Abstract: Seismic performance is meaningful for high voltage disconnect switchwhich is vulnerable to the earthquake for its long
spangreat heightand flexibility In this papera full-scale shake table test on 800 kV three-post disconnect switch is carr ied out to
obtain its dyna mical properties and seismic responses laws The effect on disconnect swi t c h's posts caused by the main blade is studied
in different direction via characteristics of acceleration amplification factor and the spectrum analysis method The results indicate the
space lattice tilted structure form can limit the adverse impacts on seismic responses induced by the height and flexibility of the equip-
ment Meanwhileafter the main blade closeda ce r t a i n constraint effect will occur in the along-span directionwhile in the across-
span direction constraint effect is weak The constraint effect can amplify and reduce the seismic responses of the post with blade and
the post with fixed contact respectively
Key words: disconnect switch; shake table test; seismic responses; amplifi cation factor; constraint effect
