Description
Technical Field
A multi-application mortise and tenon type spacing device for a tower grounding grid belongs to the field of construction of power system transmission line tower grounding grids.
Background
A power transmission line tower grounding grid of a power system is a basic power facility for protecting a power transmission line from lightning damage, and the grounding characteristic of the grounding grid is an important influence factor for preventing overvoltage at the tower top and insulator flashover. The existing tower grounding grid usually adopts steel metal grounding materials such as carbon steel or galvanized round steel, and the grounding materials are easy to corrode and break when buried in the ground, so that the tower grounding grid begins to adopt a nonmetal conductive material such as a flexible graphite composite grounding material as a grounding body in recent years. The flexible graphite composite grounding material is usually required to be buried in a line tower which is put into operation during grounding construction, although the original zinc-plated steel grounding net of the line tower is corroded to different degrees, most zinc-plated steel grounding bodies do not achieve corrosion fracture, and the current dispersion effect can still be continuously exerted. Therefore, in order to reduce resource waste, a general treatment method is to lay the flexible graphite composite grounding material on the basis of keeping the original galvanized steel grounding grid, so that the grounding body made of two materials forms the multi-material combined grounding grid.
In practice, when a grounding grid of a transmission line tower is grounded by adopting various grounding materials, the problem of intervals among different grounding materials is often faced. On one hand, if the graphite embedded in the grounding trench in parallel contacts with the steel grounding body, backflow is easily formed between the two grounding bodies after the contact, and the overall current dispersion effect of the tower grounding network is affected. On the other hand, when two kinds of ground contact bodies overlap each other at the intersection, contact in the vertical direction is likely to occur at the intersection. Site constructors often adopt objects such as stones, branches and soil to isolate different grounding materials temporarily, but the reliability of the mode is poor, the distance is not easy to control, and two grounding bodies are easy to loose and contact. Although there are some spacers that can realize the spacing of the grounding materials at present, and fasteners such as bolts are usually purchased for fastening, since the spacing of the grounding materials needs to be realized, the spacers cannot be realized by using any metal material, so that the conventional fasteners are seriously worn and have poor reliability in the use process, and when the conventional fasteners are realized by using various new materials which are made of non-metal materials and are wear-resistant, the production cost of the spacers is often greatly increased.
