The utility model discloses have be convenient for be under construction pre -buried, construction convenience, ground resistance is little, the ground connection reliability is high, the security is good, the routine maintenance is convenient, is favorable to the earth connection installation rate, and is efficient.

Description

A kind of electric pole, table case grounding device
Technical field
This utility model relates to a kind of grounding device, particularly a kind of electric pole, table case grounding device.
Background technology
Grounding device is electric power overhaul personnel " life line " is also " line of saving one's life "; it is one safety curtain of protection workmen; can prevent construction line from sending a telegram here suddenly the injury to human body, it is possible to when playing specific fault, the charged person caused of metal watch case gets an electric shock injury.Grounding device includes earth lead and earthing pole.Earth lead is by copper core 25mm2Multifibres annealed copper wire makes, what problem of normal absence, and the position of earthing pole installing, the degree of depth, soil regime etc. directly influence the size of earth resistance, are related to the effect of ground connection.Specify according to " State Grid Corporation of China's electric power safety working regulation (distribution section) " 4.4.1 bar: when identifying indeed after no-voltage, should immediately by the high-tension distributing line of maintenance and equipment ground three-phase shortcircuit, job site respectively hold with job site in be likely to each branch line of anti-power transmission and all answer ground connection.4.4.14 bar regulation: during the no ground downlead of shaft tower, sectional area can be adopted more than 190mm2(such as φ 16mm round steel), the subterranean depth temporary grounding body more than 0.6m.In the prior art, what earthing pole adopted is length 1 meter, and diameter 16mm round steel is driven underground no less than 0.6 meter, then is connected with earth lead.After earthing pole has been installed at scene, often there is no measurement of Grounding Resistance, and in most cases, earth resistance exceedes setting 30 Ω, there is unsafe factor.Additionally, the construction of modern countryside, the road in urban district or even each villages and small towns, cement pavement has been laid in streets and lanes all, power department is all difficult during installing earth lead in distribution transformation, circuit repairing etc. are constructed, when carrying out the early stage inspection of the scene of a crime, rack one's brains to search the place that can install earthing pole, spend the longer time to reconnoitre at the scene.And installing earth lead before constructing, what have needs prolongation 30,50 meters long, takes more time, affects efficiency of construction, increases power off time and expands power failure range.And earthing pole is also seized every opportunity, in being installed in roadside flowerpot, have be directly inserted in mound, the first-class nonstandard situation of rubbish heap happens occasionally, earth lead performs practically no function, and loses due effect.
Utility model content
The purpose of this utility model is in that to overcome the deficiencies in the prior art part, and it is pre-buried to provide one to be easy to construction, easy construction, earth resistance is little, and Earthing Reliability is high, and safety is good, regular maintenance is convenient, is conducive to earth lead installation rate, a kind of electric pole that efficiency is high, table case grounding device.
A kind of electric pole, table case grounding device, include earth lead and earthing pole, its structural feature is in that: the physical dimension of described earthing pole is the angle bar of 50*5*1500mm, described earth lead is that round steel is constituted, and described earth lead adopts insulation tube to make insulation processing near that section on ground more than ground.
The grounding device of the present invention, the sectional area of earthing pole reaches 475mm2, more than the 190mm of regulatory requirements2.Earthing pole length becomes 1.5m, meet regulatory requirements no less than 0.6m, more than existing 1m, reach 0.3m it addition, long-pending with soil contact2, more than existing 0.05m2Therefore earth resistance can largely be reduced, adopt 10# round steel, if its expense is low, easy construction is attractive in appearance, within the scope of 3 meters of ground adopt φ 20PVC pipe make insulation processing have Distribution Network Failure occur and and earthing pole loose contact and cause charged, do not have potential safety hazard.
Described insulation tube is PVC insulation tube.
Described angle bar is galvanized angle iron.
Described round steel is galvanized steel bar.
The top of earth lead is provided with bow-shaped structural.
Bow-shaped structural is set on the top of earth lead, it is simple to the installation of earth lead.
The bottom of described earthing pole is set to cone structure.
The top of described earthing pole is cone structure.
Cement pavement for burying earthing pole underground adopts the mode got into the cave to process, then is imbedded in hole by earthing pole.
Gold steel can being adopted when getting into the cave to creep into row get into the cave, adopting gets into the cave in this way has: invest little, easy construction, speed fast, when getting into the cave almost without noise, vibrations will not be produced, destructive power will not be produced, scope, wound surface little (only 1600mm2), road surface recover easily attractive in appearance, will not easily caused by the dislike of surrounding user, complaint and the situation stopping construction.
In sum, this utility model following advantage compared to existing technology:
Being easy to construction pre-buried, easy construction, earth resistance is little, and Earthing Reliability is high, and safety is good, and regular maintenance is convenient, is conducive to earth lead installation rate, and efficiency is high.

Detailed description of the invention
Below in conjunction with embodiment, this utility model is described in more detail.
Embodiment 1
A kind of electric pole, table case grounding device, include earth lead 2 and earthing pole 1, the physical dimension of described earthing pole is the galvanized angle iron of 50*5*1500mm, and described earth lead is that galvanized steel bar is constituted, and adopts PVC insulation tube 4 to make insulation processing in more than ground 3 meters of long scopes.The top of earth lead is provided with bow-shaped structural 3.The bottom of described earthing pole is arranged to cone structure.
This utility model is when mounted:
1, adopt φ 160 water mill gold steel to bore broken cement pavement, form 1600mm2Circular hole.
2,50*5*1500mm galvanized angle iron earthing pole sledgehammer is hammered into circular hole.
3, pvc pipe or cable heat shrinkage bush are packed into 10# galvanized steel bar earth lead.Galvanized steel bar is welded with galvanized angle iron.According to cable heat shrinkage bush, then need to carry out pyrocondensation process.
4, earth wire galvanized steel bar is fixed.
5. earth lead top is fabricated to " bow " type earth terminal.
The not described part of the present embodiment is same as the prior art.
