Transformátory přijímají různé metody chlazení v závislosti na jejich kapacitě . Malé transformátory většinou přijímají samoobslužné (AN) nebo typy chlazení vzduchem (AF), spoléhající se na přirozenou vzduchovou konvekci nebo nucené vzduchové chlazení pro rozptyl tepla (one-iMers-coolling (On On On On On On On On On On On On On On On On) used. Large transformers adopt forced oil circulation air cooling (OFAF) or forced oil circulation water cooling (OFWF) systems. The core components of the cooling device include radiators, oil pumps, fans, oil flow relays, etc. The radiator is composed of multiple heat dissipation tubes and improves the cooling efficiency by increasing the heat dissipation area. The oil pump drives the insulating oil to circulate, carrying the heat generated by the windings and the core to the radiator. Fans accelerate air flow and enhance the heat dissipation effect. The temperature control system is equipped with multi-level temperature control devices, which automatically start and stop the cooling equipment based on the oil temperature to ensure that the transformer operates within the Optimální teplotní rozsah .
