The switch cabinet and rectifier are designed integrally, which not only completes the function of switch cabinet, but also has the rectifier control function of solid-state high-frequency welding machine, which is also called thyristor(SCR) welding machine
Switch Rectifying Cabinet--- main parts of solid state HF Welder
●Install incoming disconnect switch,incoming current meter, voltage meter(switchable) and incoming voltage3 indicating light.
●Install 3-phase full-controllable thyristor rectifying bridge to achieve power regulation of H.F. welders.
●Install flat wave reactor,flat capacitor and filter to increase semi-wave coefficient.
Inverter Output Cabinet--main parts of solid state High Frequency Welder
●The inverter part is consisted of MOSFET single phase invert bridge in parallel style. Each bridge’s design power is 120kW/60kW.We adopt building block mode to pile up power,it’s very convenient to install and maintain because every bridge board is designed as drawer structure consisted of slide way.
●We adopt matching transformer to realize power combination,also we adopt sub-resonance capacitor(low voltage) and inductor to achieve steel pipe welding power transmission by output lead.
●Use sealed box and install overhead air conditioning.
Solid State High Frequency Welder
HMI and fault diagnosis system
●Adopt PLC and touch screen to form perfect HMI system.
●Realize integrated automatic control of welder system.
●Fault display and diagnosis system.
