Application Scope

The plasma gas generator, monocrystalline silicon zone melting, woods, food drying, steel tube welding, high frequency quenching


     

Function Structure

For frequency more than 1MHz or other low cost application filed, vacuum tube high frequency power supply still has an irreplaceable position and wide application. 


Vacuum tube high frequency power supply adopts AC-DC-AC frequency variable structure. Convert power frequency AC voltage to adjustable high voltage DC voltage through the matching of 3-phase AC voltage regulation circuit, step-up transformer and high voltage silicon rectifier stack (6-pulse wave or 12-pulse wave). Oscillating circuit adopts high frequency large power vacuum tube to produce self-oscillation. Resonant circuit can adopt single circuit or three-circuit mode. 


The whole unit of equipment is composed of AC voltage regulation cabinet, step-up transformer, vacuum tube oscillating cabinet and tank circuit cabinet, circulation soft water cooling system, console and positioning table.
