Ang transpormer ay mahalaga sa pagpapatakbo ng intermediate frequency (KUNG) mga hurno, with its stability and reliability directly impacting the system’s efficiency and heating quality. Using electromagnetic induction, the transformer enables efficient voltage and current conversion to meet the specific demands of the IF heating process. It primarily consists of a primary coil, a secondary coil, and an iron core (magnetic core).
When alternating current flows through the primary coil, it generates alternating magnetic flux in the iron core, inducing electromotive force in the secondary coil, which facilitates voltage transformation.
The key functions of the transformer include voltage transformation, current regulation, impedance matching, electrical isolation, voltage stabilization, and power transmission.
Our IF furnace transformers include:
- Power Transformer: Converts high-voltage AC (e.g., 220V or 380V) into low-voltage AC (e.g., 18V) to meet the specific voltage requirements of components like the IF control board.
- Intermediate Frequency Transformer: Converts higher IF voltages (typically above 18V, depending on requirements) into lower voltages (such as 100V or 20V). This ensures circuit protection functions like voltage limiting and overvoltage control in the IF board.
- Kasalukuyang Tagapagbagong-anyo: A specialized transformer that scales larger current signals down to manageable levels (typically 5A or 1A), making them easier to measure, protect, and control. In IF systems, current transformers are commonly used for current limiting and overcurrent protection.
When choosing a transformer for an IF furnace, factors such as type, capacity, and transformation ratio should be carefully selected based on specific application needs. It is also essential to consider insulation, cooling, and protection features to ensure safe and reliable operation.
Regular inspections and maintenance are key to prolonging the life and stability of IF furnace transformers. Maintenance tasks include checking insulation resistance, measuring winding DC resistance, inspecting oil levels and quality, and cleaning the cooling system.
