Industry Knowledge

An Oil Transformer is a type of electrical transformer that uses oil as the insulating medium. Oil-immersed transformers are commonly used in many applications, including power distribution, industrial processes, and renewable energy systems.
One of the main advantages of oil-immersed transformers is their high reliability and long lifespan. They are designed to operate in harsh environments and can withstand extreme temperatures and other environmental conditions.
However, oil-immersed transformers also have some disadvantages, including the risk of oil leaks and spills, which can pose environmental and safety risks, and the increased maintenance costs associated with oil changes and oil filtering.
Overall, oil-immersed transformers are a reliable and cost-effective solution for many applications, but their use is becoming increasingly limited due to the increasing demand for more environmentally friendly and efficient electrical power solutions.
The oil transformer works by using oil as an insulating and cooling medium.
Here's a basic overview of how it works:
Windings: The primary and secondary windings of the transformer are wound around the core, which is made of high-quality magnetic material. The windings are made of insulated wire, which is then immersed in oil.
Core: The core provides the magnetic circuit for the transformer, directing the flow of magnetic flux from the primary winding to the secondary winding.
Oil: The oil acts as an insulating medium, preventing electrical arcing and enhancing the transformer's reliability and safety. The oil also helps to dissipate heat generated by the transformer, keeping the windings and core at a safe temperature.
Cooling System: An oil-immersed transformer is designed with a cooling system, which circulates oil through the transformer to dissipate heat. The cooling system may include fans or other cooling components to help regulate the temperature of the transformer.
Operation: When electrical energy is supplied to the primary winding of the transformer, a magnetic field is generated, which induces a voltage in the secondary winding. The magnitude of the voltage in the secondary winding is proportional to the ratio of the number of turns in the primary winding to the number of turns in the secondary winding.
Output: The electrical energy is then output from the secondary winding, which is connected to the load. The load uses the electrical energy for its intended purposes, such as powering equipment or lighting.
Overall, the oil transformer works by using oil as an insulating and cooling medium to transfer electrical energy from the primary winding to the secondary winding. The oil helps to dissipate heat and prevent electrical arcing, enhancing the reliability and safety of the transformer.
