METHOD OF HIGH-VOLTAGE PULSE SYSTEM OPERATION Russian patent published in 2019 - IPC B02C19/18 

FIELD: electronic equipment.

SUBSTANCE: group of inventions relates to a method of grinding materials by high-voltage pulses, a high-voltage pulse system and use thereof for grinding materials with poor electrical conductivity. Method of operating a pulse system comprising an energy storage unit for providing energy for high-voltage pulses and a charging device for charging an energy storage device, the method involves generating a series of high-voltage pulses at each of which the energy accumulator is completely discharged and recharged for the next high-voltage pulse after the pause of the charging is completed by supplying the charging energy with the help of the charging device. At that, when switching the system from operation in high-voltage pulse mode to idle state, in which energy accumulator is discharged and protected against unintentional charging, energy accumulator is short-circuited and/or grounded during charging pause. High-voltage pulse system comprises energy accumulator, charging device, one or several short-circuiting or grounding switches for protection of energy accumulator against unintentional charging by short-circuiting and/or grounding and system control device. At that, the system control devices are configured to control the system such that when operating in high-voltage pulse mode, the system generates a series of high-voltage pulses, wherein the energy accumulator is completely discharged at each high-voltage pulse and repeatedly charged for the next high-voltage pulse after the pause of charging by supplying charging energy by means of the charging device.

EFFECT: operating method of pulse system and pulse system ensure reduction of expenses at grinding of material, in particular, due to absence of necessity to use large amount of insulating oil.
