The utility model discloses a there being under the magnetic shunt structure condition control cold oil flow path directly make it to get into the coil, can effectively reduce the transformer coil temperature rise, be applicable to all electric pressure transformers, be particularly useful for all kinds of products with larger capacity.
Description
Technical field:
The utility model relates to transformer manufacture technology, particularly a kind of forced-directed oil air-cooled transformer oil channel structures with pressing plate and magnetic shunt.
Background technology:
High-power transformer is in running, except the main flux circulated in iron core, outer also all the time along with the existence of a large amount of leakage flux at iron core.All can produce a large amount of losses in iron core, winding and steel construction piece, these losses will be transformed into conduct heat away in surrounding medium, thus cause transformer local overheating, accelerate the aging of insulating part, affect the life-span of transformer.In order to effectively control the path of leakage field circulation, folder formula magnetic shunt is used to be effective measures.The oil guide structure that forces brought subsequently is the problem needing in high-power transformer design to solve.
Utility model content:
The purpose of this utility model is to provide a kind of forced-directed oil air-cooled transformer oil channel structures with pressing plate and magnetic shunt, to solve the problems of the technologies described above.
For reaching above object, the utility model takes following technical scheme:
With a forced-directed oil air-cooled transformer oil channel structures for pressing plate and magnetic shunt, comprise oil sealing cardboard, cross-over block, magnetic shunt and coil pair pressing plate; Wherein, oil sealing paper parts is placed in the supporting bracket of iron core lower clamping piece oil guiding box, cross-over block is avoided oil guiding hole and is placed on oil sealing cardboard, cross-over block inside offers notch, this notch embeds magnetic shunt, the coil pair pressing plate with unhook groove is put on magnetic shunt top, and oil sealing cardboard remainder is used for cross-over block and coil pair pressing plate to wrap up to locate.
The utility model further improves and is, oil sealing cardboard remainder is used for cross-over block and coil pair pressing plate wrap up and are located by screw rod.
The utility model further improves and is, coil pair pressing plate offers oil guiding hole and location hole.
Relative to prior art, the utility model has following advantage:
The utility model is equipped with magnetic shunt in transformer coil bottom, such that the magnetic of iron core lower clamping piece is close becomes very little, decreases dispersion loss, can effectively prevent local overheating and ageing of insulation.Magnetic shunt top arranges the coil pair pressing plate with unhook groove and positioning screw, can extract out, the oil guiding hole complete matching of secondary coil pressing plate oil guiding hole and main coil pressing plate after making coil completely in place convenient for bracing frame.Ensure that the sealing of oil circuit is with unimpeded, effective control transformer oil importing coil inside.
Accompanying drawing illustrates:
Fig. 1 is the cross-sectional schematic of the forced-directed oil air-cooled transformer oil channel structures of the utility model band pressing plate and magnetic shunt;
Fig. 2 is the vertical view of the forced-directed oil air-cooled transformer oil channel structures of the utility model band pressing plate and magnetic shunt;
Fig. 3 is the structural representation of the utility model coil pair pressing plate.
In figure: 1 is magnetic shunt, 2 is cross-over block, and 3 is coil pair pressing plate, and 4 is oil sealing cardboard, and 100 is unhook groove, and 200 is oil guiding hole, and 300 is location hole.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 to Figure 3, a kind of forced-directed oil air-cooled transformer oil channel structures with pressing plate and magnetic shunt of the utility model, comprises oil sealing cardboard 4, cross-over block 2, magnetic shunt 1 and coil pair pressing plate 3; Wherein, oil sealing cardboard 4 part is placed in the supporting bracket of iron core lower clamping piece oil guiding box, cross-over block 2 oil guiding hole avoided on lower clamping piece is placed on oil sealing cardboard 4, cross-over block 2 inside offers notch, this notch is embedded in magnetic shunt 1, the coil pair pressing plate 3 with unhook groove 100 is put on magnetic shunt 1 top, and oil sealing cardboard 4 remainder is used for cross-over block 2 and coil pair pressing plate 3 wrap up and are located by screw rod.
Specifically, oil sealing cardboard 4 is placed in transformer lower clamping piece oil guiding box supporting bracket, and on oil sealing cardboard, in oil guiding hole position and supporting bracket, oil guiding hole is fitted.Oil sealing cardboard 4 is avoided oil guiding hole and place cross-over block 2, cross-over block 2 inside offers notch, this notch is for embedding magnetic shunt 1, coil pair pressing plate 3 is equipped with on magnetic shunt 1 top, correspondence position convinces oilhole 200 by patient analysis makes cooling transformer oil enter coil via major and minor pressing plate, and cross-over block 2 and coil pair pressing plate 3 are wrapped up and located by screw rod by last oil sealing cardboard 4.
Insulating oil flow path is as follows: insulation cold oil from lower clamping piece Oil Guide inner chamber via supporting bracket oil guiding hole, enter the inner chamber formed by oil sealing cardboard 4, cross-over block 2, magnetic shunt 1 and coil pair pressing plate 3, after entering coil pair pressing plate 3, bottom oil circuit is communicated with coil pressure plate oil guiding hole by oil guiding hole 200 by oil pocket, makes the smooth and easy inflow coil inside of insulating oil.Every two mutually of coil pair pressing plate 3, four bracing frame positions exoneration hook grooves 100 when mounting coil, make that coil is complete in placely to be extracted bracing frame out afterwards.Secondary pressing plate and pressing plate drive location hole 300 at correspondence position, can not produce skew, can accurately locate, make transformer oil stream smooth and easy during suit.Transformer oil effectively can be made so upwards to flow into coil inside cool, to reduce temperature rise, transformer safety be run.
