<p>PURPOSE:To reduce the area of a site and to delete the cost of civil engineering and construction for a substation facility by disposing switching devices by air insulation on the roof of a building for containing gas insulated switching devices. CONSTITUTION:Indoor gas insulated switching devices 107, 207 of high voltage side and indoor gas insulated switching devices 108, 208 of other channel are contained in a first building 21. A lead-in steel tower 22 is provided on a roof top 21a, line traps 104, 204 are hung, and gas-insulated bushings 105, 205, arresters 102, 202 and transformers 103, 203 for an instrument are disposed. A second building 23 is build adjacent to the building 21, and indoor gas insulated switching devices 112, 212 of low voltage side and indoor gas insulated switching devices 113, 213 of other channel are contained therein. The buildings 21, 23 are constructed in an integral structure, and its interior is divided by a partition wall.</p> |
