Description
Technical field
The invention belongs to power industry, the specific purpose tool technical field of a kind of power failure or charged for replacement 220kV conductor spacer.
Background technology
On ultra-high-tension power transmission line, in order to reduce conductor corona electric discharge and the interference to communication, generally adopt bundle conductor.At present, the power transmission line of 220kV adopts double bundle conductor.In order to ensure that double bundle conductor wire harness spacing remains unchanged to meet electric property, reduce surface voltage gradient, and in a short-circuit situation, unlikely generation electromagnetic force between wire harness, cause the collision that attracts each other, though or cause the attraction collision of moment, accident can return to normal condition after eliminating, and thus separated by a distancely in span has installed conductor spacer.Double bundle conductor design pitch is 0.4m, and namely the installation length of conductor spacer is also 0.4m.
When conductor spacer on double bundle conductor is owing to installing originally, bolted is not in place or be in operation and be subject to the impacts such as conductor vibration for a long time, there will be the defect that loosening, damage etc. threatens line security to run.As processed not in time, conductor spacer long term wear wire will cause the major accidents such as broken string, bar.Have a power failure or charged installation, change conductor spacer and become a routine work of power transmission lines overhauling.
Charged for replacement or when installing new conductor spacer additional, employing be soft ladder busywork method.Rope ladder is suspended on a root wire, and when operating personnel arrives equipotential installation site by climbing rope ladder, the weight self adding rope ladder will make two root wires pull open larger distance up and down.If the distance of two root wires can not be remained on 0.4m, operating personnel cannot change, install new conductor spacer.The method in the past adopted is throwing empire silk rope, and empire silk rope was thrown the sub-conductor of eminence by the personnel on wire, after making the spacing of two root wires roughly reach 0.4m, fixes with the colligation of empire silk rope by pulling.This kind of method defect is obvious: 1. there is larger uncertainty, the method success rate of throwing empire silk rope is low, has that wind weather is more difficult to be completed; 2. throwing empire silk rope, stator wire duration, operating personnel's physical consumption is large, and whole maintenance process exists greater risk.Therefore, invent if can design and a kind ofly convenient and swiftly drag back sub-conductor and the distance of two root wires can be fixed on the specific purpose tool of 0.4m, operating personnel just saferly can complete power failure or charged installation efficiently, change the service work of conductor spacer.
Summary of the invention
In order to overcome defect that above-mentioned prior art exists, the energy designed is convenient and swift just drags back sub-conductor and the distance of two root wires can be fixed on a kind of power failure of 0.4m or the specific purpose tool of charged for replacement 220kV conductor spacer for object of the present invention.
The object of the invention is to realize by following technical solution.
A specific purpose tool for power failure or charged for replacement 220kV conductor spacer, is characterized in that, comprises one and rises to the bait and a lower hook, be connected respectively between upper and lower hook by a laborsaving screw mandrel with its threaded engagement; Rising to the bait, the chimoto of lower hook is connected to a trigger-type locking hook, and after trigger equipment triggers, locking device pins trigger-type locking hook, make to rise to the bait, lower hook closed with trigger-type locking hook respectively after forms a round structure; Rising to the bait, side is fixedly connected with pulley, is fixedly connected with insulating bar connector, fixes screw mandrel by screw mandrel locking device in lower hook side.
Beneficial effect
The present invention can solve problems such as changing conductor spacer operational method complex steps in the past, the activity duration is long, working strength is large, operating risk is high, substantially increase operating efficiency, enhance the fail safe of maintainer's work, make the upkeep operation standardization more of power failure or charged for replacement 220kV conductor spacer, standardization.
