Medium frequency power supply equipment works
Medium frequency power supply equipment is controlled by a PWM circuit output power, made closed-loop control, power detection circuit output capacitance of the intermediate frequency equipment and furnace body series, rather than a parallel method.So much big fierce thought maneuvering improved equipment, correct the mediation of the intermediate frequency equipment cooling time, improved the production safety coefficient.Medium frequency power supply equipment will not bring the net side pollution, electric transformer no fever, no fever, no compensation capacitance of harassment by electric equipment for other things.
Saving electricity power supply transformer capacity: IGW - 300 intermediate frequency: 315 kva power supply transformer can things.Thyristor intermediate frequency 315 kva transformer cannot work, severe fever, and even abandoned.Medium frequency power supply equipment with three phase power after bridge controlled rectifier not by LC filter, get the voltage 500 VDC.Because is not controlled rectifier, rectifier diode always things in maximum conduction Angle, high power factor.Is controlled by a phase locked loop frequency, active tracking furnace change of natural frequency and other parameters, link intermediate frequency equipment things in zero voltage switching condition, consumption is small, safe zone.
Controlled medium frequency power supply equipment as a result of semiconductor components, no Thai huge machine rotating parts, no shock and noise, in place of the ground work, there is no special requirement.Frequency can be about to change as the load parameters and the implementation of the active change completely.
We also produce hot forming elbow machine,cold forming elbow machine,tee machine,hydraulic press,pipe bending machine,pipe expanding machine,beveling machine,sand blasting machine,pipe cutting machine, steel pipe straightening machine ,welded pipe production line and all kinds of molds.
