DEVICE FOR GENERATING ELECTRIC SPARKS OF A GIVEN ENERGY FOR CALIBRATION OF PHOTO-RECORDING EQUIPMENT Russian patent published in 2022 - IPC H01T14/00 H03K3/537 

FIELD: testing equipment.

SUBSTANCE: invention relates to the field of control and testing of aircraft systems containing a fuel-air mixture for resistance to lightning discharges. Essence: the device for generating electric sparks for calibration of photo-recording equipment contains a charging unit, working and storage capacitors, a static kilovoltmeter, a light-tight chamber, electrodes forming a working spark gap for the formation of a single spark located inside the light-tight chamber, electrodes forming an auxiliary spark gap identical to the working spark gap to ensure the discharge of the storage capacitor located outside the light-tight chamber. cameras, a dielectric shield with slit, located between the electrodes forming the auxiliary spark gap, perpendicular to the axis of the auxiliary spark gap, the unit of movement of the dielectric shield. The storage capacitor is connected to one of the electrodes forming an auxiliary spark gap and to the charging unit. The working and auxiliary spark gaps are connected in series. The capacity of the working capacitor is 8-10 pF with the possibility of accumulating maximum energy of no more than 400 mcJ. The capacity of the storage capacitor is at least 2 orders of magnitude higher than the capacity of the working capacitor.

EFFECT: possibility of creating a single spark with an energy of 200 mcJ for calibration of photo-recording equipment.
