The utility model discloses the nonmetal earthing device of a kind of mesolow electric power system, comprise graphite earth electrode (1), it is characterized in that, be provided with graphite earth connection (2) in graphite body earth electrode (1), graphite earth connection (2) comprises the inner core section (22) reaching the outside linkage section (21) of graphite earth electrode (1) and be embedded in graphite earth electrode (1) inside.Nonmetal earthing device of the present utility model all adopts graphite material, and anticorrosive, antiacid alkali, cost are low, and long service life, reduces construction cost, and there is not the situation of corrosion failure, reduces electric power accident; Graphite earth connection is flexible foundation, and when earthing device needs parallel connection to use, with graphite rope by the colligation of graphite earth connection, when being distorted because of natural cause or bending, junction is easy fracture not, and does not need metal material, reduces construction cost further.
Description
Technical field
The utility model relates to earthing device, is specifically related to a kind of nonmetal earthing device be used in mesolow electric power system.
Background technology
Current China mesolow electric power system earthing device major part used is metal device, and material mostly is band iron or angle steel, will strengthen the model of earth electrode in the more serious area of soil salt alkalescence toward contact, but still can not solving device by the problem of corrosion.No matter be band steel or round steel, in order to reach good earthing effect, meet the requirements of resistance, during configuration, need to possess certain length, cause excavation area large, take up an area large problem and occur, be also difficult to solve in antitheft, and comparatively bother during transport construction.
Because metallic ground material exists some problem, over the past two years, nonmetal earthing device was widely adopted in overhead transmission line.Existing nonmetal earthing device comprises graphite earth electrode and metallic ground lines; need metallic ground wire bonding during earthing device earth; coastal or salt-soda soil is regional; metallic ground lines and its welding position are easy to be corroded; affect grounded capacity, and earthing device breaks down and can produce significant impact to electric power netting safe running.If do preservative treatment to metallic ground lines and welding position thereof, then can increase construction cost further.
Utility model content
For solve above-mentioned existing nonmetal earthing device perishable, there is potential safety hazard, technical problem that construction cost is high, the utility model provides a kind of novel uncorruptible graphite ground connection complex device.
Technical approach of the present utility model is: the nonmetal earthing device of a kind of mesolow electric power system, comprise graphite earth electrode (1), it is characterized in that, be provided with graphite earth connection (2) in graphite body earth electrode (1), graphite earth connection (2) comprises the inner core section (22) reaching the outside linkage section (21) of graphite earth electrode (1) and be embedded in graphite earth electrode (1) inside.
Further, graphite earth electrode (1) is cylinder.
Further, the inner core section (22) of graphite earth connection (2) is arranged on the central shaft of graphite earth electrode (1).
Further, the inside of graphite earth electrode (1) is embedded with and strengthens steel wire (3).
Further, strengthen steel wire (3) to comprise along the steel wire of graphite earth electrode (1) cross sectional arrangement with along the longitudinal steel wire arranged of graphite earth electrode (1).
Further, the cross section of graphite earth electrode (1) is plum blossom shape.
The nonmetal earthing device of a kind of mesolow electric power system that the utility model provides, compared with prior art, there is following beneficial effect: the nonmetal earthing device of (1) this programme all adopts graphite material, anticorrosive, antiacid alkali, cost are low, long service life, reduce construction cost, and owing to there is not the situation of corrosion failure, reduce electric power accident; (2) graphite earth connection is the graphite line of flexible foundation, when earthing device needs parallel connection to use, with graphite rope by the colligation of graphite earth connection, when being distorted because of natural cause or bending, junction is easy fracture not, and does not need metal material, further reduction construction cost, avoiding device is corroded; (3) graphite earth electrode volume is little, and excavation ground groove area is little, and greatly shorten the engineering time, and graphite material is pollution-free, soil protection and vegetation are not damaged; (4) graphite device is not easy to steal, and reduces the shock episodes because human factor produces; (5) the nonmetal earthing device of this programme adopts and vertically buries underground, not easily produces step voltage.
Accompanying drawing explanation
Fig. 1 is the utility model specific embodiment structural representation.
Fig. 2 is the cross sectional representation of the utility model specific embodiment.
In figure, 1-graphite earth electrode, 2-graphite earth connection, 21-linkage section, 22-inner core section, 3-strengthens steel wire.
Embodiment
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is elaborated, and following examples are to explanation of the present utility model, and the utility model is not limited to following execution mode.
As shown in the figure, the nonmetal earthing device of a kind of mesolow electric power system that this programme provides, comprise graphite earth electrode 1, be provided with graphite earth connection 2 in graphite earth electrode 1, graphite earth connection 2 comprises the linkage section 21 reaching graphite earth electrode 1 outside and the inner core section 22 being embedded in graphite earth electrode 1 inside.
In the present embodiment, graphite earth electrode 1 is cylinder, and the cross section of graphite earth electrode 1 is plum blossom shape, to increase the contact area of graphite earth electrode 1, reduces resistance.The inner core section 22 of graphite earth connection 2 is arranged on the central shaft of graphite earth electrode 1, and the inside of graphite earth electrode 1 is embedded with reinforcement steel wire 3, strengthening steel wire 3 comprises along the steel wire of graphite earth electrode 1 cross sectional arrangement with along the longitudinal steel wire arranged of graphite earth electrode 1, add and strengthen the intensity that steel wire 3 can strengthen graphite earth electrode 1, convenient installation and transport.
In the present embodiment, graphite earth connection 2 is the graphite line of flexible foundation, during installation, graphite earth electrode 1 is vertically buried underground, the linkage section 21 end crimping binding post of graphite earth connection 2 is connected to and is grounded on body, when needs parallel connection uses, to graphite earth connection 2 colligation of nonmetal earthing device in parallel be needed together with graphite rope, when graphite earth connection 2 falls short of, graphite line for subsequent use is lashed on graphite earth connection 2 by same available graphite rope, and the diameter of graphite line for subsequent use should be identical with the diameter of graphite earth connection 2.
The above is only preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
