Description
Technical field
The utility model belongs to super (spy) high-voltage power line conductive line unfolding equipment technical field, is specifically related to a kind of high voltage and current bleeder.
Background technology
In transmission line wire unfolding work progress, often run into the situation that construction line crosses over operating band electric line.Under normal circumstances; article two, leave safe distance between circuit; construction wire is in electroless state, and induction electrostatic by the release of pay-off equipment end earthing tackle, but also can run into extreme situation in construction; as occurred to run line accident; i.e. construction line conductive contact charging operation line conductor, causes construction line wire charged, crosses over the general voltage of charging operation circuit higher (10kV ~ 500kV); if do not take safeguard measure, in line construction, the personnel of contact wire have the danger of electric shock.
In present electric transmission line hot-line line level crossing work progress, often adopt the releasing pulley of band conducting pulley, once there is the situation of running line construction line touching alive circuit, electric current can be delivered to the earth by wire, conducting pulley, earth connection, avoids causing electric shock human casualty accident.But existing wheel line tackle conductive casters with ground is coaxially arranged side by side, due to can not be completely parallel in multiple conducting wires at the same time unfolding process, therefore part conductive contact will be caused less than conductive casters, thus once there is construction line wire touching alive circuit wire accident, part current in wire cannot be released, really can not reach the effect of high voltage and current of releasing, still there is the hidden danger causing personal electric shock injures and deaths.
Utility model content
The purpose of this utility model is to provide a kind of unfolding conductor process high voltage appearance current drain device.
For achieving the above object, the utility model adopts following technical scheme:
A kind of unfolding conductor process high voltage appearance current drain device, comprise releasing pulley, the apparatus for suspension of releasing pulley both sides is respectively equipped with support, conduction wheel shaft is provided with between two supports, conduction wheel shaft is provided with conductive casters, connected by bearing between conductive casters and conduction wheel shaft, between adjacent conductive wheel, be provided with spring; Be provided with elastic rod near conductive casters shaft support, elastic rod is connected with apparatus for suspension, and apparatus for suspension is provided with limiting plate, and limiting plate is provided with through hole, is provided with the extension rod be connected with support in through hole; Described support is connected with earth connection.
Described support is connected with the unwrapping wire wheel shaft of releasing pulley.
Reduce wear during in order to draw, the centre position of described conduction wheel shaft is provided with resistance to emery wheel, is provided with spacer sleeve between resistance to emery wheel and adjacent conductive casters.Preferably, described resistance to emery wheel material is nylon.
Preferably, described spring is Different diameter spring, and the shape of Different diameter spring is that two is little broad in the middle; Described bearing is deep groove ball bearing; Described elastic rod is extension spring.
Preferably, the distance of two conductive casterses be connected by spring is 15-30mm.
The utility model structure is simple, easy to use, conductive casters can transverse shifting on conduction wheel shaft, in construction of power transmission and transformation unwrapping wire process during live across, wire contacts at any time with conductive casters, ensure that releasing of high voltage and current under precarious position, ensure more reliably for the personal safety in live across work progress provides.
