<p><P>PROBLEM TO BE SOLVED: To obtain an insulating structure of a switchgear which can reduce an electric field of a triple junction. <P>SOLUTION: In the insulating structure of the switchgear in which a main circuit of a switching apparatus is accommodated in a grounding metal case filled with an insulating gas, and which insulates main circuit conductors constituting the main circuit, or the main circuit conductors and the grounding metal case, the structure is constituted such that a large cross section part 11a enlarged in cross section larger than a region 11a other than an opposing end is formed at the opposing end of an electrode 11 which opposes a grounding part 12 with at least the smallest gap L between, or at the opposing end of the electrode 11 that opposes the grounding part on a small curvature face, and an insulating layer 13 is coated on the surface of the large cross section part 11a. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
