Abstract
The utility model discloses perpendicular grounding device in the range of a kind of column foot of electric power line pole tower, it includes earthing pole and down conductor, four by square frame and at least Grounding Grids of described earthing pole are constituted, Grounding Grids annular impartial setting is in square frame bottom, one end is arranged on four angles of square frame four down conductors respectively, Gua one end is arranged on gusset piece, then is arranged on four column foots of electric power line pole tower.Which solves the problem that earthing or grounding means floor space is big and corrosion is fast of electric power line pole tower, the construction period is shortened, reduce transmission line of electricity investment and power grid operation management expense.It is adapted to soil resistivity to be used in the column foot basis of 2000 Ω .m and following electric power line pole tower.
Description
Technical field
The utility model is related to technical field of power systems, especially vertical in the range of a kind of column foot of electric power line pole tower
Earthing or grounding means.
Background technology
Occupy certain ratio in the sum of power grid safety accident in China's lightening hazard, earthing or grounding means is transmission line of electricity
One of major measure of lightning protection, carries out the ground connection work of electric power line pole tower and ensures its task performance, to electricity net safety stable
Operation is particularly significant.At present, the earthing or grounding means of electric power line pole tower uses radial pattern horizontal grounding mostly, relies primarily on increase and penetrates
Line length realizes reducing pole tower ground resistance that the length of ray increases with the increase of soil resistivity, and earthing or grounding means is accounted for
Ground area also increases therewith.As economy and the high speed development of power grid construction, ultra-high-tension power transmission line are more and more, transmission line of electricity is walked
Corridor is also more and more crowded, often in engineering construction due to radial pattern horizontal grounding device installation damage young crops it is more, hinder
The problems such as agro-farming and obstructed by local resident, force the irrational compensation for crops of increase even transmission line of electricity to change road
Footpath scheme, not only increases transmission line of electricity investment, and influence construction period.In addition, the earthing or grounding means of electric power line pole tower is not
The corrosion-resistant safe and stable operation for also having a strong impact on power system.
Utility model content
The purpose of this utility model is regarding to the issue above, to propose a kind of earthing or grounding means of new electric power line pole tower,
Earthing pole is laid in column foot basic scope, earthing or grounding means floor space and ground connection ditch excavated volume, earthing pole and grounding lead is reduced
Offline use corrosion-resistant material.
The utility model solves the technical scheme that its technical problem used：It is included under earthing pole and grounding lead
Line, described earthing pole is made up of square frame with least four Grounding Grids, and Grounding Grids annular impartial setting is in square frame
Bottom, one end is arranged on four angles of square frame four down conductors respectively, and Gua one end is arranged on gusset piece, then is set
On four column foots of electric power line pole tower.
Described square frame is made up of copper facing round steel Bian of exothermic weld.
The Grounding Grids are made up of copper facing rod iron and connector.
The beneficial effects of the utility model are：The earthing or grounding means floor space for solving electric power line pole tower is big fast with corrosion
Problem, shorten the construction period, reduce transmission line of electricity investment and power grid operation management expense.It is adapted to soil resistivity to exist
Used in the column foot basis of 2000 Ω .m and following electric power line pole tower.

Connector.
Specific embodiment
In Fig. 1, Fig. 2 and Fig. 3, by square frame 1 and at least, four Grounding Grids 3 are assembled into earthing pole, and square frame 1 is by plating
Copper coin steel Bian is made of exothermic weld, and Grounding Grids 3 are connected through a screw thread with connector 7 by copper facing rod iron 6 and are made.Work as ground connection
When pole needs four armpit Grounding Grids 3 of Bian, four difference one end Bian of Grounding Grids 3 exothermic weld mode and square frame 1
Four right angles bottom connects.When earthing pole needs Bian with more than four armpit Grounding Grids 3, the difference of Grounding Grids 3 one end Bian
It is connected with the bottom of square frame 1 with exothermic weld mode annular equalization.Earthing pole the Bian quantity and length of Grounding Grids 3, need root
Determine according to soil resistivity size.Ground 5 of the earthing pole horizontal laying in the range of four column foot bases 4 of electric power line pole tower
Below.Four down conductors 2 are galvanizing round steel, and one end Bian is connected with 1 four angles of exothermic weld mode and square frame, Gua one end
Using oxygen -- acetylene passes through double bolts and is connected with four column foots of electric power line pole tower with plate weld, gusset piece is coupled.
