<p><P>PROBLEM TO BE SOLVED: To provide a gas-insulated opening/closing device that can reduce installation space in an extension direction of main busbars and can also reduce the amount of thermal expansion and contraction of the main busbars. <P>SOLUTION: Main busbars 1 and 2 constitute a double busbar. The main busbars 1 and 2 are extended linearly in one direction and are then folded back in a U-shape in the same direction by main busbars 1a and 2a. All of a transmission line unit U1, a busbar instrument transformer unit U2, a transmission line unit U3, a transformer unit U4, a busbar communication unit U5 and a transformer unit U6 are arranged outside the main busbars 1 and 2, and are respectively connected to the main busbars 1 and 2. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
