Abstract
The invention discloses a plug device of a grounding system. The plug device of the grounding system is characterized in that the plug device of the grounding system is mainly formed by a grounding electrode and a grounding wire connecting plug, wherein the grounding electrode and the grounding wire connecting plug are connected mutually in an inserting mode. One end of the grounding wire connecting plug is fixedly connected with the ground wire through a press screw, the other end of the grounding wire connecting plug is of a cylindrical structure matched with a grounding electrode plugging hole, an arc-shaped groove is formed in the cylindrical body in the circumferential direction, a hold-down mechanism is arranged on the upper portion of the grounding electrode, the hold-down mechanism comprises a covering plate, a covering plate screw, a spring, a steel ball and a barrel-shaped cavity, the steel ball and the spring are arranged in the barrel-shaped cavity in sequence, the pressing of the spring is achieved through the covering plate and the covering plate screw, and a round hole is formed in the lower side of the barrel-shaped cavity, wherein the diameter of the round hole is smaller that that of the steel ball, and the round hole is opposite to the grounding electrode plugging hole. According to the plug device of the grounding system, the connection of the grounding wire connecting plug and the grounding electrode is achieved by relying on the pressure of the spring, experiments show that grounding resistance is lower than 2 ohms and meets the requirement of the system, and the plug device of the grounding system has popularization and application value.
Description
Technical field
The present invention relates to the jockey of system earth body and earth connection power ground, be specifically related to a kind of plug assembly of grounding system.
Background technology
In the Modernized City Construction high-speed developing period, increasing power network, transformer station, open and close distribution user in one's power and produce thereupon, but rules require these facilities must will have the grounding system of qualified standard, the traditional method of attachment of earth electrode and earth connection is not that welding is exactly to be spirally connected, in the middle of these various ground resistance tests afterwards, particularly inconvenience, pretty troublesome when grounding system is tested, and strengthened workload, test for ground is comparatively frequent in addition, has also caused various unnecessary wastes.
Summary of the invention
The technical problem that the present invention solves has been to provide and a kind ofly can have met the plug assembly that rules require again grounding system that can handled easily.Technical scheme of the present invention is: a kind of plug assembly of grounding system, it is characterized in that mainly by the earth electrode of mutually pegging graft and earth connection connection-peg, being formed, wherein one end of earth connection connection-peg is fixedly connected with by housing pin with earth connection, the other end of earth connection connection-peg is the cylindrical structure matching with earth electrode spliced eye, on this cylinder, be along the circumferential direction provided with arc groove, the top of described earth electrode is provided with hold-down mechanism, this hold-down mechanism comprises cover plate, cover plate screw, spring, steel ball and cylindrical cavity, described steel ball and spring are set in turn in cylindrical cavity and by cover plate and cover plate screw and realize the compression to spring, the downside of described cylindrical cavity has diameter and is less than diameter of the steel ball and the circular hole relative with earth electrode spliced eye.Earth connection connection-peg of the present invention relies on spring pressure to complete with being connected of earth electrode, and through test, earth resistance, below 2 Ω, meets system requirements, has application value.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Drawing explanation: 1, steel ball, 2, spring, 3, cover plate, 4, cover plate screw, 5, earth connection connection-peg, 6, earth electrode.
Embodiment
Describe by reference to the accompanying drawings embodiment in detail.A kind of plug assembly of grounding system, mainly by the earth electrode 6 of mutually pegging graft and earth connection connection-peg 5, formed, wherein one end of earth connection connection-peg 5 is fixedly connected with by housing pin with earth connection, the other end of earth connection connection-peg 5 is the cylindrical structure matching with earth electrode 6 spliced eyes, on this cylinder, be along the circumferential direction provided with arc groove, the top of described earth electrode 6 is provided with hold-down mechanism, this hold-down mechanism comprises cover plate 3, cover plate screw 4, spring 2, steel ball 1 and cylindrical cavity, described steel ball 1 and spring 2 are set in turn in cylindrical cavity and the compression realizing spring 2 by cover plate 3 and cover plate screw 4, the downside of described cylindrical cavity has diameter and is less than steel ball 1 diameter and the circular hole relative with earth electrode 6 spliced eyes.In use procedure, cylinder one end of earth connection connection-peg 5 is inserted in the spliced eye of earth electrode 5, by compressing steel ball 1 and arc groove on earth connection connection-peg 5 cylinders, match and be grounded being connected of the utmost point 6 and earth connection connection-peg 5, facilitate the insertion of earth connection connection-peg 5 and extract, also facilitate carrying out smoothly of postorder work in every, earth connection connection-peg 5 relies on spring 2 pressure to complete with being connected of earth electrode 6, through test, earth resistance is below 2 Ω, meet system requirements, there is application value.
More than show and described basic principle of the present invention, principal character and advantage, without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, and these changes and improvements all fall into claimed scope of the present invention.
