Summary:The utility model relates to a bushing grading ring for main partial discharge test. The bushing grading ring comprises a sleeve, the upper end surface of the sleeve and the lower portion of the sidewall of the sleeve are provided with support columns which are distributed symmetrically by taking the axis of the sleeve as the symmetric axis, the upper end of the support column at the upper end surface of the sleeve is connected with an upper ring, and the lower end of the support column in the lower portion of the sidewall of the sleeve is connected with a lower ring. The bushing grading ring is simple in structure and convenient to install, can effectively make the electric field caused by high voltage at the top end of the bushing uniform, and thus, prevents test from being interfered by corona which is generated by non-uniform electric field at the top of the bushing.
