Abstract:
1. An X-ray generator comprising: a one-side earthed type X-ray tube wherein anode or cathode is earthed; high-voltage generating means for generating X-rays by applying DC high-voltage between the anode and cathode of the X-ray tube; a power source for providing electric power to the high-voltage generating means; a discharge current suppressing resistor connected between one end of DE output of the high-voltage generating means and the anode or cathode on the side that the one-side earthed type X-ray tube is not earthed, for suppressing discharging current of the one-side earthed type X-ray tube; tube voltage detecting means for detecting tube voltage applied between the anode and the cathode of one-side earthing X-ray tube; tube current detecting means for detecting tube current flows between the anode and the cathode of the one-side earthed type X-ray tube; discharge portion identifying means for identifying, upon occurrence of a discharge in the X-ray generator, where in the high-voltage generating means or the one-side earthed type X-ray tube the discharge occurred based on the tube voltage detected value detected in the tube voltage detecting means and the tube current detected value detected in the tube current detecting means; and display means for displaying the discharging part identified in the discharge portion identifying means.
