Description
Technical field
The utility model is related to technical field of electric power detection, and in particular to a kind of segmented high pressure voltage regulation coil.
Background technology
Conventional helical formula coil transposition complex process, transposition easily causes turn-to-turn short circuit during coil press mounting, and
Transposition is incomplete, increases added losses, such as Fig. 1,1~No. 8 is to the name of each wire, and connecing tap switch with later stage lead has
It closing, such as Fig. 2, I enlarged diagram is 8 conducting wires accumulation coiling forms, and 1 and 2 are close to round paper tube and stay in bottom, 7 and 8
In outermost, 8 lines pitch of the laps together, from the sped structure it can be seen that there is following defect：
1, transposition is incomplete, and replace complex process, more to the limitation of coil line gauge type selecting, due to longitudinal leakage field induction
It is unevenly distributed and causes added losses that must increase；
2, due to fault of construction, voltage difference is larger between the wire turn on the adjacent tap position of conventional helical formula coil, if grade
Voltage reaches 2.5kV, and voltage will be considerably beyond defined turn insulation work field strength 2kV/mm between wire turn；
3, under the premise of considering cost, traditional helical winding width is relatively low to oil duct radiating efficiency.
Pressure regulation tap wire turn-to-turn step voltage difference is larger, and security reliability is still cannot be guaranteed in the case of turn insulation 1.95mm, therefore
Layer-type winding is appropriate, and tap layer is separated with interlayer with oil duct, the reduction step voltage that not only solved heat dissipation problem again it is poor it is larger caused by
Insulation breakdown risk, but common multilayer layer-type winding, when one timing of the number of plies, each layer the number of turns increases, and interlayer operating voltage is high, interlayer
Insulation thickens, and coil width is made to increase to size.
Utility model content
Purpose of utility model：For overcome the deficiencies in the prior art, the utility model provides a kind of segmented high pressure pressure regulation
Coil, this kind of loop construction can improve voltage regulation coil field strength distribution, reduce the placement quantity of layer insulation, reduce width to size
It is cost-effective, coil added losses are reduced, the voltage difference reduced between adjacent turns improves breakdown characteristics, improves radiating efficiency.
Technical solution：Segmented high pressure voltage regulation coil described in the utility model, the coil use graded winding structure,
The graded winding by 8 layer by layer formula coil form, the layer-type winding includes upper and lower two parts, wherein upper layer layer-type winding
It connects with lower layer's layer-type winding.
Preferably, go out a tail portion tap after each described upper layer layer-type winding coiling n circle, go out the portion
It is connected with the end tap of corresponding lower layer's layer-type winding after connector.
Preferably, each described layer-type winding can flexibly arrange out different the number of turns.
Preferably, the tap layer of each layer-type winding is separated with interlayer with oil duct.
Advantageous effect：Compared with prior art, remarkable advantage is the utility model：1, this coil uses segmented line
Circle, is composed in series by several layer-type windings, and interlayer operating voltage reduces half, makes the turn insulation of coil, layer insulation and layer in this way
Between voltage it is close with general multilayer layer formula coil；2, in layer-type winding structure, tap layer is separated with interlayer with 4mm oil ducts, is both solved
Certainly heat dissipation problem reduce again step voltage difference it is larger caused by insulation breakdown risk；3, each layer can be arranged out flexibly different
It is identical or meet the requirement for the various pressure regulation difference datas that user is proposed can to meet every grade of voltage difference for the number of turns.

Specific implementation mode
The utility model provides a kind of segmented high pressure voltage regulation coil, due to the coil direct-to-ground capacitance very little, series electrical
Appearance is very big, therefore can not only improve Impulse Voltage descender line and enclose beginning voltage's distribiuting, moreover it is possible to effectively eliminate and inhibit each
The harm that kind of overvoltage oscillations insulate to coil, and under the premise of not increasing coil width and not increasing product cost to thickness,
Make the turn insulation of coil, layer insulation, interlayer operating voltage is close with general layer-type winding, and greatly improves the heat dissipation of coil
Effect.The loop construction uses graded winding, and graded winding is composed in series by several layer-type windings, single line around one layer,
So interlayer operating voltage reduces half, there is no the big problems of voltage difference, make the turn insulation of coil, layer insulation and interlayer in this way
Voltage is close with general multilayer layer formula coil.
It is specific as shown in figure 3, the coil by 8 layer by layer formula coil form, every layer of layer-type winding is by upper and lower two laminars again
Coil is connected in series, and in respectively Fig. 3 1. and 2., such as Fig. 4, the series system between upper and lower two layer-type windings is on each
Go out a tail portion tap after formula coil winding n circles layer by layer, gone out after the tap of tail portion with the end of corresponding lower layer's layer-type winding
Partial joints connect, and the pigtail connection of each lower layer's layer-type winding distinguishes tap switch, and the number of turns of coil winding is not fixed, each
Layer can flexibly arrange out different the number of turns, and it is identical or meet what user was proposed can to meet every grade of voltage difference
The requirement of various pressure regulation difference datas.
The 4 of thiol are oil duct thickness, and it is 4mm generally to use thickness, which had not only solved heat dissipation problem but also reduced grade
Insulation breakdown risk 5 caused by voltage difference is larger is the thickness of every layer line circle, outer stay of arranging on the coil that coiling is completed, 6
The thickness of coil stay is represented, the insulation width of coil is 47mm, and the insulation width of upper and lower two layer-type windings is identical.
