IPM
IPM technology development: Ningbo Haitian Electric Furnace and Huanhu Electric Furnace (Dai Guangzu's team) launched IGBT power supply in 2009, which further improved the energy saving effect, saving 6% energy than thyristor power supply. In 2019, it launched a new dual DSP controlled IPM power supply. It is the first to use no reactor, which saves energy by 10%-20% compared with the previous thyristor power supply. The output power of IPM covers 5KW-6300KW. This series of power supplies has been successfully applied to 10KG-12T intermediate frequency electric furnaces. Haitian IPM intermediate frequency smelting power supply has the advantages of high-power overall layout, unique module design, and unique power control method. With the successful launch of Haitian IPM module high-power power supply, other domestic manufacturers of thyristor intermediate frequency power supply have imitated them. Within five years, IPM power supply will be All replace the thyristor power supply.
Select HaitianIPMMF PowerTop 14 Reasons span>
1. The power supply of Haitian electric furnace IPM module is more stable and reliable than traditional thyristor, and the replacement of accessories is more convenient and easy to operate than thyristor power supply. The price of accessories is almost the same as that of thyristor. , the key is that the service life of the IPM power supply is several times higher than that of the thyristor power supply.
2. Overcoming the shortcomings of previous IGBT's high requirements for the surrounding environment, Haitian electric furnace IPM can be used in any environment without being easily damaged.
3. Haitian IPM intermediate frequency power supply has a "self-diagnosis" function, which displays the cause of the fault and the location of the fault, avoiding the trouble of blindly looking for faults by maintenance personnel in the past. And maintenance personnel can remote control monitoring.
4. Haitian IPM intermediate frequency power supply adopts dual DSP (US) control, fully digital fuzzy control, eliminating the need for reactors, and more energy-saving than other IGBT power supplies.
5. Haitian IPM intermediate frequency melting system adopts MATLAB software simulation design to ensure that the whole set of equipment has the highest efficiency, the best reliability and stability.
6. Haitian IPM intermediate frequency melting furnace saves electricity by 10-20% compared with traditional thyristor power supply, and the melting time of each furnace can be reduced by 10-20 minutes, saving electricity within one year. The equipment investment can be recovered.
7. Haitian IPM intermediate frequency melting electric furnace is fully guaranteed for 18 months free of charge (the leakage of the furnace is not guaranteed)
8. Haitian IPM adopts building block design, which solves the problem that the power of IGBT power supply is not big in the past. The power can cover 10KW-10000KW and higher, and the power can be expanded infinitely, breaking through the previous IGBT power increase. On the unstable technical bottleneck.
9. Haitian IPM disassembly module does not affect the operation of the whole machine. N+1 redundancy theoretical design, the reliability of each redundant board of the equipment is improved by an order of magnitude, each module unit operates independently, and the current is intelligently distributed according to the output power.
10. Haitian IPM multi-layer busbar design, the multi-layer busbar is designed through MATLAB software simulation, which cleverly solves the problem of busbar heat dissipation, solves the influence of distributed inductance, and solves the influence of heat dissipation and peak voltage on IPM , make the IPM more reliable and stable and not easy to damage.
11. Haitian IPM adopts ZVS and ZIS control technology. ZPM adopts zero-voltage and zero-current turn-off and turn-on during phase commutation, which reduces the switching loss of IPM, improves the working efficiency of the equipment, and saves more energy. .
12. The reasonable layout of Haitian IPM not only improves equipment efficiency, but also makes maintenance more convenient. ; max-width: 100%; box-sizing: border-box !important; overflow-wrap: break-word !important; font-size: 15px; letter-spacing: 0.5px; background-color: rgb(255, 255 , 255);">toThe complicated process of replacing the IGBT module greatly reduces the 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 multi-rectification and multi-inversion. Damage to any group of finishing inverters will not affect the operation of the whole machine in the case of one dragging too much.
