Coil Core Oil Filled Transformer

Structure Characteristics

Iron core: the material performance is not lower than 30ZH120 cold-rolled silicon steel sheet; the three-phase three-column three-dimensional symmetric structure has the most balanced three-phase magnetic circuit; each group (roll) chip is wound by a thin steel strip on a special core winding machine. The pressure is even and firm; the core frame is vacuum annealed to eliminate stress and improve electromagnetic performance; the surface of the core is coated with epoxy paint, moisture proof and solidified.

Winding: paper-coated copper flat wire made of low-oxygen copper or QQ-2 acetal enamelled round copper wire; low-voltage coil is double-layer or four-layer round copper or new spiral, or foil type. The high-voltage coil is a multi-layer cylinder; the coil oil passage is corrugated, the interlayer insulation is double-sided adhesive paper; the low-pressure and high-pressure surfaces are coated with epoxy semi-adhesive glass fiber belt to increase mechanical strength.

Body and lead: Insulating cardboard is used to make upper and lower iron yoke insulation; laminated wood is used to make balance pad insulation; laminated paper is used as lead support; all fasteners are effective locking locknuts.

Oil tank: Fully sealed corrugated oil tank with triangular structure, corrugated sheets are provided in three phases to ensure heat dissipation and compensate for the expansion and contraction volume of oil volume change with oil temperature change; oil level gauge with pressure relief valve on the cover surface is convenient refueling and observing the oil level, and releasing pressure safety protection against sudden fault overvoltage inside the oil filled water cooled transformer.

Performance Features

1. Energy saving: the no-load loss is reduced by 40%-50%, and the load loss is reduced by 7%-10%;

2. Reduce line loss: the no-load current is reduced by more than 90%;

3. Ultra-quiet: the noise is reduced by 10-15 decibels;

4. No interference: the magnetic flux leakage is reduced by more than 50%;
5. Saving raw materials: the cost of copper and iron is reduced by 20%-30%;
6. Significant economic benefits: The cost of ten years of substation is down 17.2% from the generation oil filled transformers.

Storage Instructions

When the oil filled transformer is stored, the oil level of the fully sealed transformer should be kept 2~3cm below the cover, and the storage condition should be checked regularly. For the transformer to be transported by the oil conservator, the oil conservator must be installed to ensure a certain amount of oil pressure and oil, to meet the needs of its temperature change, and the seal of the three phase distribution transformers must be protected during storage.
