Description
Technical field
The present invention relates to a kind of earthing device, particularly relate to a kind of length apart from the tension anti-dropping earthing device.
Background technology
At present, the earthing device that we use substantially is through investigation, and external electric power system high-tension line there is no this device.The earthing device of domestic electric power system inner high voltage circuit also only is to rely on the gravity of earth clip self whereabouts with on the pinlock, 220kV and above transmission line are because the insulator string of self is long, thereby the operability that the line maintenance personnel are really used reduces greatly, has wasted the time greatly.Simultaneously because electric pressure is high, the large cause of clearance between wire and the shaft tower, so that package unit is heavy, action bars length is longer, thereby make the maintainer in articulating the ground process, when finishing fastening between earth connection and the wire, need cost regular hour and strength, in the process of rotating operation bar, because distance can guarantee that not necessarily earth connection and wire are fully fastening.
Because the defective that above-mentioned existing earthing device exists, the design people, positive research and innovation in addition apart from the tension anti-dropping earthing device, makes it have more practicality to the length of founding a kind of new structure.
Summary of the invention
Main purpose of the present invention is, overcome the defective that existing earthing device exists, and the length that a kind of new structure is provided is apart from the tension anti-dropping earthing device, technical problem to be solved is to make it workable, and laborsaving, thereby more be suitable for practicality, and have the value on the industry.
The object of the invention to solve the technical problems realizes by the following technical solutions.The length that proposes according to the present invention is apart from the tension anti-dropping earthing device, comprise, the conductor wire end ground connection hook, the hand that are connected by rope are successively pulled coaster and steel tower end fixture, this steel tower end fixture is connected by earth connection with conductor wire end ground connection hook, side at conductor wire end ground connection hook is fixedly connected with bolt connecting device, when articulating ground, is connected with insulating bar on this bolt connecting device, during electrical verification, this insulating bar is connected with the electroscope bottom.
Aforesaid length is apart from the tension anti-dropping earthing device, and wherein, described steel tower end fixture comprises the jig that is movably connected on the steel tower and the bolt that is flexibly connected with this jig, and described bolt is selected the M12 type.
Aforesaid length is apart from the tension anti-dropping earthing device, and wherein, described earth connection is the complete earth connection that ground connection and short circuit consist of, and complete earth connection is that the braiding of multiply annealed copper wire forms, and sectional area is not less than 25mm2.
By technique scheme, length of the present invention has following advantages at least apart from the tension anti-dropping earthing device:
Product of the present invention is workable, has greatly shortened the time of extension, dismounting ground wire in the use procedure of reality, adopts the design of hand-operated tackle, so that maintenance is more laborsaving.
In sum, the length of special construction of the present invention is apart from the tension anti-dropping earthing device, and it has above-mentioned many advantages and practical value, thereby more is suitable for practicality.
Above-mentioned explanation only is the general introduction of technical solution of the present invention, for can clearer understanding technological means of the present invention, and can be implemented according to the content of specification, below with preferred embodiment of the present invention and cooperate accompanying drawing to be described in detail as follows.
Description of drawings
Fig. 1 is that length of the present invention is apart from the structural representation of tension anti-dropping earthing device.
Embodiment
