2025,01,02

The power transformer consists of two parts: the body and the accessories. The body is composed of coil, insulation, core, tap-changer, transformer oil and oil tank. The accessories of the transformer include oil storage tank, bushing, gas relay, pressure release device and thermometer. The coolers, insulating oils, bushings, tap switches, gas relays, pressure relievers and thermometers are all purchased from outside. The following is only a brief introduction to the manufacturing process of several main components.

1, coil winding: installation of winding skeleton - winding coil - wire connection - insulation - coil shaping - coil testing.

2, core assembly: silicon steel sheet cutting - deburring - stacked core - install pull plate and screen shield - binding core - core test - install core clips.

3, insulation processing: insulation cutting - deburring - corner - moisture-proof treatment.

4, oil tank and oil storage tank processing: steel plate cutting - oil tank and oil storage tank welding - rust removal - sand blasting - priming - painting - mechanical strength test.

5, the total assembly: install the core - install the oil tank pipe - set of coils - stack the iron yoke - install the tap changer - welding * connector - cover lead insulation - semi-finished product test - body drying - organizer body - oil tank assembly - accessories assembly - oil injection - sealing test - hot oil cycle - static release.
