Group.Wherein, secondary coil winding includes the coil windings that multiple groups have different the number of turns, provides different voltage outputs.According to line
The coil windings being wound around on coil rack 1 can be divided into high-voltage applications winding and low pressure by the difference of the occasion of circle winding application
Using winding.High-voltage applications winding uses insulated conductor coiling, uses insulated conductor coiling high-voltage applications winding in the present embodiment,
Using line copper conductor coiling low pressure applications winding.So that the multiwinding transformer of the present embodiment have it is good it is high pressure resistant formed,
Lesser volume, higher cost performance.High-voltage applications winding uses three layer insulation wire coiling as shown in Figure 8, including conductor wire
Core a1 and in having to the aramid layer a2, varnished a3, glass layer a4 being successively set on outside wire core a1 outside.It is poly-
Amide layer a2 is in golden yellow polyamide film, and thickness is only several microns, can bear the high voltage pulse of 1kV.Conductor wire
The sum of thickness of three insulating layers outside core is between 20-100 microns, and thickness is thin, and good insulation preformance, current density is big, adopts
There can be lesser volume with the multiwinding transformer of three layer insulation wire coiling.The insulating layer of three layer insulation wire has good insulation
Performance eliminates its insulating tape between adjacent coil windings, does not need to twine at them in coiling multiwinding transformer
Around insulating tape as barrier layer.It is same between them when the winding adjacent with high-voltage applications winding is low pressure applications winding
Setting insulating tape is not needed.Certainly, in order to improve the insulation performance of low pressure applications winding, the case where cost and volume allow
Under insulating tape can also be wound outside low pressure applications winding as barrier layer.In the present embodiment, it is only necessary in adjacent low pressure
Using insulating tape is wound between winding as barrier layer, save the cost saves volume.
