Abstract
The invention discloses a radiator of an oil-immersed type transformer, which comprises connecting flanges, oil ducts and radiating fins. The connecting flanges are arranged on both ends of the oil ducts, and the oil ducts are communicated with oil passages inside the radiating fins; the radiating fins consist of a set of radiating fin units with trapezoid oil passages by mutual matching; and each radiating fin consists of two radiating fin units with the trapezoid oil passages by mutual matching. The radiator provided by the invention has large effective radiating area, high mechanical strength and can meet the requirements of ultrahigh-pressure and large-capacity transformers.
Description
Technical field
The present invention relates to a kind of oil-filled transformer, specifically a kind of radiator that is used for the energy-efficient oil-filled transformer of 110KV-220KV.
Background technology
In transformer when operation,, the heat that loss the produced dissipation in time in winding and the iron core is gone out, in order to avoid overheated and cause insulation damages.To small capacity transformer, external surface area is relatively large with the ratio of transformer volume, can adopt self cooling mode, heat can be left by radiation and free convection.Self cooling mode is applicable to indoor miniature transformer, for fire preventing, generally adopts dry type, without oil immersion.Because loss and its volume of transformer are proportional, so along with the increase of transformer capacity, its volume and loss will increase with the core dimensions cube, and external surface area is only according to the quadratic power increase of size.Therefore, high-power transformer iron core and winding should be immersed in the oil, and take the cooling provision of oil.Most distribution transformers and many power transformers all adopt this mode.The capacity smaller transformer, smooth tank surface just is enough to oil cooling but; Intermediate size transformer, tank surface will be made wrinkle shape with the increase radiating surface, or install chip or flat-tube radiator additional, and oil is circulated in radiator; The high-power transformer tank surface should add radiator.
The effect of fin type heat radiator for transformer is to reduce the temperature of transformer in running, reaches the purpose of long-term optimum work of time.Along with the increase to high pressure, superhigh pressure, high-power transformer demand, the demand of the gilled radiator of transformer special use is also increasing.
At present, oil-filled transformer is the temperature rise that utilizes its radiator to reach to reduce transformer oil, and this gilled radiator is made up of a plurality of fin, and each fin is after being pressed into the flute profile oil duct by sheet metal, two assembly weldings become a slice fin, and then assembly welding becomes gilled radiator.The cross section of existing each radiator fin is a circular arc, and not only the efficiently radiates heat area is little, and the mechanical strength of radiator is low, can not satisfy the demand of present superhigh pressure, high-power transformer.
Summary of the invention
In order to overcome the deficiencies in the prior art, the purpose of this invention is to provide a kind of radiator of oil-filled transformer.This radiator efficiently radiates heat area is big, and the mechanical strength height of radiator can satisfy the demand of superhigh pressure, high-power transformer.
The objective of the invention is to be achieved through the following technical solutions:
A kind of radiator of oil-filled transformer comprises adpting flange, oil guide pipe and fin, and adpting flange is arranged on the oil guide pipe two ends, and the oil duct in oil guide pipe and the fin communicates; It is characterized in that: described fin is made of one group of fin unit cooperation that has trapezoidal oil duct.
Among the present invention, single fin is made of two fin unit cooperations that have trapezoidal oil duct.
The present invention adopts continuous rolling forming technology to produce fin unit, and adopt the mold pressing depth control technology to make the fin unit assembling fit in radiator, the radiator that obtains has the trapezoid cross section oil duct, the efficiently radiates heat area increases, improved the heat dispersion of radiator greatly, improve the mechanical strength height of radiator simultaneously, can satisfy the demand of superhigh pressure, high-power transformer.
The present invention is applicable in the energy-efficient oil-filled transformer of 110KV-220KV.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the cross section structure schematic diagram of fin among the present invention.
Embodiment
A kind of radiator of oil-filled transformer of the present invention is seen Fig. 1, and this radiator comprises adpting flange 1, oil guide pipe 2 and fin 3, and adpting flange 1 is arranged on oil guide pipe 2 two ends, and the oil duct in oil guide pipe 2 and the fin 3 communicates.Fin 3 is made of one group of fin unit 31 cooperation that have trapezoidal oil duct.Fig. 2 is the cross section structure schematic diagram of fin 3.Single fin 3 is made of two fin unit 31 cooperations that have trapezoidal oil duct.
Adopt continuous rolling forming technology to produce fin, and adopt the mold pressing depth control technology to produce fin unit, assembling fits in radiator, the radiator that obtains has the trapezoid cross section oil duct, the efficiently radiates heat area increases, improve the heat dispersion of radiator greatly, improved the mechanical strength height of radiator simultaneously, can satisfy the demand of superhigh pressure, high-power transformer.
For lifting by crane conveniently.On oil guide pipe 2, be provided with hanger 4.During use, radiator is installed on the sidewall of oil tank of transformer after by adpting flange 1 oil guide pipe 2 being communicated with, and makes oil tank of transformer and this radiator form one, can realize reducing the temperature rise that transformer produces when work.
