Some oil-immersed transformers can be fitted with tap changers, but not all models support this feature.

To extend the service life of oil-immersed transformers, proper maintenance methods and measures are crucial.

The oil level should be maintained between 1/4 and 3/4 of the mark on the oil level gauge (refer to GB/T 6451-2015 standard).

Using mineral insulating oil as the cooling and insulating medium, it can stably withstand long-term overload operation, has better resistance to shor

The core is the magnetic circuit part of the transformer. During operation, it generates heat due to hysteresis and eddy current losses.

The operating voltage of a power transformer should generally not exceed 105% of the operating tap voltage, and must not exceed the system's maximum o

In operation, the heat from the windings and core of an oil-immersed power transformer is first transferred to the oil, and then through the oil to th

Except for small-capacity transformers using copper conductors, the low-voltage windings of oil-immersed transformers generally employ a cylindrical s
