Abstract
The utility model belongs to the technical field of an earthing down lead of a transmission line, relating to a sawing-proof earthing down lead. The characteristic is that the surface of every component of the existing earthing down lead is annealed and is coated with rust-preventive material. The performance of oxidation resistance, rust-preventing and breaking resistance is hugely enhanced in condition that the electrical resistivity isn't increased. Thus, the utility model can better prevent the lightning disturbance hidden danger to the electric equipment because the earthing down lead is mangled.
Description
Technical field:
The utility model belongs to transmission line down conductor technical field, relates to the antirust down conductor of a kind of anti-saw.
Background technology:
The down conductor of existing transmission line is made up of gusset piece and downlead, adopts round steel, the band iron of common iron to make, not only easily oxidation corrosion but also easily by sawed-off, in case be damaged, power consumption equipment very easily suffers lightning hazards, cause economic loss to the user, suddenly special procure and to solve.
Summary of the invention:
The designer studies by analysis, and purpose is to design the anti-saw of a kind of energy corrosion-resistant down conductor.
The technical measures that the utility model is taked are that the down conductor to existing transmission line is improved, and on the gusset piece and downlead structure of existing down conductor, increase anti-saw layer and antirust coat, promptly constitute the antirust down conductor of a kind of anti-saw.Described anti-saw layer is after the surface of downlead and gusset piece is heat-treated respectively, at the higher anti-saw layer of the hardness intensity of above-mentioned two plate surface; Described antirust coat is that plating is coated with the antirust coat that rush-resisting material forms outside described anti-saw layer.
This anti-saw down conductor of the present utility model, compare with existing down conductor, owing to increased antirust coat and anti-saw layer, thereby greatly improved the performance of anti-oxidant anti-corrosion and anti-destruction, have the corrosion of being difficult for, be difficult for, be not afraid of collision and knock advantages such as prolongation in useful life by sawed-off, its resistivity is not higher than the resistivity of existing down conductor, thereby prevents the damage to crops caused by thunder hidden danger that suffers damage and cause to power consumption equipment because of down conductor preferably.
Description of drawings:
Fig. 1 represents the structural representation of the anti-saw of the utility model down conductor.
Embodiment:
Referring to Fig. 1 also in conjunction with the embodiments, architectural feature of the present utility model, performance and advantage will be clearer.
The example structure of the anti-saw of the utility model down conductor comprises: gusset piece 1, downlead 2, and anti-saw that increases at above-mentioned two parts surfaces layers 3 and antirust coat 4.Wherein, described anti-saw layer 3 is anti-saw layers that the hardness intensity that the surface of above-mentioned two parts carries out forming on the surface after the conventional heat treatment is improved: described antirust coat 4 is the anti-oxidant rust stable antirust coats that form in above-mentioned anti-saw layer external galvanized layer japanning.
After installing and using, the anti-saw of the utility model down conductor is not afraid of oxidation corrosion, be not afraid of collision and knock, when by sawing saw blade easily skid easy to wear, thereby ensured that power consumption equipment ground connection is good, reduced the damage to crops caused by thunder rate of failure.
Claims (1)
1, a kind of anti-saw down conductor has gusset piece, and downlead is characterized in that also increasing on the surface of gusset piece and downlead anti-saw layer and antirust coat are arranged, to improve vandal-proof hardness intensity of two parts and anti-oxidant anti-corrosion performance.
