PROBLEM TO BE SOLVED: To provide an electrical power substation which can be installed in an area reduced as a whole, has reduced its load to the environment, and can be constructed at a low cost. SOLUTION: A support frame 80a is arranged above transformers 1a, 1b, 1c, 1d, and a primary GIS(gas-insulated switchgear) 90c and a secondary GIS 90d are arranged on this support frame 80a. Namely, it is possible to utilize a space in three directions and approximately halve an installation area by arranging the GISs 90c, 90d above the supporting frame 80a and arranging the transformers 1a, 1b, 1c, 1d below the frame respectively, and adopting a hierarchical structure. |
