Abstract
The utility model relates to a universal type coil fastening disc which comprises an upper pressing plate and a lower pressing plate. The upper pressing plate is provided with an upper pull rod hole and an upper lead hole, the lower pressing plate is provided with a lower pull rod hole and a lower lead hole, and a fastening pull rod penetrates through the upper pull rod hole and the lower pull rod hole. The universal type coil fastening disc can be used for coils of transformers of various types with the capacity under 63000 kVA, is suitable for coils of all sizes, and is universal; a large amount of iron rings are saved, and the problems that transformer coils are uneven in stress and prone to deformation when being clamped are solved. Technical defects of the coil manufacturing process are overcome, and technical level is improved; labor intensity is lowered, and work efficiency is improved.
Description
Technical field
The utility model relates to a kind of electric power system coil fastening device, relates in particular to a kind of universal coil fastening disk, belongs 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.
Utility model content
The utility model, for above-mentioned problems of the prior art, through conscientiously researching and analysing test, provides 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.
The technical solution of the utility model 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.
The utility model has the advantages of 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 utility model.
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 the utility model structure to produce 9 pairs.
The utility model is to producing 1 SZ11-20000/66 power transformer and 2 SZ11-5000/66 power transformers are tested, adopt the utility model structure, 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.
