Capacitor selection for medium frequency induction furnaces
Capacitor selection guide
Capacitor is typical core components of medium and high-frequency induction heating and electric heating equipment. The special working environment requires the capacitor to withstand high frequency, large current and high reactive power density.
1. Typical Application of induction heating
- Induction hardening of gears, shafts and connecting rods
- Steel pipes and steel bars are continuously heated
- Automated induction heat treatment line
2. Features
- High frequency 1-3Khz
- high frequency start-stop
- Power concentration
- The capacitance loss is extremely high, capacitors must be water-cooled type
3. How to select capacitors for induction furnace?
The water-cooled capacitor with forced heat dissipation design make it’s stable under high frequency,high current environment.The below are reference of industrial-grade water-cooled capacitor specially designed for medium-frequency/high-frequency induction heating resonant circuits.
