Liquid-immersed Transformers are used in combination with an insulating oil to eliminate the waste heat through the transformer windings

Around the world, liquid immersed transformers (LIT) are employed in a wide range of applications. These devices are quite beneficial and can be used on their own or in conjunction with Forced Air Furnaces to create a more efficient system. The best way to think about this type of transformer is to relate it to a standard forced air winding, except that instead of pushing air into the windings, they are submerged in liquid. While the two have numerous differences, they do share some similarities, such as a variable speed drive system that provides for more control, a lower cost per unit, and damping resistance.In addition, they both use electrical energy and can be used in applications where power is not readily available, such as on inland railways.

In the past, air-cooled transformers, also known as forced air windings, were the most prevalent type of liquid-immersed transformer (F Wag). While these devices performed admirably in the creation of air-conditioned spaces, they were prone to failure due to a lack of sealing. As a result, air cooling in the windings became necessary, and the cooling impact began to affect the device's operation. When water is introduced to the lubricant, the latest liquid-immersed transformers tend to perform much more successfully. As a result, even when operating at maximum capacity, the system will function significantly better.

 

Liquid-immersed transformers are divided into two categories. Class I uses oil pumps as a driving mechanism, whereas class II uses electric motors with water-based drives. There are also a number of hybrid versions available that combine the benefits of both liquid cooling methods. These units are made up of two chambers separated by a sealed tube.

The procedure begins by heating the pump to a certain temperature, which can range from a few hundred degrees above ambient temperature to well over a thousand degrees. It is then directed into the first chamber of the unit after this temperature has been reached. After that, the air-cooled component is inserted between the two. At this point, it's worth noting that liquid-immersed transformers don't have fans. To deliver heat to the air-cooled pump, they use air and oil heaters instead.

 

Cooling is the second stage. After the heating process is complete, the liquid-immersed transformers are placed in the device's second chamber and the cooling process begins. Before being discharged into the next step of the cooling cycle, air is pumped through the tubes and passes through a series of filters, where tiny particulates can be removed. The filters can be built to meet the needs of the manufacturer as well as the needs and specifications of the application. This cycle is repeated until there is enough cool air in the distribution transformers.

There are a variety of cooling and/or heating options for liquid-immersed transformers, depending on the manufacturer. While hot water and/or steam are being used, some of these systems have a cold plug that provides for quick access to the chilly side of the system. There are other methods that make installing hot and cold plug applications simple. In addition, some distribution transformers have a built-in microwave that can be turned on or off manually. These systems frequently include a microcontroller that is programmed to turn on and off as needed to ensure maximum efficiency.
