Abstract

The invention, which belongs to the field of the power ground technology, discloses a ground wire connecting apparatus. Key points of the technical scheme are as follows: the provided ground wire connecting apparatus is mainly formed by a grounding electrode and a ground wire plugging head, wherein the grounding electrode and the ground wire plugging head are plugged with each other. One end of the ground wire plugging head is provided with a seat body connected with a ground wire and the other end has a cylindrical structure matching a grounding electrode plugging hole; and an arc groove is formed in the cylinder along the peripheral direction. A compression mechanism is arranged at the upper portion of the grounding electrode. According to the invention, the ground wire and the ground wire plugging head are installed together fixedly and firmly without any shedding; and the contact is reliable. Therefore, ground wire dismounting and mounting become convenient and rapid and the work efficiency is high; and leads with different types and specifications can be compacted rapidly. In addition, connection of the ground wire plugging head and the grounding electrode is realized by the spring pressure; and the grounding resistance is over 2 ohms based on testing, so that the regulation and requirement are met. Therefore, the provided apparatus has the high promotion and application value.

Description

A kind of ground wire connecting device
Technical field
The invention belongs to systems technology field power ground, be specifically related to a kind of ground wire connecting device.
Background technology
In the modern urban construction high-speed developing period, increasing power network, transformer station, open and close distribution user in one's power and produce thereupon, but code requires these electric power facilities must will have the grounding system of qualified specification, the method of attachment that earth connection and grounding system are traditional is not that welding is exactly to be spirally connected, particularly inconvenience in the middle of these various ground resistance tests afterwards, pretty troublesome and strengthened workload in the time that grounding system is tested.In addition, at present power network, transformer station, open and close the ground wire connecting device that distribution user uses in one's power, rectangular conductor and round conductor can not be general, and the jockey compression of connecting wires is firm not, in maintenance process, earth connection is non-easily to come off.
Summary of the invention
The technical problem that the present invention solves be to provide a kind of can meet that code requires again can handled easily and be applicable to the ground wire connecting device of different size wire.
Technical scheme of the present invention is: a kind of ground wire connecting device, it is characterized in that mainly being formed by the earth electrode of mutually pegging graft and earth connection connection-peg, wherein one end of earth connection connection-peg is provided with the pedestal being connected with earth connection, be provided with fixing fixture block at the upside of pedestal, on pedestal, be sliding combined with the movable clip block relative with fixing fixture block, this movable clip block is fixed on screw rod, screw rod is installed on pedestal, on the described movable clip block clamping face relative with fixing fixture block, be respectively equipped with pointed tooth, 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, spring, steel ball and cylindrical cavity, described steel ball and spring are set in turn in cylindrical cavity and realize the compression to spring by cover plate, 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.
The fixed installation of earth connection of the present invention and earth connection connection-peg is firm, difficult drop-off, contact is reliable, makes the work of dismounting earth connection convenient and swift, and operating efficiency is high, wire that can fast-holding different model specification, in addition, earth connection connection-peg of the present invention relies on spring pressure to realize with being connected of earth electrode, through testing earth resistance more than 2 Ω, meet code requirement, there is application value.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Drawing explanation: 1, earth electrode, 2, earth connection connection-peg, 3, pedestal, 4, fixing fixture block, 5, movable clip block, 6, screw rod, 7, pointed tooth, 8, cover plate, 9, spring, 10, steel ball, 11, cylindrical cavity.
Embodiment
Describe by reference to the accompanying drawings embodiment in detail.A kind of ground wire connecting device, mainly formed by the earth electrode 1 of mutually pegging graft and earth connection connection-peg 2, wherein one end of earth connection connection-peg 2 is provided with the pedestal 3 being connected with earth connection, be provided with fixing fixture block 4 at the upside of pedestal 3, on pedestal 3, be sliding combined with the movable clip block 5 relative with fixing fixture block 4, this movable clip block 5 is fixed on screw rod 6, screw rod 6 is installed on pedestal 4, on described movable clip block 5 clamping face relative with fixing fixture block 4, be respectively equipped with pointed tooth 7, the other end of earth connection connection-peg 2 is the cylindrical structure matching with earth electrode 1 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 8, spring 9, steel ball 10 and cylindrical cavity 11, described steel ball 10 and spring 9 are set in turn in cylindrical cavity 11 and realize the compression to spring 9 by cover plate 8, the downside of described cylindrical cavity 11 has diameter and is less than steel ball 10 diameters and the circular hole relative with earth electrode 1 spliced eye.
