Abstract

The utility model relates to a grounding device for electric power construction and discloses a grounding rod. The grounding rod comprises an upper conductor, a steel core and a lower conductor; the upper conductor and the lower conductor are arranged at two ends of the steel core and are made of a copper material; nickel plated layers which are machined on the surfaces of the upper conductor and the lower conductor are an upper nickel plated layer and a lower nickel plated layer respectively; the thickness of the upper nickel plated layer and the lower nickel plated layer are 0.02mm; a connecting hole is machined on the upper conductor; a grounding hole is machined on the lower conductor; the outermost layer of the grounding rod of the utility model is an insulating sleeve; and two ends of the upper nickel plated layer and the lower nickel plated layer are exposed on the exterior of the insulating sleeve. According to the grounding rod of the utility model, a three-segment structure is adopted, the upper conductor and the lower conductor are plated with nickel respectively, and therefore, portions of the grounding rod, which are exposed on the exterior of the insulating sleeve, can be prevented from being oxidized and corroded; excellent conductive properties and favorable thermal stability of the upper conductor and the lower conductor can be given to full play; and at the same time, the steel core arranged at the middle can increase the strength of the grounding rod of the utility model; and only the two ends of the grounding rod are plated with nickel, and therefore, the grounding rod is more economical.

Description

A kind of earth rod
Technical field
The utility model relates to a kind of power construction earthing device, especially a kind of earth rod.
Background technology
As everyone knows, on the power consumption equipment of electric power system, usually to have earth rod to be connected with the zero line of power equipment, the lower end of earth rod be embedded in underground conductive contact and link together, with this, improve the fail safe of electricity consumption.Existing earth rod uses copper or iron material matter to be made more, and there is drawback in the earth rod of above two kinds of materials while using: although copper material earth rod good conductivity easily is corroded; Iron material matter earth rod intensity is low, poor electric conductivity, and long term exposure more easily is corroded out of doors, and useful life is shorter.
The utility model content
For overcoming the deficiencies in the prior art, it is a kind of reasonable in design, simple in structure, corrosion-resistant that the utility model provides, conduct electricity very well, and the earth rod of long service life.
For realizing above-mentioned technical purpose, the utility model adopts following scheme: a kind of earth rod, comprise upper conductor, steel core, lower conductor, it is characterized in that: upper conductor and lower conductor are positioned at the two ends of steel core, and its material is copper, upper conductor and lower conductor Surface Machining have nickel coating, are respectively nickel coating and lower nickel coating, and described upper nickel coating and lower nickel coating thickness are 0.02MM; On upper conductor, be processed with connecting hole, on lower conductor, be processed with ground hole; Outermost layer of the present utility model is insulating case, and the two ends of upper nickel coating and lower nickel coating are exposed in the insulating case outside.
The beneficial effects of the utility model are: the utility model has adopted three stage structure, after it has adopted the scheme of upper conductor and the nickel plating of lower conductor appearance, the exposed oxidation of earth rod in the insulating case outside, corrosion had both been avoided, the excellent conductive performance of upper conductor and lower conductor and thermal stability have preferably been given full play to again, simultaneously, middle steel core has improved again intensity of the present utility model, and only adopts the nickel plating of earth rod two ends more economical.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model top plan view.
In figure, 1, the copper core, 2, nickel coating, 2-1, upper nickel coating, 2-2, lower nickel coating, 3, upper conductor, 4, insulating case, 5, lower conductor, 6, ground hole, 7, connecting hole.
Embodiment
Shown in Fig. 1,2, a kind of earth rod, comprise upper conductor 3, steel core 1, lower conductor 5, upper conductor 3 and lower conductor 5 are positioned at the two ends of steel core 1, and the material of upper conductor 3 and lower conductor 5 is copper, upper conductor 3 and lower conductor 5 Surface Machining have nickel coating 2, are respectively nickel coating 2-1 and lower nickel coating 2-2, and described upper nickel coating 2-1 and lower nickel coating 22 thickness are 0.02MM; On upper conductor 3, be processed with connecting hole 7, on lower conductor 5, be processed with ground hole 6; Outermost layer of the present utility model is insulating case 4, and the two ends of upper nickel coating 2-1 and lower nickel coating 2-2 are exposed in insulating case 4 outsides.When the utility model used, the zero line of connecting hole 7 and external power equipment linked together, and the ground hole 6 of lower conductor 5 lower ends is connected and gets final product with underground conductive contact.

Claims (2)
