Detailed Description
In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise. All directional indicators in the embodiments of the present invention (such as upper, lower, left, right, front, rear, top, bottom … …) are only used to explain the relative position, motion, etc. of the components in a particular position (as shown in the drawings), and if the particular position is changed, the directional indicator is changed accordingly. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.
Furthermore, reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the invention. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
The applicant further analyzes the technical problems of complex and large limitation of the broken strand repairing technology in the overhead conductor and the reasons why the broken strand of the conductor is generated, and learns that:
the junction at suspension clamp and wire all is twined tightly with aluminium belting, and under long-time effect, aluminium belting is probably taken place to become flexible, produces the deposit thing or the surface is by oxidation to cause the unusual increase of contact resistance, when overhead transmission line receives the influence of foreign matters such as bird's injury, thunderbolt, insulator chain electric arc flashover, the short circuit power frequency takes place this moment, and it is the unusual contact resistance of continuous flowing through, and produces a large amount of heats at the in-process of flowing through. Until the temperature reaches the melting point of the aluminum wire, the wire is broken. Another situation is that the lever span and the head are not reasonable. Because expend with heat and contract with cold, the sag increase between the wire, external force effect under wind collides mutually between wire and the wire, produces alternate short circuit, takes place electric arc, under the effect of electric current, when the temperature reached aluminium conductor's melting point, causes the disconnected strand of wire. Moreover, when the lead is unfolded, mechanical damage is caused to the lead to be erected, and the lead which leaves the factory is unqualified due to improper labor force of workers or non-standard factory process. Constructors do not find the situation in time, after the lead is erected, under the action of large current, the resistance of the damaged part of the lead is lower than that of other parts, the heat is serious, and under the action of the large current, when the temperature reaches the melting point of the aluminum lead, strand breakage of the lead can be caused.
When the broken strand wire is repaired, three methods of sawing, re-crimping, repairing and winding are required according to different wire damage degrees. The operation method is divided into two categories of high-altitude operation and ground operation. The high-altitude operation is mainly repaired and wound. Re-crimping for sawing is good for landing operations.
Because the operation of the overhead power line faces the influence of severe natural environment, strand breakage and abrasion occur in the perennial use process, the normal operation of the line can be influenced, and certain potential safety hazards also exist. In our modern construction project, the degree of attention to the power grid construction is higher and higher, and the sustainable development of our country's economy can be promoted only by ensuring the stability and safety of the power system operation. The broken strands of the wires mainly appear near the wire hanging point and in the middle of the wires. And the difficulty of processing the middle part of the lead is the greatest. Because the overhead power line is higher than the ground, certain difficulty exists in the operation and maintenance work of the overhead power line, and the problem that the strand of the lead is broken is not easy to find in the overhauling and maintenance. If the problem of strand breakage of the wire is not processed in time, the problems of tower falling, pole falling, wire breakage and the like are possibly caused, and serious electric power safety accidents are caused.
Therefore, the invention provides a high-altitude repair device for repairing an overhead broken strand wire, which comprises a mobile device and a repair binder, when the strand breaking condition of the overhead conductors with different voltage levels is found, workers climb the tower, and put the mobile equipment on the corresponding phase position of the strand breaking conductor, the mobile equipment sends the repair binder to the specific position of the strand breaking conductor, the repair binder performs high-altitude winding repair on the strand breaking conductor, so that the mechanical and electrical properties meet the operation requirements of a power grid, because the whole repairing action is automatically completed in high altitude by adopting the mobile equipment and the repairing binder in the repairing process of the strand breaking position of the whole strand breaking lead without replacing a new lead, in addition, the traditional binding and winding repairing method that the broken strand of wire is not required to be placed on the ground in the construction process is adopted, and the broken strand of wire is erected again after binding repairing. Therefore, the overhaul time is shortened, the complicated steps of construction paying-off, wire withdrawing, wire tightening and the like are reduced, the power failure times are reduced, the fault point repairing efficiency is improved, the power of the broken strand wire is not cut off in the repairing process, and the old wire is not detached from the air.
