In figure, 1 tap-changing windings, 2 wires, 3 winding tops lift one's head wire, and wire is lifted one's head in 4 winding bottoms, 5 tap leads, 6 taps
Switch leads.
(5) detailed description of the invention
Accompanying drawing is a kind of specific embodiment of the present invention.This embodiment includes that tap-changing windings 1, tap-changing windings 1 are disposed in proximity to become
The position of depressor iron core principal post, tap-changing windings 1 is cylinder monolayer enwinding type structure.Tap-changing windings 1 uses some wires 2 arranged side by side
Coiling, a portion wire 2 is than residue another part wire coiling more than 21 circle.Tap-changing windings about 1 two ends connect respectively and set
Putting the labelled winding top of band and lift one's head wire 3 and wire 4 is lifted one's head in winding bottom, wire 3 and winding bottom are lifted one's head in winding top
It is connected with carrying labelled shunting switch lead-in wire 6 by tap lead 5 after the corresponding connection of wire 4 of lifting one's head.
Using a kind of transformer regulating winding construction of the present invention, tap-changing windings 1 is placed against transformer core principal post, adjusts
Pressure winding 1 structure is single layer cylinder formula structure, effectively reduces transformer body width when being placed on outermost, the most significantly
Degree improves tap-changing windings 1 direct-to-ground capacitance and longitudinal electric capacity, reduces self capacitive reactance, under overvoltage effect, to reducing pressure regulation
The electric field intensity of winding 1 and lead-in wire thereof has very important more practical value.Can use several during single layer cylinder formula winding technique
Wire 2 side by side, can according to design need be designed to two kinds of numbers of turn, i.e. a portion wire 2 and turn to N circle, another portion
Intraphase conductor 2 turns to N+1 circle, solves high-power transformer ratio error and is difficult to difficult problems such as meeting.Particularly as follows: tap-changing windings 1
For the single layer cylinder formula winding construction by 16 wires 2 coiling arranged side by side, wherein have 6 wires 2 to turn to N circle, 10 wires 2 around
Make N+1 circle；The upper and lower end parts of tap-changing windings 1 is lifted one's head the wire 2 of position and is used reliable improving bud grafting, to guarantee transformator
Test or running have and enough bears electrodynamic ability.According to transformator rated voltage and the tool of tapping range
Body numerical value, determines tap-changing windings 1 each tapping step number of turn N, according to GB1094.1 and technical protocol about the requirement of ratio error, really
The arrangement regulation of fixed each tapping step, tends to equal principle determine according to tap-changing windings 1 adjacent wires, adjacent tap voltage between lines
