What is the purpose of a breather in a transformer?
1 Answer
In the context of transformers, a "breather" typically refers to a device or component used to manage the pressure changes and the exchange of air within the transformer's oil-filled tank. Transformers generate heat during their operation, which can lead to the expansion and contraction of the insulating oil inside the tank due to changes in temperature. This, in turn, causes pressure variations within the tank.
The purpose of a breather is to regulate these pressure changes and prevent moisture and contaminants from entering the transformer. It consists of a container filled with a desiccant material (often silica gel) that absorbs moisture from the incoming air. As air flows in and out of the transformer tank due to temperature fluctuations, the breather allows the air to pass through the desiccant material, effectively removing moisture from the air before it enters the transformer.
By maintaining a dry and clean environment within the transformer tank, breathers help extend the lifespan of the insulating oil and prevent the degradation of the transformer's insulation. This, in turn, contributes to the overall reliability and efficiency of the transformer's operation. Breathers are important components in power transformer systems to ensure proper functioning and longevity of the equipment.
