GENERATOR OF POWERFUL CURRENT PULSES FOR INTENSIFICATION OF METAL PLASTIC WORKING PROCESSES

摘要

FIELD: electricity.;SUBSTANCE: generator of powerful current pulses comprises charging device, capacitor, connected to charging device via switching device, including device, load connected serially to capacitor, generator of control pulses, unit of protection and power amplifier of control pulses, outputs of control pulses power amplifier are connected to switching and connecting devices, at the same time it comprises n channels connected to network with various groups of connection of power and control transformers and parallel to load, in each channel generator of controlled pulses comprises differentiating link in the form of capacitor and generates control pulses of sinusoidal shape from pulsations of rectified voltage in rectifier connected to circuit, both for switching device and connecting device, and controls both switching device and connecting device in turns.;EFFECT: production of power current pulses with strictly specified parameters by amplitude and possibility to produce working pulses with amplitude of up to 30 kA and frequency of up to 3600 Hz, which will make it possible to considerably increase diameter of processed metal profiles.;3 dwg
