Abstract
The utility model discloses a tower grounding net that area is little, including horizontal ground connection frame, horizontal ray grounding body and a plurality of perpendicular grounding body, this horizontal ray grounding body one end is connected with horizontal ground connection frame, evenly distributed such as a plurality of perpendicular grounding bodies are at horizontal ground connection frame. Novel earth mat may not emit the ray basically and the ground connection frame is less than traditional earth mat, has reduced ground connection area and ground connection ditch excavation volume, novel earth mat adopt not have corrodes the perpendicular earthing pole of combination, but near the limited vacant soil in make full use of shaft tower foundation ditch lay perpendicularly downwards, further reduce area.
Description
Technical field
The utility model relates to ground network, the tower grounding net that especially a kind of floor space is little.
Background technology
According to statistics, power supply department all encounter in the work progress of the multinomial transmission line of investment construction tower grounding net excavation difficulty pays for difficulty greatly, clearly, local resident stops the problems such as construction.Under, government day by day rare in land resource advocates the social form of harmonious society energetically, the disadvantage of traditional ground network becomes increasingly conspicuous.
As Fig. 1, traditional earth mat traditionally host will rely on ray length to realize the object reducing earth resistance, and ray length increases along with the increase of soil resistivity.This runs in the opposite direction with the countermeasure reducing earth mat floor space, clearly needs to carry out larger improvement to traditional earth mat.
Therefore, under not destroying pole and tower foundation structure, ensureing that earth resistance meets the precondition of safe operation, reduce the scope of laying of tower grounding net, increase the service life of ground network, reduce the developing direction that the difficulty of construction of ground network is novel earth mat.
Utility model content
For solving the problems of the technologies described above, reducing earth mat floor space, improving the ground network operation time limit, the purpose of this utility model is to provide the little and long-life tower grounding net of a kind of floor space.
The technical solution adopted in the utility model is:
The tower grounding net that floor space is little, comprises horizontal grounding frame, horizontal rays earth electrode and some Grounding Grids, and this horizontal rays earth electrode one end is connected with horizontal grounding frame, and described some Grounding Grids etc. are evenly distributed on horizontal grounding frame.
Described horizontal grounding frame is square box, and horizontal rays earth electrode is connected to one jiao of square box.
The tower grounding net that described floor space is little also comprises round steel under the hot galvanizing grounding lead be connected with horizontal grounding frame.
The tower grounding net that described a kind of floor space is little also comprises infrared sensing switch, liquid crystal indicator, server, infrared sensing switch is for monitoring the status signal of round steel under hot galvanizing grounding lead, liquid crystal indicator is provided with the remote alarm interface that can be connected with infrared sensing switch, liquid crystal indicator is connected with server through S485 standard interface, and server is connected to the communication terminal to electric substation's distant place concentrator station transmission related data through grid line.
Described Grounding Grids is non-corrosive assembled grounding electrode.
The beneficial effects of the utility model:
1), novel earth mat substantially can not release ray and grounding frame is less than traditional earth mat, decreases ground connection floor space and ground connection ditch excavated volume;
2), novel earth mat adopts corrosion-free combination vertical earth electrode, can make full use of vacant soil limited near shaft tower foundation ditch and lay vertically downward, reduce floor space further.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
Fig. 1 is the schematic diagram of traditional earth mat;
Fig. 2 is the schematic diagram of the utility model earth mat.
Embodiment
As shown in Figure 2, the tower grounding net that a kind of floor space of the present embodiment is little, comprise horizontal grounding frame 10, horizontal rays earth electrode 20 and some Grounding Grids 30, this horizontal rays earth electrode 20 one end is connected with horizontal grounding frame 10, and described some Grounding Grids 30 etc. are evenly distributed on horizontal grounding frame 10.
Concrete, horizontal grounding frame 10 is square box, horizontal rays earth electrode 20 is connected to one jiao of square box, and the tower grounding net that floor space is little also comprises round steel 40 under the hot galvanizing grounding lead be connected with horizontal grounding frame, and Grounding Grids 30 is non-corrosive assembled grounding electrode.
Adopt the novel earth mat of the technical program compared with traditional earth mat, as following table 1.
Table one
Through upper table analysis can: adopt the novel earth mat of vertical grounding electrode technology to greatly reduce in floor space.Soil resistivity has covered most tower grounding soil regime engineering reality from 500 ~ 3000 Ω M, therefore by adopting the Novel connecting earth polar technology of vertical grounding electrode to be the target setting that can realize " reducing floor space 50% " completely.
In addition, for a long time, tower grounding net is all that earth connection is placed on scene, by artificial to round steel 40(earth connection under on-site verification hot galvanizing grounding lead) position at current place, grasp that can not be real-time, Novel connecting earth mat also comprises infrared sensing switch, liquid crystal indicator, server, infrared sensing switch is used for the status signal of earth connection, liquid crystal indicator is provided with the remote alarm interface that can be connected with infrared sensing switch, liquid crystal indicator is connected with server through S485 standard interface, server is connected to the communication terminal to electric substation's distant place concentrator station transmission related data through grid line.
Because infrared sensing switch is connected with liquid crystal indicator, liquid crystal indicator is connected with server, and server can accept the state of earth wire signal of infrared switch reflection, signal is uploaded to the communication terminal distally concentrator station transmission of electric substation simultaneously.Earth connection situation not in place occurs, and monitoring personnel can by monitoring that computer is observed, thus can the earth connection situation not in place of manual monitoring electric substation, achieves unattended good result.
The foregoing is only preferred embodiments of the present utility model, the utility model is not limited to above-mentioned execution mode, as long as the technical scheme realizing the utility model object with basic same approach all belongs within protection range of the present utility model.
