Abstract
The invention discloses and can expand multiloop inlet wire H-frame pole tower, comprise cross-arm, shaft and earth wire support, on cross-arm, be provided with thread gripping-board, it is characterized in that: described shaft is parallel, and contour be provided with two, is fixed with earth wire support in the upper end of two shafts; Described cross-arm is provided with three, respectively by corresponding ring flange be fixedly connected on two plumbing bars hold with it between and the upper end outside of two shafts, and three cross-arms are point-blank; Be provided with and expand again ring flange in the cross-arm outer end of both sides. This can expand multiloop inlet wire H-frame pole tower, because cross-arm can be expanded as required, so can be in the situation that not setting up shaft tower, expand and realize many times overhead outlets or inlet wire by cross-arm, can reduce construction costs, constructability, outlet method simplification, and safety, in the time that common-tower double-return crossing elimination is crossed over, do not need additionally to add shaft tower. Can be widely used in the line of transformer station's multi circuit transmission lines.
Description
Technical field
The present invention relates to the improvement of a kind of transformer station cable incoming-outgoing wire shaft tower, specifically one can be expanded multiloop inlet wire H-frame pole tower.
Background technology
Present stage, the power construction of national basis facility, high-voltage fence is along with expanding economy, and also fast development is got up. For dwindling transformer station's floor space and saving circuit corridor, transformer station adopts cable incoming-outgoing wire mostly; In city, require power circuit in underground laying, to transformer station, enter transformer station by shaft tower overhead power line again. Outside transformer station, conventional shaft tower is mostly double-circuit line shaft tower or single back line shaft tower at present, comprises that tower body and cross-arm form, and cross-arm is erected at the both sides of tower body upper end, is carried wire weight and is met electrical distance requirement by the cross-arm of both sides. The deficiency of this shaft tower is: the one, cannot take into account many times overhead outlets or inlet wire in transformer station outside; The 2nd, shaft tower is arranged more, and after a base tower erection completes, cannot expand, if think the newly-built base shaft tower again of outlet again, has increased construction investment, and has caused waste. Known by retrieving, have not yet to see in the situation that not setting up shaft tower, expand the report of the shaft tower of realizing many times overhead outlets or inlet wire by cross-arm.
Summary of the invention
The object of the present invention is to provide a kind ofly in the situation that not setting up shaft tower, expand and realize many times overhead outlets or inlet wire by cross-arm, reduce construction costs, constructability, outlet method and simplify, and the multiloop expanded of structural safety inlet wire H-frame pole tower.
In order to reach above object, the technical solution adopted in the present invention is: this can expand multiloop inlet wire H-frame pole tower, comprise cross-arm, shaft and earth wire support, be provided with three thread gripping-boards of equidistant arrangement at cross-arm sidewall, it is characterized in that: described shaft is parallel, and contour be provided with two, earth wire support is fixed in upper end at two shafts by corresponding ring flange, make two shafts and an earth wire support composition door shape; Described cross-arm is provided with three, be fixedly connected between two shaft upper ends by corresponding ring flange respectively and the outside of the upper end of two shafts, and three cross-arms is point-blank, and parallel with earth wire support; Be provided with and expand again ring flange in the cross-arm outer end of both sides.
The present invention also implements by following measure: described cross-arm is fixedly connected with shaft by brace.
Described cross-arm and the distance of earth wire support are 3-5m, and the length of cross-arm is 6-9m, and overall diameter is 0.2-0.3m, and its length and wire spacing can be determined according to electric pressure adjustment; The height of described shaft is 13-17m, and bottom overall diameter is 0.7-0.9m, and top overall diameter is 0.4-0.5m, can adjust as required.
Described shaft adopts the Q345B steel plate coiling that thickness is 8mm to be welded, and is Taper Pipe shape.
It is that the Q345B steel plate of 8mm is made tubulose that described cross-arm and earth wire support all adopt thickness; The overall diameter of earth wire support is 0.1-0.2m.
Beneficial effect of the present invention is: this can expand multiloop inlet wire H-frame pole tower, because cross-arm can be expanded as required, so can be in the situation that not setting up shaft tower, expand and realize many times overhead outlets or inlet wire by cross-arm, can reduce construction costs, constructability, outlet method simplification, and structural safety, in the time that common-tower double-return crossing elimination is crossed over, do not need additionally to increase shaft tower and take corridor. Can be widely used in the line of transformer station's multi circuit transmission lines.

Fig. 1 is that structure master of the present invention looks schematic diagram.
In figure: 1, cross-arm; 2, shaft; 3, earth wire support; 4, ring flange; 5, expand again ring flange; 6, thread gripping-board; 7, brace.
Detailed description of the invention
Make the present invention with reference to Fig. 1. This can expand multiloop inlet wire H-frame pole tower, comprise cross-arm 1, shaft 2 and earth wire support 3, be provided with three thread gripping-boards 6 of equidistant arrangement at cross-arm 1 sidewall, it is characterized in that: described shaft 2 is parallel, and contour be provided with two, earth wire support 3 is fixed in upper end at two shafts 2 by corresponding ring flange, make two shafts 2 and earth wire support 3 composition door shapes; Described cross-arm 1 is provided with three, be fixedly connected between two shaft 2 upper ends by corresponding ring flange 4 respectively and the outside of the upper end of two shafts 2, and three cross-arms 1 is point-blank, and parallel with earth wire support 3; Be provided with and expand again ring flange 5 in cross-arm 1 outer end of both sides, can connect identical shaft 2 and cross-arm 1 to external expansion again by expanding again ring flange 5, to meet the expansion demand of many times overhead outlets or inlet wire.
As improvement of the present invention: the upper wall of described cross-arm 1 is fixedly connected with shaft 2 by brace 7, to improve the bearing capacity of cross-arm 1.
Described cross-arm 1 is 3-5m with the distance of earth wire support 3, and the length of cross-arm 1 is 6-9m, and overall diameter is 0.2-0.3m, and its length and wire spacing can be determined according to electric pressure adjustment; The height of described shaft 2 is 13-17m, and bottom overall diameter is 0.7-0.9m, and top overall diameter is 0.4-0.5m, can adjust as required.
It is that the Q345B steel plate coiling of 8mm is welded that described shaft 2 adopts thickness, is Taper Pipe shape, so that install and transport; Meanwhile, adopt taper steel pipe, institute's floor space is little, and structure is attractive in appearance, can be used for level land, urban district etc.
It is that the Q345B steel plate of 8mm is made tubulose that described cross-arm 1 and earth wire support 3 all adopt thickness; The overall diameter of earth wire support 3 is 0.1-0.2m.
Use the present invention constantly, stand on transformer station's outgoing line side by of the present invention group, connect by strain insulator, make that transformer station's line is unified, planning.
