7. Customer Benefits of Green Power Anodizing Rectifier
uHigh Reliability
Although the investment for the DC power supply is minor compared to the total plant cost, a loss of power results in tremendous loss in production, industrial industry do not allow any compromise on reliability of the rectifier. Protection measures (e.g high voltage absorbing circuit) adopted to protect components in case of power shortage.
Fully digital control system, anti-jamming, strong ability to resist strong magnetic field, high reliability.
Using high precision current sensor as feedback control to improve the reliability of system operation
Using optical fiber transmission thyristor trigger pulse signal, suppress magnetic-field interference and improve the control system of electromagnetic compatibility to ensure the stable operation of the system.
This set of power system components are all use imported or domestic products with high quality, make strict inspection to the device, and fully guarantee the reliability of the equipment.
uPower Saving
Save energy and increase revenue, electrical energy is a costly and valuable resource and one of the major cost factors. Therefore Green Power has spent years tuning its systems to provide utilities with the highest efficiency and the lowest electrical losses.
Our solution is based on design criteria that all result in energy savings:
− Optimized transformer and rectifier design
− Customized selection of semiconductor and power fuse
− Shortest possible transformer-rectifier connection
− Custom design to keep current density in power conductors and DC isolators low
uHigh Output Stability, High Control Accuracy
High stability and high accuracy(default <0.5%) ensure high quality electrowinning products.
TI company's DSP chip, programmable full digital control system, trigger pulse features are consistent.
Using the military level pulse transformer, Pulse asymmetry degree ≤0.1 °, Pulse leading-edge steepness ≤1uS.
Controller is equipped with communication interface, can be communicate with PLC directly,ensure system response time and system processing precision.
uLow Output Ripple
Low ripple(default <5%) ensure high quality electrowinning products.
The optimal transformer adopts 12/18/24/… pulse rectification, through thyristor control angle get lowe ripple with fully conducted condition.
uHigh Power Factor
High power factor reduce reactive power, transformer's capacity and line current.
Thyristor control angle are controlled between 12-25 degrees during system operation, when thyristor control angle is less than 12 degree, the system send tap changer upshift signal; when thyristor control angle is greater than 25 degree, send downshift signal. The signal of upshift and downshift are automatically controlled by rectifier or switched manually, to improve power factor and reduce harmonic content.
uLong lifespan
More than 25 years lifespan, reduce investment.
Reasonable design, high quality parts and materials, excellent craftwork, ensure the high realiability of the Rectifier.
uFriendly HMI
Intelligent and convenient operation and monitor.
Touch screen control, operation and display.
Convenient forming network, analog signal, RS485, communication, convenient remote control.
