The utility model provides a be favorable to reducing the temperature rise of high frequency reducing transformer, effectively reduce the electrically conductive sectional area of high frequency reducing transformer level low voltage coil winding simultaneously, practice thrift the former material consumption of secondary low voltage coil winding, secondary low voltage coil winding preparation in addition, the simple and easy high frequency strong current transformer of assembly.
Description
Technical field
This utility model relates to a kind of transformator, is specifically related to a kind of water-cooled step-down transformer being applicable to high-frequency work environment.
Background technology
The high frequency voltage descending transformer secondary output low-voltage coil winding of prior art is to be formed by enamel-covered wire or insulated conductor coiling, but when transformator needs to export low-voltage, big electric current, the conductive cross-sectional area being accomplished by transformer secondary output low-voltage coil winding increases accordingly, just can make the temperature rise of transformer secondary output low-voltage coil winding within design span of control, like this also result in transformer secondary output low-voltage coil winding volume to increase, thus taking the greater room of magnetic core of transformer so that the coiling of transformer secondary output low-voltage coil winding becomes extremely difficult.How to reduce conduction cross-sectional area and the temperature rise of high frequency voltage descending transformer secondary output low-voltage coil winding, be industry problem demanding prompt solution.
Summary of the invention
It is desirable to provide one advantageously reduces high frequency voltage descending transformator temperature rise, the most effectively reduce the conductive cross-sectional area of high frequency voltage descending transformer secondary output low-voltage coil winding, save the high frequency heavy-current transformer of secondary low-voltage coil windings raw materials consumption.
Technical scheme is as follows:
A kind of water-cooled transformer, including primary high pressure coil windings, secondary low-voltage coil windings and soft magnetic materials magnetic core, it is characterized in that, described secondary low-voltage coil windings includes that coiling two circles can be provided with insulating trip by the hollow metal tube of current between hollow metal tube circle and circle.Hollow metal tube mainly includes copper and aluminum matter two kinds.
Above-mentioned primary high pressure coil windings is around in the upper and lower both sides of secondary low-voltage coil windings.Primary high pressure coil windings and secondary low-voltage coil windings both windings are on the axle center within soft magnetic materials magnetic core.
Above-mentioned soft magnetic materials magnetic core has n group, and n is the integer of 1～20.Soft magnetic materials magnetic core is traditionally arranged to be 2,4,6,8,10,12,14,16,18,20 groups.
The extraction position, hollow metal tube initial and end two ends of above-mentioned secondary low-voltage coil windings is provided with end pole metallic plate；The metallic plate being welded with as end pole is taken out in the middle part of the hollow metal tube of secondary low-voltage coil windings.Middle part is taken out and is welded the metallic plate as end pole and facilitate the high-current leading of secondary low-voltage coil windings and go out.
Beneficial effects of the present invention: one be the secondary low-voltage coil windings to transformator use hollow metal tube and in hollow metal tube water flowing cooling radiating mode, thus effectively reduce transformator run time temperature, extend transformator service life；Two is owing to secondary low-voltage coil windings is a metal tube around two circles, makes, assembles simply, thus has saved production cost；Three is that primary high pressure coil windings is around in the upper and lower both sides of secondary low-voltage coil windings, advantageously reduces the overall dimensions of soft magnetic materials magnetic core, saves soft magnetic materials magnetic core raw material and reduces cost in view of primary high pressure coil windings takes up room relatively big.

Detailed description of the invention
For being illustrated more clearly that present disclosure, it is further described with detailed description of the invention below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, a kind of water-cooled transformer i.e. high frequency big current buck transformator, including primary high pressure coil windings 2, secondary low-voltage coil windings 1 and soft magnetic materials magnetic core 3, described secondary low-voltage coil windings 1 includes coiling two circles can be by the hollow metal tube 11 of current, it is provided with insulating trip 4 between hollow metal tube 11 circle and circle, plays isolated insulation effect.Primary high pressure coil windings 2 uses heatproof insulated conductor, hollow metal tube 11 mainly to include copper and aluminum matter two kinds.
Primary high pressure coil windings 2 is around in the upper and lower both sides of secondary low-voltage coil windings 1.Primary high pressure coil windings and secondary low-voltage coil windings 1 both windings are on the axle center within soft magnetic materials magnetic core 3.Soft magnetic materials magnetic core 3 has 8 groups, is arranged on insulating base 8 internal.
As in figure 2 it is shown, the extraction position, hollow metal tube 11 initial and end two ends of secondary low-voltage coil windings 1 is provided with end pole metallic plate 5 and 6；The metallic plate 7 being welded with as end pole is taken out in the middle part of the hollow metal tube 11 of secondary low-voltage coil windings 1.Middle part is taken out and is welded the metallic plate 7 as end pole and facilitate the high-current leading of secondary low-voltage coil windings 1 and go out.
Time actually used, in hollow metal tube 11 internal water flowing 12 cooling heat radiation, by constantly circulation, thus effectively reduce temperature when transformator runs, extend the service life of transformator.
Above-described embodiment is not construed as limiting the scope of the invention, and those skilled in the art, based on being altered or modified that technical scheme or means are made, all should fall within the scope of the hereto appended claims.
