| titleOfInvention | Deep line tightening method for small isolated gear of power transmission line |
| abstract | The invention belongs to the technical field of power transmission lines, and discloses a deep line tightening method for a small isolated gear of a power transmission line, which is characterized in that a retractable hardware fitting capable of injecting liquid is connected with a tower at one end of the isolated gear; firstly, stringing according to a released safety factor, crimping a strain clamp and hanging a strain insulator string, wherein one end of the strain insulator string is connected with a telescopic hardware fitting capable of injecting liquid on a tower, and the other end of the strain insulator string is connected with a hanging point of the tower; calculating the length L of the cable which needs to be tightened again when the cable is tightened to a normal safety coefficient; and injecting liquid into the telescopic hardware fitting to shorten the length of the telescopic hardware fitting by L. The invention avoids the construction risk of damaging the lead and the tower by over-traction, and solves the problem of unbalanced tension bearing of the smaller isolated tower gear, so that the design of the tower can not be strengthened any more, and the economical efficiency is improved. Particularly, one side of the tower, which appears in old line reconstruction engineering, is a smaller isolated gear of the original tower, so that the original tower can be prevented from being replaced, and the economic benefit is remarkable. |
