600KW High Frequency Pipe Welding Machine

Rectifier cabinet of 600kw high frequency pipe welding machine

1.The solid-state High frequency pipe welding machine rectifier cabinet adopts integrated design which connect switch gear cabinet and rectifier parts.

2.The rectifier adopts a three-phase full bridge SCR phase control circuit, and through previous stage passive filter can ensure that the equipment has higher power factor and smaller harmonic content.

3.The control circuit adopts a DC voltage based on a micro-controller, and DC current double closed-loop control and ensures that the DC voltage continuous smooth adjustment from 0 to rated value.

4.Equipped with comprehensive protection functions to ensure the safety of equipment Stable operation.

Inverter output cabinet of 600kw high frequency pipe welding machine

a. The inverter section is composed of MOSFET single-phase inverter bridges and connected in parallel, single bridge power design is 125kW/60kW, inverter bridge adopts a modular approach to complete power stacking, with each block bridge deck is designed as a drawer type structure composed of slides structure, convenient for installation and maintenance.

b. Using matching transformers to complete power synthesis, using transformers secondary resonance and no welding transformer output.

c. The inverter control circuit adopts fixed angle control and has the following functions: well anti lock and over-current/over-voltage protection functions ensure efficient and reliable operation of inverters.

d. Adopting a sealed chassis, water-cooled and externally air-conditioner cooling method.
