Description 

A medium-frequency furnace transformer is a specialized power conversion device designed to supply stable medium-frequency (typically 100Hz–10kHz) power to medium-frequency induction furnaces. It converts grid-frequency AC power (50Hz/60Hz) into medium-frequency electricity, matching the operating requirements of induction heating systems. Widely used in metal smelting, casting, and heat treatment industries, it acts as the core energy transmission component, ensuring efficient energy transfer from the grid to the furnace to support rapid heating and melting of metals.

Features 

• High Conversion Efficiency: Adopts optimized winding and core designs to minimize energy loss during frequency conversion, ensuring over 95% efficiency in most cases, directly reducing overall power consumption in smelting processes.

• Strong Load Adaptability: Capable of withstanding sudden load changes during metal melting (e.g., from cold charge to molten state), with excellent short-term overload capacity to avoid shutdowns caused by load fluctuations.

• Compact Structure: Integrates with the furnace’s induction system, featuring a space-saving design that reduces line losses between the transformer and the furnace, suitable for tight industrial workshop layouts.

• Enhanced Insulation and Cooling: Uses high-temperature-resistant insulation materials to withstand medium-frequency electrical stress, paired with efficient cooling (air-cooled or oil-immersed) to maintain stable operating temperatures under continuous high-power operation.

• Low Harmonic Distortion: Equipped with harmonic suppression components (e.g., reactors) to reduce harmonic interference to the grid, complying with industrial power quality standards and protecting other connected equipment.
