S2, the uniform application releasing agent on reactor core mould, mould side is close to using upper ladder S windings by wire
Uniform coiling, reserves a section lead and makees coil low-pressure end lead-out wire；
If S3, repeating coiling dried layer to the regulation number of turns, wire end is drawn and makees high-pressure side lead-out wire；
S4, the coil that will be wound carry out vacuum drying, and drying temperature is set to 120-140 DEG C, is incubated 2-4 hours, air cooling
To room temperature, the demoulding；
S5, coil is polished according to drawing, be repaired, being smeared glass cement.
Further, the releasing agent be any one or one kind in hydrogeneous methyl-silicone oil, microcrystalline wax and talcum with
On mixture.
Further, in the step S2 winding process, when being ended up around to reactor Copper Foil/aluminium foil, insulating materials bag is used
Wire is covered, then overall around upper half lap prepreg tape, blend compounds water is cemented.
Further, the line length of the coil low-pressure end lead-out wire and high-pressure side lead-out wire is 0.3-0.5 meters.
Further, one layer of epoxy insulation varnish of the coil outsourcing.
Further, the coil uses copper enamel-cover strip conductor coiling.
The low-voltage series reactance coil winding technique that the present invention is provided has technique for coiling simple, production efficiency spy high
Point, can preferably ensure low-voltage series reactance product quality, at the same also improve machine winding turn-to-turn insulation quality and
Operational reliability.
