Three Phase Oil Cooled Isolation Transformer

A Three Phase Oil Cooled Isolation Transformer is a heavy-duty electrical device designed to provide electrical isolation between the primary and secondary circuits in three-phase power systems. The oil cooling mechanism ensures efficient heat dissipation, making it ideal for environments with high power demands and continuous operation. Here’s an in-depth look at this type of transformer:

Key Features and Components:

  1. Primary and Secondary Windings:
    • Function: The primary winding receives the input voltage, while the secondary winding delivers the output voltage.
    • Benefit: Electrical isolation between the windings ensures no direct electrical connection exists between the input and output, providing safety and protection.
  2. Core Material:
    • Function: Usually made of laminated silicon steel, the core helps to efficiently transfer the magnetic flux between the windings.
    • Benefit: Enhances the transformer’s efficiency by reducing energy losses.
  3. Insulation:
    • Function: High-quality insulation materials are used between windings to ensure electrical isolation.
    • Benefit: Prevents electrical leakage and enhances safety.
  4. Shielding:
    • Function: Electrostatic shielding is sometimes used between windings to reduce noise and interference.
    • Benefit: Improves the quality of the output by minimizing electrical noise.
  5. Oil Cooling System:
    • Function: Uses oil as a cooling medium to dissipate heat generated by the transformer.
    • Benefit: Provides efficient cooling, making it suitable for high-capacity and continuous operations.
  6. Enclosure:
    • Function: Provides physical protection to the transformer components.
    • Benefit: Protects the transformer from environmental factors and mechanical damage.
