Embodiment
Embodiment
The utility model is combined high-voltage grounding wire, comprises earth electrode 2, ground connection annealed copper wire, clamp 8, earth connection line card 11 form.The contact situation different according to required grounding apparatus end, can use the earth connection line card 11 of clamp 8 or steel to connect respectively.
The earth electrode 2 that zinc covers Steel material be with special steel and zinc for primary raw material, form double metallic composite material by special process.This product combines the advantage of zinc band anode and traditional galvanized steel material; both there is the high strength of steel, higher thermal stability; there is again the function of cathodic protection; contact resistance is less than 0.5 Ω; and than ground connection and cathodic protection separate do more scientific, more economical, service life is longer, the life-span generally can reach more than 5 years.Earth connection comprises earth bus 4 and ground connection separated time, employing multiply high-quality annealed copper wire is stranded to be formed, and covers softness, resistant to elevated temperatures transparent insulation sheath outward, can prevent the wearing and tearing to ground connection copper cash in using, copper cash reaches fatigue strength testing requirement, guarantees the safety that operating personnel is in operation.This device is the important tool in order to ensure staff when unexpectedly there is voltage on the equipment had a power failure and circuit.By regulation, earth connection must be 25mm
2above naked copper flexible cord is made.
Earth electrode 2 is " T " font, and top is with mounting panel 1, and described earth electrode 2 end is with ground connection point 5, and the tapering of ground connection point 5 is 1:3-5, with anti-slip veins on mounting panel 1.For the earth point being difficult to insert, mounting panel 1 can be struck with hammer, knock in ground connection ground.
Earth electrode 2 is connected with earth bus 4, and earth bus 4 separates at least two ground connection separated times, and ground connection separated time end is connected with clamp 8 or earth connection line card 11, and earth connection line card 11 is U-type groove structure.Clamp 8 is common metal pincers.The side plate of earth connection line card 11 is installed fastening screw screw mandrel 10, fastening screw screw mandrel 10 end is flexibly connected with clamping plate 9, and fastening screw screw mandrel 10 is with "T"-shaped handle.As shown in Figure 1, rotary handle, clamping plate 9 non rotating only can move up and down, for apparatus for fastening.
Earth bus 4, ground connection separated time are inner is greater than 25mm for area of section
2copper wire, earth bus 4, ground connection separated time are connected with earth electrode 2 by copper lug 3, and ground connection separated time is connected with clamp 8 or earth connection line card 11 by copper lug 3.Ground connection separated time connects at least one clamp 8, at least one earth connection line card 11.To the thin sheet form earth terminal being easy to wear equipment, steel earth connection line card 11 is adopted to connect; Be not suitable for using the equipment of steel earth connection line card to adopt clamp 8 to connect to wear-resisting undermining.
Operating procedure is as follows:
Earth connection is connect earth electrode 2 by the copper lug 3 of eyes, earth connection separated time is fixed on earth connection line card 11 or clamp 8 by the copper lug 3 of eyes, form the earth connection of complete set.
Before using earth connection, first electrical verification should confirm to have a power failure, carry out after equipment confirms no-voltage.First clamp 8 or earth connection line card 11 are connected on ground network or band iron part, then with ground operation bar, another conductor wire end (earth connection line card 11 or clamp 8) are fastened on equipment.When removing short-circuit grounding wire, order is just in time contrary to the above.
The short-circuit grounding wire of installing, the distance of it and charging equipment, consider the impact of ground connection string pendulum, its safe distance should be not less than the numerical value of " electric power safety working regulation " new regulation.Forbid to carry out ground short circuit without wire clamp by the method be wound around.Hitch point is if any earth point, and application clamp 8 or special copper rod make grounding connection; As without dead earth point, can utilize temporary grounding point, earth electrode 2 imbeds subterranean depth should be not less than 0.6m.
This earth connection should be kept properly.Before each use, carefully all should check that whether it is intact, annealed copper wire reveals without Naked, and nut does not get loose, otherwise must not use.
