Abstract
In order to study the seismic performance of electrical equipment in the coupling circuit of con-verter stations in high altitude and high intensity areas,the author establishes a simulation model for the coupling circuit of composite post insulators connected by hard and soft conductors.The bending stiffness of the flange connection of the composite post insulator and the mechanical parameters of the sliding hard-ware in the hard tube bus connection circuit are considered,and the dynamic characteristics and seismic response analysis of the circuit are carried out.The influence of high sea level and high intensity on the seismic response of coupled circuit equipment was studied.The research results indicate that in the cou-pling circuit of composite post insulators connected by hard tube buses and soft wires,the seismic re-sponse of the equipment becomes more and more significant with the increase of seismic acceleration le-vel,and the root stress and top displacement response of the equipment show a linear increasing trend;As the altitude increases,the maximum stress response at the root of the hard tube bus connected circuit equipment increases by about 10%,and the maximum displacement response at the top of the equipment increases by about 32%.The displacement response at the top of the soft wire connected circuit equip-ment increases by about 16%.At the same time,the influence of the sag of the soft wire on the seismic response of the circuit equipment was studied,and a calculation formula for the length of the soft wire was obtained to reduce the seismic coupling effect of the soft wire connected circuit equipment.关键词
