20V 1000A igbt based plating rectifier Features
Cabinet: Cabinet adopts magnetic cut links, reduce eddy current losses, and
cabinet as a whole spray painting | Structure: Reasonable structure design, isolated the inverter part and ,
rectification part , convenient to disassemble and maintenance |
Radiator: radiator capacity expanded 1.5 times,make sure better cooling
effect | switch control way: adopt full bridge phase shifting soft switch,reduct IGBT loss,save
engergy |
Main transformer: adopts amorphous core,increase transformer efficiency,reduct the
transformer temperature rise,cut the rectifier weight,improve the
power supply stability, reliability | Core & Schottky diode: core capacity expanded 1.5 times schottky diode expands 4 times
|
Board : all control boards did anticorrosion treatment with imported three
defense lacquer | IGBT: IGBT capacity expanded 3 times,make the power supply more reliable |
20V 1000A igbt based plating rectifier picture:
THE DIFFERENCE BETWEEN SCR & IGBT SWITCH RECTIFIER
1, efficiency
SCR: 70%
IGBT:90%
2,Transformer
SCR:Power frequency transformer, large volume about 200kg
IGBT:without Power frequency transformer
3,Energy saving efficiency
SCR: bad
IGBT: energy saving about 15%-30%
4, start/stop with load
SCR: can’t
IGBT: can
5,control circuit
SCR:Complex, request synchronous and difficult to integrate
IGBT:use the simple integrated circuit board, and anti-corrosion
treatment completely closed.
6,constant current accuracy
SCR:＜5%
IGBT:＜1%
7,cooling way
SCR: water/oil/air cooling
IGBT:water/air cooling
8,work frequency
SCR:50HZ
IGBT:20KHZ
9,control way
SCR:Phase shift trigger
IGBT: PWM
10,output DC
SCR:half wave
IGBT:High density DC square wave
11,Disturbance to power grid
SCR: large,Not easy to eliminate
IGBT: small,easy to eliminate
12,size and weight
SCR: large size and heavy
IGBT: small and light weight
13,Allowable fluctuation range of input voltage
SCR: ±10%
IGBT:±15%
20V 1000A igbt based plating 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.
