摘　　要：由于特高压换流站交流滤波器组设备普遍采用“田”字型布置方式,设备布置空间紧凑,当交流滤波器断路器检修或更换时,必须陪停相应滤波器大组母线,因而严重掣肘换流站的电力外送能力。针对以上问题,研究制作了大型断路器多维移动平台,设计了自立式交流高压测量装置,并在特高压换流变电站750 kV滤波器场应用验证,实现了在不陪停滤波器母线情况下,对800 kV罐式断路器的升降、多维度平移及交流耐压进行试验,提高了检修工作效率,保障了特高压直流安全稳定运行。The‘field’(田)-shaped layout shared by AC filter banks in UHV converter stations,featuring compact equipment layout,demands bus switch-off of filters accordingly during AC filter circuit breaker maintenance or replacement,impeding power transfer capacity of converter stations.In this paper,a multi-dimensional mobile platform of large circuit breaker was studied and manufactured,and a self-supporting AC high-voltage measurement device was designed,which was applied and verified in a 750 kV filter field of UHV converter station.The lifting,multi-dimensional translation and AC withstand voltage tests of 800 kV tank circuit breaker were performed without filter bus switch-off,and thereby the maintenance efficiency was improved,and safe and stable operation of UHVDC transmission was guaranteed.
