Description
Technical field
The present invention relates to a kind of technical field of transformer manufacturing, specially a kind of low reactance height cake formula tap-changing windings.
Background technique
In large capacity loaded voltage-regulating electric transformer, voltage-regulating winding structure form is mostly spiral or drum type brake, and is arranged
It is listed in outermost, is convenient for the wiring of pressure regulation lead.When other winding voltage grades height, when voltage regulation coil is as outermost lateral coil, need
Winding construction, which is adjusted, according to the outlet method of high-voltage winding or changes the modes such as arrangement position is wanted with meeting stringent insulation distance
It asks.
Spiral or drum type brake tap-changing windings, reactance height are influenced by pressure regulation tapping step number and tapping range, and adjustability is small；
In the winding arrangement structure that tap-changing windings outermost is placed, when high-voltage winding is using the radial outlet in end, the electricity of tap-changing windings
Anti- excessive height can accordingly cause the reactance excessive height of high-voltage winding, meet insulation distance with this.The excessively high reactance of winding
Height causes transformer whole height not to be able to satisfy the requirement of shipping height, thus cannot achieve this type transformer device structure and set
Meter.
Summary of the invention
For in large capacity loaded voltage-regulating electric transformer in the prior art the outlet of high-voltage winding end and tap-changing windings
End is difficult to the deficiencies of meeting insulation distance requirement, and the problem to be solved in the present invention is to provide a kind of low reactance height cake formula pressure regulation
Winding.
In order to solve the above technical problems, the technical solution adopted by the present invention is that:
A kind of low reactance height cake formula tap-changing windings of the present invention, are placed in outermost, each to tap the radial outlet of connector；
High-voltage winding is arranged on the inside of tap-changing windings, the radial outlet in end.
Tap-changing windings are cake formula structure, are divided into tap-changing windings top and tap-changing windings lower part two parts, tap-changing windings top
It is consistent with line cake the number of turns of tap-changing windings lower part, around to opposite.
In tap-changing windings top and tap-changing windings lower part, every part all has the identical multiple line cakes of quantity, every two line
Cake is level-one, the tap of adjacent two-stage lift one's head lead-out wire head and the tail connect.
The upper and lower symmetric parallel of every group of line cake draws tap and lifts one's head, and fixed fanning strip is placed at the tap place of lifting one's head.
Total cake number of tap-changing windings by pressure regulation tap series number determine.
Each tap is lifted one's head places arrester as needed.
The invention has the following beneficial effects and advantage:
1. the present invention enriches tap-changing windings and is placed on outermost loop construction form, this coils arrangement form is realized
Power transformer high-voltage winding end radial outlet method, it is easily operated.
2. the present invention by adjusting every cake coil turn, in two cakes realize level-one pressure regulation tap extraction, realize compared with
Low winding reactance height.

Specific embodiment
The present invention is further elaborated with reference to the accompanying drawings of the specification.
A kind of low reactance height cake formula tap-changing windings of the present invention, are placed in outermost, each to tap radial outlet of lifting one's head；
High-voltage winding 102 is arranged in 101 internal side diameter of tap-changing windings, the radial outlet in end.Tap-changing windings 101 are cake formula structure, are divided into tune
Press winding top 105 and 106 two parts of tap-changing windings lower part, the line cake circle on tap-changing windings top 105 and tap-changing windings lower part 106
Number is consistent, around to opposite；In tap-changing windings top and tap-changing windings lower part, every part all has the identical multiple line cakes of quantity,
Every two line cake is level-one, and the Winding tap lead-out wire head and the tail of adjacent two-stage connect.
As shown in Figure 1, tap-changing windings 101 are arranged in outermost in the present embodiment, it is each to tap radial outlet of lifting one's head.High pressure
Winding 102 is arranged in tap-changing windings internal side diameter, the radial outlet in end.High-voltage winding end uses radial outlet, can be to avoid height
It extrudes line apparatus etc. and the destruction in structure is caused to insulating parts such as transformer pressing plates, to reduce its mechanical strength and be resistant to short
Road ability.The insulation distance 103 of high-voltage winding 102 end outlet to 101 end of tap-changing windings requires strictly, tap-changing windings 101
Reactance height be determine this insulation distance 103 key factor.
As shown in figures 2-3, tap-changing windings of the present invention are under cake formula structure, including tap-changing windings top 105 and tap-changing windings
Portion 106, tap-changing windings top 105 is identical as 106 line cake quantity of tap-changing windings lower part, and positive and negative section 104 of each winding wire cake is
Level-one, the tap-changing windings of adjacent two-stage lead-out wire 107 of lifting one's head connect from beginning to end, tap-changing windings top 105 and tap-changing windings lower part 106
Lead-out wire parallel connection of lifting one's head formed tap-changing windings top and the bottom it is in parallel after lead-out wire 108；Whole winding top and the bottom line cake the number of turns is symmetrical,
Around to opposite.Place oil duct between adjacent two lines cake, top and the bottom tap-changing windings, which are lifted one's head, places fixed sector at lead-out wire 107
Plate.Arrester 109 can be placed as needed between lead-out wire 108 after tap-changing windings top and the bottom are in parallel.
Total cake number of tap-changing windings is determined by the number of tap series quantity, in the case where number of taps is more, compared to
Spiral or drum type brake winding construction, greatly reduces the reactance height of winding.
