<P>PROBLEM TO BE SOLVED: To provide an inexpensive and readil assemblable DC-gas insulated bus-bar that achieves improvement in insulation reliability, by suppressing the movement of metallic foreign matters. <P>SOLUTION: The DC-gas insulated bus-bar is composed as follows. A high-voltage conductor 2 is arranged at the center of a cylindrical metal container 1 and along in the axial direction of the container. A thin-plate shield 3, bent into a semicircular shape with a curvature larger than the radius of the high-voltage conductor 2, is mounted to the lower part of the circumference of the high-voltage conductor 2 so as to have the same potential. By this, the radius of the lower part of the high-voltage conductor 2 is increased in a pseudo manner so as to be capable of reducing an electric field. <P>COPYRIGHT: (C)2008,JPO&INPIT |
