Abstract
The utility model discloses an 110KV transformer high voltage coil structure which comprises a supporting bar. The coil is winded on one end of the supporting bar. The coil comprises a plurality of pancake coils layered from top to bottom. A first angle ring is arranged inside a first pancake coil which is on the top. A first cardboard is disposed between the first angle ring and the supporting bar. A second cardboard is disposed between the supporting bar and the inner side of a second pancake coil which is adjacent to the first coil cake. A second angle ring is arranged on the inner side of the bottom of the pancake coil. Soft angle rings are arranged respectively outside the first pancake coil and the bottom pancake coil. The 110KV transformer high voltage coil structure has the advantages of being high in bars fill ratio, being smaller in 'high-low' (high-middle) channel distance, and being capable of ensuring the safety and reliability of high voltage coil under the condition of impulse and power frequency voltage and the electrostatic plate is canceled owing to the cancel of electrostatic plate which is on the end portion, and lowering cost effectively. Besides, the insulation level of a winding end portion is improved owing to the special tangled structure of front ends of two pancake coils, inner pad cardboards and angle rings. Coil-out dielectric strength is enhanced by the soft angle ring.
Description
Technical field
The utility model relates to a kind of transformer part, particularly a kind of transformer high-voltage coil structure.
Background technology
The 110kV high-tension coil generally adopts " being entangled with-continous way " or " interior screen-continous way " structure now, and arranges static board in the upper end, guarantees that to promote high-tension coil is safe and reliable under impact and power-frequency voltage.But " interior screen-continous way " loop construction barred window filling rate is low, and cost is higher; The empty track pitch of tradition " being entangled with-continous way " loop construction " high-low " (or " high-in ") is from larger.And the static board of traditional 110kV high-tension coil end also increases the transformer height, namely increases transformer oil and steel plate consumption.
The utility model content
The purpose of this utility model is to provide a kind of 110kV transformer high-voltage coil structure, to solve the problems of the technologies described above.
To achieve these goals, the utility model adopts following technical scheme:
A kind of 110kV transformer high-voltage coil structure comprises support bar, and support bar one side is arranged with coil, and coil comprises a plurality of coil cakes of from top to bottom layering; The inboard of the first coil cake of top arranges the first square ring, and the first paperboard strip is set between the first square ring and the support bar, is close between the inboard of the second coil cake of the first coil cake and the support bar the second paperboard strip is set; The inboard of bottom coil cake arranges the second square ring, and the outside of the outside of the first coil cake and bottom coil cake is provided with soft corner-ring.
The utility model further improves and is: the first coil cake and the second coil cake are two wires and around single cake odd number root conductor structure of being entangled with formation.
The utility model further improves and is: the outside of the second coil cake also is provided with soft corner-ring.
Compared with prior art, the utlity model has following advantage: a kind of 110kV transformer high-voltage coil of the utility model structure, has higher barred window filling rate, the empty track pitch of less " high-low " (or " high-in ") from, and cancellation end static board, guarantee that so namely high-tension coil is safe and reliable under impact and power-frequency voltage, effectively reduce again cost; By coil head end 2 cakes special be entangled with structure and interior packing paper lath and square ring mode, promote the winding overhang insulation level, cancel simultaneously static board; Strengthen the outlet dielectric strength by soft corner-ring.
Description of drawings
Fig. 1 is the utility model coil arrangement schematic diagram;
Among the figure: 100, be entangled with the line cake, 200, square ring, 300, paperboard strip, 400, soft corner-ring, A, B, C are the three-phase head end, and X, Y, Z are that three-phase is terminal, and 1 ~ 15 numbers for wire, and A1 ~ F1 is the numbering of line cake.
Embodiment
Describe the technical solution of the utility model in detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of 110kV transformer high-voltage coil of the utility model structure comprises support bar, and support bar one side is arranged with coil, and coil comprises a plurality of coil cakes that consist of many levels, comprises successively from top to bottom the first coil cake, the second coil cake ... bottom coil cake.
The inboard of the first coil cake of head end arranges square ring 200, and paperboard strip 300 is set between square ring 200 and the support bar, is close between the inboard of the second coil cake of the first coil cake and the support bar paperboard strip also is set; The inboard of bottom coil cake arranges the outside of square ring 200, the first coil cakes, the outside of the second coil cake and the outside of bottom coil cake and is provided with soft corner-ring 400.The first coil cake and the special coiling of the second coil cake: by 2 and be entangled with around wire and form single cake odd number root conductor structure, the actual number of turn of every like this cake is the N+1/2 circle.
Although the above is described the utility model by reference to the accompanying drawings; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment only is schematic; rather than restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away from the scope situation that the utility model aim and claim protect, can also make a lot of forms, these all belong within the protection of the present utility model.
