    Electric furnace technical information
        

    Comparison of advantages and disadvantages of induction furnace series resonant power supply and parallel resonant power supply:

    project name

    Series induction furnace

    Parallel induction furnace

    Power factor

     

    High power factor:. −0 95, because the series rectifier intermediate frequency furnace of all SCR are in the fully open state

    Low power factor:+0 .92, because the rectifier and intermediate frequency furnace with all SCR are in a semi-open state (according to the national grid requirements need to add extra compensation)

     

    Output voltage waveform

    Rectangular wave

     

    Sine wave

     

    Output current waveform

     

    Sine wave

    Rectangular wave

     

    Induction coil fundamental voltage

     

    Q〜 inverter output voltage

     

    Inverter output voltage

     

    Induction coil fundamental current

    Inverter output current

     

    Q〜 inverter output current

     

    DC filter

     

    Large capacitance

     

    Large reactance

     

    harmonic

    Low harmonics, low pollution to the grid

    High harmonics, large pollution to the power grid

    effectiveness

    High efficiency can be 10%-20% higher than parallel power supply

    Low efficiency because of low power factor and large harmonic pollution

    start up

     

    Startup success rate is 100%

    Because the series resonant power supply is frequency modulated, the power is adjusted by adjusting the frequency of the inverter, so the starting rate is high. 
     

     

    Start success rate<100%

    It is difficult to start the device under heavy load conditions.

     

    use

     

    Easy to use

    Series resonant power supply can realize one-to-one, one-to-two, one-to-three, and other working modes

     

    Inconvenient to use

    The parallel resonant power supply can only achieve one-to-one operation mode.

     

    protection

     

    Complete protection

    Overcurrent protection, overvoltage protection, phase loss protection, high water temperature protection, low water temperature protection, high water pressure, low water pressure, etc.

     

     

    Complete protection

    Overcurrent protection, overvoltage protection, phase loss protection, high water temperature protection, low water temperature protection, high water pressure, low water pressure, etc.

     

    Reliability

     

    High reliability

    Proven reliability exceeds parallel resonant power supply in field use

     

    High reliability

    The technology is more mature than the series resonant power supply. 
     

    Equipment cost

     

    High equipment cost

    Because the tank current passes through the thyristor filter, it uses capacitive filtering.

     

    Low equipment cost

     

    Energy saving

     

    10% to 20% energy saving compared to parallel power supply

     

    Relative series is not energy efficient.
