Detailed description of the invention

Fig. 1 is utility model diagram

1. transformer case in figure, 2. first bolts, 3. transformer grounding buses, 4. multiply annealed copper wires, lug plate on 5., 6. lower lug plate, 7. the 4th bolts, 8. ground lines, 9. earth plates, 10. second bolts, 11. third bolts, 12. terminal plates.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

A kind of transformer grounding composite structure, including transformer case 1, transformer grounding bus 3, multiply annealed copper wire 4, connect Floor 9, ground line the 8, first bolt 2, the second bolt 10.First bolt 2, the second bolt 10, third bolt 11, the 4th spiral shell Bolt 7 is all T-shaped shape structure, and four bolts are all made of mold and disposably process to be formed, the first bolt 2 sequence handle from right to left Transformer grounding bus 3, upper lug plate 5 are fixed on a patch panel 12；The terminal plate 12 be located at transformer grounding bus 3 with it is upper Among lug plate 5；It is upper lug plate 5 on the left of the terminal plate 12, is transformer grounding bus 3 on the right side of terminal plate 12；On described 5 one end of lug plate is squashed structure, and the other end is the circular tube structure with plug receptacle, is equipped with the second bolt 10 on round tube, on The straightforward face of lug plate 5 is the structure of " h " word shape；The structure of the upper lug plate 5 and lower lug plate 6 designs, lower wiring Piece 6 is equipped with third bolt 11, third bolt 11 and the second bolt 10 act on；The one of 5 squashed structure of upper lug plate End is fixed on the first bolt 2, and other end circular tube structure external port is plug receptacle, convenient for patching effect with multiply annealed copper wire, the Two bolts 10 fasten multiply annealed copper wire 4；This plugging mode of upper lug plate 5 is i.e. convenient and flexible, alleviates staff's Maintenance workload improves work efficiency；4 other end of multiply annealed copper wire is equally connected with lower lug plate 6 with plugging mode It connects, and fixed with third bolt 11；The lower lug plate 6 and ground line 8, are fixed together by the 4th bolt 7, lower lug plate 6 left side is ground line 8, and right side is the 4th bolt 7；The ground line 8 is welded with earth plate 9, and the earth plate 9 falls for " Contraband " Word shape structure, disposably processes to be formed using mold, and one end is inverted fixedly embedded wall, and the other end is close to wall, makes it There is more firm contact with wall, avoids ground line 8 and the danger loosened occur because of the influence of nature and human factor, work as line When road is struck by lightning, transformer grounding can be effectively protected.

When thunderstorm weather transformer is shocked by electricity by thunder and lightning, generated heavy current passes the utility model by earth bus 3 It is delivered to lug plate 5, and sequentially passes through the multiply annealed copper wire 4 connecting with upper lug plate 5, connect down and connects with multiply annealed copper wire 4 Line piece 6, the fixed ground line 8 with lower lug plate 6,8 fixation of ground line is buried in the ground, and heavy current is connect and guides to the earth, thus It plays a protective role to transformer.

Although the utility model is described in detail with reference to the foregoing embodiments, come for those skilled in the art Say, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic into Row equivalent replacement, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should all It is included within the scope of protection of this utility model.
