Abstract
Provided is an anticorrosion lightning protection resistance-reducing earthing device, used for overcoming the defects of the conventional earthing device having poor anticorrosion performance and large resistance. The anticorrosion lightning protection resistance-reducing earthing device is characterized in that: a conductive housing (1) is internally provided with a plurality of metal cores (3); and the exterior (3) of the metal core (3) is provided with a coating layer (2). The anticorrosion lightning protection resistance-reducing earthing device features excellent corrosion resisting performance and small resistance.
Description
Technical field
The utility model relates to a kind of earthing device, a kind of specifically anticorrosion lightning protection electric resistance reducing grounding device.
Background technology
At present usually with the naked copper material as earthing conductor, the formation electrode is installed in the ground as the naked copper material of earthing conductor.But the earthing device of naked copper material is perishable owing to the moisture in the soil, the acidic materials of soil etc. act on, and has so both shortened the useful life of earthing device, has increased the resistance of earthing device again, makes its poor electric conductivity, and ground connection is unreliable.
Summary of the invention
In order to overcome the problem that existing earthing device is not corrosion-resistant and resistance is big, the utility model provides a kind of anticorrosion lightning protection electric resistance reducing grounding device, and this anticorrosion lightning protection electric resistance reducing grounding device has the characteristics corrosion-resistant, that resistance is little.
The technical scheme of the utility model is: a kind of anticorrosion lightning protection electric resistance reducing grounding device, comprise external conductive casing, and described external conductive casing inside is provided with equably that several are metal-cored, and described metal-cored outside is provided with coating.
The utlity model has following beneficial effect: owing to take such scheme, external conductive casing and metal-cored all can conduct electricity, and external conductive casing can reduce resistance, makes conductive effect better; And metal-cored coating exterior has increased the decay resistance of this earthing device, can prevent that the conducting metal solid wire from interrupting, and increased the reliability of earthing device.
Description of drawings:
Fig. 1 is the structural representation of the utility model cross section.
1-external conductive casing among the figure, the 2-coating, 3-is metal-cored.
Embodiment:
Below in conjunction with accompanying drawing the utility model is described further:
By shown in Figure 1, a kind of anticorrosion lightning protection electric resistance reducing grounding device comprises external conductive casing 1; Described external conductive casing 1 is made up of electroconductive resin, and external conductive casing 1 inside is provided with equably that several are metal-cored 3, and metal-cored 3 material can be a copper; Its quantity can be 3-9, and described metal-cored 3 outsides are provided with coating 2, and coating 2 also is a kind of electric conducting material; Make metal-cored 3 and external conductive casing 1 between the conduction, coating 2 has corrosion resistant performance simultaneously.The resistance of the external conductive casing 1 of this earthing device is little, make conductive effect better, and metal-cored coating exterior 2 has increased the decay resistance of this earthing device, has increased the reliability of earthing device.
Claims (1)
1. an anticorrosion lightning protection electric resistance reducing grounding device comprises external conductive casing (1), it is characterized in that: described external conductive casing (1) inside is provided with several metal-cored (3) equably, and described metal-cored (3) outside is provided with coating (2).
