Abstract
The utility model provides a simple quick grounding device for a distribution network tower. The simple quick grounding device includes multiple layers of equally spaced, horizontally disposed copper-clad steel annular grounding rings, a plurality of copper-clad steel longitudinal grounding drill rods fixed on the layers of copper-clad steel annular grounding rings and with vertical and downward rod bodies, and a plurality of copper-clad steel horizontal grounding drill rods fixed on a combining portion of the copper-clad steel annular grounding rings and the copper-clad steel horizontal grounding drill rods and with horizontal and outward rod bodies. Through such hierarchical combination and overall connection, a cage-type structure frame is formed and copper-clad steel grounding drill rods in close contact with the earth are uniformly distributed on the periphery and bottom of the frame. In addition, soil and a water conservation controlled release agent are filled uniformly in the cage-type structure frame buried underground. The simple quick grounding device has the outstanding advantages of firstly simple quick grounding of the distribution network tower and effective prevention of lightning damage to ensure the safe operation of the line; simple structure, easy manufacture, high cost performance of the used copper-clad steel material and easy implementation; and thirdly convenient construction.
Description
Technical field
The utility model relates to a kind of tower grounding facility of applying in network system, particularly relates to a kind of simple and fast earthing device.
Background technology
At present, in China's network system, there is part distribution shaft tower there is no earthing device, for the distribution shaft tower that earthing device is housed, also existing lightning current can not, from shaft tower lightning rod, major hidden danger through from earthing device to the quick earial drainage of the earth, be the key factor that causes distribution lightning protection capability low.What reason was that existing grounding-for-lightning device adopts is galvanized steel, and conductance is low.Experimental data shows: using the conductance of galvanized steel earth rod is only 8.6% of fine copper earth rod conductance, and under thunder and lightning high-frequency current impacts, the very high earial drainage of its impulse earthed resistance has some setbacks.
Summary of the invention
Goal of the invention of the present utility model is: for network system provides a kind of simple in structure, convenient, earial drainage shaft tower simple and fast earthing device fast of constructing.
Realize the present utility model object, adopt following technical proposals:
A kind of simple and fast earthing device, it is characterized in that: include multilayer equidistantly, the copper covered steel annular ground connection circle of horizontal positioned, many be fixed on that each layer of copper covered steel annular ground connection circle is upper, the vertical longitudinal ground connection hammer drill of copper covered steel down of the body of rod, and be fixed on copper covered steel annular ground connection circle and the longitudinal ground connection hammer drill of copper covered steel joint portion, the horizontal ground connection hammer drill of body of rod copper covered steel horizontally outward, by layering combination like this, whole connection, composition cage construction framework, the even cloth in its surrounding and bottom the copper covered steel ground connection hammer drill with the earth close contact; And evenly filling soil and water-holding slow-release agent in being embedded in underground cage construction framework.
The utility model simple and fast earthing device, the principle that can realize the lightning current of releasing is fast:
1. the utility model earthing device, what use is that conductance is higher than the copper covered steel of 4.8 times of galvanized steels, not only improved the conductance of earth electrode, and because the magnetic permeability of copper is only 1/636 of steel, two kinds of performance combinations, under thunder and lightning high-frequency percussion current conditions, the impulse earthed resistance of copper covered steel earth rod is much lower more than galvanized steel.Meanwhile, its thermal stability, corrosion resistance are all better than galvanized steel.
2. aspect apparatus structure: simple and fast earthing device, by copper covered steel annular ground connection circle and the longitudinal ground connection hammer drill of copper covered steel, via layering combination, whole connection, form symmetrical cage metal framework, the surrounding of framework and bottom are all uniform-distribution with water conservancy diversion hammer drill and the earth close contact, this device is because there being the earth electrode of symmetrical horizontal distribution, can enter ground from surrounding line surge current sharing, and because Jia Long the length of horizontal grounding, earth resistance is reduced, and what be more conducive to lightning current leaks into the earth fast.
3. experiment confirms: the direct positive correlation of the impulse resistance of earth electrode and soil moisture, the impulse current of different frequency there will be larger response difference with soil moisture difference.So soil resistivity is the most important factor that affects grounding system validity.
Filling soil and water-holding slow-release agent in this earthing device, can keep soil resistivity stable for a long time.This three technology measure, has guaranteed the simple and easy of distribution tower grounding device and the quick reliability of earial drainage.
The advantage of the utility model simple and fast earthing device is: 1. can realize the fast simple ground connection of distribution shaft tower, effectively prevent that thunder and lightning from destroying and guarantee line security operation.2. apparatus structure simpler production is easy, and the copper covered steel material cost performance of use is high, is convenient to implement.3. engineering construction is convenient.
Accompanying drawing explanation
Fig. 1 is the utility model simple and fast earthing device perspective view
Mark in figure: the 12 copper covered steel annular ground connection circles that are horizontal positioned, 13 be the vertical longitudinal ground connection hammer drill of copper covered steel down of the body of rod, and 14 is the horizontal ground connection hammer drill of copper covered steel horizontally outward, and 15 is filling soil and water-holding slow-release agent in device.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described.
As shown in Figure 1: simple and fast earthing device, include multilayer equidistantly, the copper covered steel annular ground connection circle 12 of horizontal positioned, many be fixed on each layer of copper covered steel annular ground connection circle 12, the vertical longitudinal ground connection hammer drill 13 of copper covered steel down of the body of rod, and the horizontal ground connection hammer drill 14 of joint portion, body of rod copper covered steel horizontally outward that is fixed on copper covered steel annular ground connection circle 12 and the longitudinal ground connection hammer drill 13 of copper covered steel, by layering combination like this, whole connection, composition cage construction framework, the even cloth in its surrounding and bottom the copper covered steel ground connection hammer drill with the earth close contact; And evenly filling soil and water-holding slow-release agent 15 in being embedded in underground cage construction framework.Be embedded in underground cage construction framework, in the surrounding of its copper covered steel annular ground connection circle, be all evenly distributed with the copper covered steel ground connection hammer drill of the lightning current of releasing, improved release speed and the efficiency of lightning current.
In cage construction framework, in even filling soil and water-holding slow-release agent 15 situations, can keep for a long time soil resistivity stable, thereby keep the stable of earthing device usefulness.
This earthing device can be configured to: standard type shaft tower insulator crossarm assembly, extended pattern shaft tower insulator crossarm assembly, monolateral extended insulator crossarm assembly, and use in other any type of cross arm of tower assembly.
