Description
Technical field
This utility model relates to power transmission technical field, particularly relates to a kind of double loop cable terminal station.
Background technology
Along with economic fast development, urban construction and modernization of business degree improve, the electric power as economic lifeline encounters unprecedented challenge.In order to meet power demands, in the electrical network of each big city, the proportion shared by power cable is increasing.It addition, put more effort along with urban construction, land development, high tension cable the most progressively gos deep into urban district, and in urban district, the high voltage overhead lines of present situation the most progressively implements cabling reconstructing.Limited by railway network planning and topography and geomorphology, in the case of cannot implementing pure cable run, necessarily use cable termination tower and terminal station to realize the switching of overhead transmission line and cable run.And 220kV cable run is because short-circuit electromotive force is big, circuit importance height uses cable terminal station more.But generally individually there are building or road in the both sides of existing aerial line; and building press close to Ecological rehabilitation more; as by under present situation aerial line; use traditional terminal station arrangement form; it is involved in housing demolition or road changes and moves; add the difficulty of engineering construction virtually, reduce the feasibility of engineering construction.
220kV routine double loop cable terminal station three-phase uses mode in one line, this martingale in one line is clear, and it is convenient to run, but horizontal path direction, terminal station is taken up an area wider, it is not suitable for anxiety location, corridor, especially aerial line both sides and has the location of house or highway.
Utility model content
Technical problem to be solved in the utility model, is to provide a kind of terminal station that can reduce to take up an area width, adapt to site environment needs and can improve the double loop cable terminal station of feasibility of engineering construction.
This utility model solves above-mentioned technical problem and be the technical scheme is that
This utility model provides a kind of double loop cable terminal station, and it includes the first framework, the second framework and the 3rd framework arranged along aerial line bearing of trend level, and the three-phase of the same circuit is respectively arranged on three frameworks.
As the further improvement of technique scheme, described first framework height is less than described second framework height, and described second framework height is less than described 3rd framework height.
As the further improvement of technique scheme, it is disposed with two spark gaps in the lower section of each framework, and the side of each framework deflection aerial line is disposed with two ends.
As the further improvement of technique scheme, described spark gap is arranged at the underface of the framework of correspondence.
As the further improvement of technique scheme, when the downlead length causing end from framework exceedes preset value, support insulator is architecturally set in order to fixing downlead.
As the further improvement of technique scheme, preset value is 10m.
The beneficial effects of the utility model are:
In the cable terminal station of this utility model double loop, the same circuit three-phase level is arranged on three-layer structure, and width, not as good as the half of traditional arrangement mode, is greatly reduced the occupation of land width in terminal station, it is possible to be well adapted for the needs of site environment；For providing a kind of new terminal station form under urban aerial circuit, improve the feasibility of line construction.
Accompanying drawing explanation
Fig. 1 is the plane graph of this utility model double loop cable terminal station；
Fig. 2 is the sectional drawing of this utility model double loop cable terminal station.
Detailed description of the invention
Below with reference to embodiment and accompanying drawing, the technique effect of design of the present utility model, concrete structure and generation is clearly and completely described, to be completely understood by the purpose of this utility model, feature and effect.Obviously; described embodiment is a part of embodiment of the present utility model rather than whole embodiment, based on embodiment of the present utility model; other embodiments that those skilled in the art is obtained on the premise of not paying creative work, belong to the scope of this utility model protection.It addition, all connection/annexations related in patent, the most singly refer to that component directly connects, and refer to couple auxiliary according to being embodied as situation by adding or reducing, form more excellent draw bail.Each technical characteristic in this utility model, can be with combination of interactions on the premise of the most conflicting conflict.
Please with reference to Fig. 1 and Fig. 2, this utility model double loop cable terminal station includes the first framework the 1, second framework 2 and the 3rd framework 3 arranged along aerial line 7 bearing of trend level, and the width of framework is preferably set to 11m.The three-phase of the same circuit is respectively arranged on three frameworks, and in other words, on each framework, hanging wire is biphase.Use single-side inlet, one side to draw under type, be not provided with any off device and grounding apparatus.
In order to ensure enough electrical distances, it is preferable that the height of the first framework 1 is less than the height of the second framework 2, and the height of the second framework 2 is less than the height of the 3rd framework 3.
It is disposed with two spark gaps 4 in the underface of each framework, and the side of each framework deflection aerial line 7 is disposed with two ends 5.Specifically, end 5 is about 2.5m with corresponding framework centre-to-centre spacing；It is spaced about 5m between the end 5 of different circuit；3rd framework 3 and the second framework 2 are about 7.5m apart from about 8.5m, the distance of the second framework 2 and the first framework 1.
When downlead 8 length causing end from framework exceedes preset value, support insulator 6 is architecturally set in order to fixing downlead 8, preset value can be arranged flexibly according to actual condition of construction, this preset value is set to 10m by the present embodiment, namely when downlead 8 is more than 10m, setting support insulator 6 at ground 10m at framework to fix, prevent downlead 8 long, conductor vibration acutely causes end connecting plate to loosen.
A, B, C three-phase level of the same circuit is arranged on three-layer structure, is greatly reduced terminal station and takes up an area width, improves the feasibility of line construction；When being more suitable for urban aerial track remodelling, restricted width location；The three-phase line of terminal station and terminal tower is arranged vertically, not Existential Space transfer problem, and wire spacing is easier to control, and the span in terminal tower and terminal station does not exist restriction, can closely can be remote.
It is above preferred embodiment of the present utility model is illustrated, but this utility model is not limited to described embodiment, those of ordinary skill in the art it may also be made that all equivalent variations or replacement on the premise of this utility model spirit, and deformation or the replacement of these equivalents are all contained in the application claim limited range.
