<p><P>PROBLEM TO BE SOLVED: To obtain a switchgear wherein the dimension in the height direction can be reduced by miniaturizing a container. <P>SOLUTION: A sealed container 3 in this switchgear with an insulating gas filled thereinto to store main circuit apparatus is divided airtight into three sections of an upper side apparatus chamber 3a, a bus bar connection chamber 3b, and a lower side apparatus chamber 3c; and arranged in the vertical direction inside a box 2. A bus bar 4 is arranged at the outside-chamber side of the back side center of the bus bar connection chamber 3b. Two units of three-position isolators 16, 17 are arranged symmetrically in the vertical direction inside the bus bar connection chamber 3b. Fixing side terminals 16a, 17a of each of the three-position isolators 16, 17 are connected to the main circuit apparatus of the chambers adjacent via partitioning bushings 14. Each of input side terminals 16b, 17b is connected to the bus bar 4 via bus bar bushings 25. Each of ground side terminals 16c, 17c is connected to an insulating terminal 22, which is penetrated and provided in a mounting board 15 at the front side of the bus bar connection chamber 3b. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
