Application of isolation technology in electsic power building

At present, isolation technology is mainly used in dwelling houses and very fewer offices building inland while seldom used in lifeline construction such as electric power buildings. It has shown from so many earthquake destroy examples that seismic reliability of electric power system must be strengthened and its research has become one of the important tasks. Especially, how to insure the common work of substation in different conditions are the emphases in seismic research. This paper based on the real engineering - 110kV Switch building in a substation designs isolation layer for it. It is used 3-d FEM as calculation model and laminated rubber bearing as isolation layer. The authors using SAP2000N program compute the nonlinear dynamical time history response. Comparing the reaction between seismic building and isolation building, the authors receive some beneficial conclusions. The results in this paper will become a good base for the wider using of isolation technology in electric power system.
