Description
Technical field
The application relates to field transformer, particularly a kind of transformer fe core assembly and transformer.
Background technology
Transformer Winding is the part of comparatively core in transformer, and the quality of Transformer Winding coiling will determine the performance of a transformer.In order to make the coiling of Transformer Winding more perfect, prior art adopts direct monoblock pressing plate at the two ends of winding, so more easily winding is controlled well, but with can the flowing of clogging oil during oil duct in coil windings, reduce the heat that oily stream is taken away, have impact on transformer radiating effect.
Summary of the invention
The application provides a kind of transformer fe core assembly and transformer, and solve in prior art, coil windings can block oil duct, affects the problem of transformer heat radiation.
According to the first aspect of the application, the application provides a kind of transformer fe core assembly, comprise iron core and be wound on the coil on iron core, also comprise the top board being arranged on coil upper end, the lower platen being arranged on coil lower end and be arranged on the alternate pressing plate of coil sides, the medial surface of described top board, described lower platen and described alternate pressing plate is equipped with oil guide groove, is also provided with separator between described iron core and described coil.
Preferably, oil guide groove is from the medial surface conducting of top board, lower platen and alternate pressing plate to outer surface.
Preferably, oil guide groove distributes symmetrically on top board, lower platen and alternate pressing plate.
Preferably, separator comprises the insulation board of coated iron core and is arranged on several filler strips that insulation board medial surface or lateral surface circumferentially distribute.
Preferably, insulation board is cardboard.
Preferably, also comprise stretching screw, stretching screw is connected with lower platen with top board respectively, and for straining top board and lower platen.
According to the second aspect of the application, the application provides a kind of transformer, comprises above-mentioned transformer fe core assembly.
The beneficial effect of the application is, comprise iron core due to the application and be wound on the coil on iron core, also comprise the top board being arranged on coil upper end, the lower platen being arranged on coil lower end and be arranged on the alternate pressing plate of coil sides, and the medial surface of top board and lower platen is equipped with oil guide groove for heat radiation, also separator is provided with between iron core and coil, add the distance between iron core and coil, increase heat-dissipating space, improve the thermal diffusivity of transformer.
Accompanying drawing explanation
Fig. 1 is the cutaway view of embodiment 1;
Fig. 2 is the cutaway view of the top board of embodiment 2;
Fig. 3 is the cutaway view of embodiment 3.
Embodiment
By reference to the accompanying drawings the present invention is described in further detail below by embodiment.
Embodiment 1:
A kind of transformer fe core assembly, as shown in Figure 1, the coil 2 comprising iron core 1 and be wound on iron core 1, also comprise the top board 3 being arranged on coil 2 upper end, the lower platen 4 being arranged on coil 2 lower end and be arranged on the alternate pressing plate 5 of coil 2 sidepiece, relatively former has pressing plate and core insulation structure dimerous, top board 3, lower platen 4 and alternate pressing plate 5 form an entirety, and the rigidity of core assembly is improved by force, and make the stressed of coil evenly.And the medial surface of top board 3, lower platen 4 and alternate pressing plate 5, the side that namely top board 3, lower platen 4 and alternate pressing plate 5 contact with coil 2 is equipped with oil guide groove 30, fluid can be flowed in core assembly inner loop, thus iron core 1 is dispelled the heat.Between iron core 1 and coil 2, be also provided with separator simultaneously, just add the insulation distance between iron core 1 and coil 2, and the oil clearance between guaranteeing, ensure fluid mobility, promote its thermal diffusivity further.
Embodiment 2:
As the improvement of embodiment 1, as shown in Figure 2, be the cutaway view of top board 3, oil guide groove 30 is from the medial surface conducting of top board 3 to outer surface.Same, be also from medial surface conducting to outer surface in the oil guide groove 30 of lower platen 4 and alternate pressing plate 5.Make fluid from the outside of guidance coil 2 inside coil 2, like this, the circulating effect of fluid is better, and the thermal diffusivity brought is also better.Meanwhile, oil guide groove 30 distributes symmetrically and evenly on top board 3, make the thermal diffusivity of core assembly inside evenly.It is outstanding to that side of iron core 1 with extension 32, two extensions 32 being arranged on main part 31 two ends that top board 3 comprises a main part 31, thus form the shape of an indent, and iron core 1 can better be fixed by this shape.
Embodiment 3:
As the improvement of embodiment 1, as shown in Figure 3, iron core 1 is a kind of multi-stage stepwise iron core, separator comprises the insulation board 61 of coated iron core 1 and is arranged on several filler strips 62 that insulation board 61 lateral surface circumferentially distributes, coil 2 is coated on the outside of filler strip 62, and side clamping plate 5 are arranged on the outside of coil 2.Like this, just kept apart by insulation board 61 and filler strip 62 between iron core 1 and coil 2.Wherein, insulation board 61 can be cardboard, porcelain plate or plastic plate, and in the present embodiment, insulation board 61 is cardboard, more saves cost.
Further, core assembly also comprises stretching screw, and stretching screw is connected with lower platen 4 with top board 3 respectively, thus for straining top board 3 and lower platen 4, with fastening iron core 1.
Embodiment 4:
A kind of transformer, comprises the transformer fe core assembly of above-described embodiment.
Above content is in conjunction with concrete execution mode further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made.
