A hydro-electricity arrangement of a special high-tension is provided to decrease an installation space by reducing a number of panels and arranging a PT panel and an incoming panel densely. A high voltage apparatus of each panel is installed at one panel as a modulized case. A load breaker switch and an arrestor which are three-stage switches, are installed at an upper part of one panel. A current limitable fuse guaranteeing an insulation by an insulating agent is mounted at a middle of the one panel, and a high voltage transformer and current transformer insulated by the insulating gas are formed at a lower part of the one panel. A disconnector and a ground switch are mounted at the upper part of the one panel together. A breaker module and a current transformer are mounted at the middle of the one panel together, and a bus-bar transformer and a protective fuse are formed at the lower part of one panel together. And, a required number of the modulized load breaker switches linked with the current limitable fuse are stacked at one panel. |
