The invention relates to a method for a corona test of an ultrahigh voltage AC transmission line rigid jumper, namely under the condition of plane simulated arrangement, the corona test of the ultrahigh voltage AC transmission line rigid jumper is carried out, and the coefficients are corrected according to the position so as to obtain the corona parameters of the rigid jumper on the transmission line. Due to the plane simulated arrangement, the arrangement of the rigid jumper of a project is simplified, the difficulty and the workload of the test arrangement are lowered, the corona characteristics of key parts of the rigid jumper and the corona voltage of main anchor clamps of the rigid jumper can be obtained, and the plane simulated arrangement also has guiding significance in different jumper plans and designs. Moreover, the plane simulated arrangement has good effects on side phase direct jumper simulation, and because the coefficients are corrected according to the position, the corona voltage under the condition of actual operation can be obtained according to the results of the corona test.
