How to choose an induction heating furnace reactor‍?

1. The reactor of induction heating furnace is composed of copper tube coil, silicon steel sheet, insulating plate and bracket. Used in 220-2000V power system, in series with parallel capacitor bank to limit closing inrush current and suppress high-order harmonics, thereby protecting capacitor bank, improving grid voltage quality and safe operation of power system

2. Induction heating furnace reactor standard:

The design and manufacture of induction heating furnace reactor should meet the requirements of IEC60076-6 “Reactor”, GB10229 “Reactor”, JB5346 “Series Reactor” and other standards

3. Induction heating furnace reactor ‍Manufacturing process:

The induction heating furnace reactor adopts the silicon steel sheet stacked according to a certain shape and thickness in the reactor coil to ensure that the millihenry value of the reactor is within the design range; the copper tube of the induction heating furnace reactor coil adopts rectangular oxygen-free electrolytic copper copper Tube winding, each turn of the copper tube of the reactor coil is treated with four layers of high-voltage resistant insulation, such as dipping, polyimide film, mica tape, and glass fiber tape, so there will be no ignition and discharge; induction heating furnace reactor silicon steel sheet Stacked neatly, the internal perforation is firmly fixed, and the operation is silent.

4. Insulation of induction heating furnace reactor:

The induction heating furnace reactor is made of high-performance composite insulation materials above F grade to ensure that the induction heating furnace reactor remains reliable under severe working conditions. Class H impregnating paint, vacuum impregnating paint, to ensure the safe and low noise operation of the reactor at high temperature. High-quality low-loss cold-rolled silicon steel sheet, small magnetic flux leakage, no change in inductance, and good linearity. The reactors with larger current are designed with no skeleton and foil winding structure, with low temperature rise and beautiful appearance. Strong anti-electromagnetic force capability and short-time overload capability.

5. Model of induction heating furnace reactor:
