Brief introduction and advantages of 300KW Solid State High Frequency Compact Pipe Welder

Dear customers, thank you for choosing our equipment. We will do our utmost to cooperate with you in good faith, to make our equipment and after-sales service work well, to make the best performance and create the maximum benefit for you.

To avoid unnecessary losses, now we would like to describe more details about the requirements for the installation and use of the equipment and the problems to be noted.

This equipment is a high-tech machine, and was carefully developed by our company's engineers on the basis of our company's common solid-state high frequency. Also this welder used in the field of straight seam welded pipe (induction welding, contact welding), hardening, brazing and so on. Compared with the original and normal solid-state high-frequency equipment, it has the following advantages:

1.Small size and light weight: The rectification part and the inverter part are installed in one cabinet. The installation is compact and reasonable. The overall volume is 50% smaller than the ordinary high-frequency equipment of the same specification, and the weight is reduced by more than 30%.

2. Energy saving and water saving: without the step-down transformer, the interconnection cables are obviously shortened, and the power factor is as high as 0.95, thus reducing many line or cables losses. Tests have shown that this equipment can save more than 5% of electricity than ordinary solid-state high-frequency equipment of the same specification.

3. The rectifier part adopts the diode uncontrollable rectifier bridge, so there is no need to recognize the phase, and the three-phase power supply ABC is connected freely, which is convenient for testing and maintenance.

Main circuit description

The main circuit of this device is basically the same as the thyristor intermediate frequency power supply (see attached figure). The three-phase 380V AC enters the three-phase full-control bridge and becomes a pulsating DC. The smoothing reactor and the filtering device convert this DC filter into a straight DC, and then become a high-frequency AC supply tank through the single-phase inverter bridge. The circuit (the capacitor and the inductor form a tank) acts as an oscillating power source.
