Description
Technical field
The present invention relates to a kind of design of transformer manufacturing, specifically a kind of interior screen using fractional turns integer winding connects
Continuous formula coil and its winding method.
Background technology
At present, power transformer inner screen continuous winding uses whole numbers of turns coiling more, i.e., the electric number of turn of every section line cake is equal
For integer.It is then turn-to-turn coiling to shield line, that is, shields line and be wound between two circles, and general using across two sections of screens or across four sections of screens.For
Reduction turn-to-turn field strength, to shield the turn insulation of line can accordingly thicken.And for the less coil of every section of number of turn, every section of screen number of wire turns is certainly
It is so also less.Just need to increase the hop count of interior screen section to increase longitudinal electric capacity of coil, the coiling for being so increased by coil is difficult
Degree.
The content of the invention
It is low for thicker, the few circle section filling rate of screen turn(s) insulation of power transformer inner screen continuous winding in the prior art
And every section of number of turn of coil it is less when interior screen section it is more and the deficiencies of increase coiling difficulty, the problem to be solved in the present invention is to provide one
The number of turn of kind increase screen line while every section of work number of wire turns is not increased, the turn insulation of appropriate reduction screen line, and improve coil
Filling rate the inner screen continuous winding and its winding method using fractional turns integer winding.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of inner screen continuous winding using fractional turns integer winding of the invention, there is active line and screen line, active line
For two wires of parallel coiling, screen line is located between active line turn-to-turn and line.
In the thread-changing fragment position of active line, the active lines of two parallel coilings rises to after a circle next again more than one
Section, another directly rises to next section, forms the structure that integer adds half turn.
Cancel the filling insulating part of turn-to-turn.
A kind of winding method of inner screen continuous winding using fractional turns integer winding of the invention, has active line and screen
Line, active line use two parallel coilings of wire, and screen line is using two and around will shield line and be put between active line turn-to-turn and line together
When coiling, every section of coil screen number of wire turns at least doubles.
In the thread-changing fragment position of active line, the active lines of two parallel coilings rises to after a circle next again more than one
Section, another directly rises to next section, and two in next section of parallel coiling again.
Cancel the filling insulating part of turn-to-turn；Shield turn(s) insulation thickness and reduce 20%；The hop count of interior screen section reduces 30%.
The invention has the advantages that and advantage：
1. coil of the present invention carries out coiling using two wires (being mostly composite conductor or transposed conductor), every section of number of turn is no longer
Whole numbers of turns is confined to, half turn situation can suitably be occurred by being calculated according to product, i.e. integer adds the situation of half turn, effectively carries
The high filling rate of coil, reduces coil cost.
2. in the present invention, when coil uses two wire coilings, screen line can equally use two and around will shield line
Coiling simultaneously is put between turn-to-turn and line, and the screen number of wire turns of so every section coil at least adds one times, effectively increases coil
Longitudinal electric capacity, the turn insulation thickness for shielding line also can be accordingly smaller.
3. the present invention can reduce the hop count of interior screen section in the case of longitudinal electric capacity identical, coiling difficulty is reduced, particularly
For larger and every section of number of turn of electric current, relatively small number of coil, above-mentioned both sides improvement effect become apparent again, and filling rate increases
The anti-short circuit capability of coil is enhanced while adding again.
Brief description of the drawings
Fig. 1 is the coiling schematic diagram of the inner screen continuous winding of fractional turns integer coiling of the present invention.
Wherein, 1 is active line, and 2 be screen line.
Embodiment
With reference to Figure of description, the present invention is further elaborated.
A kind of inner screen continuous winding using fractional turns integer winding of the invention, there is active line 1 and screen line 2, work
Line 1 is two wires of parallel coiling, and screen line 2 is located between active line turn-to-turn and line.
In the thread-changing fragment position of active line 1, the active lines of two parallel coilings rises to after a circle next again more than one
Section, another directly rises to next section, forms the structure that integer adds half turn.
The winding method of the above-mentioned inner screen continuous winding using fractional turns integer winding, there is active line 1 and screen line 2,
Active line 1 uses two parallel coilings of wire, and screen line 2 is using two and around will shield line 2 and be put between the turn-to-turn of active line 1 and line
Coiling simultaneously, every section of screen number of turn of line 2 of coil at least double.
In the thread-changing fragment position of active line 1, the active lines of two parallel coilings rises to after a circle next again more than 1 one
Section, another directly rises to next section, and two in next section of parallel coiling again.
Present invention eliminates the filling insulating part of turn-to-turn, screen line 2 turn insulation thickness reduces 20%, and the hop count of interior screen section is reduced
30%.
As shown in figure 1,1~16 section is interior screen section, fractional turns integer coiling, the number of turn is 3.5 circles, between screen line 2 is online (as
Between the wire of first paragraph 1 and 1 ') and turn-to-turn (as between first paragraph 1 ' and 2 wires) while coiling, the 17th section uses whole numbers of turns coiling,
The number of turn is 4 circles.It is same for being somebody's turn to do and Conventional coil then generally use whole numbers of turns coiling, screen line 2 are also typically placed in turn-to-turn coiling
Accompanying drawing, the 17th section still uses 4 circle coilings, and to ensure the radial size of coil without departing from the 17th section, the 1st~16 mask segments can only just adopt
With 3 circle coilings, so to ensure that the identical mask segments of the radial size of coil just need to be filled with insulating paper lath, and shield line
Also can only the circle of coiling 2.The filling rate of coil is effectively improved using the coil of fractional turns integer coiling by contrast, shields line segment
The number of turn also increase 6 circles by 2 original circles, add longitudinal electric capacity of coil, the screen turn insulation of line 2 also can accordingly be thinned,
According to primary Calculation, screen line 2 turn insulation thickness can decline 1.65 or so from 3.95, and the hop count of interior screen section can reduce to 16 sections of left sides by 24 sections
It is right., will using fractional turns integer winding because sectional area of wire is larger for those high currents and the less coil of every section of number of turn
The effect of filling rate and the longitudinal electric capacity of raising to coil becomes apparent, also more cost-effective, the anti-short circuit capability of coil
Further enhance.
