Abstract
A high-voltage grounding structure comprises several grounding wires and connecting rings. The both ends of each grounding wire are connected with joints. The joints are in electric connection with the connecting rings. The grounding wires are in riveted joint with the joints. According to the utility model, the spring-shaped grounding wires are adopted, and the grounding wires are in riveted joint with the joints, and gaps do not exist in the connection portions of the grounding wires and the joints, so that spark will not occur, and the operation of a system and equipment with the grounding structure become more reliable and safer.
Description
Technical field
The utility model relates to high-voltage earthing field, particularly a kind of high-voltage earthing structure that adopts spring-like earth connection.
Background technology
In the electric power system and equipment of prior art, earth connection comprises the neutral line (N), protective wire (PE), the protection neutral line (PEN).Wherein, the function of the neutral line: the one, be used for connecing by rated voltage the single-phase electric devices that is phase voltage, the 2nd, be used for conducting unsymmetrical current and monophase current in three-phase system, the 3rd, the potential shift of the neutral point that is used for reducing loading.The function of protective wire: be the earth connection of using for guaranteeing personal safety, prevent electric shock accidents.The function of the protection neutral line: the function that has the neutral line and the protection neutral line concurrently.This protection neutral line is referred to as " zero line " in China, be commonly called as " ground wire ".
The interaction energy of electrical grounding is to prevent that the person from suffering thunderbolt, guarantee electrical system normally to move and prevent the harm of thunderbolt and static.By ground connection effect classification, comprise: the signal ground acc power ground connection of the protective earthing of system earth, equipment, lightning protection, bonding, anti-static grounding, electrical grounding and electronic equipment.By ground connection formal classification, comprise: by its arrangement, be divided into the leading utmost point and loop-type earth electrode; If by its shape, there are tubular, band shape and annular several citation form; If by its structure, there is dividing of the natural grounding utmost point and artificial earthing's utmost point.The earth connection of prior art, its line body and joint are connected to and are threaded, and have gap between screw thread, when being subject to External Force Acting, relatively move, and gap location can produce spark, may jeopardize the system of impact and equipment, has potential safety hazard.
Utility model content
Main purpose of the present utility model is to overcome above-mentioned shortcoming of the prior art, proposes the safer high-voltage earthing structure of a kind of connected mode.
The utility model adopts following technical scheme:
A high-voltage earthing structure, comprises some earth connections and connecting ring, and these earth connection two ends are all connected with joint, and this joint is electrically connected to connecting ring, it is characterized in that: described earth connection and joint are riveted joint.
According to the utility model one better embodiment, described earth connection is spring-like earth connection.
According to the utility model one better embodiment, described some earth connections are in connecting ring inner side by circle distribution.
According to the utility model one better embodiment, the quantity of described earth connection is 3.
According to the utility model one better embodiment, the quantity of described earth connection is 4.
From above-mentioned, to description of the present utility model, compared with prior art, the utlity model has following beneficial effect:
The utility model adopts the earth connection of spring-like, and earth connection is riveted joint with joint, and the two riveted joint part does not exist gap, and External Force Acting can not produce spark, makes the system and the equipment that are connected with this ground structure move more reliable and safety.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model earth connection;
Fig. 2 is the A-A cutaway view of Fig. 1;
The schematic diagram of Fig. 3 the utility model high-voltage earthing structure;
Wherein: 1, earth connection; 2, connecting ring;
11, joint.
Embodiment
Below by embodiment, the utility model will be further described.
With reference to Fig. 1, Fig. 3, a kind of high-voltage earthing structure, can be used in high-voltage electric power system and equipment, comprise four earth connections 1 and a connecting ring 2, earth connection 1 and its two ends of the metal material that this earth connection 1 is spring-like are all connected with joint 11, these earth connection 1 two ends and joint 11 are riveted joint (with reference to Fig. 2), and this joint 11 is electrically connected to connecting ring 2.
Four earth connections of the present utility model are for to be distributed in connecting ring 2 inner sides by circle distribution.Because joint 11 and earth connection 1 are riveted joint, the two riveted joint part closely connects, does not exist gap, and External Force Acting can not produce spark, makes high-voltage electric power system and the more reliable and safety of equipment operation.
Above are only embodiment of the present utility model, but design concept of the present utility model is not limited to this, allly utilizes this design to carry out the change of unsubstantiality to the utility model, all should belong to the behavior of invading the utility model protection range.
