Anti-corrosion resistance-reducing lightning protection grounding device adopting multi-component alloy grounding body

Abstract

The invention relates to a device for power transmission and transformation, in particular to an anti-corrosion resistance-reducing lightning protection grounding device adopting a multi-component alloy grounding body. The anti-corrosion resistance-reducing lightning protection grounding device adopting the multi-element alloy grounding body is characterized in that a core body copper rod is arranged in the alloy grounding body in a casting mode, one end of the copper rod is connected with a cable, the copper rod is in brazing connection with the cable, the other end of the cable is connected with a steel plate, and the steel plate is connected with a grounding steel belt. The alloy grounding body is formed by casting multi-element metals including magnesium, manganese, zinc and aluminum and is embedded into an electrolyte material. The copper rod is processed through a silver process. The anti-corrosion resistance-reducing lightning protection grounding device has the advantages that a cathode protection principle is adopted, the copper rod is arranged in the multi-element alloy grounding body and processed through the silver process, the anti-corrosion resistance-reducing lightning protection grounding effect is good, lightning current produced under lightning overvoltage has good current drainage effect, and a protection function is complete. The service life can reach to 50 years.

Description

technical field [0001] The invention relates to a device for power transmission and transformation, and more specifically relates to a grounding device for power transmission and transformation. Background technique [0002] The construction of grounding grids for transmission lines, substations, and large-scale structures in power systems is very important. As the service life increases, the grounding impedance of the grounding grids also increases, which is likely to cause accidents. The geological conditions of different regions are different, and the soil conditions are different. In areas with high soil resistivity, the grounding network resistance of substations and transmission and distribution lines is qualified at the beginning of construction. Due to the change of resistance value and chemical corrosion, it may cause ACCIDENT. Using the principle of electrode resistance protection and using alloy grounding body castings, the effect has been significantly improved,...
