Description
Technical field
The utility model belongs to the power supply apparatus field, particularly a kind of rural power grids ground path.
Background technology
Along with carrying out of new Rural Electrification Construction, 0.4KV the low pressure rural power grids are fast-developing, according to the relevant technologies code requirement, 0.4KV the low pressure rural power grids 7-8 base bar neutral line needs iterative earthing, namely at regular intervals or at the circuit turning, all earth connection to be set, therefore, in 0.4KV low pressure rural power grids, a large amount of earth connections need be set.Existing ground path is by copper lead-in wire, the neutral line to be connected with the earth polar, then the earth polar is imbedded underground, and whole piece lead-in wire pastes and ties up on electric pole, and ground lead is exposed to the outside fully.This ground path as phase deviation occurs, can cause earth connection charged, has great potential safety hazard; In addition, use a large amount of copper lead-in wires to increase the financial resource and material resource input, and ground lead pastes and ties up on electric pole, hinder in maintenance repair and step on the bar operation.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of electric pole structure, economical with materials, circuit hiding, safe rural power grids ground path of utilizing is provided.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of rural power grids ground path, it is characterized in that: formed by the built-in round steel of electric pole, lead-in wire, clamping ring, earth polar, lead-in wire is connected between transmission line zero line and the built-in round steel of electric pole, clamping ring is installed in the built-in round steel of electric pole bottom, the earth polar is installed on clamping ring the outside and is embedded in undergroundly, and transmission line zero line, lead-in wire, the built-in round steel of electric pole, clamping ring, earth polar are electrically connected to successively.
And described clamping ring is a ring shape metallic article of being made by band steel.
Advantage of the present utility model and good effect are:
1. these rural power grids ground path can utilize the electric pole structure, and economical with materials is saved and dropped into;
2. these rural power grids ground path utilizes the electric pole structure, and circuit hiding is safe, steps on the bar operation when being conducive to maintenance repair;
3. these rural power grids ground path design science is reasonable, have can utilize electric pole structure, economical with materials, saving input, circuit hiding, safe, be conducive to maintenance repair and step on the advantages such as bar operation, be a kind of rural power grids ground path with higher innovation.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Description of reference numerals:
The built-in round steel of 1-electric pole, 2-lead-in wire, 3-transmission line zero line, 4-electric pole, 5-ground, 6-clamping ring, 7-earth polar.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing, by specific embodiment.Following examples are descriptive, are not determinate, can not limit protection range of the present utility model with this.
A kind of rural power grids ground path, formed by the built-in round steel 1 of electric pole, lead-in wire 2, clamping ring 6, earth polar 7, lead-in wire is connected between transmission line zero line 3 and the built-in round steel of electric pole, clamping ring is installed in the built-in round steel of electric pole bottom, the earth polar is installed on clamping ring the outside and is embedded in ground 5 times, and transmission line zero line, lead-in wire, the built-in round steel of electric pole, clamping ring, earth polar are electrically connected to successively.
Clamping ring is a ring shape metallic article of being made by band steel, is fixedly mounted with mutually with the built-in round steel of all electric poles bottom.
The built-in round steel of electric pole is a plurality of, is circle-shaped uniform being installed in electric pole 4.
The electric pole bottom is imbedded underground approximately 2 meters.
Approximately 20 centimetres far from ground, top, earth polar.
The operation principle of these rural power grids ground path is:
These rural power grids ground path directly utilizes the built-in round steel of electric pole as earth lead, can save material, and saves and drops into; And the built-in round steel of electric pole is formed on electric pole inside, can not cause adverse effect to climbing the electric pole operation; The transmission line zero line is electrically connected to successively with the built-in round steel of lead-in wire, electric pole, clamping ring, the earth polar of this device, can play the zero line grounding effect; Clamping ring is a ring shape metallic article of being made by band steel, is fixedly mounted with mutually with the built-in round steel of all electric poles bottom, and is convenient, flexible when the built-in round steel of electric pole top is connected with lead-in wire, is connected with the built-in round steel of any one electric pole and all can; Check as need whether ground connection is good, 20 centimeters are shaken survey to the earth polar and are got final product under shaft.
Although disclose for the purpose of illustration embodiment of the present utility model and accompanying drawing, but it will be appreciated by those skilled in the art that: in the spirit and scope that do not break away from the utility model and claims, various replacements, variation and modification are all possible, therefore, scope of the present utility model is not limited to embodiment and the disclosed content of accompanying drawing.
