Embodiment 1

[0023] Such as figure 1 As shown, the present invention provides an absorbing grounding body, which includes a grounding body body 1 and a flexible graphite wire 2 arranged on the grounding body body 1 . The grounding body body 1 includes a shell 11 and a plurality of irregularly shaped flexible conductors 12 filled inside the shell 11. The shell 11 is a conductor or a semiconductor, and its structure is a cylinder or a cuboid with a cavity formed inside, and the shell 11 The two ends are open, and the two open ends of the shell 11 are equipped with detachable plugging ends 4 for the flexible graphite wire 2 to pass through. The conductor 12 is not easy to leak, and the flexible conductor 12 is expanded graphite particles or conductive sponges or other non-metallic conductive particles. Expanded graphite or conductive sponges are like cotton and have certain elasticity. Interaction between expanded graphite or conductive sponges Under the elastic buffer, it can absorb the imp...

Embodiment 2

[0025] The difference from Embodiment 1 is that a plurality of water-absorbing resins 3 for reducing the grounding resistance are distributed among the multiple flexible conductors 12 in the grounding body 1, and the water-absorbing resin 3 can keep the surroundings of the grounding body in a wet state all the time , which is conducive to improving the grounding resistance conditions of the surrounding soil, reducing the grounding resistance of the grounding system, and improving the grounding performance of the grounding body.

[0026] In the absorbing grounding body of the present invention, flexible graphite wires 2 are arranged on the grounding body body 1, and a plurality of irregularly shaped flexible conductors 12 are filled inside the grounding body body 1. Regular flexible conductors 12, when the lightning current discharges to the ground through irregular flexible conductors 12, forces in irregular directions will be generated between the flexible conductors 12, and f...

Abstract

An absorption type grounding body is disclosed, comprising a grounding body and a flexible graphite wire arranged on the grounding body, the grounding body includes a housing and a plurality of irregularly shaped flexible conductors filled in the housing, the flexible graphite wire passes through the grounding body, and one end of the flexible graphite wire passes through the housing of the grounding body for connecting the grounding device, the other end penetrates out of the housing of the grounding body for connection to the depth of the soil, the flexible conductor is expanded graphite particles or conductive sponge, and a plurality of water-absorbent resins for reducing the grounding resistance are distributed between the plurality of flexible conductors in the grounding body. The absorption type grounding body of the invention fills the housing of the grounding body with irregular flexible conductors, generates irregular direction force when lightning energy passes between the flexible conductors, and can cancel and digest lightning strike energy mutually, does not need complex connection lines, and has the advantages of simple structure, good grounding effect, small volume and convenient use.

Description

technical field [0001] The invention relates to the technical field of lightning protection and grounding of electric power systems, in particular to an absorbing grounding body. Background technique [0002] The grounding device of the transmission line is the basic guarantee and important measure to maintain the safe and reliable operation of the power system and ensure the safety of electrical equipment and operating personnel. The underground plays the role of lightning protection, providing effective protection for transmission lines, so as to avoid power outages caused by lightning strikes, which is of great significance to the safe operation of the power system and the reliability of power supply. [0003] At present, some geographical environments have undulating mountains, high altitude, and complex terrain. Most of these mountainous areas belong to areas with high soil resistivity. It is difficult for the grounding resistance of transmission line towers to meet the...
