Thepower source with intellectual property rights has reached to leading positionamong domestic inverter submerged arc welding power sources, which is designedto replace thyristor controlled DC power source. High power non-parallelinverter technology is applied for compact internal structure, low system complexityand low potential malfunction rate, which prevents unbalance of two invertermodules and problems occuring.
Capability and traits:
1. Largepower weld power source adopts non-parallel IGBT control with high reliability.
2. Ratedduty cycle can reach to 100%. Especially for long time continuous welding.
3. 200ºC insulation, reactorcoils are Class-H insulated by US Dupont Nomex(R) Paper and JapaneseHITACHI-Chemical insulating varnish with high insulation strength, high temperatureresistance and dustproof. main transformer coils are Class-F insulated by Teflonmaterial with high insulation strength, high temperature resistance anddustproof.
4. Maincircuit with AC contactor, featuring no-load current pull-in, fully enclosed structure,high reliability.
5. Maincircuit with two LEM brand current transformers, featuring high temperatureresistance, anti-interference.
6. Theprotection against short circuit of control cable prevents damage to the PCBcaused by internal short of control cable, short between control cable and theworkpiece or the output cable.
7. FeaturingAnti-interference of high frequency, which protects damage caused by highfrequency and voltage.
8. Overheat,overcurrent, undervoltage and lose phase protections can avoid power sourcefrom damage.
9. Multicharacteristics design for submerged arc welding, electroslag welding, manualwelding and etc.
10. DigitalMCU intelligent control. Self-diagnosis for separate alarming.
11. Powersaving, environment protection, 89% conversion efficiency.
12. Highpower factor can affect less to network. The power factor can reach to 0.94.
