Progress and Development Trend on Seismic Measures of Electric Power Equipments in Transformer Substation

The damaged types and reasons of electric power facilities in transformer substation home and abroad under destructive earthquake were summarized.The two kinds of seismic-resistant measures were put forward to deal with the damage of the electric power facilities.The first measure is the traditional seismic-resistant design way that the strength and stiffness of the building and important electric equipments in the building and other facilities are strengthened against the earthquake action,and the measure has already taken a great role against strong earthquake action in the past decades.But the measure can’t ensure the basal function of the building and operating of other important equipments in the building under pre-defined rating strong earthquake.The second measure that adopts isolating technology gets more and more attention.The operating principle of the measure is that the isolating apparatuses between the super-structure and the base or other affiliated apparatuses on the building firstly carries out energy-dissipating action and dissipates a lot of inputting earthquake energy under strong earthquake action,then only less energy was input to super-structure of the building or other electric power facilities so that it can protect the building and equipments in the building or other facilities.Although the isolating technology is widely used in civil building,but it is difficult to be applied in electric power facilities for a lot of puzzles existing in application.It has important and practical significance to carry out isolating application research of electric power facilities in transformer substation.
