| 1. |
Voltage regulating with high frequency adopts modular phase-locked digital pulse trigger |
| |
circuit.Unbalance degree of three-phase is lower than 0.5%. |
| 2. |
Main circuit adopts thyristor modular. Water doesn't go through it It has small volume |
| |
and high reliability. |
| 3. |
Electric supply of filament adopts constant voltage device,which has high voltage |
| |
stabilizing accuracy, long life and distinct energy-saving efficiency. |
| 4. |
Filament rid adopts air-cooling. Blocking adopts large capacity and high voltage |
| |
resistance mica condenser. |
| 5. |
Rectifying transformer is low consumption transformer. |
| 6. |
Output transformer has 2-dimensional regulating function, which makes center alignment of |
| |
inductor and workpiece be easy. |
| 7. |
This generator also has functions as over voltage, over current and protecting water |
| |
pressure lacking. |
| 8. |
Control circuit has functions as soft starting and voltage stabilizing. |
| 9. |
Numerically-controlled hardening machine, inner circular cooling system and this |
| |
generator constitute complete installation, which has high automaticity, high control |
| |
precision, high consistency of component heat-treating and high percent of pass. |
