X-RAY FEEDING DEVICE Russian patent published in 2016 - IPC H05G1/10 

FIELD: instrumentation; physics.

SUBSTANCE: x-ray feeding device comprises a module for converting network AC voltage into DC high voltage, in which a low-power supply source has a voltage of ten…thirty kV and power from one half kV to ten kV by means of a switch “Charging”-“Exposure” which is connected to capacitors in parallel when the switch is in “Charging” position, and when it is in “Exposure” position the capacitors are connected in series and are connected to input terminals of the panel for automatic high-voltage control of voltage and the current of anode of the x-ray tube. Switch is made in the form of a glass of an insulating material, filled with insulating liquid; on opposite walls of the glass there are capacitors' terminals, input terminals of the switch are connected to output terminals of the low-power supply source for ten…thirty kV according to the polarity of voltages, and output terminals of the switch are connected to terminals of high-voltage circuit for control of voltage and current of anode of the x-ray tube in the corresponding polarity. Rotor of the switch is installed along the glass axis and is equipped with two pairs of parallel buses connected to capacitor terminals in “Charging” position; in “Exposure” position - by jumpers with output terminals of the switch, earthed by a bridge connecting the right and left capacitor panels and by skewed jumpers connecting, in series, capacitor terminals into a series circuit, and, by output terminals, connected to input terminals of the high-voltage circuit for control of voltage and current of anode of the x-ray tube.

EFFECT: disclosed is an x-ray feed unit.
