The Vegetable Oil Green Transformer, also known as a natural ester-filled transformer, is an environmentally friendly power transformer that uses vegetable oil as an insulating and cooling medium instead of traditional mineral oil. This type of transformer is designed to reduce the environmental impact of transformer operation, improve safety, and enhance sustainability.
Vegetable oil-immersed transformers are a type of transformer that uses vegetable oil as both the insulating and cooling medium. They employ materials compatible with vegetable oil, such as specially treated paper and laminated boards, to enhance insulation performance. The insulation structure of the windings and core is optimized to ensure stable operation under high voltage.
These transformers are designed with efficient cooling channels to ensure that the vegetable oil can flow adequately and dissipate heat. They are also equipped with cooling devices such as radiators or fans to further improve cooling efficiency.
The tank of a vegetable oil-immersed transformer is highly sealed to prevent vegetable oil leakage and the ingress of external contaminants. Sufficient expansion space is reserved to accommodate volume changes in the oil due to temperature fluctuations.
The transformer uses biodegradable materials to reduce environmental impact and employs vegetable oil with a high flash point, along with fire isolation measures, to lower the risk of fire. It is also equipped with overload, short-circuit, and temperature protection devices to ensure operational safety.
