Switchgear rectifying cabinet
Designed with integration of switchgear cabinet and rectifying part, besides achieving switchgear cabinet functions, it also has rectifying control functions of solid state H.F. welders.
Installed line-in switch, line-in current meter, voltage meter (can be switched) and line-in voltage indication lamp.
Installed 3-phase full-controlled thyristor Rectification Bridge to realize power adjustment of the HF welder.
Installed flat-wave reactor, flat-wave capacitor and filter to improve the flat-wave coefficient.
The inverter part is consisted of MOSFET single-phase inverter bridge connected in parallel. The power of single-phase bridge is 120kW; the inverter bridge adopts the building block method to realize power superposition. Every piece of bridge plates is designed in the shape of a drawer, which is very easy to install and repair.
The matching transformer is adopted for power combination, also it adopts the output method by of secondary resonance and non-welding transformer, tank circuit resonance capacitor (low voltage) resonates with the sensor directly, and the output pole plate offers required power transmission for pipe welding.
Adopted sealed equipment case, installed with air conditioner.
It realizes solid state H.F. welder remote operation and power regulation, installed with LCD which indicates armature voltage, field voltage indication and of DC drive and DC voltage, DC current indication of H.F. welders.
Circulation soft water is used as cooling water with temperature and water level indicator and protection.
Applied to install inverter output cabinet and adjust inductor position. 2D and 3D adjustable.
