Abstract
The invention discloses a 110KV power line double-circuit linear double-T connection tower. The 110KV power line double-circuit linear double-T connection tower comprises a tower and at least three transverse crossarms positioned on the tower; at least three longitudinal crossarms are arranged on the tower; the transverse crossarms and the longitudinal crossarms are staggered and vertical to each other; in each circuit, a node A positioned at the left end of each of the transverse crossarms is connected to a node C positioned at the rear end of each of the longitudinal crossarms, and the node C positioned at the rear end of each of the longitudinal crossarms is connected with an output circuit; and a node B positioned at the right end of each of the transverse crossarms is connected to a node D positioned at the front end of each of the longitudinal crossarms, and the node D positioned at the front end of each of the longitudinal crossarms is connected with the output circuit. By adopting the technical scheme, the problem that the tower occupies land can be solved at the absence of a planned line passageway, a large sum of power construction fund can be saved for a construction unit, the economic and technical effects are remarkable, and favorable conditions can be created for a power line entering a busy downtown in a double-circuit overhead T connection manner.
Description
Technical field
The present invention relates to the electric power tower in a kind of transmission line of electricity, specifically relate to a kind of electric power tower of using when two T of returning connect of in 110kV transmission of electricity double-circuit line, carrying out.
Background technology
110kV double loop double T connects the sections tower and can thoroughly solve two the return Ts of 110kV transmission line of electricity under specific landform and special corridor situation and connect; Can save a large amount of shaft towers and take up an area of and track investment, create conditions for two times built on stilts T of transmission line of electricity tap into bustling business district.
Electric equipment compartment is apart from difficult assurance when connecing owing to carry out double T on the iron tower of double loop, and the double loop double T that also not have in the prior art to finalize the design connects the type tower.Along with the continuous reinforcement of urban distribution network framework, most of city has planned that a 110kV ultra-high-tension power transmission line directly delivers to the urban district, and to connect the sections tower extremely urgent so develop a kind of double loop double T.
Summary of the invention
The purpose of this invention is to provide the two straight line double Ts of returning of a kind of 110KV transmission line of electricity simple in structure and connect tower.
For achieving the above object, the present invention is by the following technical solutions:
The present invention includes shaft tower and be positioned at least three horizontal cross-arms on the shaft tower, also be provided with at least three vertical cross-arms on the described shaft tower, described horizontal cross-arm and the vertically staggered and vertical setting of cross-arm; In every phase loop, the node A that is positioned at horizontal cross-arm left part is connected to the node C of vertical cross-arm rearward end, by the node C connection output loop of vertical cross-arm rearward end; The node B that is positioned at horizontal cross-arm right part is connected to the node D of vertical cross-arm leading section, by the node D connection output loop of vertical cross-arm leading section.
Three horizontal cross-arms and three vertical cross-arms are set, laterally cross-arm and the vertically staggered and vertical setting of cross-arm on described shaft tower; And the top of shaft tower is vertical cross-arm.
In every phase loop, the employing drainage thread carries out the connection between the node.
Adopt the present invention of technique scheme, can lack under the situation of planning circuit corridor, solve shaft tower occupation of land problem, can save a large amount of power construction funds for Construction unit, economy and obvious technical effects have been created advantage for two times built on stilts T of transmission line of electricity tap into bustling business district.
Description of drawings
Fig. 1 is a front view of the present invention;
Fig. 2 is a vertical view of the present invention.
The specific embodiment
As shown in Figure 1 and Figure 2, present embodiment is made of shaft tower 7 and the vertical cross-arms 2,4,6 of 1,3,5 and three of three horizontal cross-arms that are positioned on the shaft tower 7, wherein, laterally cross-arm and vertically cross-arm interlock and vertical setting, and the top of shaft tower 7 is vertical cross-arm 2.
For A phase loop, the node A1 that is positioned at horizontal cross-arm 1 left part is connected to the node C1 of vertical cross-arm 2 rearward end, by the node C1 connection output loop E of vertical cross-arm 2 rearward end; In addition, the node B1 that is positioned at horizontal cross-arm 1 right part is connected to the node D1 of vertical cross-arm 2 leading sections, by the node D1 connection output loop E of vertical cross-arm 2 leading sections.Thus, can form the mutually double-T shaped loop of A.
In like manner, for B phase loop, the node A2 that is positioned at horizontal cross-arm 3 left parts is connected to the node C2 of vertical cross-arm 4 rearward end, by the node C2 connection output loop E of vertical cross-arm 4 rearward end; In addition, the node B2 that is positioned at horizontal cross-arm 3 right parts is connected to the node D2 of vertical cross-arm 4 leading sections, by the node D2 connection output loop E of vertical cross-arm 4 leading sections.Thus, can form the mutually double-T shaped loop of B.
For C phase loop, the node A3 that is positioned at horizontal cross-arm 5 left parts is connected to the node C3 of vertical cross-arm 6 rearward end, by the node C3 connection output loop E of vertical cross-arm 6 rearward end; In addition, the node B3 that is positioned at horizontal cross-arm 5 right parts is connected to the node D3 of vertical cross-arm 6 leading sections, by the node D3 connection output loop E of vertical cross-arm 6 leading sections.Thus, can form the mutually double-T shaped loop of C.
Need to prove that in every phase loop, all adopt drainage thread to carry out connection between the node, the connected mode of its drainage thread is a technology well known to those of ordinary skill in the art.
In addition, when having the neutral conductor in the loop, can set up a horizontal cross-arm and a vertical cross-arm on shaft tower 7, its catenation principle and A, B, C are mutually identical.
