Transformer Accessories

Transformer Radiators

Transformer radiators are heat exchangers designed to dissipate heat from transformer oil to the surrounding cooling medium. The oil absorbs heat from the windings and transfers it to the radiator, which increases the surface area exposed to the air, allowing the heat to dissipate. The function of a Transformer Radiator includes heat transfer from oil, oil circulation, cooling in the radiator, and the return of cooled oil to the transformer tank. These radiators are crucial for maintaining the transformer's temperature within safe limits, preventing overheating, enhancing the transformer's life by slowing down the aging process of insulating materials, improving reliability, and ensuring safety by preventing catastrophic failures. There are different types of cooling methods, including ONAN (Oil Natural Air Natural), ONAF (Oil Natural Air Forced), and OFAF (Oil Forced Air Forced), each suitable for different transformer sizes and operating conditions.

Transformer Oil Tanks

Transformer oil tanks, also known as conservator tanks, are cylindrical containers that provide space for the oil to expand and contract. The function of the Conservator Tank is to allow transformer oil to expand when hot and contract when cool, preventing overflow and ensuring efficient operation. The construction of a conservator tank includes a cylindrical tank with an inspection cover for maintenance, connected to the main tank via a pipe that prevents sludge from entering. There are different types of conservator tanks, such as Atmoseal Type Conservator and Diaphragm Sealed Conservator, each using different methods to separate oil from air, reducing the aging effect on the oil by preventing direct air contact.

In summary, Transformer Accessories, including radiators and oil tanks, play a vital role in the efficient and safe operation of transformers. They help maintain optimal operating temperatures, prevent overheating, extend the service life of transformers, and ensure reliable power supply. These accessories are indispensable for power distribution systems, providing adaptability to varying load conditions and ease of maintenance.
