Abstract
The utility model provides a radiating oil duct for an iron core of a large-sized transformer. The radiating oil duct for the iron core comprises an iron core sheet, wherein radiating insulating ceramic chips are distributed on the surface of the iron core sheet, and clearances among the radiating insulating ceramic chips form the radiating oil duct. After adoption of the scheme, the radiating oil duct has the greatest advantages that the thermal class of the used ceramic chips is 180 DEG C in H class and the ceramic chips are high in heat resistance and do not absorb water, so that when the ceramic chips are used to manufacture the radiating oil duct, the insulating property and the heat resistance property of the components of the oil duct of the iron core can be further improved greatly; the ceramic chips have the characteristic of not being retracted or bent, so that the structural strength of the iron core is improved, the deformation of the iron core is reduced in use, and the ability of impact and shock resistance of the iron core is improved; and furthermore, the ceramic chips adopt the round-shaped structures, so that the fluidity of oil in the iron core is further strengthened.
Description
Technical field
The utility model relates to the technical field of power equipment, refers in particular to a kind of high-power transformer iron core heat radiation oil duct.
Background technology
Convention in the industry, high-power transformer in order to solve the heat dissipation problem of iron core, increases heat radiation oil duct because its iron core diameter is bigger usually in iron core.And traditional heat radiation oil duct adopts the straight shape filler strip of cardboard as the heat radiation oil circuit; But owing to receive own high temperature insulation grade of cardboard (105 ℃ of A levels) and inotropic influence; After the transformer long-time running, heat radiation oil duct occurs aging the contraction easily and becomes flexible, and adopts straight shape filler strip as oil duct in addition; Make the oil mobility variation of transformer, totally all be unfavorable for the safe operation of transformer.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of prior art, and a kind of good heat dissipation effect, high, the difficult high-power transformer iron core heat radiation oil duct that wears out that shrinks of thermal endurance class are provided.
Be to realize above-mentioned purpose, the technical scheme that the utility model provided is: a kind of high-power transformer iron core heat radiation oil duct, include lamination, and in the surface distributed of lamination the radiating insulating potsherd is arranged, the gap between the radiating insulating potsherd constitutes heat radiation oil duct.
Described radiating insulating potsherd is circular.
Described radiating insulating potsherd is evenly distributed in the surface of lamination.
The utility model is after having adopted such scheme; Its great advantage is because the utility model has adopted potsherd to make heat radiation oil duct; Because of the thermal endurance class of the potsherd of the utility model is 180 ℃ of H levels; Thermal endurance is high, and ceramic itself the suction, and then has improved the insulation property and the heat resistance of iron core oil duct parts widely; Simultaneously,, therefore improved the structural strength of iron core, reduced the distortion in using, improved the ability of its shock resistance vibrations because potsherd also has characteristics such as do not shrink, not crooked; In addition, because potsherd adopts the toroidal structure, and then make the oil mobility grow in the iron core.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with specific embodiment the utility model is described further.
Shown in accompanying drawing 1, the described high-power transformer iron core of present embodiment heat radiation oil duct, it includes lamination 1, wherein, is evenly distributed with circular radiating insulating potsherd 2 on the surface of lamination 1, and the gap that the radiating insulating potsherd is 2 constitutes heat radiation oil duct.Below be the manufacturing process of the utility model: at first be close to lamination 1 with the cardboard of have openning hole (diameter that is slightly larger than radiating insulating potsherd 2 of hole size diameter); Dripping special-purpose glue on each hole then; Again radiating insulating potsherd 2 is put into each hole; Compress the radiating insulating potsherd of having put into 2, treat that radiating insulating potsherd 2 is bonded at back (probably lasting about 1 minute) on the lamination 1 fully, takes away cardboard; Then radiating insulating potsherd 2 is evenly distributed on the surface of lamination 1, through the gap formation heat radiation oil duct of 2 of radiating insulating potsherds.The entire making process simple and fast of the utility model; The heat radiation oil duct that adopts circular radiating insulating potsherd 2 to make simultaneously has that high directivity, insulating properties are high, area of dissipation greatly, do not shrink, be difficult for advantages such as aging; Be particularly suitable for extensively applying in the high-power transformer; Can effectively reduce the temperature rise of transformer, and the anti-short circuit capability that improves high-power transformer, be worthy to be popularized.
The examples of implementation of the above are the preferred embodiment of the utility model only, are not the practical range that limits the utility model with this, so the variation that all shapes according to the utility model, principle are done all should be encompassed in the protection range of the utility model.
Claims (3)
