Oil-immersed transformers, also known as liquid-filled transformers, are transformers that use oil as a cooling and insulating medium. There are several different types of oil-immersed transformers based on their construction and application. Here are some of the common types:
- Power Transformers
These transformers are designed to handle high voltage and power levels. They are used in power generation plants, substations, and large-scale industrial applications.
- Distribution Transformers
Distribution transformers are used to step down high voltage from power transmission lines to lower voltage levels suitable for distribution to residential, commercial, and industrial areas.
- Pad-Mounted Transformers
These transformers are designed for outdoor installation on a concrete pad. They are commonly used in urban areas where space is limited, such as residential neighborhoods or commercial centers.
- Pole-Mounted Transformers
Pole-mounted transformers are mounted on utility poles and are used for distributing power in rural areas or along power distribution lines.
- Substation Transformers
Substation transformers are installed in electrical substations and play a crucial role in the transmission and distribution of electricity. They step up or step down voltage levels as needed.
- Autotransformers
Autotransformers have a single winding that serves both the primary and secondary sides of the transformer. They are more compact and efficient compared to conventional transformers and are commonly used in applications where voltage conversion is required.
- Unit Substation Transformers
Unit substation transformers combine a transformer, high-voltage switchgear, and low-voltage switchgear in a single integrated unit. They are used for local power distribution in industrial facilities, commercial buildings, and other similar applications.
These are some of the most common types of oil-immersed transformers. Each type has its own specific design and application, but they all rely on the use of oil as a cooling and insulating medium to ensure efficient and reliable operation.
