DVR dynamic voltage restorer for 3D laser welding machine
3D laser welding machine also called CNC laser welding machine. It mainly uses computer programming to complete automatic or semi-automatic spot welding,butt welding, stitch welding, sealing welding, and complete welding of complex plane lines, arcs and arbitrary trajectories.
Laser welding machines have very high requirements on the input power grid.For example, the input power grid is unstable, voltage drops, and flashes,which will greatly shorten the service life of the welding equipment. The DVR dynamic voltage restorer produced by Nooyi adopts the AC-DC-AC inverter mode,the output power is pure, the dynamic response and stabilization speed are fast, the input voltage fluctuation and stabilization speed is 2ms, and the input and output are fully isolated, free from the harmonic interference of theinput grid , with over-voltage, under-voltage, over-temperature automaticprotection functions and other functions, is an ideal configuration for laser welding machines.
The DVR dynamic voltage restorer mainly solves the power quality problemsof the power grid: large harmonic distortion, voltage flicker, voltage swelland dip, and three-phase voltage unbalance.
