New Generation IGBT Intermediate Frequency Power Supply
By adopting advanced digital control technology, the control accuracy is precise to every kilowatt.The stable rectifier and inverter group ensures the stable output of full power of the power supply at all times, and also has excellent performance in safety and energy conservation.
1.High Power
Compared with traditional IGBT power supplies, we adopt modular and integrated design to solve the problem of no-large power and poor stability of IGBT power supplies in the industry. Our single IGBT power supply can have 50-12000 kw power.
2.Full Protection
Equipped with a door lock linkage system and capactive pressure switch,IGBT bridge short circuit switch,etc.There is a fuse in front of the frequency conversion group for easy isolation of faulty frequency conversion groups.
3.Easy to maintain
Each pipe fitting adopts PISCO connection for easy maintenance and inspection. Each water circuit has water temperature protection connected to the control system through an inspection instrument.
4.Energy Economic
Fast switching frequency, low commutation loss, and stable frequency.Multi pulse rectification, without the need for harmonic filters and DIDT.Full power output at all times, short melting time, and high power factor.

1.Quintuple Leakage Protection
Perfect combination of injection type leakage protection, differential leakage protection, secondary electrode leakage protechtion, optical-fiber detection leakage protection, and cooling system linkage protection.
2.Patented Coil Technology
Designed according to the actual usage conditions of the customer, the optimal number of turns, turn spacing,coil height and other patameters are calculated through computers simulation software to achieve the highest electromagnetic conversion efficiency.
3.Fully Enclosed Type Furnace Design
Effectively avoiding arc striking between loops caused by dust pollution, secondary shielding to the coil's magnetic field, and the magnetic radiation generated by the equipment is equivalent to 10% of competitive products, far below the national standard.

What is he differences between closed shell and open shell furnace?
Eclosed type furnace forms a solid structure, which can better bear strength and lifespan.Also, it can screen the outgoing magnetic flux, reduce flux leakage.Importantly,closed shell is useful for dust/dirt isolation, then decrease the risks of electric arc or leakage.Besides,about 30% down in noise to the open type leakage.
However, the open type furnace , despite of it is convenient to repair,mounts of shortcomings comes.Firstly, poor strength,will go distorted after long term use, working life of induction coil and lining will also be affected.Secondly, dust/dirt bearing metal elemant will be likely absorbed to the induction coil surface, increasing risk of electric arc. Third, electric magnetic fulx will leak between the magnetic yoke and harm the operators.Finally,molten splash in more likely to land on the hose, cable and induction coil surface,jeopardising the system.
