Abstract

The invention relates to the field of electrified repairing of electric line aerial conductors and especially relates to an electrified repairing method for 10kV line aerial conductors and an insulating wire lifter. The electrified repairing method is characterized by comprising the following steps: separating aerial conductors from a cross arm by virtue of a crane and the insulating wire lifter; firstly, lifting the insulating wire lifter to a position vertically above the cross arm by the crane; insulating and covering the aerial conductors by an operator after standing in an insulating bucket vehicle, and then placing the aerial conductors into an insulating hanging bracket of the insulating wire lifter one by one; erecting an insulating clamp spring of the hanging bracket, thereby preventing the aerial conductors from dropping from the insulating hanging bracket; starting the crane and slowly upward lifting the insulating wire lifter for not less than 400mm, thereby being capable of replacing the cross arm under an electrified running condition of the line. Compared with the prior art, the electrified repairing method provided by the invention has the following beneficial effects: the difficulty that a needle type insulator and a conductor cross arm cannot be replaced by utilizing the insulating bucket vehicle under an electrified condition is solved, the loss of electricity-utilizing enterprises caused by temporary power outage is reduced and the power supply reliability and the power sale quantity are greatly increased.

Description

The line device is lifted in charged restorative procedure of 10kV line frame hollow wire and insulation
Technical field
The present invention relates to the charged reparation of power circuit aerial condutor field, the line device is lifted in the restorative procedure and the insulation that relate in particular to a kind of 10kV line frame hollow wire charged for replacement electric pole cross-arm and pin insulator.
Background technology
Last century the fifties, China has started the beginning of 3.5kV distribution line live working, along with expanding economy, live line working has become the harmonious stable routine techniques means of living of socio-economic development and people that ensure.In service in electric power system; Harsh climate and outside destroy can produce enormous impact to the reliable power supply of 10kV circuit; The thunderbolt shaft tower causes pin insulator puncture, outside destroy to cause lead cross-arm metaboly to happen occasionally, and changing cross-arm and pin insulator at present has two kinds of methods:
Method one, line outage is repaired, and its shortcoming is to cause user and enterprise to have a power failure, and reduces the power supply reliability of circuit, reduces economic benefit;
Method two adopts the aerial lift device with insulated arm live line working to recover, and its shortcoming is that aerial lift device with insulated arm can receive the self load bearing effects limit, is difficult to mention aerial condutor, can't implement the operation of restringing cross-arm.
Summary of the invention
The object of the present invention is to provide a kind of charged restorative procedure of 10kV line frame hollow wire and insulation to lift the line device, solve a difficult problem of changing pin insulator and cross-arm under the charged situation, realize not having a power failure repair.
For solving the problems of the technologies described above, technical scheme of the present invention is:
The charged restorative procedure of 10kV line frame hollow wire; Lifting the line device by means of crane and insulation breaks away from aerial condutor and cross-arm; At first with crane the vertical direction position that the line device winches to cross-arm is lifted in insulation, the operator stands in the aerial lift device with insulated arm covers the back with the aerial condutor insulation and puts into the insulated gin that the line device is lifted in insulation by root, and the insulation jump ring of suspension bracket is erected; Prevent that aerial condutor from deviating from insulated gin; Start crane, gently the line device is lifted in insulation and upwards sling and be no less than the 400mm distance, can under the situation of the charged normal operation of circuit, carry out the replacing of cross-arm.
The line device is lifted in the insulation of using in the said method, comprises insulator crossarm, insulation jump ring and insulated gin, and the position of corresponding three-phase aerial condutor is respectively equipped with insulated gin on the insulator crossarm, and the opening part of insulated gin is provided with the insulation jump ring.
Said insulator crossarm is provided with two insulation boatswain chairs, and an end and the insulator crossarm of insulation boatswain chair are hinged, and the other end of insulation boatswain chair is provided with lifting hole(eyelet).
Compared with prior art; The invention has the beneficial effects as follows: having solved can't be by the difficult problem of aerial lift device with insulated arm charged for replacement pin insulator and lead cross-arm; Reduced the loss that electricity consumption enterprise caused because of temporary interruption; Not only greatly improve power supply reliability and electricity sales amount, also reduced the social contradications that produce because of temporary interruption, improved the economic benefit and the social benefit of power supply enterprise.

Embodiment
Be described further below in conjunction with the accompanying drawing specific embodiments of the invention:
See Fig. 1; Be that the present invention is insulated and lifted line device embodiment application state structural representation; This device comprises insulator crossarm 4, insulation jump ring 8 and insulated gin 6; The position of corresponding three-phase aerial condutor 7 is provided with three insulated gins 6 through insulated bolt 5 respectively on the insulator crossarm 4, and the opening part of insulated gin 6 is provided with insulation jump ring 8.Insulator crossarm 4 is provided with two insulation boatswain chairs 3, and an end and the insulator crossarm 4 of insulation boatswain chair 3 are hinged, and the other end of insulation boatswain chair 3 is provided with lifting hole(eyelet), is convenient to the crane lifting.
The present invention suffers outside destroy at electric pole 11; Cross-arm 10 deforms; Use when needing the charged for replacement cross-arm, lift the line device by means of crane and insulation lead and cross-arm are broken away from, at first the vertical direction position that the line device winches to cross-arm 10 is lifted in insulation with hoist lifting hook 1 and Insulating Hanging Belt 2; The operator stands in the aerial lift device with insulated arm covers back with aerial condutor 7 with cross-arm 10 insulation with insulating bag blanket or cross-arm insulating cover and puts into the insulated gin 6 that the line device is lifted in insulation by root; The jump ring 8 that will insulate then erects, and prevents that lead from deviating from insulated gin 6, starts crane; Gently the line device is lifted in insulation and upwards sling and be no less than the 400mm distance, can under the situation of the charged normal operation of circuit, carry out the replacing of cross-arm 10 and pin insulator 9.
This device is applicable to that aerial condutor is that horizontal mode, cross-arm 10 length are the electric pole of 2240mm.
Should prevent the electric arc casualty accident in the actual mechanical process, the operating personnel need stand on the aerial lift device with insulated arm, and the live part that the operating personnel might be touched and grounded parts insulate and cover, could guarantee operation safe, carry out smoothly.
