Abstract
The utility model discloses a low-voltage lead lug. The lead lug comprises a curved hook and a bus piece which are integrally formed; a small radian bending is formed at the connection position; and a linear type wiring head is arranged at one end of the curved hook. According to the utility model, two lugs and a vertical copper bus in the prior art are combined to one lug so as to reduce the processing for the vertical bus; and the welding points are reduced and the processing procedures of the vertical bus are simplified on condition of not changing current density and mechanical strength; and meanwhile, the problem that the resistance is increased due to the welding point increasing is solved, and the purposes of simplifying procedures and saving processing time are achieved.
Description
Technical field
The utility model relates to a kind of lead-in wire lug plate, especially relates to a kind of low-voltage lead lug plate, belongs to the design of transformer field.
Background technology
For the 10kV distribution transformer, during capacity less (usually capacity 250kVA and following), low-voltage lead can use the former line of coil directly to connect and lead-in bushing through welding, but concerning capacity 315kVA and above transformer, low-voltage lead needs connect with copper bar.Its structure is the copper busbar of one section level of the low-voltage coil place of lifting one's head welding, and one section vertical copper busbar of welding is drawn up on the copper busbar of level then, is connected with sleeve pipe through lug plate again.Like this low-voltage coil lift one's head and sleeve pipe between part have three pads at least, in sum, need now a kind of new lead-in wire lug plate of design solve the problems referred to above.
The utility model content
Deficiency to the prior art existence; The utility model technical problem to be solved is, a kind of low-voltage lead lug plate is provided, and reduced the processing of vertical copper busbar; Under the prerequisite that does not change electric close and mechanical strength, reduce solder joint, and reduced the manufacturing procedure of vertical copper busbar.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is, a kind of low-voltage lead lug plate comprises crotch and bus sheet, and its crotch and bus sheet are integral structure, and connecting portion is provided with a little radian bending; One end of said crotch is provided with a linear pattern connector lug.
Optimize, above-mentioned low-voltage lead lug plate, its lug plate adopt the thick copper strips of 0.3mm to process, and lug plate is folded and formed by copper strips.
The utility model will be originally that two-part lug plate and vertical copper busbar are merged into a lug plate; Reduced the processing of vertical copper busbar; Under the prerequisite that does not change electric close and mechanical strength, reduce solder joint; And reduced the manufacturing procedure of vertical copper busbar, and reach and both eliminated because of increasing the problem that resistance that pad brings increases, reduce operation again and practiced thrift purpose process time.
Description of drawings
Below in conjunction with accompanying drawing and embodiment to the utility model further explain;
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the prior art constructions sketch map.
Embodiment
As shown in Figure 1, the utility model is a kind of low-voltage lead lug plate, comprises crotch 1 and bus sheet 2, and its crotch 1 is an integral structure with bus sheet 2, and connecting portion is provided with a little radian bending 3, and an end of crotch 1 is provided with a linear pattern connector lug 4.Lug plate adopts the thick copper strips of 0.3mm to process, and lug plate is folded and formed by copper strips.The lug plate of Fig. 1 for directly being folded and formed by the thick copper strips of 0.3mm because it can bend, gets final product so the shape of walking that only needs to go between is roughly processed, and tiny bending can be joined curved in the scene when practical operation.The size that position of being walked according to going between and shapometer are calculated copper busbar adds that the semicircular installation of lug plate top reservation is spent in advance, converses the length of two-fold with copper strips, is processed into shape shown in Figure 1 and gets final product.Fig. 2 is former vertical copper busbar 5 and lug plate 6 two-part structures; The lug plate 6 of its middle and upper part is to be folded and formed by the thick copper strips of 0.3mm; The copper busbar 5 of bottom is to be cut to cut by the moulding copper bar to form, because copper bar is harder, therefore needs all places that need bend are all processed in advance.The bending of Fig. 2 middle and lower part can not processed in the lug plate of new construction, can on-the-spotly regulate according to actual conditions to manufacture.
The utility model is merged into one by the thick big lug plate that copper strips is folded and the back bends of 0.3mm with vertical copper busbar and lug plate; Under the prerequisite that does not change electric close and mechanical strength, reduce solder joint; And reduced the manufacturing procedure of vertical copper busbar; Reach the problem of both having eliminated the resistance increase that brings because of the increase pad, reduced operation again and practiced thrift purpose process time.The main points of the technical scheme that the utility model adopted: calculate good level and vertical size from the sleeve pipe bottom to finish lead; And the bending that takes into full account the lug plate place is spent in advance; Bend out the shape of whole lug plate according to the total length that draws; Because what use is the thick copper strips of 0.3mm, so the needs can install according to the scene time are adjusted concrete shape.
Certainly, above-mentioned explanation is not to be the restriction to the utility model, and the utility model also is not limited to above-mentioned giving an example; Those skilled in the art; In the essential scope of the utility model, the variation of making, remodeling, interpolation or replacement all should belong to the protection range of the utility model.
