Problems solved by technology

However, the design life of general substations is based on 25-30 years. The actual safe life of grounding does not match the design life of substations. In addition, the increase in system capacity and the increase in short-circuit current will make the grounding grid after corrosion even worse. Cannot meet the requirements of safe operation
Although copper is a good grounding conductive material with strong soil corrosion resistance and can meet the requirements of 25-30 years, copper is a heavy metal and is easy to pollute the soil; and the price of copper grounding is 5-6 times that of galvanized steel or iron. For this reason, the industry hopes that there will be cheaper and better grounding materials

Embodiment 1

[0033] please see figure 1 and Figure 4 , a grounding wire for a circular foundation, characterized in that it is composed of a first connecting section 1, a second connecting section 2, and a third connecting section 3; the first connecting section, the second connecting section, the third All three connecting sections are in the shape of a cuboid, the other end of the first connecting section is connected to one end of the second connecting section, the other end of the second connecting section is connected to one end of the third connecting section, and the right plane of the first connecting section is located at the third connecting section On the left side of the left plane of the segment, the first connecting segment, the second connecting segment, and the third connecting segment have equal thickness and equal width, and the first connecting segment, the second connecting segment, and the third connecting segment are three One-piece structure and the same material, ...

Embodiment 2

[0035] please see figure 2 and Figure 4 , a grounding wire for a circular foundation, characterized in that it is composed of a first connecting section 1, a second connecting section 2, and a third connecting section 3; the first connecting section, the second connecting section, the third All three connecting sections are in the shape of a cuboid, the other end of the first connecting section is connected to one end of the second connecting section, the other end of the second connecting section is connected to one end of the third connecting section, and the right plane of the first connecting section is located at the third connecting section On the left side of the left plane of the segment, the first connecting segment, the second connecting segment, and the third connecting segment have equal thickness and equal width, and the first connecting segment, the second connecting segment, and the third connecting segment are three One-piece structure and the same material,...

Embodiment 3

[0037] please see image 3 and Figure 4 , a grounding wire for a circular foundation, basically the same as the implementation example 1 or implementation example 2, the difference is that: the first connecting section 1 and the second connecting section 2 pass through a circular arc-shaped first transition section 12 The connection between the second connecting section 2 and the third connecting section 3 is connected by an arc-shaped second transition section 23 . This connection allows the stress build-up in the ground wire to be more distributed in use.

[0038] A grounding wire for a circular foundation described in any of the above implementation examples is characterized in that: the width of the first connecting section is 5mm-50mm.

[0039] A grounding wire for a circular foundation described in any of the above implementation examples is characterized in that: the thickness of the first connecting section is 2mm-10mm.

Abstract

The invention relates to the technical field of electric power, in particular to an electric power tower employing a circular foundation ground wire. The electric power tower comprises an electric power tower body and the circular foundation ground wire; the electric power tower is characterized in that a grounding connection body is fixed on the outer surface of the lower part of the electric power tower body; a grounding gap is formed between the grounding connection body and the electric power tower body; the circular foundation ground wire has a special structure; a fixing component fixes a first connection segment and the grounding connection body into a whole; and the electric power tower body, the grounding connection body, the fixing component and the circular foundation ground wire all are electric conductors. The ground wire provided by the invention has the beneficial technical effects of being beautiful, easy to manufacture, more convenient to construct, more reliable in grounding and the like.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a grounding wire for a circular foundation and a power tower using the grounding wire for the circular foundation. Background technique [0002] In power grid engineering, grounding is an electrical safety measure taken to ensure the normal operation of electrical equipment and personal safety. It is realized by connecting with the grounding device. Commonly used are protective grounding, working grounding, anti-static grounding, and lightning protection grounding. Wait. The grounding device introduces the leakage current, static current, and lightning current that may be generated on the electrical equipment into the ground, so as to avoid personal electric shock and possible fire, explosion and other accidents. Therefore, the requirements for equipment grounding are getting higher and higher, not only in terms of safety, but also in terms of aesthetics, which increases...
