Abstract
The invention discloses an expansible multi-loop inlet wire door type pole tower. The expansible multi-loop inlet wire door type pole tower comprises cross arms, pole bodies and a ground wire support, and a wire hanging plate is arranged on the cross arms. The expansible multi-loop inlet wire door type pole tower is characterized in that the two parallel pole bodies are arranged in an equal-height mode, the ground wire support is fixedly arranged at the upper ends of the pole bodies, the number of the cross arms is three, the cross arms are fixedly connected between the upper ends of two vertical pole bodies and to the outside of the upper ends of the two pole bodies through corresponding flange plates and are on the same straight line, and re-expansible flange plates are arranged at the outer ends of the cross arms on two sides. Because the cross arms can be expanded according to needs, on the premise that pole towers are not additionally arranged, multiple-loop overhead outlet or inlet wires can be achieved through cross arm expansion, engineering cost can be reduced, construction and wire outlet mode simplification are facilitated, and safe installment is achieved; when two loops of the same tower cross, external pole towers are not needed. The expansible multi-loop inlet wire door type pole tower can be widely applied to incoming and outgoing of multiple-loop wires of a transformer substation.
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 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 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 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 diagonal member.
Described cross-arm and the distance of earth wire support are 3-5m, and the length of cross-arm is 6-9m, and external 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 external diameter is 0.7-0.9 m, and top external 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 external 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.
