An anti-theft combined copper-clad steel grounding electrode and its installation method

Abstract

The invention discloses an anti-theft combined copper-clad steel grounding electrode, which comprises: a driving head, a copper-clad steel grounding rod, a connecting part and a drill bit, and the copper-clad steel grounding rod is respectively connected with the driving head, the connecting part and the drill Connection; the drill bit is a large conical head, the outer diameter is at least twice the diameter of the ground rod; the driving head is a large cylindrical shape, the outer diameter is not less than the outer diameter of the conical drill bit, and the upper and lower sides of the cylindrical driving head are close to the outer ring. There are several small hollow cylindrical holes. At the same time, the installation method of the anti-theft combined copper-clad steel grounding electrode is disclosed. Through the small cylindrical hole, conductive cement and resistance reducing agent are injected into the space of the grounding hole hammered into the soil layer. This kind of ground electrode and its installation method fully increase the difficulty of the theft of the copper-clad steel ground electrode, can effectively reduce the theft loss rate of the copper-clad steel ground electrode, enhance the safety and stability of the power line equipment operation, and to a certain extent It reduces the complexity of knocking and installing the ground electrode.

Description

technical field [0001] The invention relates to the technical field of power system security devices, in particular to an anti-theft combined copper-clad steel grounding electrode and an installation method thereof. Background technique [0002] The grounding electrode is the grounding product that must be used in the current distribution network power line equipment grounding project. In severe thunderstorm weather, when electric equipment is struck by lightning, the grounding electrode can quickly discharge the lightning current into the ground to prevent lightning accidents on electric equipment. At present, the grounding products used in the power equipment lines of the distribution network include galvanized angle iron, zinc-clad round steel, copper-clad steel, pure copper rods, electrolytic ion grounding electrodes, grounding modules, etc. Among them, the copper-clad steel grounding electrode has excellent electrical properties, and the excellent electrical conductivi...

AI Technical Summary

Problems solved by technology

However, the grounding electrode is a single body, not a combined grounding electrode, and has great defects in the free combination of lengths; in addition, the knocking end of the grounding electrode is as thick as the grounding rod, and the knocking area is small, which will cause installation problems. inconvenient
