Two adjacent line cakes.
Further, wire of the line cake by some circles around the second insulating cylinder is constituted, and coiling is more on single second insulating cylinder
Individual line cake.
Further, the first insulating cylinder and the second insulating cylinder surface are provided with the first insulation cured layer.
Further, the first insulation cured layer is set to the first insulating lacquer layer.
Further, surface is provided with the second insulation cured layer.
Further, the second insulation cured layer is set to the second insulating lacquer layer.
Further, the whole height of some second insulating cylinders is equal to the height of the first insulating cylinder.
A kind of manufacture method of modular coil, including：Step one, makes the first insulating cylinder, Ruo Gan by design size
Two insulating cylinders；Some second insulating cylinders are socketed the first insulating cylinder, and it are smooth to fix two ends by step 2；Step 3, will be fixed
The first insulating cylinder well, the second insulating cylinder immersion insulated paint, then dry, make the first insulating cylinder, the second insulating cylinder completely insulated simultaneously
Solidification connection；Step 4, uniformly around wire processed on the second insulating cylinder, some circle wire group being aligned cakes, the multiple line cakes of coiling,
And it is evenly spaced with cushion block between adjacent two lines cake；Step 5, after some second insulating cylinder whole coiling line cakes, vacuumizes leaching
Paint, then baking and curing make the first insulating cylinder, the second insulating cylinder, line cake and cushion block shape integral, to resist wire when being powered
Active force.
The invention has the beneficial effects as follows：Simple structure, easy making process；Solidified by the structure of the little cylinder of big jacket casing, then dipping lacquer
It is integrated, is all to be not less than single complete insulating cylinder in terms of intensity and electric insulation, with respect to single complete insulation
Cylinder is without any defect；In later maintenance, multiple coil modules can be disassembled into, modular repair and replacing is carried out, is solved
The predicament all disassembled, while also not interfering with intac wire；And when product is in remote region, can be without inciting somebody to action
Whole transformer transporting goes back to plant area and is keeped in repair, and directly targetedly produces coil module, after transport to scene, carries out office
Portion's changing of coils, is saved greatly the cost of maintenance, also shortens the cycle of maintenance.
