The whole set of solid state H.F. welder comprises of switch gear rectifying cabinet, inverter output cabinet, connecting optical fiber, circulation soft water cooling system, central operator console, mechanical adjustment device
Design by the engineer ,high frequency,reasonable price.
High quality welding seam.
1. Switchgear rectifying cabinet
Designed with integration of switch gear cabinet and rectifying part, besides achieving switchgear cabinet functions, it also has rectifying control functions of solid state H.F. welders.
l Installed line-in switch, line-in current meter, voltage meter (can be switched) and line-in voltage indication lamp;
l Installed 3-phase full-controlled thyristor Rectification Bridge to realize power adjustment of the HF welder;
l Installed flat-wave reactor, flat-wave capacitor and filter to improve the flat-wave coefficient.
2. Inverter output cabinet
l 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;
l 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;
l Adopted sealed equipment case, installed with air conditioner.
3. Connecting optical fiber
The rectifying cabinet and the inverter output cabinet are connected with optical fiber, so as to make sure control system can not be disturbed by HF signal, which enhances the reliability of equipment.
4. Circulation soft water cooling system
Air-water heat exchanger is adopted. And circulation soft water is used as cooling water with temperature and water level indicator and protection, which can perfectly accomplish the cooling work for rectifying cabinet, inverter cabinet and resonance tank circuit.
System has automatic digital-display temperature control
Cooler adopts red copper pipe, exterior shell adopts galvanized board, water tank adopts stainless steel material.
5. Central operation console
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,
6. Mechanical adjustment device
Applied to install inverter output cabinet and adjust inductor position.
