The main function of the transformer breather is to maintain the oil volume inside the transformer within the normal range and ensure the stability of the oil volume. Its main functions are: 1. Allow the oil to expand and contract freely when the temperature and load change. To maintain the stability of the oil volume; 2. Filter the air entering the transformer to prevent dust, moisture and other impurities from entering the oil, and protect the quality of the oil; 3. Reduce the pressure inside the oil tank by discharging gas; 4. Through breathing Circulation maintains the sealing state of the oil tank, reduces the entry of humid air, and prevents oxidation and aging of the oil.

Transformer breather (also called oil tank breather or oil tank ventilation device) is an important component of transformer equipment. Its main function is to maintain the oil volume inside the transformer within the normal range and ensure the stability of the oil volume. .
The following are several main functions of the transformer breather:
Oil volume adjustment: Since the internal oil volume of the transformer is closely related to changes in temperature and load, through the breather Its function allows the oil to expand and contract freely when temperature and load change to maintain the stability of the oil volume. This helps prevent oil or air bubbles from forming and reduces changes in internal pressure.
Protect the quality of the oil: Respirators usually have filters that can filter the air entering the transformer to prevent dust, moisture and other impurities from entering the oil, protect the quality of the oil, and Reduce oil volume contamination.
Prevent the explosion of the oil tank: When a fault or abnormality occurs inside the transformer, a large amount of gas (such as hydrogen) will be produced. The respirator can reduce the pressure inside the oil tank by discharging the gas. Avoid the risk of fuel tank explosion.
Maintain the sealing of the fuel tank: the respirator inhales external air when the oil volume expands, discharges the internal gas when the oil volume shrinks, maintains the sealing state of the fuel tank through breathing circulation, and reduces the loss of moist air Enter to prevent oxidation and aging of oil.
Generally speaking, the function of the transformer breather is to maintain the stability of the oil volume inside the transformer, protect the oil quality, reduce pressure changes, prevent the explosion of the oil tank, and maintain the sealing state of the oil tank. . These functions help ensure the normal operation of the transformer and extend the service life of the equipment.
