Description
Technical field
When the present invention relates to a kind of multiple-circuit on same tower transformation, the processing method having a power failure during the difference of two lines road, it is a kind of processing method avoiding two lines road simultaneously to have a power failure, belongs to power supply unit technical field, a kind of multiple-circuit on same tower construction method of relocating during power down mode when difference.
Background technology
In the national basis facility power construction of present stage, high-voltage fence is along with expanding economy, and also fast development is got up.Dotted electrical network is interspersed in big ground, and line corridor is more nervous, gets more and more with shaft tower double loop, multi circuit transmission lines.To same shaft tower double-circuit line, the two-way power supply of the most same transformer station, for avoiding affecting enterprise's production and resident's daily life, two lines road can not have a power failure simultaneously.Owing to being affected by local plan and urban development, power circuit much needs to transform, current multiple-circuit on same tower is relocated when constructing, must carry out under power-off condition, then carry out organizing tower and putting stringing below original circuit, this production that certainly will affect periphery enterprise and the daily life of resident.If considering again to set up a road temporary source, the then former circuit of further conversion to this transformer station, one is that cost is at a relatively high, is far longer than the cost that double-circuit line has a power failure；Two is that plant-grid connection system need to be examined, and examines and the erection time is the longest；The most again a road temporary source is set up inadvisable.
By retrieval, have not yet to see in multiple-circuit on same tower transformation process, during the difference of two lines road, under power down mode, carry out the report constructed of relocating.
Summary of the invention
It is an object of the invention to provide a kind of in multiple-circuit on same tower, when transformer station does not has a power failure, ensure user's normal electricity consumption, by increasing interim shaft tower, realize double-circuit line to have a power failure by stages, finally make transmission line of electricity walk around the multiple-circuit on same tower of building construction method of relocating when difference during power down mode.
In order to reach object above, the technical solution adopted in the present invention is: this multiple-circuit on same tower construction method of relocating during power down mode when difference, including a former shaft tower, No. two former shaft towers, a transmission line of electricity and No. two transmission lines of electricity, a transmission line of electricity and No. two transmission lines of electricity it are designed with on a number former shaft tower and No. two former shaft towers, it is provided with building between a number former shaft tower and No. two former shaft towers, it is characterised in that: it has comprised the following steps:
(1), a transmission line of electricity has a power failure, No. two normal power transmissions of transmission line of electricity, a number interim shaft tower, No. two new shaft towers, No. three new shaft towers and No. two interim shaft towers are set between a former shaft tower and No. two former shaft towers, change into a transmission line of electricity between a former shaft tower and No. two former shaft towers setting up on an interim shaft tower, No. two new shaft towers, No. three new shaft towers and No. two interim shaft towers；
(2), No. two transmission lines of electricity have a power failure, a number transmission line of electricity power transmission, a number new shaft tower and No. four new shaft towers are set between a former shaft tower and No. two former shaft towers, change into No. two transmission lines of electricity between a former shaft tower and No. two former shaft towers setting up on a new shaft tower, No. two new shaft towers, No. three new shaft towers and No. four new shaft towers；And whole former circuits in the range of demolition of buildings；
(3), No. two transmission line of electricity power transmissions, a number transmission line of electricity has a power failure, remove an interim shaft tower and No. two interim shaft towers, and change into setting up on a new shaft tower by a transmission line of electricity between a former shaft tower and No. two new shaft towers, meanwhile, a transmission line of electricity between No. two former shaft towers and No. three new shaft towers changes into setting up on No. four new shaft towers；
(4), a transmission line of electricity power transmission, construction of relocating completes.
A described interim shaft tower and No. two interim shaft towers use angle tower, and the concrete corner number of degrees are depending on practical situation, and cross-arm uses arranged vertically；Shaft tower shaft is positioned at outside circuit, and cross-arm conducting wire hanging point is consistent with the circuit relocated, and the basic scope of new frame tower avoided by shaft tower.
The beneficial effects of the present invention is: in multiple-circuit on same tower, by increasing interim shaft tower, realize double-circuit line to have a power failure by stages, transmission line of electricity is finally made to walk around building, the most interim repeatable utilization of shaft tower, in the case of not increasing construction investment, it is achieved that has a power failure during multiple-circuit on same tower difference, ensure during track remodelling, do not interfere with enterprise and produce and resident's daily life.
