Participation reward: 2 Wealth. Reward for correct answer: 9 Wealth. Question: Why are transformers in small containers not equipped with oil pillows?
There are two main purposes for the oil used in oil-immersed transformers: one is to regulate the amount of oil, ensuring that the transformer tank is always filled with oil； Second, reduce the contact surface between oil and air to prevent the oil from oxidizing and getting damp. The voltage level is low, the contact area between oil and air is small, and sealing is easy.
Because the other voltage levels are lower, the contact area between oil and air is small, and sealing is easy.
The voltage level is low, the contact area between oil and air is small, and sealing is easy
Q&A: Why don’t small-capacity transformers have oil conservators? Answer: There are two main purposes for installing an oil conservator in an oil-immersed transformer: one is to regulate the amount of oil, ensuring that the transformer tank is always filled with oil ； Second, reduce the contact surface between oil and air to prevent the oil from oxidizing and getting damp. Because transformers in small containers have a lower voltage level, the contact area between oil and air is small, and sealing them is easy. Therefore, transformers in small containers are not equipped with oil pillows.

There are two main purposes: one is to regulate the oil level, ensuring that the transformer tank is always filled with oil； Second, reduce the contact surface between oil and air to prevent the oil from oxidizing and getting damp. Another reason is that at other voltage levels, the contact area between oil and air is smaller, and sealing is easier.
