During the operation of a transformer, insulation and cooling technologies for the core are of paramount importance, as they directly dictate the transformer's performance, efficiency, and service life. Superior insulation properties effectively prevent short circuits and electrical leakage, while efficient cooling measures ensure the core maintains a stable temperature under high load, preventing performance degradation and damage caused by overheating.
Cooling technologies are achieved through various methods. Primarily, the design of the transformer core accounts for airflow; through rational structural design, air is allowed to circulate freely around the core to carry away heat. Furthermore, large-scale transformers often employ cooling systems, such as fan cooling or oil-immersed cooling. These systems effectively reduce the core temperature, ensuring stability under high-load conditions. Oil-immersed cooling is a prevalent method where the core is submerged in specialized cooling oil. Utilizing the oil's high thermal conductivity and fluidity, heat is rapidly transferred to the transformer casing and subsequently dissipated into the air via radiators.
