aluminium as conductor, with non-alkene insulating supporting, be then attached to the novel conductor formed in metallic channel.Japanese really actual Using being that bus duct is developed from then in Showa 29 years (i.e. 1954).It is now electric in high room building, factory etc. Into indispensable wiring mode in equipment, power system.
In recent years, due to the needs of the various building electric power such as building, factory, and there is increased trend year by year, using original Circuit wiring pattern, i.e. poling mode, bring many difficulties during construction, moreover, when distribution system to be changed, to make its change It is simple some be nearly impossible, however, if using bus duct, very easy can achieves the goal, in addition also Building can be made to become more attractive in appearance.
In supply line, in order to realize that electric current of the busbar in horizontal or/and vertical direction is transmitted, it is necessary to pass through bus Busbar is carried out assembly connection by groove elbow in horizontal or/and vertical direction, and the connection of bus duct elbow at this stage is needed in copper bar Upper punching, this not only reduces the sectional area of copper sheet so that the temperature rise of bus duct elbow, reduces the conduction of electric conductor Performance, while short circuit accident easily occurs for the connected mode of copper bar punching, and inconvenience is connected, also it is not easy to repair and maintain, And anticorrosion effect has much room for improvement.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of L-type horizontal bus groove elbow.
In order to solve the above technical problems, the technical scheme is that:
A kind of L-type horizontal bus groove elbow, including the first busbar, the second busbar and the insulation crust for closing busbar, institute It is copper bar to state the first busbar and the second busbar, and the copper bar includes copper bar body, stainless steel substrates and thermoplastic sleeve pipe, the thermoplastic set Pipe sleeve is provided with stainless steel substrates, the copper bar sheet in copper bar body center outer surface between the copper bar body and thermoplastic sleeve pipe The outer surface that body is not cased with thermoplastic sleeve end is provided with epoxy coating, and first busbar and the second busbar structure are identical, overall In rake shape, leading portion is the flat board for being parallel to each other and leaving gap, by collecting for stage casing, is brought into close contact to each flat board of back segment It is fixed, wherein, the flat board of first busbar and the second busbar leading portion is provided with two through holes, first busbar and the second mother The back segment horizontal direction vertical welding of row is fixed.
Preferably, above-mentioned L-type horizontal bus groove elbow, the copper bar body are made up of some copper sheets overlapping.
Structure of the present invention has the advantages that:
Above-mentioned L-type horizontal bus groove elbow, its busbar are in rake shape, therefore the more existing busbar of leading portion increases, and uses process In by the through hole above it, connect outside bus duct joint, i.e., connecting copper bar is without punching, so as to lose copper bar Sectional area, and there is no the rise of temperature at busbar joint, the electric conductivity of electric conductor is improved, installation process is hardly damaged, and is made Short circuit accident is not susceptible to process, maintenance is convenient, and the special tectonic of copper bar causes antiseptic property to protrude, and is adapted to scale Industrial needs.
Brief description of the drawings
Fig. 1 is the structural representation of L-type horizontal bus groove elbow of the present invention.
Fig. 2 is the structural representation of the second busbar leading portion of L-type horizontal bus groove elbow of the present invention.
Fig. 3 is the structural representation of copper bar in L-type horizontal bus groove elbow of the present invention.

Embodiment
To further illustrate the present invention, now accompanying drawing is coordinated to be described in detail:
As Figure 1-3, a kind of L-type horizontal bus groove elbow, including the first busbar 1, the second busbar 2 and close busbar Insulation crust 4, the busbar 2 of the first busbar 1 and second is copper bar, and the copper bar includes copper bar body 1-1, stainless steel substrates (figure omits) and thermoplastic sleeve pipe 3, the thermoplastic sleeve pipe are placed on copper bar body center outer surface, in the copper bar body and thermoplastic sleeve pipe Between be provided with stainless steel substrates, the outer surface that the copper bar body is not cased with thermoplastic sleeve end is provided with epoxy coating 1-2, described Copper bar body is made up of some copper sheets overlapping, and the design makes copper sheet serve fabulous isolation while being affected by thermal expansion and contraction small Antisepsis, first busbar 1 is identical with the structure of the second busbar 2, and overall is in rake shape, between leading portion is is parallel to each other and left The flat board of gap, by collecting for stage casing, fixation is brought into close contact to each flat board of back segment, wherein, the busbar of the first busbar 1 and second The flat board of 2 leading portions is provided with two through holes 5, and the back segment horizontal direction vertical welding of the busbar 2 of the first busbar 1 and second is fixed (horizontal direction refers to that the connecting line of knuckle junction is parallel with the flat board direction of busbar leading portion).
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should It is considered as protection scope of the present invention.
