摘要：

To　explore　better　the　anti-seismic　performance　of　some　high　voltage　switchgear,　sine　frequency-swept　wave,　sine　resonance　beat　wave　and　the　actual-record　seismic　waves　are　applied　by　the　shaking　table　on　real　full-size　switchgear.　The　experimental　results　show　that　the　longitudinal　natural　frequency　of　vibration　is　about　10.74　Hz,　and　that　the　transverse　is　about　2.69　Hz.　Breaker　and　some　key　connecting　parts　with　bus　vibrate　stronger.　As　the　weak　link,　they　should　be　paid　more　attention　when　designed.　After　the　multiple　earthquake　waves　with　different　frequency　spectrum　characteristics,　switchgear　behaves　a　normal　function　as　before　and　the　main　connection　components　do　not　damage　apparently.　The　stress　values　of　root　sections　of　insulator　are　able　to　satisfy　the　requirements　of　the　code.　©,　2015,　Xi＇an　High　Voltage　Apparatus　Research　Institute.　All　right　reserved.
