Background
The oil immersed transformer is usually filled with transformer oil in an oil tank of the transformer, and the transformer oil can play a role in insulation and cooling. Insulation function: the insulating capacity of the transformer oil is far greater than that of air, so that current can be prevented from directly flowing between the winding and other conductors, and accidents such as electric arc and electric shock are prevented; cooling effect: when the transformer works, a certain amount of heat is generated, the transformer oil can absorb and conduct the heat as a cooling medium, and the heat is taken away and emitted to the surrounding environment through circulation flow, so that the temperature of the transformer is kept within a safe range.
When the transformer operates, the temperature of the transformer oil can change along with the change of load and environmental temperature, so that the volume of the transformer oil expands with heat and contracts with cold, the liquid level of the transformer oil changes, when the liquid level of the transformer oil is too high, the internal pressure of the oil tank is increased, and the deformation of the oil tank or the ejection of oil can be caused; too low a transformer oil level can lead to reduced insulation inside the transformer, possibly causing insulation breakdown or gas protection actions.
