Structural features
1.S13-M- transformer core: the use of material properties of not less than 30ZH120 cold-rolled silicon steel; three-phase three-column three-dimensional
symmetrical structure of the most balanced three-phase magnetic circuit; each group (volume) In dedicated iron Heart winding machine on the system, the pressure
evenly compact; core frame by vacuum annealing treatment to eliminate stress, improve electromagnetic performance; core surface coated with epoxy paint, moisture,
curing.
2.S13-M- transformer windings: the use of low-oxygen copper material paper drum flat wire or QQ-2 acetal enamelled round copper wire; low voltage coil for the
double or four round copper or new spiral, Or foil. High voltage line Ring for the multi-layer cylinder; coil oil for the corrugated structure, interlayer insulation for the
double-sided adhesive tape; low pressure and high pressure surface are added around the epoxy resin semi-viscous fiberglass belt, increase the mechanical strength.
3.S13-M- transformer body, leads: the use of insulating cardboard made of upper and lower iron yoke insulation; the use of laminated wood production balance pad
insulation; the use of laminated cardboard for the lead bracket; all fasteners are Effective locking nuts.
4.S13-M- transformer oil tank: the use of triangular structure of the whole sealed corrugated fuel tank, three-phase are set to provide heat dissipation and
compensation with the oil temperature changes caused by changes in the volume of oil volume expansion; The oil level gauge with pressure relief valve on the cover is
easy to refuel and observe the oil level, and the pressure protection is safe when the internal fault of the transformer is overvoltage.
