Abstract
The invention relates to a universal coil fastening disc, which comprises an upper pressure plate and a lower pressure plate, wherein upper pull rod holes, an upper lead hole, lower pull rod holes and a lower lead hole are respectively formed in the upper and lower pressure plates, and a fastening pull rod penetrates through the upper and lower pull rod holes. The universal coil fastening disc provided by the invention can be used by various models of transformer coils with the capacity of less than 63000kVA, and is suitable for all sizes of coils to realize universality; a lot of iron coils can be saved, and the problem that the transformer coil unevenly bears force and easily deforms when being clamped is also solved. The process defects in the manufacturing process of the coils are overcome, the technological level is improved, the labor intensity is reduced and the work efficiency is improved.
Description
Technical field
The present invention relates to a kind of electric power system coil fastening device, relate in particular to a kind of universal coil fastening disk, belong to electric power application.
Background technology
Coil is the heart component of transformer, and its manufacture work is very important.The transformer coil that coiling completes must be fixedly clamped as early as possible, the clamping element of existing use is that internal diameter is identical with coil, iron ring with eight screw rod tensions, due to the internal-and external diameter of iron ring is poor can not be excessive, iron ring is when coil carries out compression section construction, the distortion that is all distorted, also there is metaboly in coil thereupon, the use of iron ring is very unreliable.In addition, because the capacity model of transformer is different, coil specification is widely different, need to make the different iron ring of large quantities of diameters, 9 pairs of a kind of needs of capacity model, 5000kVA to 63000kVA just need at least make 108 pairs, need to expend a large amount of steel, and large quantities of iron rings is put the place that takies bulk, selects and wastes time and energy, very inconvenient.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, through conscientiously researching and analysing test, provide a kind of universal coil fastening disk, stressed irregular while having solved the clamping of prior art coil, the problem easily deforming; And reduced cost.
Technical scheme of the present invention is as follows:
Comprise top board and lower platen, be respectively arranged with upper connecting rod hole, upper fairlead and lower link hole, lower fairlead on top board and lower platen, fastening pull rod is through upper and lower tie rod hole.
The one side that described top board contacts with coil is smooth flat, and another side arranges reinforcement.
The one side that described lower platen contacts with coil is smooth flat, and another side arranges reinforcement.
Described reinforcement is crisscross arranged.
Described top board and lower platen are the quadrangle with rounded corner.
Described upper and lower tie rod hole is 4.
Four described upper and lower tie rod holes are all diagonal angle setting.
Described upper connecting rod hole and lower link hole match, and upper fairlead and lower fairlead match.
Advantageous effect of the present invention is as follows:
1, because of what adopt, be plate armature, can meet capacity each model transformer coil below 63000kVA and use, the coil of applicable all size dimensions, has realized general; Can save a large amount of iron rings, discontinuity while simultaneously also having solved transformer coil clamping, yielding problem.Eliminate the defective workmanship in coil manufacture process, improved technological level; Reduce labour intensity, improved operating efficiency.
2, upper lower platen adopts square band rounded corner, and convenient layout strengthened gusset.
3, the reinforcement that is crisscross arranged, not only reinforces upper lower platen, has alleviated again the weight of upper lower platen in the situation of proof strength.Simultaneously for arranging lead-in wire perforate slot milling.
4, four tie rod holes are diagonal angle setting, fastening pull rod through time not only easy to operate, and transformer coil while clamping stressed evenly, not yielding.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure, 1, top board, 2, lower platen, 3, upper connecting rod hole, 4, lower link hole, 5, upper fairlead, 6, lower fairlead, 7, reinforcement.
Embodiment
Embodiment
As shown in Figure 1, comprise top board 1 and lower platen 2, top board and lower platen are the quadrangle with rounded corner; The one side that described top board contacts with coil is smooth flat, the another side reinforcement 7 that is crisscross arranged; The one side that lower platen contacts with coil is smooth flat, the another side reinforcement that is crisscross arranged.
On top board and lower platen, be respectively arranged with upper connecting rod hole 3, upper fairlead 5 and lower link hole 4, lower fairlead 6, upper connecting rod hole and lower link hole match, and upper fairlead and lower fairlead match.Described tie rod hole is 4, and four tie rod holes are diagonal angle setting.Fastening pull rod is through upper and lower tie rod hole.
Above lower platens, 4 fastening pull rods can carry out fastening to different size coil to adopt structure of the present invention to produce 9 pairs.
The present invention is to producing 1 SZ11-20000/66 power transformer and 2 SZ11-5000/66 power transformers are tested, adopt structure of the present invention, a set of equipment is realized the fastening of different capabilities coil, eliminated the yielding shortcoming of the fastening transformer coil of the different iron rings of original use, improve the quality of transformer coil, saved the steel of making iron ring simultaneously, saved 180 kilograms for every, save 540 kilograms, be worth 8100 yuan for 3.
