<p><P>PROBLEM TO BE SOLVED: To provide a gas-insulated switchgear with a structure for arranging a vertical interrupting section in which inspection of the vertical interrupting section and replacing work of a contact part can be carried out easily. <P>SOLUTION: A vertical interrupting section 6 is arranged in a container 1 forming a manhole 5 being closed with a removable cover 5a at an upper portion, power supply side is connected to one side face of the container 1, and a first current transformer enclosure for arranging a current transformer 7 and a second current transformer enclosure for arranging a current transformer 8 are fixed to the other side face. A first current transformer conductor 11 penetrates the transformer 7 in the first current transformer enclosure 2 and turns back into the container 1 thence passes above the vertical interrupting section 6 before being connected with the power supply side conductor 9. A second current transformer conductor 12 penetrates the current transformer 8 in the second current transformer enclosure 3 before being connected with the load side. An intermediate conductor 10 is interposed between the power supply side conductor 9 and the first current transformer conductor 11 and located oppositely to the manhole 5 with one end being secured removably to the power supply side conductor 9, and the other end being connected removably with the first current transformer conductor 11 through a fitting means 17. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
