GROUNDING METHOD OF EXTRA-HIGH VOLTAGE TRANSMISSION LINE

摘要

PURPOSE:To complete grounding by installing a let-off motion for a ground rod between a tower body or a steel tower arm and delivering the ground rod by the let off motion while the mounting object of the ground rod is collimated by the nose of the ground rod. CONSTITUTION:A ground rod 10 is held between a rotary belt 2 composed of a rubber and a roller 3, a surface of which has a rubber lining 3a, and a handle 4 is turned, thus forward moving or retreating the ground rod 10. The ground rod 10 is delivered collimated to a grounding horn 25, a line side clamp at the nose of the ground rod 10 is clamped to the grounding horn 25, and a grounding side clamp at another end of a grounding cable 11 is tightened and fixed to the steel tower side, thus completing the grounding of an electric cable 20.
