300KW Welded Equipment For Pipe Mill Duct Making Machine Solid State High Frequency Welder
 
 
Technical Features
Display instrument digitization
The rectifying cabinet panel is equipped with a multi-function digital meter, which has three phase input line voltage, three-phase line current, power factor, reactive power, active power, power, DC voltage, DC current and other parameters, and can be controlled, displayed and recorded through communication far to the upper computer.

Full digital rectifying control board
The new generation of solid state welding machine, using the field programmable logic gate array (FPGA) main control chip, the main frequency up to 100M, 16 bit A/D conversion chip (the original control board using 8 bit A/D conversion chip), the high precision of the data resolution; the cancellation of all the adjustable potentiometers on the board (12 control potentiometers in the original control board), color touch screen control System and parameter setting, debugging and operation are simple and intuitive. All parameters in the rectifier board can be transmitted to the host computer for display and recording through communication. The unique parallel working mode of FPGA ensures that the modules of the program operate at high speed and independently. And because of the hard line logic inside the FPGA chip, there is no problem of running the program, and the stability of the control system is enhanced. The full digital rectifying board adopts the double closed loop PI regulator, the inner ring is the current regulating ring, the outer ring can be set up to two modes of constant power or constant pressure (optional touch screen). It has the characteristics of high control precision, fast adjusting speed, strong flexibility, good interface extensibility and so on. It can achieve real one key control.

 
All digital inverter control board
The new generation of solid state high frequency welder has integrated the advanced control concept of similar products in the world. The field programmable logic gate array (FPGA) is used as the main control chip to realize the advanced control technology such as the fixed angle lock phase control, the upper / lower frequency locking protection and so on, which makes the equipment running more stable and more efficient. The inductor short circuit and open circuit fault protection in welded pipe production is more accurate and effective. At the same time, it has the function of frequency output, and it can transmit and run parameters to PLC display and record remotely.
The new inverter control board uses the pulse shielding technology (PSM) to adjust the power of the inverter, and successfully solves the load matching problem of the welding machine. When the user changes the steel pipe specification, the contact welding / induction welding switch, the impedance matching can be achieved without any changes to the welding machine, and the welding machine can be full power output under any working condition. The welding machine can guarantee the DC voltage to the rated value after 20% power, and the welding machine can guarantee the highest power factor and the minimum harmonic current when the 20%~100% power is rated. It has the advantage that the traditional power regulation mode can not be compared.

 
The high frequency voltmeter and the ammeter touch screen display of the operation console
The welding machine and the operating table are connected by communication, and the resonant frequency of high frequency, active, reactive, power, DC voltage, DC current, armature voltage and armature current are displayed in the touch screen of the operating table.
