The calculation method of steady-state field was analyzed in the paper.Based on the structure of UHVDC bus bar MOA
a 3-D finite element model was established;the potential and electric filed distribution of the bus bar MOA under the continuous operating voltage was calculated.The result showed that under DC voltage
arrester valves withstand the same voltage;the main effects of anti-corona rings were reduce the partial high electric field strength
and prevent the corona.Meanwhile
the structure of the anti-corona rings was optimized in this paper.
