Power tower insulating foundation achieved based on conductive rubber

Abstract

The invention provides a power tower insulating foundation achieved based on conductive rubber. The power tower insulating foundation comprises a leading-out connecting line led out from a pole foundation, wherein the leading-out connecting line is buried underground and is jointed with sacrificial anodes; the sacrificial anodes are arranged around the pole foundation; the sacrificial anodes have framework structures; the peripheries of the sacrificial anodes are filled with conductive rubber; the conductive rubber is filled with carbon dust; the sacrificial anodes are connected with a seal joint; an anode cable is led out from the seal joint and is jointed to the leading-out connecting line led out from the pole foundation. By adopting the power tower insulating foundation, the peripheries of the anodes are filled with conductive rubber to prevent corrosive liquid in soil from permeating, thus prolonging the service lives of the anodes; when larger current is generated, the anodes outside the foundations are first corroded, thus playing a role in protecting rebars (cathodes) inside the foundations and then protecting the whole pole and tower foundations.

Description

technical field [0001] The invention relates to an insulation foundation of an electric power tower, and more particularly relates to a sacrificial anode protection in an AC UHV double-circuit insulation foundation type on the same tower. Background technique [0002] In the prior art, insulation is not considered in general engineering foundation types. However, when the grounding pole is in fault, overhaul or single-pole operation, a large ground current will be generated. The tower foundation near the grounding pole will be affected by the ground current near the grounding pole for a long time, and the internal steel bars of the foundation will be corroded. As the use time increases, the foundation may be damaged, which will eventually lead to the destruction of the iron tower on the foundation, so as to destroy the safe operation of the entire transmission line. [0003] When the DC grounding electrode is close to the high-voltage transmission line, it will corrode the ...

AI Technical Summary

Problems solved by technology

[0004] The utility model patent No. 201020690219.6 also provides an insulating foundation, but in the foundation, the problem of soil corrosion liquid penetration is not considered

Therefore, when the corrosive liquid in the soil enters the soil, it will corrode the anode, which greatly reduces the service life of the anode and cannot really protect the foundation of the power tower.
