Abstract
The utility model provides an integrally connecting expandable graphite nonmetal grounding device. The wire connecting end of the expandable graphite body is provided with a cuneate groove in which a metal block is inlaid, and the metal block is connected with a metal wire connecting post to compose the grounding device of the integrally connecting structure. Due to adopting the integrally connecting mode, the utility model reduces the resistance value of the connecting position to the lowest, raises the current diffusing rate of the current and ensures the safety of the grounding engineering, and after the grounding device is impacted by large current, the resistance value changes a little, and the utility model doesn't generate the embrittling and breaking phenomena, having good grounding effect and strong universality.
Description
Technical field
The utility model is to the improvement of the existing nonmetal earth electrode of graphite, especially provides a kind of whole interconnection system expanded graphite nonmetal earth electrode, belongs to engineering equipment ground connection electric installation technical field.
Background technology
In the nonmetal earth electrode of existing graphite, its metal connection post and expanded graphite body adopt thread connecting mode to be connected and fixed, because certainly leading to, both texture material differences, its connecting portion connect the space, therefore, earth electrode resistance increases, conductivity reduces, the electric current that directly the influences earth electrode flow rate of loosing, the critical grounding safety of engineering equipment, owing to the connecting portion intensity difference, also influenced the useful life of product in addition.
Summary of the invention
Shortcomings such as the utility model provides a kind of whole interconnection system expanded graphite nonmetal earth electrode, and the resistance that has solved existing thread connecting mode earth electrode is big, intensity is low.
Concrete solution of the present utility model is as follows: the terminals at the expanded graphite body have wedge-shaped slot, are inlaid with metal derby in the wedge-shaped slot, and metal derby and metal connection post connect and compose the earth electrode of whole syndeton.
The utility model is compared with the screw-type earth electrode, its good effect is: adopt the integral type connected mode, make the resistance value of connecting portion reduce to minimum, improve the diffusing flow rate of electric current, guaranteed the safety of earth work, behind the heavy current impact, change in resistance is little, acomia brittle failure is split phenomenon and is taken place, and ground connection is effective, highly versatile.
Description of drawings
Fig. 1 is the utility model structure principle chart.
Embodiment
According to shown in Figure 1, the wiring styletable of expanded graphite body 1 is provided with vee-cut 2, is cast with yellow gold metal derby 3 in the groove 2, and binding post 4 is planted in the earth electrode that constitutes whole connected mode in the metal derby 3.
Claims (1)
1, the nonmetal earth electrode of a kind of whole interconnection system expanded graphite, it is characterized in that: the terminals at the expanded graphite body have wedge-shaped slot, are inlaid with metal derby in the wedge-shaped slot, and metal derby and metal connection post connect and compose the earth electrode of whole syndeton.
