Abstract

Provided is a ratchet wheel type combined tool for fastening a jumper conductor clamp in a charged mode. The ratchet wheel type combined tool comprises a ratchet wheel wrench (5), a connection assembly and an insulation operation rod (1), wherein the ratchet wheel wrench (5) is formed by the mode that one end of a handle (4) is connected with an open type nut wrench (4.1) and the other end of the handle (4) is connected with a closed type ratchet wheel wrench (4.2); the connection assembly is composed of a clamp, a penetrating bolt (3.1) connected to one side of the clamp, and a nut (3.2). The ratchet wheel type combined tool has the advantage that the shortcomings of one-way tension resisting jumper conductor clamp indirect operation and heating of a charged jumper conductor clamp of an overhead transmission line in the same tower multi-circuit vertical arrangement mode are overcome. The tool is used for overcoming the heating defect of the charged jumper conductor clamp, investment of operation personnel and tools is reduced, operation intensity and operation risk of the operation personnel are lowered, efficiency is improved, cost is lowered, the electric reliability is improved, and the number of times of power failure is reduced.

Description

technical field [0001] The invention belongs to the live inspection and maintenance of transmission lines, especially the live treatment maintenance tool structure technology for the indirect operation of the heating of the drainage wire clamp of the single-circuit tension tower (rod) and the heating defect of the overhead transmission line drainage wire clamp of the same tower with multiple vertical arrangements. field. Background technique [0002] With the rapid development of the economy and the continuous expansion of the scale of the power grid, the number of overhead transmission lines increases, and the load of the transmission line increases. Especially after the bolts of the drainage clamps are loosened, more and more defects are caused by the heating of the drainage clamps. ; To improve the reliability of power supply, the power supply enterprise must optimize the treatment method for eliminating the heating defect of the drain wire clamp when it is live. At pres...
