Function Structure
The series IGBT medium/superaudio frequency induction heating power supply adopts AC-DC-AC variable frequency power supply structure. The rectifier of the power supply adopts 3-phase thyristor rectifying. 12-pulse rectifier can be adopted for large power equipment (above 1000kW) to decrease grid side harmonic current. The inverter adopts high voltage large power IGBT module to form inverter power unit, to realize large power output through the superposition of inverter power unit. The inverter realizes impedance matching and electric isolation through matching transformer. The resonant tank circuit adopts serial resonance, which needs independent design for different load heating.
The whole unit of equipment is composed of serial induction heating power supply, resonant tank circuit, circulation soft water cooling system, console (optional), automatic control system (optional).
Technical Features
Ø Perfect structure design
1.Integration design of switchgear rectifying cabinet and inverter output cabinet, with compact structure and small size.
2.Power combination of the inverter bridge is accomplished by the way of power unit superposition, which is convenient for installation and repair. Each IGBT power unit is designed to be 100kW or 200kW. Inverter output adopts matching transformer to realize electric isolation of power supply and load with high security and reliability of power supply.
3.With high voltage and small current of inductor, the whole heating efficiency of power supply is higher than parallel power supply.
1. Resonant tank circuit mode is an independent design as per user’s actual requirement with convenient and flexible site layout.
2. High standard electromagnetism compatibility design, electromagnetism radiation meets national standard. Closed cabinet design, meeting rigor environmental requirements on site.
Ø Full digital control system
1. 3-phase rectifier adopts high cost performance MCU controlling to realize precise synchronism trigger with high control precision and small grid-side non characteristic harmonic.
2. Resonant inverter adopts CPLD to form full-digital control system that is characterized by their automatic constant angle, high phase-lock precise and wide scope of phase-lock.
3. Adopt inverter side PSM power adjustment technology with strong load adaptability and easy impedance matching. The grid side power coefficient≥0.92 and harmonic content is the relatively lowest.
4. The power supply has perfect protection function with reliable working and low failure rate.
Ø HMI and fault diagnosis system (optional)
1.Adopt PLC and touch screen to form perfect HMI system.
2. Realize integrated automatic control of power supply system.
3. Fault display and diagnosis system.

- Q:Heat treatment equipment (industrial furnace), which products generally contain what kind of, which industries need to use heat treatment industrial furnace equipment.
- The general metal die casting plant and the metal smelting plant need process melting and dissolving furnace, usually there are reverberatory furnace, cupola, rotary furnace, etc. I do the melting furnace of aluminium alloy.
- Q:Selection of heat preservation material for industrial furnace
- Ceramic fiber blanket can be used.Ceramic fiber blanket color white, regular size, set fire, heat insulation, insulation in one. Free from any binding agent.
- Q:Why does the burner of industrial furnace burn occasionally?
- The general process for burner ignition, blowing furnace, electric spark ignition, solenoid valve, open the gas in case of delayed spark ignition, detection device detects the flame, the controller accepts signal so that the solenoid valve open, gas continuous normal combustion. However, if the ignition fails or the burner fires, the detector cannot detect the flame, which causes the solenoid valve to close and the burner flameout.
- Q:What is an industrial furnace pit?
- The creation and development of industrial kilns play an important role in the progress of mankind. Chinese appeared more perfect in the Shang Dynasty copper smelting furnace, furnace temperature is up to 1200 DEG C, up to 0.8 meters in diameter kiln stove.
- Q:What is the difference between industrial furnace masonry and ordinary masonry?
- Of course, the difference is like the difference between a hog cap and a 100 story building. See the industrial furnace manual.
- Q:How many kinds of industrial electric furnaces are there?
- Industrial furnace according to the heating mode is divided into two categories: one is the fuel furnace, combustion heat with solid, liquid or gaseous fuel in the furnace for heating the workpiece; the second is in the furnace, the furnace converts electrical energy to heat the heat.
- Q:Brief introduction to repair of industrial furnace
- Although the number of industrial furnaces in general machinery plants is not large, the number of large repairs per year accounts for 16%-20% of the total number of repairs for all equipment, and the large repair costs account for about 18%-25% of the total repair cost of all equipment.
- Q:What is industrial furnace masonry?
- Plane construction must level, slope construction must find slope,refractory bricks must be selected and processed according to masonry requirements.
- Q:What is the difference between industrial furnaces and boilers?
- Industrial kilns and industrial furnaces are collectively referred to as industrial furnaces. Industrial furnaces mainly refer to devices that heat materials by combustion reactions.
- Q:How to use industrial furnace equipment?
- If it is water cooling furnace door, but also to ensure the smooth flow of pipes, winter pipes are not frozen. When the boiler is in a limited position, the interlocking device for cutting off the power supply shall be provided when the furnace is in and out, and the number of broken wires in the pitch of the steel wire shall not exceed 10%, and the counterweight of the furnace door shall be reliably hung.
