Specific implementation mode
The embodiment of the power transmission tower earthing or grounding means is described in further detail below in conjunction with the accompanying drawings：
The power transmission tower earthing or grounding means is made of tower body 1, earth bus 2, down conductor 3, grounding body 4；Tower body 1 is by lead
Chamber 1-1, tower leg 1-2, column foot 1-3 compositions；Perforation makes leaded chamber 1-1, lead chamber in the tower leg 1-2 and column foot 1-3 of tower body 1
1-1 is built-in to be equipped with earth bus 2, and earth bus 2 is connect with down conductor 3；Grounding body 4 is by fixed plate 4-1, shell 4-2, drop
Resistance layer 4-3, grounding rod 4-4, conehead 4-5, earthing block 4-6 compositions；The bottom surfaces fixed plate 4-1 are welded with shell 4-2, in shell 4-2
Wall making has drop resistance layer 4-3, and grounding rod 4-4 is equipped in drop resistance layer 4-3；Shell 4-2 lower welds have conehead 4-5；Grounding rod
The tops 4-4 are equipped with earthing block 4-6, and grounding rod 4-4 is connect by earthing block 4-6 with down conductor 3.
The down conductor 3 is made of electric wire 3-1, protective case 3-2, anti-corrosive cover 3-3.
