Abstract

The invention belongs to the technical field of distribution networks, particularly relates to a preparation method of an anticorrosion distribution network grounding device, and provides the preparation method of the anticorrosion distribution network grounding device. The buried grounding body is welded by using the E309-15 type alkaline welding rod. Resistance reduction of the buried grounding body is performed by using a resistance reducing agent, wherein the resistance reducing agent includes methyl benzotriazole. According to the preparation method of the anticorrosion distribution network grounding device, the technical problems that the existing grounding device has low service life and is liable to cause grounding hidden dangers can be solved.

Description

technical field [0001] The invention belongs to the technical field of distribution network, and in particular relates to a preparation method of an anti-corrosion distribution network grounding device. Background technique [0002] The grounding device is an important part of the grounding system. It can provide a leakage channel for fault current and lightning current, stabilize the potential, and provide a zero potential reference point to ensure the safe operation of the power system and electrical equipment. In actual production, the grounding device is placed underground or in a dark and humid environment for a long time, which is prone to corrosion and reduces the service life of the grounding device. For metals and metal oxides, according to their chemical properties, metals under acidic conditions are prone to ionization , react with hydrogen ions to generate free metal ions, and produce a galvanic reaction with negative ions in the environment, causing electrochemi...
