Abstract
The invention discloses a finned radiator for a transformer. The finned radiator comprises an inner oil circulating channel, wherein the inner oil circulating channel comprises linear sections and four curved transitional sections at four corners; the linear sections are connected through the curved transitional sections; and each curved transitional section is in an arc shape. By the finned radiator, the inner oil circulating channel is improved, so the circular flow resistance of transformer oil is reduced, flow speed of the transformer oil in the finned radiator is increased, and the radiating effect of the radiator is improved. The finned radiator for the transformer is particularly applied to high-efficiency and energy-saving oil-immersed transformers with the voltage of 110 to 220KV, and also applied to large power transmission and transformation equipment and direct current power transmission and transformation equipment.
Description
Technical field
The present invention relates to a kind of oil-filled transformer, specifically a kind of 110KV and above fin type heat radiator for transformer of being used for.
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, can heat be left through radiation and free convection.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 an external surface area quadratic power increase according to 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 that transformer is special-purpose is also increasing.
Oil-filled transformer is the temperature rise that utilizes its radiator to reach to reduce transformer oil; Gilled radiator is made up of a plurality of fin; Each fin is that two assembly weldings become a slice fin, and then assembly welding becomes gilled radiator after being pressed into the flute profile oil duct by sheet metal.Fig. 2 is the structural representation of fin type heat radiator for transformer in the prior art.Existing gilled radiator monolithic two is the little arc transition in right angle, transformer oil to circulate resistance big, transformer oil is little at the inner flow velocity of gilled radiator, the radiating effect of radiator is undesirable.
Summary of the invention
In order to overcome the deficiency of prior art; The purpose of this invention is to provide a kind of fin type heat radiator for transformer, this radiator has improved the inner loop oil duct, has reduced the resistance that circulates of transformer oil; Improve transformer oil at the inner flow velocity of gilled radiator, improved the radiating effect of radiator.
The objective of the invention is to realize through following technical scheme:
A kind of fin type heat radiator for transformer comprises the inner loop oil duct, it is characterized in that: said inner loop oil duct comprise straightway and with the curve transition section of four edges, straightway connects through the curve transition section, this curve transition section is a circular arc.
Among the present invention, said curve transition section is that diameter is the circular arc of 200-300 mm.
The present invention is through improving the inner loop oil duct of gilled radiator; With the little ffp filter in right angle, original monolithic two; Change is designed to the orthodrome transition, and the transformer oil that makes flows in radiator and is more prone to, and reduces the resistance that circulates of transformer oil; Improve transformer oil at the inner flow velocity of gilled radiator, improve the radiating effect of radiator.
The present invention is mainly used on 110KV and above big capacity, the EHV transformer, meets energy-efficient requirement.Reasonable in design of the present invention; Improved the area of dissipation and the mechanical strength of fin, reactor engineering result of the test that research and design detects is qualified, effective through China Atomic Energy Science Research Institute, meets standard-requireds such as JB/T5347-1999; And product uses through the user; Reaction is good, is specially adapted in the energy-efficient oil-filled transformer of 110KV-220KV, and is applied in large-scale power transmission and transformation, the direct current electric transmission and transformation.

Fig. 2 is the structural representation of fin type heat radiator for transformer in the prior art.
Embodiment
A kind of fin type heat radiator for transformer of the present invention; See Fig. 1; This gilled radiator comprises inner loop oil duct 1; Inner loop oil duct 1 comprise both sides straightway 11 and with the curve transition section 12 of four edges, straightway 11 connects through curve transition section 12, this curve transition section 12 is the circular arc of 200-300 mm.Among the figure, the 2nd, fin, the 3rd, adpting flange, adpting flange 3 is connected with inner loop oil 1.
The present invention is through improving the inner loop oil duct of gilled radiator; With the little ffp filter in right angle, original monolithic two; Change is designed to the orthodrome transition, and the transformer oil that makes flows in radiator and is more prone to, and reduces the resistance that circulates of transformer oil; Improve transformer oil at the inner flow velocity of gilled radiator, improve the radiating effect of radiator.The mechanical strength that has improved radiator simultaneously is high, can satisfy the demand of superhigh pressure, high-power transformer.
