The new generation IGBT induction furnace power supply is a constant power output power supply that can achieve full power output with a small amount of material added, and always remains unchanged, greatly improving melting efficiency and reducing power consumption. The inverter device used is a new type of IGBT module (insulated gate bipolar transistor, which has the advantages of controllable turn off and fast response), mainly used for melting ordinary carbon steel, alloy steel, cast steel, non-ferrous metals, especially for melting pressed blocks, iron filings (powder), copper, aluminum, and stainless steel, with more obvious advantages; It has significant advantages such as fast melting speed, low power consumption, and low harmonic pollution. The new generation of energy-saving IGBT induction furnace power supply has been fully upgraded on the original basis, with easy maintenance (low maintenance cost), environmental protection, energy saving, stability, and high efficiency. It has great innovation and improvement in advanced aspects!
1. Low module damage rate: The circuit board and assembly structure of the IGBT induction furnace power supply have been greatly optimized, and the IGBT module is a high-power device that can self turn off, with fast turn off speed and rapid protection. Therefore, the equipment protection is reliable, and IGBT modules are not easily damaged by furnace penetration, grounding, grounding, and water-cooled cable burnout, with a much lower damage rate than the frequency of thyristors.
2. Easy to maintain: Improved on the original basis, with fewer filtering capacitors and IGBT single module assembly, it is more convenient to disassemble and assemble after damage, and the cost is lower;
3. Energy saving: It saves the air core inductance (with high losses) that prevents the current rise rate in the series connection of thyristors, shortens the automatic shutdown time, and significantly improves the power factor to above 0.98. The efficiency of IGBT induction furnace power supply is increased by more than 20% compared to ordinary parallel electric furnaces, and by more than 10% compared to thyristor series electric furnaces.
