Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0023] Such as Figure 1 ~ Figure 2 As shown, a high-frequency interference protection grounding electrode includes multiple grounding rods 4. The grounding rods 4 are preferably five copper rods with a diameter of 10mm and a length of 10m. The five grounding rods are distributed in an arc and are inclined outward relative to the plumb line. Set in the soil at a certain angle, the inclination angle of the ground rod 4 is 10-20 degrees, preferably 15 degrees, the top of the ground rod 4 is at least 0.6m from the ground surface, and the distance between any two ground rods is greater than or equal to...

Abstract

The invention discloses a high-frequency interference protection grounding electrode which comprises a plurality of grounding rods, the grounding rods are distributed in an arc shape, are inclined outwards by a certain angle relative to the plumb line, and are arranged in the soil, the distance between any two grounding rods is larger than or equal to the sum of the lengths of the two grounding rods, slurry of which the electrical resistivity is lower than that of the soil is filled between the grounding rods and the soil, and the grounding rods are connected into a whole through connecting copper bars. The invention further discloses a corresponding laying method. Through the adoption of the manner of inclined inserting and deep laying of the grounding bars and the use of the method of slurry filling, the number of the grounding rods decreases, the occupied area is small, and the large-area earth excavation construction is avoided.

Description

technical field [0001] The invention belongs to the technical field of engineering electrical grounding installation, and in particular relates to a high-frequency interference protection grounding electrode and an embedding method thereof. Background technique [0002] In areas with limited geological environment conditions, for example, there is no long-distance soil for excavation on the construction site, high-frequency interference protection grounding is an important construction technology, and the interference signals generated by high-frequency equipment often affect other electrical systems due to grounding construction quality problems The stability of operation is seriously affected. In the electrical construction site, it is easiest to implement vertical grounding for high-frequency interference protection grounding, but there are many grounding poles, correspondingly many high-frequency interference points on the upper end of the grounding body, and the floor s...
