π route is by a relatively simple for cable road, finds suitable open loop point position, transition joint is made, for overhead line
Generally there are these three patterns of the double π of single receipt π, double back list π, double back on road.In current transmission line of electricity, π technology generally uses 2-3 base
Terminal shaft tower is achieved, and list π will form a triangular form sometimes after the completion of double back transmission line is implemented, and double π situations are according to opening
The position difference of circling point will form two line corridors, though technical solution is more mature, on the ground that land resource is more nervous
Area, newly-built 2-3 base shaft tower not only put into big and occupy large amount of land resources.
Summary of the invention
The purpose of the present invention is to provide a kind of open loop towers, are carrying out only needing newly-built 1 base shaft when π connects transformation to transmission line of electricity
Tower not only puts into small also can be reduced and occupies soil.
Realizing the technical solution of the object of the invention is: a kind of open loop tower, including shaft tower ontology, it is characterised in that: along shaft tower
Ontology is provided with ground wire cross-arm, the first conducting wire cross-arm, the second conducting wire cross-arm and privates cross-arm, the ground wire from top to bottom
Cross-arm, the first conducting wire cross-arm, the second conducting wire cross-arm and privates cross-arm arrangement in Y-shape.
And ground wire cross-arm, the first conducting wire cross-arm, the second conducting wire cross-arm and the privates cross-arm by three with shaft tower
Ontology is that the cross-arm body of center of circle arrangement in Y-shape forms, and the cross-arm body is connect by two connectors with shaft tower ontology.
And two connectors are the stiffened panels of a pair of of parallel arrangement, described stiffened panel one end and shaft tower ontology connect
It connects the other end to extend to outside shaft tower ontology, the inside of the stiffened panel and the two sides of cross-arm body all have a series of corresponding
Installation hole location, there is bolt to pass through from above-mentioned installation hole location and connect stiffened panel with cross-arm body.
And described outwardly extending one end of cross-arm body is equipped with strain insulator-string thread gripping-board and jumper string thread gripping-board.
And the lateral length of the second conducting wire cross-arm is greater than the lateral length of first, privates cross-arm, and it is described
Ground wire cross-arm lateral length less than the first, lateral length of privates cross-arm.
The present invention has the advantages that comparing conventional open-loop carrying out only creating 1 base shaft tower when π connects transformation to transmission line of electricity
Scheme reduces 1 base of shaft tower, reduces the project amount of shaft tower and basis, and has saved line corridor channel, saves construction investment.

Specific embodiment
Referring to Fig. 1~7, below with reference to embodiment, the present invention will be further described.
The present invention relates to electric power line pole tower field, especially a kind of open loop tower, including shaft tower ontology 1, it is characterised in that:
It is provided with ground wire cross-arm 2, the first conducting wire cross-arm 3, the second conducting wire cross-arm 4 and privates cross-arm from top to bottom along shaft tower ontology 1
5, the ground wire cross-arm 1, the first conducting wire cross-arm 2, the second conducting wire cross-arm 3 and the arrangement in Y-shape of privates cross-arm 4.
The unilateral open loop that 1 base shaft tower is achieved that route has only been created using the design scheme, has compared conventional open-loop scheme
1 base of shaft tower is reduced, the project amount of shaft tower and basis is reduced, and has saved line corridor channel, saves construction investment.
And ground wire cross-arm 1, the first conducting wire cross-arm 2, the second conducting wire cross-arm 3 and the privates cross-arm 4 is by three
Root is formed with the cross-arm body 7 that shaft tower ontology 1 is center of circle arrangement in Y-shape, and the cross-arm body 7 passes through two connectors and bar
Tower ontology 1 connects.
Cross-arm body 7 is connect by two connectors with shaft tower ontology 1, stabilized structure.
Further technical solution can be the stiffened panel 6 that two connectors are a pair of of parallel arrangements, and described adds
6 one end of gusset connect the other end with shaft tower ontology 1 and extends to outside shaft tower ontology 1, the inside of the stiffened panel 6 and cross-arm body
7 two sides all have a series of corresponding installation hole locations, have bolt to pass through from above-mentioned installation hole location and by stiffened panel 6 and horizontal
Ontology 7 is carried on a shoulder pole to connect.
The inside of stiffened panel 6 and the two sides of cross-arm body 7 all have a series of corresponding installation hole locations, and when installation will be horizontal
The installation hole location for carrying on a shoulder pole 7 two sides of ontology is aligned with the installation hole location of two stiffened panels, 6 inside, has bolt to pass through from above-mentioned installation hole location
And it connects.
And described outwardly extending one end of cross-arm body 7 is equipped with strain insulator-string thread gripping-board 8 and jumper string thread gripping-board 9.
Strain insulator-string thread gripping-board 8 and jumper string thread gripping-board 9 are for hanging fitting.
The lateral length that further technical solution is also possible to the second conducting wire cross-arm 3, which is greater than first, third, leads
