Transformer fittings
It mainly includes iron core, winding, oil tank, oil pillow, insulating bushing, tap-changer and gas relay, etc. has its own unique characteristics:
core:
It is the magnetic circuit part of the transformer. It is stacked with high quality silicon steel sheets, to reduce hysteresis and eddy current loss. It is divided into two parts: iron core column and iron yoke, constitutes a closed magnetic circuit.
winding:Is the circuit part of the transformer, is divided into primary winding and secondary winding. The voltage is changed between the winding and the core by electromagnetic induction. The winding resistance and the insulation resistance between the winding and the iron core are important indicators to detect whether the transformer is damaged.
oil tank, oil pillow:
Used for storing and circulating transformer oil, for heat dissipation and insulation, to ensure the normal operation of the transformer.
