- Commodity name: Triangle Transformer
The upper and lower iron yokes are made of insulating cardboard; the balance pad is made of laminated wood for insulation; the lead bracket is made of laminated paper; all the fasteners are effectively locked lock nuts.
Structural Features
Iron core: cold-rolled silicon steel sheet with material performance no less than 30ZH120; three-phase three-column three-dimensional symmetrical structure with a balanced three-phase magnetic circuit; each group (coil) of chips is wound by thin steel strips on a special iron core winding machine, The pressure is uniform and compact; the iron core frame sheet is vacuum annealed to eliminate stress and improve electromagnetic performance; the surface of the iron core is coated with epoxy resin to prevent moisture and cure.
Winding: paper-coated flat copper wire or QQ-2 acetal enameled round copper wire made of low-oxygen copper; low-voltage coils are double or four-layer round copper or new spiral or foil type. The high-voltage coil is a multi-layer cylindrical type; the coil oil channel is a corrugated structure, and the interlayer insulation is double-sided dispensing paper; the low-voltage and high-voltage surfaces are coated with epoxy resin semi-adhesive glass fiber tape to increase mechanical strength.
Body and lead: the upper and lower iron yokes are made of insulating cardboard; the balance pad is made of laminated wood for insulation; the lead bracket is made of laminated paper; all the fasteners are effectively locked lock nuts.
Fuel tank: a fully sealed corrugated fuel tank with a triangular structure. Corrugated sheets are provided for all three phases to ensure heat dissipation and compensate for the expansion and contraction of the oil volume with the change of oil temperature; the tank cover is equipped with an oil level gauge with a pressure release valve for convenience Refueling and observing the height of the oil level, as well as safety protection for the release of pressure in the event of a sudden fault and overvoltage inside the transformer.
