<p><P>PROBLEM TO BE SOLVED: To acquire an insulation structure of an electrical device for improving a voltage withstanding performance of an insulation system having an insulation barrier between conductors, and a switchgear using the insulation structure. <P>SOLUTION: In the insulation structure of the electrical device, a high voltage side conductor 1 (the first conductor) having a curved section 1a formed with a predetermined curvature at an end, is disposed within an insulation gas, facing the grounding conductor 2 (the second conductor), and a saucer-shaped insulation barrier 3 for covering the curved section 1a of the high voltage side conductor 1 and a portion of a side face 1b connected to it is provided opposite to the high voltage side conductor 1 through an air gap. A distance A of the air gap between a tip of the high voltage side conductor 1 and an inner surface of the insulation barrier 3 is formed so as to be larger than a distance B of the air gap between the side face 1b of the high voltage side conductor 1 and the inner surface of the insulation barrier 3. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
