Abstract

UHV Xinsong Converter Station is the highest elevation and seismic fortification requirement in the world at present.The seismic design and assessment of its DC field equipment is the core content of the seismic design of the whole converter station.Firstly

the basic idea of anti-seismic decoupling design of DC yard equipment is introduced

and the structural characteristics and weak links of DC yard equipment are analyzed.The DC yard main equipment is divided into several independent coupling circuits.Secondly

the seismic fortification level and main ground motion parameters of DC yard equipment of converter station are put forward.By choosing composite materials

optimizing bracket and equipment structure

innovating equipment connecting conductors and fittings

adopting isolation and shock absorption

the seismic performance of main electrical equipment in DC field of converter station can be effectively improved.Through carrying out the seismic calculation and shaking table test of the UHV electrical equipment

the results show that the main UHV electrical equipment of Xinsong converter station has the ability to withstand the strong earthquake of 400 Gal deterministic site wave.Relevant research and application provide an effective solution for the seismic design of converter stations in similar areas with high seismic intensity in the future.
