Depressor, oil sealing high-tension transformer are a kind of structural shapes of transformer, i.e. the coil of transformer impregnates in the oil.Oil sealing is high
Pressure transformer is typically mounted in individual structure for fixing transformer part, oil sealing high-tension transformer has since fireproof needs
Volume is big, of high cost, requirements of installation space is high so it is very not square that oil sealing high-tension transformer is used when product design
Just.Meanwhile as double-dielectric barrier discharge low-temperature plasma apparatus for, the prior art needs to set independent resonance electricity
Sense, thus further improves space requirement during product design so that and the volume of the final shaping product further increases, into
This is also improved therewith.
Utility model content
The purpose of this utility model is to provide a kind of high frequency high voltage transformer, and the utility model uses dry-type transformer generation
It replaces, it is small, it is at low cost, it occupies little space, while by the use of the leakage inductance of dry-type transformer as resonant inductance, instead of independent
Resonant inductance.
The above-mentioned technical purpose of the utility model technical scheme is that：Including low pressure winding, height
Press winding, magnetic core, stationary fixture；The low pressure winding and the high-voltage winding are respectively distributed to two of the magnetic core solely
Vertical and the high-voltage winding is by being divided to two independences that slot skeleton is fixed on the same magnetic core on arm on arm, described
Winding housing is provided on the outside of high-voltage winding, one end of the winding housing is provided with extraction penetration pipe.
As the preferred of the utility model, carried out in the winding housing by filling epoxy resin or heat conductive silica gel
Embedding.
As the preferred of the utility model, the low pressure winding is less than the coiling line coiling of 1mm using litz wire or line footpath
It forms.
As the preferred of the utility model, the magnetic core is U-shaped magnetic core, magnetic core tool there are two the independence around
Arm.
As the preferred of the utility model, described dividing on slot skeleton is provided with multiple rows of winding slot parallel to each other, described
Threading notch is provided on the cell wall of winding slot.
As the preferred of the utility model, the low voltage winding parallel is set in high-voltage winding.

Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
As shown in Figure 1 and Figure 2, the utility model embodiment include low pressure winding 1, high-voltage winding 2, magnetic core 3, for fixing
The stationary fixture 4 of low pressure winding 1 and high-voltage winding 2, wherein stationary fixture 4 use metal fixture, and magnetic core 3 is fixed on stationary fixture
On 4, magnetic core 3 is U-shaped magnetic core 3, and the tool of magnetic core 3 is there are two parallel to each other independently around arm.Low pressure winding 1 is parallel to high-voltage winding 2
It sets.
Low pressure winding 1 and high-voltage winding 2 are respectively distributed to two independences of magnetic core 3 on arm, and high-voltage winding 2 passes through
It is divided to two independences that slot skeleton 6 is fixed on same magnetic core 3 on arm, which can cause bigger leakage inductance, and this
Leakage inductance just may be used as resonant inductance, and without designing an individual resonant inductance, the very big integrated level improved reduces
Volume, reduces cost.Low pressure winding 1 is formed using the coiling line coiling of litz wire or line footpath less than 1mm, the set-up mode
The loss brought for reducing skin effect.
The outside of high-voltage winding 2 is provided with winding housing 5, and one end of winding housing 5 is provided with for through high-voltage winding 2
Lead-out wire extraction penetration pipe 5-1, draw penetration pipe 5-1 be arranged at winding housing 5 close to the high-pressure side one side of high-voltage winding 2
End.It is an elongated output pipe to draw penetration pipe 5-1, which can effectively increase creepage distance, really
The high-pressure side of high-voltage winding 2 is protected, will not be discharged magnetic core 3, stationary fixture 4, winding housing 5.Pass through ring type filling in winding housing 5
Oxygen resin or heat conductive silica gel are potted.
As shown in figure 3, dividing on slot skeleton 6 for the utility model embodiment is provided with multiple rows of winding slot 6-1 parallel to each other,
