Optimum seismic fortification level forelectrical equipment in substation

摘要

We determined the seismic fortification level of electrical equipment in this paper according to the features of seismic failures in substation, provisions about seismic fortification level standard, and decision about optimum seismic fortification for electrical equipment, we also classified the seismic fortification level according to seismic reliability calculations and reliability results, put forward a high, medium and low seismic fortification level system.
