The invention provides an ultra-high voltage direct current converter valve anti-seismic performance testing device and method. The ultra-high voltage direct current converter valve anti-seismic performance testing device comprises a converter valve hoisted below a valve hall, a counter-force support connected with the converter valve, and a test device connected with the converter valve; the converter valve comprises multiple strings of long-bar insulators hoisted below the valve hall, valve tower structures, protective shield hoods and lightening arrester strings, and the valve tower structures, the protective shield hoods and the lightening arrester strings are connected to the lower ends of the long-bar insulators; the test device comprises multiple test sensors arranged on the converter valve, and the test sensors comprise the valve tower structures, the protective shield hoods, three-way acceleration sensors arranged on the lightening arrester strings, stress sensors arranged onthe long-bar insulators, and displacement sensors arranged on the valve tower structures and the protective shield hoods. According to the technical scheme, the ultra-high voltage direct current converter valve anti-seismic performance can be detected and verified so as to facilitate optimization design of the structure of the ultra-high voltage direct current converter valve.
