Abstract:
An X-ray apparatus comprising:a d.c.-a.c. converter circuit adapted for connection to an energy source, said d.c.-a.c. converter circuit having a housing and having a circuit location therein which is at a constant potential; an X-ray tube; a high-voltage transformer connected to said X-ray tube for generating high-frequency operating voltage and supplying said high-frequency operating voltage to said X-ray tube, said high-voltage transformer having a housing and containing a transformer device component; and a line connection connecting said d.c.-a.c. converter circuit to said high-voltage transformer, said line connection comprising first, second, third and fourth concentrically arranged conductors, said first and second conductors being innermost conductors and carrying operating voltage and having a first insulating layer therebetween with said first and second conductors being close to each other for producing a low line inductance and each of said first and second conductors having a ratio of conductor radius to conductor thickness for producing a low ohmic impedance, a third conductor separated from said second conductor by a second insulating layer and eliminating capacitive shift currents and being connected to said location at constant potential in said d.c.-a.c. converter circuit, and a fourth conductor separated from said third conductor by a third insulation layer, said fourth conductor forming a shielding conductor and being connected to said housing of said d.c.-a.c. converter circuit and to one of said housing of said high-voltage transformer and said device component in said high-voltage transformer.
