IONISER Russian patent published in 2010 - IPC H01T23/00 

FIELD: electricity.

SUBSTANCE: invention relates to gas discharges procedure. In blown ionising chamber there are needle electrodes fixed coaxially, which are connected to secondary winding of pulse transformer in high-voltage unit with a voltage detector in circuit of step-down winding of feedback, providing for ionisation of spark breakdown between electrodes. Stability of ions generation process is achieved by application of breakdown pulses frequency and voltage level control depending on speed of blowdown and condition of environment. This circuit is arranged with scaling voltage converters, connected accordingly to detector of mass flow rate of air installed at the inlet of ionisation chamber, to voltage detector and to differentiating circuit, and also discriminator and voltage converter into frequency.

EFFECT: invention provides for control of spark breakdown frequency depending on speed of blowdown and condition of gas medium.
