Abstract
The utility model relates to an electric power single-lever point type grounding device for urban areas, comprising an electric power single lever, wherein a foundation is arranged below the electric power single lever which is connected with a grounding module by a grounding downlead; and the grounding module is arranged under the ground. The electric power point type grounding device for urban areas can be led to the grounding module only by one grounding downlead instead of original grounding net inlaying mode, thus eliminating the occupation area of the grounding device, simultaneously avoiding the influence on various underground pipelines of passenger roads, saving related compensation expense, greatly reducing the engineering cost, being in line with the requirements of the national power grid on resource-saving and environment-friendly type construction of electric power circuits.
Description
Technical field
The utility model relates to a kind of power circuit thunder proof protection ground pattern, specifically relates to a kind of ground connection pattern that is applied to the electric power single pole in the intensive and better area of soil property of city Route for pedestrians underground piping.
Background technology
As depicted in figs. 1 and 2, existing power tower grounding net 6 is cubic type, and four jiaos add radial ground connection radiation 7; Look the soil resistivity difference, the length of ground connection radiation 7 is between 10～50 meters, this is fine for open-air opening, but use for the city, the intensive area of underground piping such as Route for pedestrians particularly, ground network exist floor space big, influence underground piping, be difficult to problem such as construction, therefore, the minimizing floor space, to avoid the influence to various underground utilities be the problem that the Electric Design personnel need solve.
The utility model content
The technical problems to be solved in the utility model be city electric force pole tower ground network floor space big, influence underground piping, constructional difficulties, provide a kind of floor space little, to underground pipeline do not have influence, the easy city usefulness electric power single pole point type earthing device of constructing.
The technical solution of the utility model realizes in the following manner:
A kind of city comprises the electric power single pole with electric power single pole point type earthing device, and electric power single pole below is provided with the basis, and described electric power single pole links to each other with earthing module by down conductor, and earthing module is arranged on subsurface.
Preferred version one above-mentioned earthing module is arranged on basic side.
Preferred version two above-mentioned earthing modules are arranged on basic lower end.
Above-mentioned earthing module is cylindrical or quincunx earthing module.
Above-mentioned down conductor is zinc-plated round steel.
The utility model has been cancelled original ground network system of laying, only cause earthing module by a down conductor, so just eliminate the floor space of the earthing device of knowing clearly, avoided influence simultaneously to the underground various pipelines of Route for pedestrians, saved relevant damages, greatly reduced project cost, met national grid power circuit " resource-conserving, environmentally friendly " requirements on Construction.
Description of drawings
Fig. 1 is a prior art electric force pole tower ground network schematic diagram;
Fig. 2 is the A-A generalized section of Fig. 1;
Fig. 3 is the structural representation of the utility model embodiment 1;
Fig. 4 is the structural representation of the utility model embodiment 2.
Embodiment
As shown in Figure 3, the utility model comprises electric power single pole 1, and electric power single pole 1 below is provided with basis 5 (pile type foundations), and described electric power single pole 1 links to each other with earthing module 3 by down conductor 2, and earthing module 3 is arranged on ground 4 times.Described earthing module 3 is arranged on basic 5 sides.
This soil resistivity that uses novel place to use is about 100 Ω m.Earthing module 3 requires to adopt the cylindrical or quincunx earthing module of long-acting nothing corrosion, generally adopts polylith to be used in combination according to the soil resistivity earthing module; Down conductor 2 adopts zinc-plated round steel.
Adopt technique scheme, cancelled original ground network system of laying, only cause earthing module 3 by a down conductor 2, eliminated the ground network floor space, avoided influence to the underground various pipelines of Route for pedestrians, exempt relevant damages, greatly reduced project cost, met national policy.
As shown in Figure 4, described earthing module 3 is arranged on basic 5 lower ends, and other structures are with embodiment 1.
