Description

Technical Field

[0001] The present invention relates to the technical field of power accessories, and in particular to a grounding capacity expansion and discharge device. Background Art

[0002] The grounding device is a general term for the grounding body and the grounding wire. Its function is to conduct lightning current into the ground. The grounding body is a metal conductor or a group of conductors that are in direct contact with the soil. It is divided into artificial grounding bodies and natural grounding bodies. The grounding body is a conductor that is in close contact with the earth's soil and provides an electrical connection with the earth, safely dissipating the lightning energy and allowing it to be discharged into the earth.

[0003] At present, most transmission lines use single-material grounding bodies such as metal or non-metal. Metal grounding bodies include galvanized round steel, and non-metal grounding bodies include graphite lightning protection grounding bodies. After the grounding body is connected from the pole tower into the soil, the grounding resistance of the pole tower is reduced through the contact between the grounding body and the soil. When the pole tower is struck by lightning, the lightning current is introduced into the grounding body along the pole tower and discharged into the earth through the grounding body, thereby achieving the effect of lightning protection and current discharge. However, when the resistivity of the soil is high, or the contact between the soil and the grounding body is insufficient during the dry season, and the contact resistance is large, if the lightning current cannot be discharged into the earth in time, it will cause the lightning current to counterattack along the grounding body to the wire at the top of the pole tower, causing a tripping and power outage accident, seriously affecting the safe operation of the transmission line, and causing huge economic losses. Summary of the invention

[0021] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] like Figure 1 and Figure 2 As shown together, a grounding capacity expansion leakage device includes a body converging body 1 and a leakage body 2 connected together, the body converging body 1 includes a body converging body shell and a conductive capacity expansion filler 3 filled in the body converging body shell, the leakage body 2 includes a leakage body shell and a conductive capacity expansion filler 3 filled in the leakage body shell, the body converging body 1 is provided with a bus conductor 4 connected to the grounding conductor, the leakage body 2 is provided with a grounded leakage conductor 5, and the bus conductor 4 and the leakage conductor 5 are respectively located at opposite ends of the grounding capacity expansion leakage device.

[0023] like Figure 1 and Figure 2 As shown together, in this embodiment, the body shell of the flow collector and the body shell of the flow drain are integrated, and the inner cavity of the body shell of the flow collector is connected to the inner cavity of the body shell of the flow drain. With such a structure, the volume of the grounding expansion flow drain device is increased, and the power collection capacity of the grounding expansion flow drain device is improved.

[0024] like Figure 1 and Figure 2 As shown together, in this embodiment, the bus conductor 4 is connected to the leakage conductor 5. In this embodiment, the bus conductor 4 and the leakage conductor 5 are preferably overlapped and bundled together by overlapping method. Such a structure improves the stability of the connection between the bus conductor 4 and the leakage conductor 5.

[0025] like Figure 1 and Figure 2 As shown in the figure, because graphite has good electrical conductivity, plasticity and thermal shock resistance, the graphite lightning protection grounding wire has good electrical conductivity, so in this embodiment, the bus conductor 4 and the leakage conductor 5 are preferably graphite lightning protection grounding wires. In practical applications, the bus conductor 4 and the leakage conductor 5 can also be made of other materials with strong electrical conductivity, which will not be described in detail here.

[0026] like Figure 1 and Figure 2 As shown together, in this embodiment, the sink housing is preferably a metal housing or a graphite-based composite housing, and the drain housing is preferably a metal housing or a graphite-based composite housing. The use of a metal housing or a graphite-based composite housing increases the contact area with the soil and improves the grounding leakage effect.

[0027] like Figure 1 and Figure 2 As shown together, the conductive expansion filler 3 in this embodiment includes a high-carbon graphite mixture, an inorganic conductive ion glue and nickel powder, the weight percentage content of the high-carbon graphite mixture is 75% to 83%, the weight percentage content of the inorganic conductive ion glue is 12% to 17%, and the weight percentage content of the nickel powder is 5% to 8%. In this embodiment, the high-carbon graphite mixture preferably includes high-carbon graphite worms and high-carbon graphite powder, the weight percentage content of the high-carbon graphite worms is 30% to 40%, and the weight percentage content of the high-carbon graphite powder is 60% to 70%.

[0028] like Figure 1 and Figure 2 As shown together, the leakage body 2 in this embodiment is symmetrically arranged on the side of the body 1, the bus conductor 4 is arranged at the end of the body 1, and the leakage conductor 5 is arranged at the end of the leakage body 2 away from the bus conductor 4. The use of such a symmetrical structure can make the leakage of the grounding expansion leakage device of the present invention more stable. In practical applications, a plurality of leakage bodies 2 can be provided according to needs, and a plurality of leakage bodies 2 can be evenly arranged on the periphery of the body 1, so that the leakage conductors 5 of the leakage bodies 2 are laid in multiple directions, so that the lightning current or the induced current is dispersed to different directions and discharged into the earth, thereby further improving the leakage capacity of the grounding expansion leakage device of the present invention.

[0029] like Figure 1 and Figure 2 As shown together, the cross-section of the concentrator 1 and the drain body 2 is square or circular. In this embodiment, the cross-section of the concentrator 1 and the drain body 2 is preferably square. In actual applications, the cross-section of the concentrator 1 and the drain body 2 can also be long, triangular or diamond, which is not limited in this embodiment.

[0030] The grounding capacity expansion leakage device provided by the present invention utilizes the principle of current collection and discharge of a capacitor to quickly and temporarily store the lightning current or induced current introduced into the grounding body in the body concentrator 1. The body concentrator 1 diffuses the lightning current or induced current into the leakage body 2, and discharges the lightning current or induced current into the earth through the leakage conductor 5 of the leakage body 2, thereby solving the problem that a grounding body made of a single material cannot collect electricity in the prior art, and improving the leakage capacity of the grounding capacity expansion leakage device of the present invention. Since the leakage body 2 is connected to the body concentrator 1, the contact area between the entire device and the soil is increased, so that the lightning current or induced current is discharged into the earth more quickly after being gathered, thereby solving the problem of insufficient leakage capacity caused by the small contact area with the soil in the prior art, improving the grounding leakage effect, ensuring the safe operation of the transmission line, and reducing economic losses.

[0031] The present invention is not limited to the above-mentioned specific implementation modes. Various changes made by ordinary technicians in this field based on the above-mentioned concepts without creative labor are all within the protection scope of the present invention.
