Abstract
The utility model relates to a flatwise winding high frequency high voltage transformer, comprising a core which has a flatwise winding high voltage winding (5) provided with a low-voltage input terminal(4) and a high-voltage output terminal(3), which is characterized in that the flatwise winding high voltage winding (5) is sealed into the vacuum casting solid resin body from which extracts the low-voltage input terminal(4) and the high-voltage output terminal(3) of the wingding in which the interlayer is provided with a insulating wave-shaped plate(6). Replacing the oil-paper insulation with solid resin insulation is good for miniaturization of the structure and increases the qualification rate of the product while replacing the capacitor paper with the wave-shaped plate increases the thickness of the insulating layer between the winding inerlayers and greatly reduces the interlayer capacitor of high-voltage transformer.
Description
Technical field
The utility model belongs to a kind of transformer, especially for the high frequency high voltage transformer in high frequency X-line generator power, gas laser power supply, electrostatic precipitation and the electrostatic spraying high voltage source.
Background technology
At home and abroad in the X-line generator, its high-tension transformer winding adopts the oil-paper medium as High-Voltage Insulation usually at present, winding adopt layering flat around.The high pressure winding, has the following disadvantages as High-Voltage Insulation with the oil-paper medium:
1, its dielectric strength is relatively poor, is unfavorable for the structure miniaturization of high frequency high voltage transformer.
2, its insulation processing must be taked vacuum oil technology, and is higher to manufacturing and maintenance of equipment specification requirement.Because the defective of oiling technological operation causes domestic manufacturer's product high tension dielectric strength test qualification rate on the low side.
3, its interlayer liner kraft capacitor paper, because of its thinner thickness causes layer capacitance bigger, capacitance current is very big when operating frequency improves, and has reduced efficient.
Summary of the invention
For overcoming the defective of prior art, the technical problems to be solved in the utility model provides a kind of compact conformation, low the putting down around high frequency high voltage transformer of layer capacitance.
For achieving the above object, the technical solution adopted in the utility model is: a kind of flat around high frequency high voltage transformer, it comprises iron core, be with flat on the iron core around the high pressure winding, winding is provided with low pressure input terminal and high-voltage output end, it is characterized in that: described putting down in the high pressure winding is encapsulated in vacuum pouring hard resin body admittedly, the low pressure input terminal of described winding and high-voltage output end are drawn in vacuum pouring hard resin body, and the interlayer of winding is provided with the insulation corrugated plating.
The beneficial effect that the utility model reaches compared to existing technology is: the utility model replaces oil-impregnated paper insulation with the hard resin insulation, because the dielectric strength of resin material is much higher than transformer oil, helps the structure miniaturization and improves product percent of pass.Replace kraft capacitor paper with corrugated plating, make thickness of insulating layer increase between winding layers, can reduce the high-tension transformer layer capacitance significantly.

Embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
As shown in Figure 1, this example is provided with high-frequency core 2, be with flat on the iron core 2 around high pressure winding 5, winding 5 is provided with low pressure input terminal 4 and high-voltage output end 3, winding 5 is encapsulated in the vacuum pouring hard resin body 7 admittedly, the hard resin body is the epoxy resin body, because the dielectric strength of resin material is much higher than transformer oil, helps the structure miniaturization and improves product percent of pass.The undulatory insulation corrugated plating 6 that the interlayer of flat red high pressure winding 5 uses fiber material to make owing to strengthened the thickness of insulating barrier, can reduce the layer capacitance of high frequency high voltage transformer winding significantly.
The utility model can be a series connection voltage multiplying rectifier high frequency high voltage transformer, also can be the bridge voltage-double rectification high frequency high voltage transformer, can be applied to the high frequency high voltage transformer in high frequency X-line generator power, gas laser power supply, electrostatic precipitation and the electrostatic spraying high voltage source.
