Rapid working clamp of pre-hanging type power distribution line de-icing engaged line

Abstract

The invention discloses a rapid working clamp of a pre-hanging type power distribution line de-icing engaged line, comprising a short-circuit cable, wherein the two ends of the short-circuit cable are respectively connected with lead wire hanging mechanisms; each lead wire hanging mechanism comprises a first clamping block, a second clamping block and a pull rod; the upper end of each first clamping block is movably connected with the upper end of each second clamping block; relative clamping faces of the lower end of each first clamping block and the lower end of each second clamping block are respectively provided with bayonets for hanging an overhead line; a conductive block for connecting the overhead line with the short-circuit cable is arranged at the position of the corresponding bayonet on each first clamping block or each second clamping block; the conductive block is connected with the short-circuit cable; one end of each pull rod is connected with the middle part of each second clamping block; the other end of each pull rod penetrates through the middle part of each first clamping block; and the other end of each pull rod is provided with a first locking nut. According to the rapid working clamp of the pre-hanging type power distribution line de-icing engaged line disclosed by the invention, the lead wire hanging mechanisms are respectively and additionally arranged at the two ends of the short-circuit cable to realize rapid wiring of the short-circuit cable; and the structure is simple and the utilization is convenient. The rapid working clamp is applicable to de-icing work of a power distribution line.

Description

technical field [0001] The invention relates to the field of power line equipment fittings, in particular to a quick-operation fixture for pre-hanging power transmission line melting and connecting lines. Background technique [0002] Before the present invention was proposed, DC short-circuiting was generally used for ice-melting operations, and workers were required to go to the substation in a power outage to short-circuit the overhead line and the DC power supply with a short-circuit cable. Since the ice-melting operation is carried out at high altitude and the operation requirements are higher, the operation risk is greater; at the same time, since it is necessary to install and disassemble the connection of multiple short-circuit cables and overhead wires when short-circuiting, and one short-circuit The cable needs to be manually tightened with about 6 nuts and tools such as nuts and screwdrivers are required, so the workload is heavy and time-consuming, which makes th...

Since the ice-melting operation is carried out at high altitude and the operation requirements are higher, the operation risk is greater; at the same time, since it is necessary to install and disassemble the connection of multiple short-circuit cables and overhead wires when short-circuiting, and one short-circuit The cable needs to be manually tightened with about 6 nuts and tools such as nuts and screwdrivers are required, so the workload is heavy and time-consuming, which makes the staff prone to fatigue and increases the power outage time; moreover, due to the work of the operators The environment is mostly cold and slippery, so longer working hours are likely to lead to safety accidents
