Which medium frequency power supply is the most cost-effective choice for electric melting furnace?
1. KGPS dual rectifier intermediate frequency power supply
Adopt 12-pulse rectifier circuit-effectively reduce the 5th and 7th harmonics,
Reduce the pollution to the power grid. Without increasing the incoming line voltage,
Double the rectified output voltage-reduce line loss
Convenient to improve equipment power capacity-greatly improve the stability of high-power equipment
On the premise of increasing a small amount of cost, energy consumption can be greatly reduced-the whole machine can save energy by more than 15%
2. KGPS bias type intermediate frequency power supply
Fast, energy-saving and low power consumption. Energy saving 10%-15% compared with traditional equipment
The load voltage is increased to 2400V-2600V. Low load loss
Mature technology, stable and reliable whole machine, low failure rate
Maintenance and repair are simple and convenient, and the maintenance cost is low
The operation is simple and easy to use, and it is no different from ordinary SCR equipment in terms of operation.
3. KGCX series resonance intermediate frequency power supply
The rectifier circuit is always in full conduction state-to achieve constant power operation power
The overall factor is improved-the operation process is always greater than 0.95
Adopt advanced rectifier circuit–3, 5, 7 harmonics meet national standards
Using series resonant circuit-high load voltage, low load loss
The design principle of the whole machine is energy saving and consumption reduction-saving more than 30% of electricity
One power supply can supply power to two furnaces at the same time-to achieve seamless production.
4. IGBT series resonance intermediate frequency power supply
Adopt German original imported IGBT module-low device loss
Years of technical experience accumulation-mature equipment and stable performance
The design principle of the whole machine is energy saving and consumption reduction-saving more than 30% of electricity
Operate with high rectification coefficient and high power factor-high efficiency of the whole machine
Adopt PLC intelligent control system-complete self-protection function of the whole machine
The output voltage of the load circuit is high-the load loss is only one-fourth of the ordinary electric furnace
