Background technology
At present, the specification requirement of pulse transformer is mainly reflected in: higher electrical isolation intensity is arranged; Steeper pulse front edge is arranged; (equivalence) pulse duration of broad is arranged and less pulse transformer volume is arranged.High-frequency pulse transformer is considered to realize the ideal scheme of these specification requirements.In the prior art, high-frequency pulse transformer is difficult to take into account simultaneously the characteristic of high frequency and high withstand voltage two aspects, or lays particular emphasis on high frequency, or lays particular emphasis on high withstand voltage.Can take into account high frequency and high withstand voltage high-frequency pulse transformer simultaneously, its operating frequency and withstand voltage level are about 10KHZ and thousands of volt, and its volume and pulse front edge mainly are subjected to the restriction of operating frequency.
For guaranteeing the equipment reliability service, the convertor assembly that some is main, as large-scale, ultra-large type generator static excitation equipment, electrical isolation intensity, volume and the pulse duration of pulse transformer are had higher requirement.
The utility model content
The utility model technical issues that need to address, promptly the purpose of this utility model is in order to provide a kind of high frequency high withstand voltage pulse transformer.
Technical problem of the present utility model can solve by taking following measure:
The high withstand voltage pulse transformer of a kind of high frequency, its design feature is: be made up of closed annular magnetic core, low pressure skeleton, high pressure skeleton and shell, ring type magnetic core one side is passed the low pressure skeleton, and the high pressure skeleton is enclosed within the low pressure skeleton, and 2～4 mm clearance are arranged between the two; Shell is sealed low pressure skeleton, high pressure skeleton, and pour into epoxy resin; Primary coil on the low pressure skeleton around after be cross over elementary line outlet and draw with contact pin, secondary coil is evenly being drawn with lead from line outlet after the coiling on the high pressure skeleton.
Technical problem of the present utility model also can solve by taking following measure:
Primary coil has 20～26 circles, and secondary coil has 10～13 circles.
