摘要

Experiences of past earthquakes have shown high vulnerability of high voltage power substations'equipments under seismic actions due to fragility and sensitivity of their components and insulators. Thecommon seismic design practice concerning power substations had been to design the equipments in orderto resist a specified lateral acceleration (0.3g) statically, for many years. Although this seems to be veryinsufficient regarding dynamic behaviour of equipment mounted on structure, but it looks inevitableconsidering actual operational requirements and mechanical characteristics of equipments and theircomponents.with innovation made in the field of energy dissipation and base isolation systems supportedby earthquake simulation and shaking table technology along with progresses made in structural nonlineardynamic analysis topics and also new horizons in the domain of ductile materials and insulators,regulations restricted the seismic performance of power substations more severely and emphasized ratheron seismic protection of equipments. In this paper the seismic design of structures of one bay ofNeishabour's 400kV substation extension using elasto-plastic U-shape energy dissipators located between2 plates has been presented. Two of the most vulnerable equipments namely, Circuit Breaker and CurrentTransformer have been investigated and typical sandwich interface devices have been designed to beinserted between foundation and structure or structure and equipment. Three layouts for U-shape elementshave been considered and tested through cyclic loading tests to check their energy dissipation capacity.
