2.Inverter Output CabinetThe invert part is considered of MOSFET single phase invert bridge in parallel style. Each bridge’s design power is 120 KW/60KW. We adopt building block mode to pile up power,it is very convenient to install and maintain because every single bridge board is designed as drawer structure consisted of slideway.We adopt matching transformer to realize power combination, also we adopt sub-resonance, no-welding transformer output mode and make resonance directly by tank resonance capacitor(low voltage)and inductor to achieve steel pipe welding power transmission by output lead.Use sealed box and install overhead air conditioning.
3.Central ConsoleThe console achieves remote control and power regulation of solid-state H.F. welder, installed with LCD; also it has indicators of armature voltage, field voltage on DC speed regulation cabinet and indicators of DC voltage, DC current on welder. Installation of power-speed closed loop control function is optional. The consolehas design difference according to different types and quantities of matching DC speed regulation cabinet.
