Abstract
The utility model discloses a grounding device, which mainly solves the problems in the prior art that the cost is high, the service life is short, and the adaptability to various soils is poor. The grounding device of the utility model comprises a grounding rod, a conducting cable and a connecting part used for fixing the conducting cable on the grounding rod, wherein the grounding rod comprises a rod core and an outer coating layer, the rod core is made of low carbon steel, the outer coating layer is made of copper, lead, aluminum, copper alloy, aluminum alloy or copper-aluminium alloy, and the thickness of the outer coating layer is not less than 0.5 millimeters. Because the outer coating layer is made of copper, lead, aluminum, copper alloy, aluminum alloy or copper-aluminium alloy, the cost of the grounding device is lower than the cost of the grounding device made of pour copper, the cost is temperate, the copper, lead, aluminum, copper alloy, aluminum alloy or copper-aluminium alloy of the outer coating layer have high corrosion proof capability, the service life is prolonged, and the device can be suitable for various soils.
Description
Technical field
The utility model relates to a kind of earthing device.
Background technology
Be the damage of avoiding being struck by lightning, electric equipment and operating personnel's safety often will be used to play the earthing device of leading, let out the lightning current effect in guarantee transmission line and the power station; Domestic a large amount of uses now be that steel pipe, round steel and the band steel made of mild steel are as earthing device, the earthing device cost of manufacture of this structure is low, technology is simple, but chemical corrosion and electrochemical corrosion can take place in mild steel in soil, and very fast of its corrosion rate, the life cycle of earthing device is very short, and the cost of maintaining is high; At present, on market, occurred a kind of with through the steel of heat dip zinc treating earthing device as manufacturing materials, its corrosion resistant ability is higher than original earthing device, but this earthing device can only adapt to the neutral soil that water content is low, resistance is low, in high and the acid or alkaline soil of water content height, resistance, its corrosion rate still is difficult to control, and have only about 3-5 general useful life, still is difficult to satisfy user's requirement; The earthing device that uses copper to make as raw material good conductivity and long life-span are arranged, but it is with high costs, can not adapt to the extensive requirement of using in market.
Summary of the invention
The purpose of this utility model is to provide a kind of earthing device, and cost is moderate, and the life-span is longer, and is stronger to the adaptability of various soil.
A kind of earthing device described in the utility model, contain earth rod, cable and cable is fixed on connector on the earth rod, earth rod contains excellent core and surrounding layer, the rod core is made by mild steel, surrounding layer is copper, lead, aluminium, copper alloy, aluminium alloy or albronze, and the thickness of surrounding layer is not less than 0.5 millimeter.
Because a kind of earthing device described in the utility model, the rod core is made by mild steel, surrounding layer is copper, lead, aluminium, copper alloy, aluminium alloy or albronze, the earthing device that its cost is compared the fine copper making is cheap a lot, cost is moderate, and after the earthing device of selecting for use different materials to make according to operating position inserted in the soil, the copper of surrounding layer, lead, aluminium, copper alloy, aluminium alloy or albronze had stronger corrosion resistance, prolong useful life, can adapt to various soil.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail:
Fig. 1 is a schematic diagram of the present utility model;
Fig. 2 is a cutaway view of the present utility model.
Embodiment
A kind of earthing device described in the utility model, contain earth rod 1, cable 2 and cable 2 is fixed on connector 3 on the earth rod, earth rod 1 contains excellent core 4 and surrounding layer 5, rod core 4 is made by mild steel, surrounding layer 5 is copper, lead, aluminium, copper alloy, aluminium alloy or albronze, the thickness of surrounding layer 5 is not less than 0.5 millimeter, and surrounding layer 5 can use mode such as plating to form one deck coating outside excellent core 4, or uses the method for mechanical compaction.
