Vertoro regulation also wants continuous firing to power for a period of time with proof load in the case where losing cold (fan does not turn), for
Main heater element transformer in vertoro reduces the fever of transformer using the method for reducing winding current density more
Amount.Main screw lift can so be increased.Problems of the prior art：Effect of the vertoro in no paralleing reactor
Under, every group of rectifier bridge output current degree of unbalancedness is big, and vertoro main screw lift weight can be then made plus paralleing reactor.For
It is negative to ensure for a period of time that the requirement of airborne vertoro wants continuous firing in the case where losing cold (not having forced ventilation)
Power supply is carried, this requires the winding current density value on the Primary Component isolating transformer in vertoro is low, but this meeting
Increase vertoro main screw lift.
The content of the invention
The purpose of the present invention：Winding technique side of the invention by varying the multi-winding isolation transformer in vertoro
Method, so as to make vertoro device also to make every group of rectifier bridge output current more equal under the action of no paralleing reactor
Weigh, while improve the heat dispersal situations of transformer winding in the case where not reducing multi-winding isolation transformer winding current density.
Technical scheme：A kind of winding method of civil aviation multi-winding isolation transformer, the method are taken
Following steps：
1) copper foil winding one is wrapped in the outside of multiwinding transformer skeleton, first as multi-winding isolation transformer
Layer winding；The width of copper foil winding two is less than the width of copper foil winding one, outside the first layer winding of multi-winding isolation transformer
Side winding copper foil winding two；The width of copper foil winding three is less than the width of copper foil winding two, the of multi-winding isolation transformer
Winding copper foil winding three, completes the coiling of line winding on the outside of double-layer winding；
2) it is connected according to three groups of line windings of method coiling of step 1, the first layer winding first and last of three groups of line windings, makees
For the secondary delta windings of multi-winding isolation transformer；The end of the second layer winding of three groups of line windings is connected, as more
The primary side star winding of winding isolation transformer；The end of the third layer winding of three groups of line windings is connected, as Multiple coil every
From the secondary star winding of transformer.
Advantages of the present invention：By the way that the secondary triangle shape winding of multi-winding isolation transformer is placed on first layer, primary side
Winding is placed on the second layer, and secondary star shape winding is placed on third layer, and this coils arrangement mode can make in vertoro device
Every group of rectifier bridge output current reach more balanced state, without install paralleing reactor, realize that main screw lift subtracts
Light purpose.Method by successively decreasing to each layer winding of multi-winding isolation transformer (copper foil winding) width, makes every layer of winding all
There is the naked place being exposed on the external, can so improve the radiating condition of multi-winding isolation transformer itself, so as to fulfill product weight
Measure the purpose mitigated.
