Automatic Three - Phase Steel Bar Making Machine Harmonic IGBT Induction

IGBT Induction heating power supply feature:

• Main elements are Germany SIEMENS 400A/1200V big power IGBT consist parallel circle,have a good capability of frequency automatic tracking.
• Voltage/Current double closed circuit control, this mode has constant voltage operation feature, it means the voltage of inductors will not be influenced by Inlet voltage/Load resistor, etc. Constant voltage make the load heating most stable.
• Adopt the most advanced control technology in the world. By a intelligent programming device CPLD, make IGBT induction heating power supply has the function of Fixed-angle&Phase locking/Frequency automatic tracking, etc. This design can improve the stability and efficiency. Because the machine has protect function of Over-frequency or Low-frequency unlock, it can accurately protect wire heating inductors from short circuit and open circuit fault.
• Inverter circuit has function of Fixing angle/ Frequency tracking and control. When the operation condition is changing, the phase angle of inverter will not change, it has wide frequency suitable range.
• Frequency sweep method: High accuracy of phase locking frequency, small attack. Start success ratio is 100%. Power regulating range: 10%~100%.
• IGBT Induction heating device has wide application in heating treatment like Metal melting/Welding/Quenching, etc.
• Working box(see following picture) is with completely closed structure. Inductor and working box are with completely closed structure.
• Quenching furnace and Tempering furnace has active temperature holding device.
• Main power control cabinet improve the sealing degree, inside water cooling machine.
• Air exhaust outlet makes it convenient to collect the smoke and dust.
