Hey there! I’m a supplier of oil-immersed transformers, and today I wanna chat about how the oil in these transformers prevents oxidation. It’s a pretty important topic, ’cause oxidation can mess up the performance and lifespan of the transformer. Oil Immersed Transformer
First off, let’s understand why oxidation is a big deal. Oxidation of the transformer oil can lead to the formation of sludge and acids. These by – products can reduce the insulating properties of the oil, increase the operating temperature of the transformer, and even cause damage to the internal components. So, keeping the oil from oxidizing is crucial for the proper functioning of the transformer.
One of the main ways the oil in an oil – immersed transformer prevents oxidation is through the use of antioxidants. Antioxidants are like little guardians in the oil. They react with the oxygen before it can react with the oil molecules. There are different types of antioxidants used in transformer oil. For example, some common ones are phenolic antioxidants. These antioxidants work by donating a hydrogen atom to the free radicals that are formed during the oxidation process. By doing so, they neutralize the free radicals and stop the oxidation chain reaction.
Another important factor is the design of the transformer itself. The transformer is usually equipped with a conservator. The conservator is a small tank that is connected to the main transformer tank. It acts as a reservoir for the oil. The conservator has a diaphragm or a bladder that separates the oil from the air. This way, the oil is not directly exposed to the oxygen in the air. When the oil expands or contracts due to temperature changes, the diaphragm or bladder moves accordingly, allowing the oil to expand or contract without coming into contact with the air.
The quality of the oil also plays a huge role in preventing oxidation. High – quality transformer oil has better resistance to oxidation. When we, as suppliers, select the oil for our transformers, we look for oils that have a high flash point, low viscosity, and good dielectric properties. These oils are less likely to oxidize under normal operating conditions.
We also pay attention to the moisture content in the oil. Moisture can accelerate the oxidation process. So, we make sure that the oil is dry before it is filled into the transformer. We use special equipment to remove any moisture from the oil. And during the operation of the transformer, we have moisture – absorbing devices, like silica gel breathers. These breathers absorb the moisture from the air that enters the transformer, preventing it from getting into the oil.
Now, let’s talk about how we monitor the oxidation of the oil. We regularly take samples of the oil and test it for various parameters. One of the key tests is the measurement of the acid number. An increasing acid number indicates that the oil is starting to oxidize. We also check the dielectric strength of the oil. A decrease in dielectric strength can be a sign of oxidation. By monitoring these parameters, we can detect early signs of oxidation and take appropriate measures.
If we detect that the oil is starting to oxidize, we have a few options. One option is to add more antioxidants to the oil. This can help slow down the oxidation process. Another option is to replace the oil. In some cases, if the oxidation is severe, replacing the oil is the best solution.
