Description

Technical Field

[0001] The present invention relates to the technical field of voltage-equalizing shielding rings, in particular to a voltage-equalizing shielding ring for a four-split conductor tension string and an installation method thereof. Background Art

[0002] The grading shielding ring is generally installed at the conductor clamp on lines of 330kV and above. Since the voltage borne by the insulator string of the transmission line is not evenly distributed on each insulator, the voltage borne by the insulator in the middle of the string is smaller than that at the two ends, and the distributed voltage borne by the insulator close to the conductor is the largest. This uneven voltage distribution becomes more serious as the line voltage increases. In lines of 330kV and above, insulators close to the conductor are prone to corona and radio interference. Installing the grading shielding ring can make the voltage distribution of the insulator string more uniform.
