Abstract
The utility model discloses a one-to-two grounding pile specially used for a substation five-prevention lock. The one-to-two grounding pile comprises a grounding pile, a lower portion of the grounding pile provided with a pressed tube type five-prevention lock, an upper portion of the grounding pile is provided with a horizontal metal plate, and two ends of the horizontal metal plate are provided with threaded holes. The one-to-two grounding pile can be well connected with an original grounding pile together, the purpose of increasing the grounding piles is achieved without destroying the original grounding pile, the potential safety hazard that grounding wires cannot be installed or grounding terminals are grounded irregularly (for example winding) due to the fact that the number of the grounding piles is insufficient can be prevented, and safety level is increased; the surface of the grounding pile is provided with a galvanizing coating layer, so that poor contact caused by surface aerugo can be surely prevented under the external climate of the substation, especially at welding positions; the threaded holes are disposed to enable the grounding wires to be disassembled and assembled rapidly; and the one-to-two grounding pile is simple in structure and easy to operate, the practical value is maximally developed under the condition of the same resources, and the one-to-two grounding pile is worth of being applied and popularized.
Description
Technical field
The utility model belongs to substation safety measure technical field, is specifically related to the anti-lock special one drag two ground stud of a kind of transformer station five.
Background technology
For guaranteeing substation safety operation, prevent misoperation fault, ensure personnel and device security in grid switching operation process, Guo Wang company belongs to use anti-misoperation system (anti-misoperation locking device) the standardized operation personnel's of transformer station operation behavior.This system possesses " five is anti-" function, that is: anti-on-load drawing disconnecting link; Anti-wrong diagnosis combination switch; Prevent switching on earth wire; Anti-live connection of ground wire; Prevent mistakenly entering charged chamber.
While wherein installing earth connection, use be the special ground stud of anti-misoperation system, one of this ground stud can only connect a set of ground wire.But the ground stud quantity of transformer station's installing is according to conventional exemplary operation configuration, at this moment in the time having the work of particular/special requirement or atypia work, ground stud lazy weight, causes and can not install earth connection or earth terminal ground connection (such as being wound around) lack of standardization, thus the potential safety hazard of staying.In CN 201611742 U, a kind of grounding terminal wiring card of all-purpose grounding wire is disclosed, comprise framework, framework comprises the coupling part between upper and lower two extensions and upper and lower two extensions that be arranged in parallel up and down, described upper extension and coupling part are equipped with screw, upper extension is by the screw ground connection band iron wiring card that has been threaded, and ground connection band iron wiring card comprises double-screw bolt and between two extensions and be fixedly arranged on the flat board of double-screw bolt lower end; The downside of lower extension is vertically installed with ground stud double-screw bolt, on ground stud double-screw bolt, is equipped with profile nut; The utility model be a kind of can be in transformer station anywhere carry out the grounding terminal wiring card of all-purpose grounding wire of ground connection; Although it has solved the problem of the ground connection of connecting wires, it easily causes and contacts insecurely between earth connection, therefore needs a kind of grounding form originally that neither destroys, and connects again ground wire grounding device closely.
Utility model content
The purpose of this utility model is to provide a kind of transformer station five simple in structure, easy and simple to handle and that earthing effect is good anti-lock special one drag two ground stud.
To achieve these goals, the scheme adopting is: the anti-lock special one drag two ground stud of a kind of transformer station five, comprise ground stud, and described ground stud bottom is that pressure pipe type five is anti-lock, described ground stud top is transverse metal plate, and described transverse metal sheet two ends arrange screwed hole.
The anti-lock top of described pressure pipe type five arranges the bolt of boss, and anti-the locking of described pressure pipe type five arranges wing nut.
Described transverse metal plate is fine copper metallic plate product.
Described pressure pipe type five is anti-lock is fine copper product.
The quantity of described screwed hole is two.
Described ground stud surface arranges galvanizing coating.
The utility model is arranged on script ground stud, make it can be good at linking together, make it can be in the situation that not destroying originally ground stud, realize the object that increases ground stud, avoid due to ground stud lazy weight, cause and can not install earth connection or earth terminal ground connection (such as being wound around) lack of standardization, and the potential safety hazard staying improves lsafety level; On ground stud surface, galvanizing coating is set, has ensured that it is in the outside weather of transformer station, can prevent the loose contact causing of becoming rusty of the surperficial pig copper, especially at weld; Screwed hole is set makes it earth connection can be carried out to dismounting fast; The utility model is simple in structure, easy and simple to handle, and in equal resources supplIes, county has brought into play its practical value to greatest extent, is worth application and promotes.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is further described:
Fig. 1 is structural representation of the present utility model,
Fig. 2 is the anti-lock structural scheme of mechanism of the utility model pressure pipe type five;
Fig. 3 is the local structure for amplifying schematic diagram of the utility model face coat.
Embodiment
As shown in Figure 1, Figure 2 and Figure 3: the anti-lock special one drag two ground stud of a kind of transformer station five, comprise ground stud, described ground stud bottom is that pressure pipe type five is anti-lock 3, and described ground stud top is transverse metal plate 1, and described transverse metal sheet 1 two ends arrange screwed hole 2.
Anti-lock 3 tops of described pressure pipe type five arrange the bolt 4 of boss, in described pressure pipe type five anti-lock 3, wing nut 5 are set.
Described transverse metal plate 1 is fine copper metallic plate product.
Described pressure pipe type five anti-lock 3 is fine copper product.
The quantity of described screwed hole 2 is two.
Described ground stud surface arranges galvanizing coating 6.
First the pressure pipe type five by this device is anti-lock in use that it is connected with earth connection originally for the utility model, then select one of them screwed hole on this device top to be connected with grounding apparatus originally by pressure pipe type five is anti-lock, make another ground connection screwed hole become for subsequent use, in the time of needs ground connection, direct connection can be used, simple and practical.
The utility model adopts pressure pipe type five anti-lock modes of being combined with metallic plate, has solved following problem: 1, originally due to ground stud lazy weight, cause and can not install earth connection or earth terminal ground connection (such as being wound around) lack of standardization, and the potential safety hazard staying; 2, at the two ends of metallic plate, screwed hole is set, realized wiring fast, efficient, contact closely; 3, because wiring pile long term exposure is in air, easily cause surface to occur rusty stain, cause loose contact, therefore done antirust coating on surface, ensure the erosion that weld and entirety are not subject to or few getter is waited, made can carry out fast in the time carrying out ground connection operation.The utility model is simple in structure, easy and simple to handle, under equal resources supplIes, has brought into play to greatest extent its practical value, is worth application and promotes.
