70V 1500A IGBT High Frequency Hard Oxidation Rectifier With Air
Cooling System
70V 1500A IGBT high frequency hard oxidation pulse rectifier with
air cooling system
During the oxidation process, the workpiece continuously generates
gas, hindering the continued oxidation, making the oxide film loose
and porous, and the intermittent high and low current conversion
rectifier of the pulse power rectifier works, which is conducive to
the precipitation of gas, easy to form a film, the film thickness
increases, the oxide film It is denser, and its hardness, thickness
and color are greatly improved. At present, the commonly used
oxidation power supply is a DC power supply, and its output has no
pulse, so the output generated is relatively loose, and the
thickness, hardness, and color of the oxide film cannot reach the
effect of pulse oxidation rectifier;
Superior performance of hard oxide pulse rectifier:
1-32 minutes adjustable soft start time, and can be used as a pulse
soft start, especially suitable for hard oxidation process;
1-256 minutes running time is adjustable (independent of soft start
time), automatic shutdown;
Multiple working options: pure pulse, pulse superposition, DC, etc
.;
During the operation, it can display all operating parameters at
any pulse frequency, duty cycle, pulse-based high & peak value, so
that you can fully control what workpiece is in the end;
Under operating conditions, the parameters can be freely modified,
adjusted, and stored at any time. After the power is turned off,
the time is saved for 35 years. The stored parameters will be
automatically run at the next startup;
According to the anodizing characteristics of aluminum and
titanium, the working method is current stabilization and voltage
limiting work to ensure sustainable and efficient oxidation. With
the extended power bath of electrical solutions, the thickness of
the oxide film increases if the output voltage rises to safety In
the set value tree, the voltage stops rising, and crent gradually
decreases, which really protects the workpiece from melting;
Perfect safety guarantee measures, with a variety of intelligent
fault protection, over current, fault phase, phase sequence error,
short circuit;
The transformer coil winding and bus bar are made of high-quality
copper (copper content 99.99%), with good conductivity and high
current efficiency;
The transformer coil adopts double vacuum impregnation process,
which has good insulation and corrosion resistance.
