Embodiment 1

[0019] The diameter of the bottom plate is 2-20mm larger than the diameter of the bottom of the cement rod. The thickness of the bottom plate can meet the strength requirements, which is greater than the quality of the cement rod and the wire. The soil under the grounding plate device can meet the downward pressure requirements; one fixed element hoop is made of flat steel as a connection On the upper part of the chassis device, the fixed element hoop is evenly distributed with 4 tight top positioning bolts; several strips of flat steel are evenly welded with the bottom circular steel plate and the upper element hoop to form a grid-shaped squirrel-cage cylinder The surface of the body acts as a grounding electrode; the "grounding plate" is connected to the integrated grounding terminal of the cement pole through flat steel (or other metal materials) as the lead of the grounding plate to form a grounding device. This structure combines the functions of the chassis and the groundi...

Embodiment 2

[0024] Use 4mm steel plate to make a circular bottom plate with a diameter of 440mm, use 4*25mm flat steel to make a fixed hoop with a diameter of 440mm, use 4*25mm flat steel to make 6 support columns with a net height of 400mm, and the support columns are evenly distributed on the bottom plate The surroundings of the supporting column are fixed and connected by welding, and the other end of the support column is connected with the fixed hoop by welding to form a grounding plate device with a height of 400mm and a diameter of 440mm. The 4*16mm flat steel is used as the grounding plate lead wire, which is connected to the fixed element hoop, and the other end of the grounding plate lead wire is welded with a 4*40*100mm flat steel wire. The grounding plate lead wire here is used to guide lightning. A hole with a diameter of 17.5mm is opened at the top, and the fixed element hoop is connected with the integrated grounding terminal of the cement rod by full-thread M16*40 bolts or ...

Embodiment 3

[0036] Ground plate production plan

[0037] 1) Make a Φ440 round chassis (cylindrical bottom) with a 4mm thick steel plate.

[0038] 2) Use 4×25 flat steel to make 1 piece of Φ440 yuan hoop (upper part of the cylinder).

[0039] 3) Use 4×25 flat steel to make 6 pieces of flat steel (side of the cylinder) with a net height of 400 (excluding the edge 50).

[0040] 4) Weld the flanged part of the flat steel with the outer side of the round chassis according to 6 equal divisions (60°), and weld the other end of the flat steel with the outer side of the hoop to form a grounding plate with a height of 400 and an inner diameter of 440 (no need for plating zinc).

[0041] 5) Use a length of 4500, 4×16 flat steel as the lead wire of the grounding plate, and overlap it with the inner side of the hoop at the upper end of the grounding plate by electric welding (overlap length 40), so that the lead wire of the grounding plate is conveniently placed in the cylinder. The other end of th...

Abstract

The invention relates to a grounding disc device used for a concrete telegraph pole. The grounding disc device is constituted by a bottom plate, supporting columns disposed on the bottom plate, and fixed hoop connected with the top ends of the supporting columns. The grounding disc device is characterized in that the supporting columns are disposed on the periphery of the bottom plate, and the adjacent supporting columns are parallely arranged; the size of the bottom plate is cooperated with the size of the fixed hoop, and the fixed hoop is connected with a grounding disc lead. By adopting the grounding disc device, the damage on the road surface can be reduced, and the compensation costs can be greatly reduced. Under the same topographical and geological condition, the grounding resistance value of the grounding disc is lower than that of the grounding tube, and the low lightning current back flashover voltage can be reduced, and then the lightning resistant level of the line can be improved, and the power failure accident can be reduced. The construction operation intensity of the workers can be greatly reduced, and the construction quality can be guaranteed, and therefore the object of improving the working efficiency can be achieved.

Description

technical field [0001] The invention relates to the technical field of lightning protection for overhead lines and construction poles for cement poles, in particular to a "grounding plate" that integrates the functions of a cement pole anti-sinking round chassis and a grounding electrode, respectively replacing cement poles. Rod anti-sinking cement round chassis and lightning protection grounding pipe. Background technique [0002] At present, the 10kV distribution lines in the Shanghai area originally used bare wires, which will not cause disconnection accidents when struck by lightning. With the sharp increase in power consumption, a large number of 10kV lines have entered urban areas. In order to avoid accidents such as short circuits caused by falling objects from high altitudes. The 10kV distribution lines in Shanghai have fully promoted the application of insulated wires. In order to avoid disconnection accidents when insulated wires are struck by lightning, each ce...
