Embodiment
Below, describe embodiments of the invention in detail with reference to accompanying drawing.
Usually, can form busbar joint by the mode of parallel overlap joint or vertical overlap joint between the bus.
Fig. 1 to Fig. 3 shows the method for connecting bus that is used to carry out the parallel overlap joint of bus according to one embodiment of present invention.Fig. 4 shows the method for connecting bus that is used to carry out the vertical overlap joint of bus according to another embodiment of the invention.
With reference to Fig. 1 to Fig. 3 one embodiment of the present of invention are described below.
As shown in Figure 1, wanting to process at least one groove 14 and 24 respectively on the relative end surface of connected Up Highway UHW 10 and Down Highway 20, thereby a surface at Up Highway UHW 10 forms first concaveconvex structure 12, forms second concaveconvex structure 22 on Down Highway 20 and Up Highway UHW 10 facing surfaces.Wherein, the shape of first concaveconvex structure 12 and second concaveconvex structure 22 can be chimeric fully each other.Preferably, on Up Highway UHW 10 and Down Highway 20, form two grooves 14 and 24 respectively.
The concrete technology that forms groove is as follows: rule with relative being connected on the surface that Down Highway 20 will be overlapped at Up Highway UHW 10 according to design, carry out indent with mould then on each joint face.Preferably, when on Up Highway UHW 10 and Down Highway 20, forming two grooves respectively, the width b of each groove can be selected as the faying surface between Up Highway UHW 10 and the Down Highway 20 length a 1/4.At first, even compacting groove on Up Highway UHW 10, its groove depth can be preferably 1/10 in 1/20 to 1/10 scope of bus thickness; On the Down Highway 20 of butt joint, suppress groove accordingly then.The shape of groove can be straight or crooked, as long as can guarantee between Up Highway UHW and the Down Highway coupling fully.Preferably, groove forms along the Width of Up Highway UHW and Down Highway, that is, the bearing of trend of groove is perpendicular to the length direction of Up Highway UHW and Down Highway.
For the copper bound that produces in the process that forms groove, available file, emery wheel, sand paper or any other suitable modes are handled, to rub with the hands it flat or to polish.
After indent is finished, assemble in advance, fit like a glove together to guarantee Up Highway UHW 10 and contacting of Down Highway, and seamless and gap existence, thereby can't move in the horizontal and vertical directions.
If utilize bolt to connect Up Highway UHW 10 and Down Highway 20, as shown in Figure 2, correspondence position is rule on bus 10 and 20, and punching or boring then to form at least one connecting hole 16 and 26, connects to be used for bolt.If jagged or unsmooth around the connecting hole 10, then available spot-facer ream removes connecting hole orifice edge burr.Preferably, on Up Highway UHW 10 and Down Highway 20, form 4 connecting holes respectively.
After finishing the indent step and forming the step of connecting hole, the overlap joint removing surface of Up Highway UHW and Down Highway is clean, carry out surface anti-oxidation again and handle.
Particularly, carry out zinc-plated processing for copper busbar; For aluminium busbar, faying surface is warded off tin handle.
At last, after finishing above-mentioned processing, coat conductive paste immediately and assemble the overlap joint processing.
Form by the indent technology though described groove above, the invention is not restricted to this, can adopt any machining mode that can form groove, for example, dig, mill, mill, file etc.
For the situation of vertical overlap joint, except that the arranged direction difference of groove, the method for vertical connection of bus and the method for horizontally connecting of bus are basic identical.Preferably, as shown in Figure 4 and Figure 5, the bearing of trend of the groove 14a that forms on Up Highway UHW 10 is parallel to the length direction of Up Highway UHW, and the groove 24a that forms on the Down Highway 20 is parallel to the Width of Down Highway 20.Wherein, the width b of groove 14a and 24a be bus 10 width 1/4.
Though the present invention is described as embodiment in bolted mode, also can adopt the mode of any mechanical connections such as welding, riveted joint to connect Up Highway UHW and Down Highway.
Method for connecting bus according to an embodiment of the invention by forming groove respectively simply in Up Highway UHW and following Alma Mater, has increased the contact area between the bus, the busbar joint of installation, connect tight, can occurred level and the play of vertical plane.In addition, the bus that utilizes bolted mode to overlap also can be recycled, and the installation between Up Highway UHW and the Down Highway also can all reach code requirement.This method of attachment has increased contact area, has reduced contact resistance, and makes contact-making surface be difficult for oxidation, thereby has reduced the heating situation that causes owing to the contact-making surface oxidation, the fail safe of power supply-distribution system is improved, and has reduced maintenance cost.In addition, because the degree of depth of groove is not more than 10% of bus thickness, therefore, in the contact-making surface that has increased between the bus, also can guarantee drawing high and buckling strength of bus.
Though shown and described according to exemplary embodiment of the present invention, it should be recognized by those skilled in the art that without departing from the scope of the invention, can carry out variations and modifications to embodiment.
