In order to relatively uniformly arrange the stress balance fixing plates in use, the number and the size of the fixing plates can be set according to the weight and the volume of the equalizing ring, and the invention is not limited. Referring to fig. 4, fig. 4A, B is a side view and a front view of the limiting support leg 2, respectively, the horizontal step section is parallel to the annular body 1, and the length of the vertical step section beyond the lower edge of the annular body 1 is 15-20mm. Referring to fig. 5 in combination, fig. 5A, B, C is a left side view, a front view and a top view of the rigid connection member 4, respectively. If the rigid connecting piece 4 is L-shaped, the L-shaped vertical section is provided with a second threaded hole 5,L which is matched with the connecting bolt 7, the L-shaped horizontal section is provided with a mounting hole 6, and the rigid connecting piece 4 can be made of aluminum material in consideration of welding with an aluminum material equalizing ring.
The side-mounted equalizing ring is designed by matching with cylindrical high-voltage test equipment, and therefore, the invention also provides an installation method, which comprises the following steps:

Secondly, placing a grading ring: the circular ring body 1 is sleeved on the periphery of the top of the cylindrical high-voltage test equipment 8, so that the stepped limit support legs 2 are clamped on the side wall of the cylindrical periphery, and the limit support legs can play a role in clamping when being fixed on the inner side of the circular ring body in a triangular distribution mode, but if the circular ring body is cylindrical high-voltage test equipment with larger size, the number and the installation angle of the limit support legs can be redesigned, and the circular ring high-voltage test equipment is not limited in the invention.
Then, the ring body 1 is rotated so that the second screw hole 9 on the fixing plate 3 overlaps the first screw hole 5 on the vertical section of the L-shaped rigid connection member 4.
Thirdly, installing a grading ring: the equalizing ring is mounted on the top of the high-voltage test equipment by using a connecting bolt 7 to penetrate through a first threaded hole 5 formed in the vertical section of the rigid connecting piece 4 and a second threaded hole 9 formed in the fixing plate, and the mounted state is shown in fig. 7 and 8.
