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.
[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.
[Closed loop technology of speed power]
The new generation of solid-state high frequency welding machine is designed with the most advanced pulse shielding technology (PSM control technology). It can guarantee the best load matching state of the solid high frequency welding machine with the highest welding efficiency, the highest power factor and the lowest net side harmonic current. The customer only needs to input the parameters of production specifications and wall thickness through the touch screen. The welding machine can automatically calculate the output power of the high frequency welding machine according to the speed of the car, reduce the waste of the steel pipe, improve the yield of the steel tube and the efficiency of the operator.
[Ethernet networking technology]
The distributed production line is constructed by Ethernet communication between rectifier cabinet and operation table. Compared with hard wire control, it has advantages of on-site wiring, simple and convenient, reducing customer costs and maintenance costs. Compared with MODBUS communication and DP communication, it has faster speed and stronger anti-interference ability. Data acquisition and recording can be carried out.
[Cloud control technology (optional)]
The cloud service module is selected, all data can be monitored and recorded remotely, and the production line can be controlled remotely. It is convenient for customers to conduct data analysis, product quality control, production scheduling and automatic control of higher requirements.

Process structure
[The new bridge inverter technology design]
The new technology inverter bridge plate is made of the 12mm purple copper plate surface plating technology and the oval inner channel cooling, the surface of the water cooled plate is more smooth and the cooling effect is better. The temperature of the power element is better than the original inverter bridge under the same environment (using the tin plating process of the 5mm thick purple copper plate and the surface welding copper tube cooling mode) Low 3~5 degrees Celsius improves the safety of power devices.
The new bridge power inverter
[Bridge high frequency capacitor using PCB board installation process]
The high frequency absorption capacitance of the inverter bridge is more reasonable, the assembly and maintenance is more convenient, the quantity of the capacitor is 3 times of the original bridge plate, the absorption effect is better, and the safe operation of the power device is ensured.
[New MOS drive board]
The MOS negative pressure detection function, the MOS tube pulse detection function, and the positive voltage detection function of the power supply can be increased, which can effectively prevent the equipment from disease and reduce the two damage caused by the incomplete maintenance.
[The protection of the matching transformer and the capacitor of the groove]
Matching transformer and channel capacitance to install temperature protection switch to prevent overheating damage caused by blockage of water pipe.
[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.
