Abstract
The utility model discloses a connector for a ground wire. The connector for the ground wire comprises a fixed rod and a fixed support. The fixed rod is disposed on the support, one end of the fixed rod is provided with a clamp, a clamping portion for clamping an article is formed between the clamp and the fixed support under the movement of the fixed rod, and a binding post is arranged on the fixed support. Due to the fact that the clamp arranged on the fixed rod of the fixed support and the existing ground wire jointly constitute an external casing protection grounding device used during electric power circuit outage overhauling or when an insulation bucket arm car is in live line operation, a conventional ground protection device formed by tapping a ground rod into a ground is avoided, grounding resistance is greatly reduced, the grounding deice is not damaged, the external casing protection grounding device can be stably and reliably used for a long time, and generally the grounding rod has a service life of about one year and then is scraped due to human factor or material aging while the connector for the ground wire can be used eternally. Therefore, the connector for the ground wire can greatly lowers the grounding resistance, and work efficiency and economic benefit are improved.
Description
Technical field
The utility model relates to a kind of electrical network repairing auxiliary device, the jockey of the ground wire protection circuit when particularly a kind of power circuit overhauls.
Background technology
The shell protective earthing work of when power circuit interruption maintenance ground connection work and aerial lift device with insulated arm are carried out live line working, carrying out; Being to prevent that the operating personnel from getting shocked or the most effective safety measure of electrostatic induction electric shock, also is one of most important work step in the electric power safety work.Conventional method is to adopt earth rod squeezed into hammer to play the ground connection effect in the soil, because a lot of circuits are in the area, cities and towns, is not easy to find the soil (being mostly concrete floor) that can squeeze into earth rod around the shaft tower, thus earth connection the very big difficulty of generation is set.On the other hand because earth rod and soil contact are less; And the easy corrosion of earth rod damages; And grounding resistance often is higher than the grounding resistance upper limit of electric power safety rules regulation, causes earth resistance bigger than normal, and work brings great potential safety hazard to electric power safety.Have, manpower is squeezed into earth rod wastes time and energy again, because firmly uneven when squeezing into earth rod in the soil with iron hammer, causes epimere crooked, and hammer is connected the termination with earth connection easily and damages often replacing, operating efficiency and low in economic efficiency with earth rod.
Therefore the earth connection protective device that needs a kind of simple in structure, easy to use, reliability and durability.
The utility model content
In view of this, the utility model technical problem to be solved provides a kind of earth connection protective device of simple in structure, easy to use, reliability and durability.
The utility model is realized through following technical scheme:
The earth connection connector that the utility model provides; Comprise fixed lever and fixed support; Said fixed lever is arranged on the fixed support; Said fixed lever one end is provided with grip block, and said grip block forms the clamping part that gripping object is stepped up moving down and between the fixed support of fixed lever, on the said fixed support binding post is set.
Further, also comprise handle, said handle is arranged at the other end of fixed lever.
Further, said fixed support is provided with fixing hole, and said fixed lever passes fixing hole.
Further, said fixedly sky is that internal thread is empty, and said fixed lever is an external thread rod.
Further, said binding post is a screw.
Further, the corresponding auxiliary section of said fixed support and grip block is a bending part, and said grip block is positioned at the bending part curved interior.
The beneficial effect of the utility model is: the shell protective earthing device when the utility model adopts the grip block be arranged on the fixed lever on the fixed support and existing earth connection to form power circuit interruption maintenance or aerial lift device with insulated arm jointly to carry out live line working; Avoided adopting earth rod has been squeezed into formed traditional earth protective device in the soil; This device has greatly reduced earth resistance, and (grounding resistance of grounding of pole line and ground network is very low; Be connected the back grounding resistance with it usually below 5 Europe; And adopt earth rod all about 5-10 Europe (field survey is comprehensive) usually, and can not damage earthing device, can steady in a long-termly use reliably; The general earth rod life-span will scrap because of artificial or material ageing about 1 year, and adopted the earth connection connector forever to use.Therefore, this device can greatly reduce earth resistance, increases work efficiency and economic benefit.
This earth connection connector construction is simple, easy to use, earth resistance is lower; Directly earth terminal is fixedly clamped on the grounding of pole line during use; Utilize the tower grounding net to carry out protective earthing (compare and squeeze into earth rod saving 2-3 minute, only need) less than 1 fen clock time.
Other advantages, target and the characteristic of the utility model will be set forth in specification subsequently to a certain extent; And to a certain extent; Based on being conspicuous to those skilled in the art, perhaps can from the practice of the utility model, obtain instruction to investigating of hereinafter.The target of the utility model and other advantages can realize and obtain through following specification and claims.
Description of drawings
For the purpose, technical scheme and the advantage that make the utility model is clearer, will combine accompanying drawing that the utility model is done further to describe in detail below, wherein:
The structure chart of the earth connection connector that Fig. 1 provides for the utility model embodiment.
Among the figure, 1 expression fixed lever, 2 expression fixed supports, 3 expression fixing holes, 4 expression grip blocks, 5 expression binding posts, 6 expression handles, 7 expression bending parts.
Embodiment
Below will be with reference to accompanying drawing, the preferred embodiment of the utility model is carried out detailed description.Should be appreciated that preferred embodiment has been merely explanation the utility model, rather than in order to limit the protection range of the utility model.
The structure chart of the earth connection connector that Fig. 1 provides for the utility model embodiment, as shown in the figure: the earth connection connector that the utility model provides comprises fixed lever 1, fixed support 2 and handle 6.
Said fixed lever 1 is arranged on the fixed support 2, and said fixed lever 1 one ends are provided with grip block 4, and said grip block 4 forms the clamping part that gripping object is stepped up moving down and between the fixed support 2 of fixed lever 1, on the said fixed support 2 binding post 5 is set.
Said handle 6 is arranged at the other end of fixed lever 1.Said fixed support 2 is provided with fixing hole 3, and said fixed lever 1 passes fixing hole 3.Said fixing hole 3 is that internal thread is empty, and said fixed lever 1 is an external thread rod.
Fixed lever in the present embodiment and fixed support adopt brass to be made into " rectifying " type main body; The fixed lever that a circular hole connecting band is movable lug shape grip block is offered in the fixed support upper end; This fixed lever is a screw rod; Screw tip band rotary handle, fixed support main body back are provided with the binding post that connects earth connection, and binding post is a screw.
Said fixed support 2 is a bending part 7 with grip block 4 corresponding auxiliary sections, and said grip block 4 is positioned at bending part 7 curved interior.
This device only needs the tower grounding wire clamp (need be removed tower grounding line oxide layer before using) in the middle of fixed support main body and grip block movable lug in use, uses rotary handle with it clamping, and making is connected firmly gets final product.Compare with original mode of operation, not only time saving and energy saving, and reliability is higher, and earth resistance is lower, can use for a long time.
