Abstract
The utility model relates to a pie winding with an oil guide paper tube. The pie winding comprises multiple wire pies, a coil paper barrel, oil guide paper tubes and a coil folding screen, wherein the wire pies are piled together; the coil paper barrel is arranged at one side of the wire pies; the coil folding screen is arranged at the other side of the wire pies; a branch oil duct is formed between two adjacent wire pies; main oil ducts are respectively formed between the wire pies and the coil paper barrel and between the wire pies and the coil folding screen; the main oil ducts are communicated with the branch oil duct; the oil guide paper tubes are arranged in the main oil ducts at equal distance. According to the pie winding, the oil guide paper tubes are arranged in the oil ducts, and transformer oil can circuitously flow, so that the pie winding is full in heat dissipation, the size of the transformer is reduced, materials are saved, and the cost of the transformer is reduced.
Description
Technical field
The utility model relates to a kind of building block of transformer, is specifically related to a kind of disc coil with Oil Guide paper tube, and distribution transformer and power transformer that it is applicable to medium-sized or above 10kV, 35kV, 110kV level, belong to potential device technical field.
Background technology
Traditional distribution transformer and the continous way of power transformer or helical winding head end oil duct be 6mm and the alternately placement of 8mm oil duct normally, the oil duct of normal reach is not less than 5mm conventionally, transformer oil circulation is to flow from lower to upper, cold oil flows from the bottom up, take away the heat of coil surface, entering that transformer oil in line cake flows is very slowly, also be irregular, therefore, coil oil duct must be obtained enough large, the temperature rise value of guarantee coil is in the scope of standard, so, the volume of whole coil is just very large, thereby to the volume of whole transformer is increased, transformer consumptive material is too many.
Therefore, for solving the problems of the technologies described above, necessaryly provide a kind of structure improved disc coil with Oil Guide paper tube that has, to overcome described defect of the prior art.
Utility model content
For addressing the above problem, the purpose of this utility model is to provide a kind of good heat dissipation effect, the disc coil with Oil Guide paper tube that volume is little and cost is low.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of disc coil with Oil Guide paper tube, and it comprises some line cakes, coil paper tube, Oil Guide paper tube and coil screen; Wherein, described some line cakes are stacking setting; Described coil paper tube is arranged at a side of line cake, and described coil screen is arranged at the opposite side of line cake; Between described adjacent two line cakes, be formed with an oil duct; Between described line cake and coil paper tube, be formed with respectively main oil gallery between line cake and coil screen, this main oil gallery and an oil duct are interconnected; Equally spaced being arranged in main oil gallery of described Oil Guide paper tube.
The disc coil with Oil Guide paper tube of the present utility model is further set to: described Oil Guide paper tube is hollow structure and has elasticity, and its thickness is 3mm, and external diameter is 11mm.
The disc coil with Oil Guide paper tube of the present utility model is also set to: the width of described oil duct is 2 ~ 4.5mm.
Compared with prior art, the utlity model has following beneficial effect: disc coil of the present utility model by arranging Oil Guide paper tube in oil duct, and transformer oil can roundaboutly flow, thereby make coil heat radiation fully, reduce the volume of transformer, save material, reduce the cost of transformer.
Accompanying drawing explanation
Fig. 1 sectional drawing with the disc coil of Oil Guide paper tube of the present utility model.
Embodiment
Refer to shown in Figure of description 1, the utility model is a kind of disc coil with Oil Guide paper tube, and it is comprised of several parts such as some line cakes 1, coil paper tube 2, Oil Guide paper tube 3 and coil screens 4.
Wherein, described some line cakes 1 are stacking setting, are formed with an oil duct 5 between described adjacent two line cakes 1.The width of this oil duct 5 is 2 ~ 4.5mm.
Described coil paper tube 2 is arranged at a side of line cake 1, and described coil screen 4 is arranged at the opposite side of line cake 1.
Between described line cake 1 and coil paper tube 2, be formed with respectively main oil gallery 6 between line cake 1 and coil screen 4, this main oil gallery 6 and an oil duct 5 are interconnected.
The greatest improvement part of disc coil of the present utility model is: described Oil Guide paper tube 3 is equally spaced to be arranged in main oil gallery 6.Described Oil Guide paper tube 3 is for hollow structure and have elasticity, and its thickness is 3mm, and external diameter is 11mm.This Oil Guide paper tube 3 is to be bonded between line cake 1 and coil paper tube 2, coil screen 4 by white glue with vinyl.
The design principle of the disc coil with Oil Guide paper tube of the present utility model is as follows: the oily flow path direction in coil from bottom to top, when running into Oil Guide paper tube 3, stopped, force oily flow line cake 1 interior mobile, like formation labyrinth, oil stream is roundabout upwards, transformer oil directed flow, so, the transformer oil that heat in coil just can be flowed is fully taken away, thereby reduced the temperature rise in coil, therefore, can greatly reduce the volume of coil and the volume of whole transformer, also can save silicon steel sheet, copper cash, cardboard, insulating part, steel etc., the cost that has reduced transformer is high, also can meet the performance parameter requirement of transformer simultaneously.The disc coil with Oil Guide paper tube of the present utility model is applicable to all transformers of structure of low pressure, middle pressure and the high-tension coil of the distribution transformer of medium-sized or above 10kV, 35kV, 110kV level and power transformer continous way, the disc coil such as spiral.
Above embodiment is only the preferred embodiment of this creation, not in order to limit this creation, any modification of making, is equal to replacement, improvement etc., within all should being included in the protection range of this creation within all spirit in this creation and principle.
