Description

A kind of high voltage pulse transformer non-symmetric line coil structures
Technical field
The utility model is related to transformer technology field, and in particular to a kind of high voltage pulse transformer skew coil knot Structure.
Background technology
High voltage pulse transformer output voltage is very high, to ensure that built on stilts coiling is needed between insulation compressive resistance, wound core Resistance to pressure request can be met.Because transformer output voltage is high, cause transformer voltage ratio also big, i.e. the number of turn of secondary coil is also more. In conventional pulse transformer application, secondary coil is generally divided into 2 in the same size, full symmetric coil series connection, i.e., two times Level coil is equal to the isolation distance of primary coil(Δ1=Δ2), the half of coiling secondary winding turns, then the company of series connection respectively Connect.During fabrication, often by primary and secondary coil rotating around on a magnetic core post, or transformer device structure secondary coil is rotating around two On individual magnetic core post.
For primary and secondary coil rotating around the structure on a magnetic core post, need for secondary coil to make one during fabrication Coil, because secondary winding turns are more, to ensure secondary pressure-resistant to magnetic core isolation intensity and secondary turn-to-turn, the magnetic core window of transformer Size high must be made and very big on the one hand could can cause transformer too high, the size ratio of height around lower whole secondary winding turns Example is uncoordinated;On the other hand cause that magnetic core processing technology is too poor, difficulty of processing is big.
For transformer device structure secondary coil rotating around the structure on two magnetic core posts, each coiling secondary coil half The number of turn, to ensure identical insulation compressive resistance, the secondary coil insulation distance on two magnetic core posts is equal, can so cause magnetic The window width increase of core, not only increases volume, weight, the cost of magnetic core, and because the length of magnetic path of secondary coil increases Plus can cause the leakage inductance of pulse transformer to increase, and then influence pulse transformer transmitted waveform and efficiency.
Utility model content
The purpose of this utility model is to provide a kind of high voltage pulse transformer non-symmetric line coil structures, not only saves magnetic Core cost, and reduce high voltage pulse transformer leakage inductance, improve waveform transfer efficiency.
To achieve the above object, the utility model employs following technical scheme:
A kind of high voltage pulse transformer non-symmetric line coil structures, including top board, lower platen and be located at top board and push Coil rack between plate, the inside of the coil rack is provided with magnetic core, and the coil rack includes the first magnetic pole and the second magnetic Post, is wound with secondary coil respectively in first magnetic pole and the second magnetic pole, the magnetic core includes the first magnetic core post and the second magnetic Primary coil is wound with stem, the first magnetic core post and the second magnetic core post respectively, the secondary of coiling in first magnetic pole Secondary coil and second of the distance between the primary coil of coiling less than coiling in the second magnetic pole on coil and the first magnetic core post The distance between primary coil of coiling on magnetic core post.
Further, in first magnetic pole on the secondary coil and the first magnetic core post of coiling between the primary coil of coiling Distance be half in the second magnetic pole on the secondary coil of coiling and the second magnetic core post between the primary coil of coiling.
As shown from the above technical solution, high voltage pulse transformer loop construction described in the utility model, low-voltage secondary line Insulation distance between circle and low pressure preliminary coil is one of the insulation distance between high voltage second coil and primary of high voltage coil Half, the cost of magnetic core window width dimensions and magnetic core is saved, while also reducing high voltage pulse transformer leakage inductance, improve waveform Efficiency of transmission.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
The utility model is described further below in conjunction with the accompanying drawings:
As shown in figure 1, the high voltage pulse transformer non-symmetric line coil structures of the present embodiment, including top board 1, lower platen 2 And the coil rack 3 between top board 1 and lower platen 2, the inside of coil rack 3 is provided with magnetic core 4, and coil rack 3 includes Secondary coil 33,34, magnetic are averagely wound with respectively in first magnetic pole 31 and the second magnetic pole 32, the first magnetic pole 31 and the second magnetic pole 32 Core 4 includes the first magnetic core post 41 and the second magnetic core post 42, and averagely primary is wound with the first magnetic core post 41 and the second magnetic core post 42 Coil 43,44, on the magnetic core post 41 of secondary coil 33 and first of coiling in the first magnetic pole 31 between the primary coil 43 of coiling Distance less than between the primary coil 44 of coiling on the magnetic core post 42 of secondary coil 34 and second of coiling in the second magnetic pole 32 away from From.
On the magnetic core post 41 of secondary coil 33 and first of coiling in the first magnetic pole 31 between the primary coil 43 of coiling away from It is the distance between primary coil 44 of coiling on the magnetic core post 42 of secondary coil 34 and second of coiling in the second magnetic pole 32 from Δ 1 The half of Δ 2.Magnetic core window width dimensions thus are saved, magnetic core cost is not only saved, and reduce high-voltage pulse transformation Device leakage inductance, improves waveform transfer efficiency.
The secondary winding turns of transformer are evenly distributed in two magnetic poles for being wound on magnetic core, according to output voltage with secondary The number of turn increased principle, first coil of the half number of turn in proportion(Abbreviation low pressure bag)Insulation distance Δ 1 can design height The half of briquetting Δ 2,
Embodiment described above is only that preferred embodiment of the present utility model is described, not to this practicality New scope is defined, and on the premise of the utility model design spirit is not departed from, those of ordinary skill in the art are to this Various modifications and improvement that the technical scheme of utility model is made, all should fall into the protection of the utility model claims determination In the range of.
