The Ultimate Guide to Oil-Filled Transformers

Oil-filled transformers, also known as oil-immersed transformers, are a critical component in electrical power systems. They are designed to efficiently transfer electrical energy between circuits, ensuring the stability and reliability of power distribution. This comprehensive guide will delve into the workings, benefits, and applications of oil-filled transformers, with a focus on the products offered by Zhejiang Shuntong Electric Co., Ltd.

How Do Oil-Filled Transformers Work?

Oil-filled transformers operate on the principle of electromagnetic induction. They consist of two or more coils of wire, known as windings, wound around a core made of magnetic material. The primary winding is connected to the input voltage source, while the secondary winding is connected to the output load.

The transformer is filled with a special type of oil, which serves multiple purposes. Primarily, the oil acts as an insulator, preventing electrical arcs and short circuits. It also aids in cooling the transformer by dissipating heat generated during operation.

Advantages of Oil-Filled Transformers

1. Thermal Shock Resistance: These transformers can withstand sudden temperature changes without compromising performance.

2. Overload Capacity: They can handle temporary overloads without significant damage.

3. Fire Resistance: The oil used in these transformers has high flame retardant properties.

4. Low Losses: They operate with minimal energy losses, ensuring high efficiency.

5. Low Partial Discharge: These transformers have a low capacity for partial discharge, which extends their lifespan.

6. Environmentally Friendly: They are free of hazardous gases and are safe for the environment.

Applications

Oil-immersed transformers are ideal for environments with high fire protection requirements, load fluctuations, and harsh conditions. Common applications include:
