Description
Technical Field
The utility model belongs to the technical field of the graphite grounding body, concretely relates to flexible compound graphite grounding body.
Background
The graphite grounding wire is widely applied as a novel resistance reducing material, but the common graphite wire in the current market has high self-contact resistance and low tensile strength due to loose self-structure, so that the graphite grounding wire can only be used on the transmission and distribution circuit grounding. The graphite wire produced by the traditional process is mostly composed of two parts: inside utilizes many single-stranded graphite single lines as the filler, and what adjusts is how much by the radical that fills single-stranded graphite line to the size of graphite line diameter, and outside is tightly worked out around inside many graphite lines by single graphite single line of stranded through special establishment equipment. Through the measurement of various graphite grounding wires produced in the market, the following results are found: the surface contact resistance is generally high (at least up to around 2 ohms) and the ohmic value increases with increasing distance from the measuring point (up to 15 ohms). Because the contact resistance of the traditional graphite wire is high, the region with lower grounding resistance requirement basically does not adopt the graphite wire as a resistance reducing material. Therefore, it is necessary to design a flexible composite graphite grounding body with low resistance and high tensile strength.
SUMMERY OF THE UTILITY MODEL
Aiming at the defects in the prior art, the utility model aims to provide a flexible composite graphite grounding wire which adopts copper wires for the external weaving part and has ultra-low contact resistance by utilizing the principles of high conductivity and small contact resistance of copper; the inside is through the winding increase stainless steel strand wires, improves the flexible compound graphite grounding body of the tensile strength of graphite line.
The utility model relates to a flexible compound graphite grounding body is realized through following technical scheme including the utmost point core, centers on the utmost point core lays the inside obturator, the outside body of weaving of inside obturator external connection, the utmost point core adopts phi 5 mm's 316 stainless steel strand wires, the outside body of weaving is woven by graphite strand wires and red copper flexible wire strand wires and is constituteed.
Further, the outer braid is composed of 32 sets of graphite strands braided with 4 sets of copper soft strands.
Further, the outer braided body is formed by braiding 36 groups of graphite strands and 8 groups of red copper soft strands.
Furthermore, the internal filling body is composed of a plurality of graphite wire monofilaments.
The beneficial effects of the utility model reside in that: simple structure, reasonable in design is showing improvement ground connection efficiency, reduces contact resistance, increases tensile strength's flexible composite graphite grounding body. The grounding conductor has good contact effect with the ground, short current discharge time, good corrosion resistance and low resistance, can expand the application range, and can be widely applied to different grounding projects.
