The single phase oil-immersed transformer is a cornerstone of modern electrical systems, designed to efficiently change alternating current (AC) voltage levels. This versatile device transfers power seamlessly between circuits without altering the frequency, making it an essential component in both residential and industrial applications. By leveraging advanced engineering principles and robust construction, single phase oil-immersed transformers ensure reliable performance and minimal energy loss.
Operating Principle
1. Magnetic Field Generation: When an alternating current (AC) power supply is applied to the primary coil of a single phase oil-immersed transformer, it induces a dynamic magnetic field. This magnetic field is crucial for the transformer's operation, as it fluctuates in response to the varying current.
2. Voltage Induction: The changing magnetic field passes through the transformer’s core, which is typically made of high-quality silicon steel. This core directs the magnetic flux through the secondary coil, inducing a voltage and generating an electromotive force (EMF) in the secondary coil.
3. Faraday’s Law in Action: According to Faraday’s law of electromagnetic induction, the induced EMF is directly proportional to the rate of change of the magnetic field. This fundamental principle ensures that the transformer can efficiently convert voltage levels based on the primary coil's varying current.
4. Turns Ratio and Voltage Conversion: The voltage in the secondary coil is determined by the transformer’s turns ratio. The ratio of the number of turns in the primary coil to the secondary coil dictates the voltage conversion. By carefully designing this ratio, engineers can achieve precise control over the output voltage.
5. Efficient Voltage Regulation: Ultimately, a single phase oil-immersed transformer converts the input voltage into the desired output voltage, fulfilling its critical functions of voltage regulation and energy conversion. This process ensures that electrical devices receive the appropriate voltage levels for optimal performance.
Product Structure
Core: The core of a single phase oil-immersed transformer is its backbone, typically constructed from high-permeability silicon steel laminations. This design minimizes energy loss and maximizes magnetic flux concentration, enhancing the transformer’s efficiency.
Coils: The transformer features two main coils: the primary (input) coil and the secondary (output) coil. The primary coil, connected to the power source, generates a magnetic field that induces voltage in the secondary coil. Both coils are meticulously wound around the core to ensure efficient magnetic field transfer.
Insulation Materials: High-quality insulation materials are used to protect the coils and core. These materials prevent electrical short circuits and insulation breakdown, ensuring the transformer’s safe and reliable operation.
Cooling System: To maintain optimal performance, single phase oil-immersed transformers are equipped with an advanced cooling system. The oil-immersion design provides superior heat dissipation, preventing the transformer from overheating during prolonged operation.
