Embodiment 1

[0036] Such as Figure 1-4As shown, the present embodiment provides a deep vertical fast-installed graphite grounding electrode, which includes several sections of copper rods 1 and graphite braided layers 2 tightly covering the outside of the red copper rods 1, and the periphery of the red copper rods 1 and the graphite braided layer 2 passes through several The stainless steel casing 3 is fastened, and both ends of the copper rod 1 are provided with external threads 11, the external threads 11 at one end of the copper rod 1 are threaded to be connected with the cone head 4, and the external threads 11 at the other end are threaded through the connector 5 to have a tail end seal Bolt 6;

[0037] Among them, the red copper rod 1 is obtained by electroplating or cold-rolling a layer of red copper on the outer layer of the high-strength carbon steel substrate, which improves the corrosion resistance of the high-strength carbon steel substrate; 32mm; the inner cavity of the cone...

Embodiment 2

[0044] Such as figure 1 , Figure 5 As shown, this embodiment provides an integrated conveying, cutting, and crimping device for the conveying, cutting, and crimping procedures of the deep vertical fast-loading graphite grounding electrode, specifically when the deep vertical fast-packing graphite grounding electrode meets When there are hard objects such as rocks and large stones in the deep underground, and the vertical installation cannot be continued, cut it off at a length 200mm above the ground, and use a stainless steel sleeve 3 with a length of 100-120mm to weave a 50mm long copper rod 1 and graphite Layer 2 is crimped, and the remaining 50-60mm stainless steel sleeve 3 is not crimped, and the uncrimped stainless steel sleeve 3 is partially crimped with the above-mentioned truncated copper rod 1 and graphite braided layer 2, so that the graphite grounding electrode completes the deep vertical fast It improves the overall processing and installation efficiency.

Abstract

The invention discloses a deep vertical fast-assembly graphite grounding electrode and a processing technology thereof, and relates to the technical field of fast-assembly grounding electrodes, the graphite grounding electrode comprises a plurality of sections of red copper rods and a graphite braid layer tightly covering the red copper rods, and the peripheries of the red copper rods and the graphite braid layer are fastened through a plurality of stainless steel sleeves. The external thread at one end of the red copper rod is in threaded connection with a conical head, and the external thread at the other end of the red copper rod is in threaded connection with a tail end sealing bolt through a connector; the graphite grounding electrode has good conductivity, the through-flow performance of the grounding electrode is improved, and electrochemical corrosion is slowed down; the graphite braid layer has high specific surface area and flexibility, so that the graphite braid layer can be better attached to soil, and the contact resistance between the grounding electrode and the soil is reduced; and in the machining process, an integrated conveying, cutting and crimping device is adopted to automatically complete conveying, cutting and crimping procedures, so that the machining and mounting efficiency of the graphite grounding electrode is greatly improved.

Description

technical field [0001] The invention relates to the technical field of quick-installation grounding electrodes, in particular to a deep vertical quick-installation graphite grounding electrode and a processing technology thereof. Background technique [0002] The grounding device in the power system is very important. Nowadays, most of the grounding devices are metal or non-metallic grounding materials. The grounding body is generally laid by the base frame of the tower and the extension line. The number of uses is large, the area is large, and the construction is difficult. Generally, after 3 to 7 years of operation of the grounding device, it is found that the grounding body is severely corroded, resulting in a sharp increase in grounding resistance, and a significant increase in the probability of lightning tripping; [0003] Although the graphite-based flexible non-metallic grounding material has good corrosion resistance and excellent resistance reduction, its own resis...
