±800kV穿墙套管的地震响应与振动控制
Seismic Responses and Vibration Control of ±800 kV Wall Bushing
摘要
Abstract
UHV (ultra-high voltage) DC (direct current) wall bushings are the important equipment of converter substation and are vulnerable in the earthquake.In order to evaluate wall bushing's seismic performance,an ±800 kV wall bushing finite element model is established and its seismic responses is obtained.And to solve the problem that the seismic responses are too large to meet the engineering requirements,metal friction type dampers are proposed to be installed at the bottom of the wall bushing and the seismic responses of the wall bushing with and without dampers are compared.The result shows that the existence of metal friction dampers could reduce the acceleration and stress of the wall bushing,among which the acceleration at the top of the bushing reduced 34％ and the stress at the root of the bushing reduced 54％,so the vibration control effect is significant.Wall bushing with metal friction dampers could meet the seismic requirements,so the existence of dampers could greatly improve the seismic performance of the wall bushing.关键词
