A kind of cable termination with cross over crane span structure integral type tower
【Technical field】
The present invention relates to ultra-high-tension power transmission line technical field, especially a kind of terminal and crane span structure integrated cable crossover tower.
【Background technology】
With national economy fast development, overhead transmission line is with cable run using increasingly popular in engineering.Overhead transmission line
It is set up in ground or more, is influenced by site environment, exists and builds the deficiencies of difficulty is big, civil problem is more, influence landscaping;Electricity
Cable line arrangement is frequently located in below ground, is influenced by landform, pipeline etc., and huge, pipeline evacuation difficulty etc. that there are construction costs is no
Foot.
It in urban area, the case where intersection for same Xia Chuan highways, is influenced, is created by overhead transmission line and cable run limitation
Overhead transmission line influences beauty, and the newly-built embedded deep difficulty of construction of cable run is big, it is therefore proposed that a kind of terminal is electric with crane span structure integral type
Cable crossover tower completes line crossing cabling using portal structure.
【Invention content】
The main purpose of the present invention is to provide a kind of cable terminations with across crane span structure integral type tower, utilizes tower body structure
Force-bearing characteristics, which are set up, crosses over crane span structure, and highway alignment leap is worn under realization, effectively avoids barrier, and reduction construction cost, construction are difficult
Degree and building time, do not influence overall beautiful.
To achieve the above object, the technical solution that the present invention takes is:
A kind of cable termination with cross over crane span structure integral type tower, it is made of two terminal units and a crane span structure unit, end
End identical element is located at crane span structure unit both sides, and the terminal unit includes tower body, ground wire cross-arm, topping wire cross-arm, middle layer conductor
Cross-arm, auxiliary cross-arm, foretells font cable termination, cable at lower layer conductor cross-arm;
The ground wire cross-arm, topping wire cross-arm, middle layer conductor cross-arm, lower layer conductor cross-arm, auxiliary cross-arm are located at tower body
On be arranged from top to bottom, both sides cross-arm is arranged in every layer of cross-arm horizontal path direction;
The ground wire cross-arm taper fixes ground wire, and topping wire cross-arm, middle layer conductor cross-arm, lower layer conductor cross-arm taper are solid
Determine conducting wire, taper, which is fixed, between topping wire cross-arm, middle layer conductor cross-arm, lower layer conductor cross-arm and auxiliary cross-arm foretells font cable
Terminal;
The crane span structure unit is made of laying platform, crane span structure support, cable;
Overhead transmission line is connected to side terminal unit, and cable is converted into using font cable termination is foretold, and cable is from a lateral terminal list
Member is foretold font cable termination and is risen, and is arranged downwards towards crane span structure cell side tower body along terminal unit, into crane span structure unit, along crane span structure list
Cable bearer in member enters the terminal unit of the other side.
Further, the fore-telling font cable termination is made of end, arrester and insulator string.
Compared with prior art, beneficial effects of the present invention:Suitable for numerous across Xia Chuan highways, brill more overhead railway etc.
Occasion, compared with traditional cable version, construction cost caused by avoiding cable burial too deep increases with building time, transmits electricity simultaneously
Circuit is integrally located at ground or more, is convenient for operation and maintenance.
【Description of the drawings】
Fig. 1 is the structural schematic diagram of invention.
【Specific implementation mode】
To make the technical means, the creative features, the aims and the efficiencies achieved by the present invention be easy to understand, with reference to
Specific implementation mode, the present invention is further explained.
As shown in Figure 1, a kind of cable termination is with across crane span structure integral type tower, it is by two terminal units and a crane span structure list
Member composition, terminal unit member are located at crane span structure unit both sides, and the terminal unit includes tower body 1, ground wire cross-arm 2, topping wire cross
Load 3, lower layer conductor cross-arm 5, auxiliary cross-arm 6, foretells font cable termination 7, cable 10 at middle layer conductor cross-arm 4.
The ground wire cross-arm 2, topping wire cross-arm 3, middle layer conductor cross-arm 4, lower layer conductor cross-arm 5, auxiliary cross-arm 6 are located at
It is arranged from top to bottom on tower body, both sides cross-arm is arranged in every layer of cross-arm horizontal path direction.
The ground wire cross 2 carries on a shoulder pole taper and fixes ground wire, topping wire cross-arm 3, middle layer conductor cross-arm 4, lower 5 tip of layer conductor cross-arm
Conducting wire is fixed in portion, and taper, which is fixed, between topping wire cross-arm 3, middle layer conductor cross-arm 4, lower layer conductor cross-arm 5 and auxiliary cross-arm 6 foretells
Font cable termination 7.
The fore-telling font cable termination 7, is made of end, arrester and insulator string.
The crane span structure unit is made of laying platform 8, crane span structure support 9, cable 10.
The laying platform 8 is highly determined by lower section across facility between the terminal unit of both sides.The crane span structure support
9 need, according to apart from length, to bear the setting of the elements such as gravity.
A kind of cable termination as shown in the figure and leap crane span structure integrated tower schematic diagram:The present invention usually parallel built highway is built
If considering adjust the distance with road safety distance, conducting wire, is overall beautiful etc. factor, wear roadside under creates respectively
Terminal unit at one creates above Xia Chuan highways and crosses over unit at one, and overhead transmission line is connected to terminal unit, electric using font is foretold
Cable terminal is converted into cable 10, and cable 10 is from side terminal unit foretells font cable termination 7, along terminal unit towards crane span structure list
First side tower body one arranges that downwards, into crane span structure unit, the cable bearer in crane span structure unit enters the terminal unit of the other side.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, any made by repair
Change, equivalent replacement, improvement etc., should be included within the scope of the present invention.
