According to the invention, on the basis of using an insulation boom type aerial as an insulation platform, after the power working staff wear safety devices, rapid replacement of a dual-loop linear-rod four-wire cross arm can be realized under the circumstances that working is carried out continuously with power interruption. The provided lifter has advantages of compact structure, convenient manufacturing, usage, maintenance, and portability, and high durability, reliability, and safety.

Description

Conduction wire riser

Technical field

The present invention relates to transmission of electricity modified line road service kit, especially relate to a kind of conduction wire riser not affecting electricity consumption operation.

Background technology

In electric line, double back straight line four-wire arm easily deforms or jackknifing under long-term environmental pollution and corrosion, this has buried potential safety hazard to the safe and stable operation of distribution line, have a strong impact on power supply reliability, and usually change double back straight line four-wire arm and only take power failure operation, how to overcome the impact of this unfavorable factor, solve a difficult problem of carrying out live line working, uninterrupted power supply provides reliable guarantee, client is supplied to the reliable electric energy of high-quality, increase Business Economic Benefit and social benefit, live-line replacing double back straight line four-wire arm, just seem particularly important.Do not insulating under replacing instrument at present, adopting live line working method four phase conductors cannot be mentioned simultaneously, if carry out replacing four-wire arm by force, phase fault or operating personnel likely can be caused to occur Danger Electric shock risk.Therefore researching and developing double back straight line four-wire arm instrument is problem in urgent need to solve.

Summary of the invention

For problem existing in above-mentioned prior art, the invention provides a kind of is insulated platform by aerial lift device with insulated arm, just can realize the conduction wire riser changing double back straight line four-wire arm under uninterrupted operation.

Conduction wire riser of the present invention comprises the bracket that interval is movably arranged on the bracing frame on insulation cross bar and is connected with insulation cross bar centre, in the middle of support frame as described above, there is wire casing, carrying roller is provided with in wire casing, sled block is movably set with in wire casing side, described sled block outer end has button hole, sled block the inner can swing in wire casing, described bracket lower end is connected with screw rod, described screw rod be fixed on the nut insulated in auxiliary rod and match, outer and the handle being connected with rocking bar and being connected with rocking bar of insulation auxiliary rod is stretched out in described screw rod lower end, described insulation auxiliary rod two ends are connected with back rest, back rest two ends are connected with padlock head with padlock seat respectively by chain, by padlock seat, insulation auxiliary rod can be fixed on electric pole by padlock head and chain.

Utilize conduction wire riser of the present invention, the operation of distribution network charged for replacement double back straight line pole four-wire arm be based upon tradition have a power failure change cross-arm basis on, take aerial lift device with insulated arm as insulated platform, first install on electric pole and fix conduction wire riser, after four phase conductors are placed in the bracing frame wire casing of lifter, use hand rotating rocker, rotated by screw rod, cross bar is raised, cross bar has slowly been shaken, make insulated conductor promote 0.4 meter, insulated conductor departs from insulator, then carries out replacing cross-arm.

Method of operation of the present invention

(1) correct position is selected to park aerial lift device with insulated arm, and ground connection, after carrying out sky bucket test operation, in bucket, operating personnel correctly dresses safety protective tools, enters in insulation bucket, fastens seat belts,

(2) in bucket, operating personnel operates aerial lift device with insulated arm and enters service position, does four phase conductors and earth electrode

Measure is covered in insulation,

(3) conduction wire riser is arranged on the correct position of electric pole,

(4) remove the wiring on four phase insulators, and wire is carried out all insulation cover, fixing in the wire casing utilizing sled block four phase conductors to be risen to simultaneously conduction wire riser, utilize conduction wire riser that four phase conductors are improved more than 0.4 meter, make wire leave insulator,

(5) remove old cross-arm, more renew cross-arm and the measure of insulation masked isolation is done to cross-arm, insulator,

(6) recover wire, process is contrary with (4), and carries out the measure of insulation masked isolation in time.

The present invention, for helping aerial lift device with insulated arm to be on the basis of insulated platform, after electric operating personnel safe wearing device, just can realize double back straight line pole four-wire arm quick-replaceable under uninterrupted operation.Compact conformation of the present invention, manufacture working service and easy to carry, durability, reliability and fail safe are high.
