Along with the rise of voltage level and the complicating of operation environment, the traditional structure faces multiple challenges in engineering application, the self structure of the composite insulator causes extremely uneven distribution of an electric field along the surface, water droplet corona discharge is easy to be caused in a humid environment, material aging is accelerated, and flashover is caused seriously. For example, the 500kV compact circuit can control the peak value of the electric field intensity on the surface of the umbrella skirt within a safe range by optimizing parameters of the equalizing ring, and corona discharge can occur at the fixing bolt of the equalizing ring due to electric field concentration in the places such as ultra-high voltage direct current circuit, so that the electric corrosion of the bolt is caused, and the structure is threatened to be stable. The grading ring design is required to be fine in consideration of field intensity control of all components, the grading ring used in ultra-high voltage engineering is large in size (the ring diameter can reach the meter level), the integrated structure brings great difficulty to transportation, hoisting and installation of narrow construction sites such as mountain areas and fields, the operation risk and cost are increased, and the pipe diameter, the ring diameter and the installation position (shielding depth) of the grading ring are required to be optimized in a personalized manner according to different circuit parameters (voltage, tower type and insulator type) and operating environments.
