The operation mode of the elbow machine wearing the medium frequency power supply

Pipe fitting equipment manufacturers mainly produce elbow machine, tee machine, pipe expanding machine, press, groove machine, aligning machine, straight seam welded pipe production line, mold and other products. The above pipe fitting equipment is mainly equipped with the intermediate frequency power system is described as follows:

The output power of the IF power supply device is controlled by the PWM circuit, and the closed-loop control is formed by the power detection circuit. The output capacitance of the IF device and the furnace form a series situation, rather than a parallel method. This greatly improved the operation of the equipment, correctly adjusted the cooling time of the intermediate frequency equipment, and improved the production stability coefficient. Intermediate frequency power supply equipment will not bring network side pollution, electric transformer does not heat, electric compensation capacitor does not heat, do not disturb other equipment.

Power-saving power supply transformer capacity :IGW-300 medium frequency :315KVA power supply transformer can be things. And thyristor medium frequency 315KVA transformer can not work, severe heating, and even abandoned. Intermediate frequency power supply equipment with three-phase power supply through the bridge uncontrolled rectification after LC filtering, 500VDC voltage. Since the rectifier is not controlled, the rectifier diode always operates at a large on-off Angle, which determines the high power factor. The PLL controls the frequency of the event, actively tracks the change of the natural frequency of the furnace and other parameters, connects the IF equipment to the zero voltage switching state, the consumption is small, the stable area is large.

Controllable intermediate frequency power supply equipment is composed of semiconductor components, and there is no Thai huge machine rotating part, no shock and noise, and there is no special requirement on the ground at the time of placement. The frequency is fully active and can be changed roughly with the parameters of the load.
