Description

Long apart from tension force run-resistant earthing device
Technical field
The present invention relates to a kind of earthing device, particularly relate to a kind of length apart from tension force run-resistant earthing device.
Background technology
At present, the earthing device that we use basically is through investigation, and external electric power system high-tension line does not still have this device.The earthing device of domestic electric power system inner high voltage circuit also only is to rely on earth clip self falling gravity 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.Owing to the big cause of clearance between electric pressure height, lead and the shaft tower, make package unit heavy simultaneously, action bars length is longer; Thereby make the maintainer in articulating the ground process; When accomplishing fastening between earth connection and the lead, need cost regular hour and strength, in the process of rotating operation bar; Because distance can guarantee that not necessarily earth connection and lead are fastening fully.
Because the defective that above-mentioned existing earthing device exists, the design people actively studies innovation, apart from tension force run-resistant earthing device, makes it have more practicality in the hope of 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 tension force run-resistant earthing device, and technical problem to be solved is to make it workable, and laborsaving; Thereby be suitable for practicality more, and have the value on the industry.
The object of the invention and solve its technical problem and adopt following technical scheme to realize.The length that proposes according to the present invention comprises that apart from tension force run-resistant earthing device the conductor wire end ground connection hook, the hand that are connected through rope are successively pulled coaster and iron tower end fixture; This iron tower end fixture is connected through earth connection with conductor wire end ground connection hook; On a side of conductor wire end ground connection hook, be fixedly connected with bolt connecting device, when articulating ground, be 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 tension force run-resistant earthing device, and wherein, said iron tower end fixture comprises jig that is movably connected on the iron tower and the bolt that flexibly connects with this jig, and said bolt is selected the M12 type for use.
Aforesaid length is apart from tension force run-resistant earthing device, and wherein, said earth connection is the complete earth connection that ground connection and short circuit constitute, and complete earth connection forms for the braiding of multiply annealed copper wire, and sectional area is not less than 25mm2.
By technique scheme, length of the present invention has advantage at least apart from tension force run-resistant earthing device:
Product of the present invention is workable, in the use of reality, has shortened extension greatly, has disconnected time of ground wire, adopts the design of hand-operated tackle, makes that maintenance is more laborsaving.
In sum, the length of special construction of the present invention is apart from tension force run-resistant earthing device, and it has above-mentioned many advantages and practical value, thereby is suitable for practicality more.
Above-mentioned explanation only is the general introduction of technical scheme of the present invention, understands technological means of the present invention in order can more to know, and can implement according to the content of specification, below with preferred embodiment of the present invention and conjunction with figs. specify as after.
Description of drawings
Fig. 1 is the structural representation of length of the present invention apart from tension force run-resistant earthing device.
Embodiment
Reach technological means and the effect that predetermined goal of the invention is taked for further setting forth the present invention, below in conjunction with accompanying drawing and preferred embodiment, specific embodiments of the invention specify as after.
As shown in Figure 1, long apart from tension force run-resistant earthing device, comprise; The conductor wire end ground connection hook 2, the hand that are connected through rope 1 are successively pulled coaster 4 and iron tower end fixture 3, and this iron tower end fixture 3 and conductor wire end ground connection hook 2 are connected through earth connection 8, and conductor wire end ground connection links up with 2 can adapt to 220KV and above various wire type; And interlock fully, and in reality, adopt light material; Conduct electricity very well, on a side of conductor wire end ground connection hook 2, be fixedly connected with bolt connecting device 7, when articulating ground; Be connected with insulating bar 5 on this bolt connecting device 7, during electrical verification, this insulating bar 5 is connected with electroscope 6 bottoms; Iron tower end fixture 3 comprises jig that is movably connected on the iron tower and the bolt that flexibly connects with this jig; Jig can conform to 220KV and above iron tower tower material coupling, and bolt is selected the M12 type for use, and earth connection 8 is the complete earth connection that ground connection and short circuit constitute; Complete earth connection forms for the braiding of multiply annealed copper wire, and sectional area is not less than 25mm2.
The course of work of the present invention is:
1, electrical verification, insulating bar 5 is connected with electroscope 6, and the maintainer can implement electrical verification to the circuit of site examining and repairing earlier.
2, after electrical verification finishes, regain electroscope 6, insulating bar 5 is connected with bolt connecting device 7; During hanging earthing conductor, long iron tower end fixture 3 apart from tension force run-resistant earthing device can be fixed by bolts on the iron tower, specifically in use; During hanging earthing conductor, the maintainer is displaced to iron tower cross-arm position on tangent tower, strain tower, uses insulating bar 5 easily earth connection and hook to be chosen to the lead top; Loosen earth connection, conductor wire end ground connection hook 2 is put to the lead bottom, pull coaster 4 through the hand under the iron tower end fixture 3 earth connection is tightened up; Conductor wire end ground connection hook 2 is caught on lead and closely contact, earth connection just hangs up properly, when disconnecting ground wire; At first using hand under the iron tower end fixture 3 to pull coaster 4 loosens earth connection; Lead earth connection hook 2 and lead are broken away from, regain earth connection 8, the set bolt on the dismounting iron tower end fixture 3 breaks away from itself and iron tower and gets final product.
The above only is preferred embodiment of the present invention, is not the present invention is done any pro forma restriction; Though the present invention discloses as above with preferred embodiment; Yet be not in order to limiting the present invention, anyly be familiar with the professional and technical personnel, in not breaking away from technical scheme scope of the present invention; When the technology contents of above-mentioned announcement capable of using is made a little change or is modified to the equivalent embodiment of equivalent variations; In every case be the content that does not break away from technical scheme of the present invention, to any simple modification, equivalent variations and modification that above embodiment did, all still belong in the scope of technical scheme of the present invention according to technical spirit of the present invention.
