Abstract
The invention discloses a method of replacing strain poles without laying down lines. The method includes the steps of 1, powering off the lines, using a double-hook strainer to connect angle steel link plates connected with same-phase wires on two sides of a strain pole; 2, removing cross arms from the strain pole and suspending the double-hook strainer and the wires on the side wires connected with the same; 3, lifting out the strain pole with a crane, and setting up a new strain pole; 4, re-connecting the lines to the new strain pole, and removing the double-hook strainer. The angle steel link plates are connectors connected between the cross arms of the strain pole and the wires. The method has the advantages that workload is reduced, fewer workers are required and replacing time is shortened.
Description
Technical field
The present invention relates to a kind of not line of fall and change strain resistant electric pole method.
Background technology
In rural power grids line upkeep, 10kv or 400v circuit much set up along roadside, often run into that shaft tower is broken by vehicle or because of the aging even phenomenon of rupture of crackle that occurs, the particularly circuit of two different directions scissors crossing on same electric pole, once this electric pole needs to change, by universal experience, wire need be taken off in this electric pole place strain section, remove gold utensil on bar, both sides wire drops down onto ground, fastening both sides wire and circuit, extract impaired electric pole, plants vertical new bar, recover gold utensil wire, recover power transmission.The method of work of this replacing electric pole not only causes customer outage hours long, and workload is large and to take people many.
Summary of the invention
The object of this invention is to provide a kind of not line of fall replacing strain resistant electric pole method that reduces workload, reduces a staff, shortens the replacing time.
For achieving the above object, the present invention adopts following technical scheme: the line of fall is not changed strain resistant electric pole method, comprise the steps: (one) line outage, the angle bar yoke plate that tension-resistant rod both sides connected separately with phase conductor with double hook stretcher links together, angle bar yoke plate is to be connected to the connector between cross-arm and wire on tension-resistant rod, (2) remove the cross-arm on tension-resistant rod, make the both sides wire of double hook stretcher and connection thereof in vacant state, (3) with crane, tension-resistant rod is hung out, plant again vertical new tension-resistant rod, (4) recover the connection of both sides wire on new tension-resistant rod, and remove double hook stretcher.
The not line of fall of the present invention is changed strain resistant electric pole method, and its beneficial effect is: reduce workload, reduce a staff, shorten the replacing time.

Embodiment
The line of fall is not changed strain resistant electric pole method, described tension-resistant rod 6 is strain resistant electric pole, before tension-resistant rod 6 is changed, as shown in Figure 1, wire 1 connecting insulator 2 of tension-resistant rod 6 sides, insulator 2 is connecting angle iron yoke plate 3 again, angle bar yoke plate 3 is connected on the cross-arm 4 of tension-resistant rod 6 again, the wire 1 that is tension-resistant rod 6 sides passes through connecting insulator 2 successively, angle bar yoke plate 3 and cross-arm 4 are connected on tension-resistant rod 6, angle bar yoke plate 3 is for being connected to the connector between cross-arm 4 and wire 1 on tension-resistant rod 6, cross-arm 4 is for being fastened on the securing member on tension-resistant rod 6, the wire 1 of tension-resistant rod 6 both sides homophases forms path by central conductor 5 again, the method of attachment of tension-resistant rod 6 and side wire 1, and the annexation between tension-resistant rod 6 both sides wires 1, cross-arm 4, angle bar yoke plate 3, insulator 2 is prior art, therefore do not describe in detail, when tension-resistant rod 6 is changed, comprise the steps: (one) as shown in Figure 2, line outage, with the angle bar yoke plate 3 that double hook stretcher 8 connected tension-resistant rod 6 both sides separately with phase conductor 1, link together, double hook stretcher 8 is provided with hook adjustable length to carry out the instrument of tensioning adjusting for two, double hook stretcher 8 is prior art, therefore do not describe in detail, the hook at double hook stretcher 8 two ends is hooked in respectively on two angle bar yoke plates 3, certainly, on angle bar yoke plate 3, the hook of corresponding double hook stretcher 8 is provided with dog hole, (2) as shown in Figure 3, remove the cross-arm 4 on tension-resistant rod 6, now there is double hook stretcher 8 to connect both sides wire 1 by two angle bar yoke plates 3, the both sides wire 1 that makes double hook stretcher 8 and connect is in vacant state, complete the separated of wire 1 and tension-resistant rod 6, do not affect line security, (3) at tension-resistant rod 6, by the place of burying, loosened the soil, with crane, tension-resistant rod 6 is hung out, plant again vertical new tension-resistant rod 6A, now as shown in Figure 4, (4) as shown in Figure 5, recover the connection of both sides wire 1 on new tension-resistant rod 6A, being about to cross-arm 4 gold utensils such as grade is reinstalled on new tension-resistant rod 6A, two angle bar yoke plates 3 of both sides wire 1 are connected with cross-arm 4 respectively, remove again double hook stretcher 8.Now should notice that new tension-resistant rod 6A buried depth and technique meet standard.Then adjust wire 1 sag, recover transmission operation.It is example that the present embodiment accompanying drawing only be take the both sides wire of a phase, and other wire principles are identical, therefore do not illustrate in the drawings.
The not line of fall of the present invention is changed strain resistant electric pole method, is the construction method of being convenient to former impaired tension-resistant rod 6 to be replaced with new tension-resistant rod 6A, can reduce workload, reduce a staff, shortens the replacing time.
Claims (1)
1. the line of fall is not changed strain resistant electric pole method, it is characterized in that: comprise the steps: (one) line outage, the angle bar yoke plate that tension-resistant rod both sides connected separately with phase conductor with double hook stretcher links together, angle bar yoke plate is to be connected to the connector between cross-arm and wire on tension-resistant rod, (2) remove the cross-arm on tension-resistant rod, make the both sides wire of double hook stretcher and connection thereof in vacant state, (3) with crane, tension-resistant rod is hung out, plant again vertical new tension-resistant rod, (4) recover the connection of both sides wire on new tension-resistant rod, and remove double hook stretcher.
