The IPM module power supply of Haitian electric furnace is more stable and reliable than traditional thyristor power supply, and the replacement of accessories is more convenient and easy to operate. The price of accessories is almost the same as that of thyristor power supply. The key is that the service life of IPM power supply is several times longer than that of thyristor power supply. 2. Overcoming the high environmental requirements of IGBT in the past, the Haitian electric furnace IPM can be used in any environment without being easily damaged. 3. The Haitian IPM medium frequency power supply has a "self diagnosis" function, which displays the cause and location of the fault, avoiding the trouble of previous maintenance personnel blindly finding faults. And maintenance personnel can remotely control monitoring. 4. Haitian IPM medium frequency power supply adopts dual DSP (USA) control with fully digital fuzzy control, which eliminates the need for reactors and is more energy-efficient than IGBT power supplies from other manufacturers. 5. The Haitian IPM intermediate frequency smelting system is all designed using MATLAB software simulation to ensure that the entire equipment has the highest efficiency, reliability, and stability. 6. The Haitian IPM medium frequency melting furnace saves 10-20% of electricity compared to traditional thyristor power sources, and the melting time of each furnace can be reduced by 10-20 minutes. By saving electricity costs within a year, the equipment investment can be recovered. 7. The Haitian IPM medium frequency melting electric furnace is fully free of charge for 18 months (no warranty for furnace leakage). 8. The Haitian IPM adopts a modular design, which solves the problem of small IGBT power supply in the past. The power can cover 10KW-10000KW and higher, and the power can be infinitely expanded, breaking through the technical bottleneck of unstable IGBT power when it is increased in the past. 9. The disassembly of the Haitian IPM module does not affect the overall operation of the machine. The N+1 redundancy theory design increases reliability by an order of magnitude for each redundant board in the equipment. Each module operates independently and intelligently distributes current according to output power. Any module fault will automatically exit, and the remaining units will automatically redistribute current. 10. Haitian IPM multi-layer stacked busbar design, the multi-layer busbar is designed through MATLAB software simulation, cleverly solving the heat dissipation problem of the busbar, solving the influence of distributed inductance, and solving the influence of heat dissipation and peak voltage on IPM, making IPM more reliable, stable, and not easily damaged. 11. Haitian IPM adopts ZVS and ZIS control technology, and ZPM uses zero voltage and zero current to turn off and on during commutation, reducing IPM switching losses, improving equipment efficiency, and making it more energy-efficient. 12. The reasonable layout of Haitian IPM not only improves equipment efficiency, but also makes maintenance more convenient, solves the complex process of replacing IGBT modules, and greatly reduces maintenance time. 13. Haitian IPM adopts a new type of signal sampling, which solves the problem of high-power IPM control signal sampling. 14. Haitian IPM adopts multiple rectifiers and inverters. Damaging any set of sorting inverters in a one to many situation does not affect the overall operation of the machine.

1. Furnace weighing system;

2. The backward tilting device of the furnace body facilitates workers to scrape slag;

3. The magnetic yoke adopts a W-shaped design, covering a coil area of more than 65%, to minimize magnetic leakage. Select high-quality silicon steel sheets and adopt a non water magnetic yoke method, which is more energy-efficient.

4. The double support cyclone dust removal cover is more stable when flipping and can stay at any angle.

5. The water-cooled coil and the effective coil are made of copper tubes that are wound together in a flat manner. There is an arc-shaped insulation gasket between the turns, which ensures even coil spacing and facilitates the discharge of moisture. The coil is wrapped with insulation and high-temperature resistant material to prevent high-temperature metal dust from splashing and damaging the induction coil. Copper nails implanted in the coil are combined with injection type leakage furnace alarm.

6. Each return water has temperature protection and water pressure protection
