PURPOSE:To improve the dielectric strength of a connection member such as a slip ring with an air by equipping with an enclosure to house the connection member and a humidity absorbing member to reduce the humidity of the internal space of the enclosure. CONSTITUTION:A CT device constitutes an enclosure 4 housing a slip ring 3 to execute a high voltage feeding to an X-ray tube by means of a rotor 1 to fit an X-ray tube, etc., and a stator 2 of the coaxial construction as the rotor 1. A dehumidifier 6 communicated through a pipe 5 to the internal space of the enclosure 4 is equipped. The dehumidifier 6 communicated through the pipe 5 to the internal space of the enclosure 4 functions to remove the water from the internal space of the enclosure 4 during the operation. For that reason, the slip ring 3 is surrounded at the air to reduce the humidity, namely, the dry air and the dielectric strength can be improved. |
