60V 4000A IGBT oxidation rectifier
oxidation description:
It is well known that certain metals, notably aluminum and
tantalum, as anode in a suitable electrolyte become coated with
a thin oxide film, and then exhibit rectifying properties: the
currents are very small for the alu,minum positively charged with
respect to the solution, while opposite polarity they may be very
large, the process of formating an oxide film is caused by Al ions
flowing from the aluminum through the oxide into the solution under
the influence of the high electric field in the layer and combining
with oxygen ions, the thickness of the oxide film For constallt
applied voltage the current decreases exponentially with time until
a
small current of less than a micoampele per remaines flowing, so
that after several hours remarkable increase of the thickness
cannot be measured,The thickness of the layer is proportional to
the formation voltage and of the order of 10-5 The purpose of this
paper is to discuss the mechanism of the electric conductivity of
the aluminum rectifier.

60V 4000A IGBT oxidation rectifier Installation
| 1, Placing rectifier and keep the body stability; ensure good ventilation. |
| 2, Checking anodizing rectifier out cover if loosing. |
| 3, Connecting shell to ground to prevent static electricity. |
| 4, Conecting the AC input wire |
| 5, Connecting the DC output copper bars |
| 6, Connecting the rectifier remote control box,if local control ,skip this step |
| 7, Turn on air switch, then the fan starts to rotate and the power indicator light. |
| 8, Clockwise rotation adjustment button, voltmeter degree increases, working indicate light lighting. |
| 9, Adjust knob to maximum, then the voltmeter should indicate the rated voltage, current meter indicates the load volume accordingly. |
| 10, Disconnect the air switch, turn off the rectifier |
produce process :
From the beginning of the raw material to the selection, to the assembly, and finally commissioning. We will enforce the standards strictly. Before package, 24V 125A dc single output switching power supply with CE will be check again to ensure that it works normally.
