Description
Key Features:
- Cooling and Insulation:
- Cooling: The mineral oil in the transformer acts as a coolant, dissipating the heat generated by the transformer through convection. This helps maintain the temperature within safe operating limits, enhancing the transformer’s efficiency and lifespan.
- Insulation: The oil provides excellent electrical insulation, preventing electrical discharge and ensuring safe operation by insulating the high-voltage components from each other and from the transformer tank.
- Construction and Components:
- Core: Made of laminated silicon steel to minimize energy losses due to hysteresis and eddy currents.
- Windings: Constructed from copper or aluminum, wound in a manner that optimizes electrical performance and mechanical strength.
- Tank: A sealed container that houses the core and windings, filled with insulating oil. It may include features like radiators or cooling fins to enhance heat dissipation.
- Voltage Regulation:
- Equipped with tap changers (on-load or off-load) that allow adjustment of the voltage ratio, maintaining stable voltage levels in the power distribution network.
- Performance and Efficiency:
- High efficiency due to low core and copper losses.
- Long operational life with minimal maintenance requirements, attributed to the effective cooling and insulation properties of the oil.
- Applications:
- Widely used in power distribution networks, substations, industrial plants, and utility applications for stepping up or stepping down voltage levels.
