Problems solved by technology

[0002] During the daily detection of cables, in order to ensure that there is no potential difference between the various parts of the detection equipment and distribute the high voltage evenly around the object, a voltage equalization ring is usually installed on the detection equipment. However, the existing voltage equalization ring needs It is installed on the detection equipment through connecting rods, etc., and in order to improve the pressure equalization effect, multiple pressure equalization rings are usually installed on the detection equipment. These pressure equalization rings need to be installed separately, which increases the difficulty of installation and the installation efficiency is not high; and workers It is difficult to ensure that the distance between the pressure equalizing ring and the detection equipment is consistent during installation, which will affect the pressure equalizing effect
Therefore, the existing technology has the problems of troublesome installation and unsatisfactory pressure equalization effect.
