Abstract
The utility model discloses a composite outdoor cable terminal through connection station which comprises a steel-pipe pole body. A plurality of cable supports and connecting bars are distributed on the steel-pipe pole body. A strain insulator string, a seat-type arrester and a seat-type oil-filled cable terminal are mounted on each connecting bar. An overhead line is connected with a power cable through the strain insulator string, the seat-type arrester and the seat-type oil-filled cable terminal sequentially by the aid of overhead downleads. The power cable is led down to enter an underground cable channel step by step. By the composite outdoor cable terminal through connection station, space of the steel-pipe pole body is fully utilized, and the connection station occupying small space can satisfy use requirements. The overhead downleads are stable and reliable in connection, the problems that electric clearance between the overhead downleads is insufficient due to excessive swinging under wind blowing and fatigue damage of partial connecting structures due to the excessive swinging can be avoided, and accordingly overall connecting safety and reliability are guaranteed.
Description
Technical field
The utility model relates to ultra-high-tension power transmission line, is specially a kind of combined type outdoor cable terminal group through-connection station.
Background technology
Along with Chinese Urbanization's speeds up; Site coverage strengthens in the city proper; Reduce in available space, and for conservation of power corridor and beautifying urban environment, part need change cable line into to a lot of overhead transmission lines in the city; Wherein the cable termination group through-connection station need be adopted in overhead transmission line and cable line junction, and overhead transmission line is transferred in the underground cable ditch.Present used cable termination group through-connection station exists all generally that floor space is big, built on stilts draws the lower wire instability and be easy to occur the unexpected problem of electrical safety.
Summary of the invention
To the problems referred to above, the utility model provides a kind of floor space little, the built on stilts reliable and stable combined type outdoor cable terminal group through-connection station of lower wire connection that draws.
The utility model is that the technical scheme that its technical problem of solution is adopted is:
Combined type outdoor cable terminal group through-connection station; Comprise the steel pipe pole main body; Be distributed with several cable beareves and connecting rod on the steel pipe pole main body on the position of differing heights; Strain insulator string, seat formula lightning arrester and seat formula Oil-filled Cable End are installed on the connecting rod; The built on stilts lower wire that draws of overhead transmission line utilization is connected with power cable through strain insulator string, seat formula lightning arrester, a seat formula Oil-filled Cable End successively, and power cable draws downwards step by step through some cable beareves and connects and get at last the underground cable ditch.
As preferred embodiment, seat formula Oil-filled Cable End is arranged along stagger arrangement before and after the overhead transmission line direction on connecting rod with seat formula lightning arrester.
As preferred embodiment, said cable bearer and connecting rod are arranged on the steel pipe pole main body with the mode at interval parallel to each other.
As preferred embodiment, the steel pipe pole main body is provided with cat ladder.
The beneficial effect of the utility model is: the set-up mode of the utility model cable bearer and connecting rod can farthest utilize the space of steel pipe pole main body, guarantees that group through-connection station is taking up an area of the requirement that also can satisfy use under the minimum situation; The utility model built on stilts draws lower wire to be adopted cable bearer to draw step by step downwards to connect; Its connection is reliable and stable; Can not make that the electric clearance that draws between the lower wire is not enough even receive wind blows because of excessively swinging yet; Can not cause partially connected architecture because of excessively swing fatigue damage yet, guarantee whole attachment security reliability.
Description of drawings
Further explain below in conjunction with accompanying drawing and embodiment:
Fig. 1 is the overall structure sketch map of a kind of embodiment of the utility model;
Fig. 2 be among Fig. 1 A to the drawing of position.
Embodiment
See figures.1.and.2; Combined type outdoor cable terminal group through-connection station; Comprise steel pipe pole main body 1; Be distributed with several cable beareves 2 and connecting rod 3 on the steel pipe pole main body 1 on the position of differing heights; Strain insulator string 4, seat formula lightning arrester 5 and seat formula Oil-filled Cable End 6 are installed on the connecting rod 3, and the built on stilts lower wire that draws of overhead transmission line utilization is connected with power cable through strain insulator string 4, seat formula lightning arrester 5, a seat formula Oil-filled Cable End 6 successively, and power cable draws downwards step by step through some cable beareves 2 and connects and get at last the underground cable ditch.Steel pipe pole main body 1 generally is fixed on the ground through anchor bolt, and the stressed size of main body 1 is generally considered according to the lead in 300 square millimeters of cross sections.As shown in Figure 1; Cable bearer 2 is arranged on the steel pipe pole main body 1 with the mode of connecting rod 3 with interval parallel to each other; The built on stilts lower wire that draws is connected to the seat formula lightning arrester 5 that is connected to the below behind the strain insulator string 4 earlier; Jumped by seat formula lightning arrester 5 and pass to a formula Oil-filled Cable End 6, power cable draws downwards step by step along cable bearer 2 and receives in the underground cable ditch then.
As preferred embodiment, as shown in Figure 2, seat formula Oil-filled Cable End 6 is arranged along stagger arrangement before and after the overhead transmission line direction on connecting rod with seat formula lightning arrester 5; Power cable with built on stilts is connected stable, reliably; Easy construction, safe, and the annex that adopts is few, and whole smooth, attractive in appearance.
In order to make the safety system coefficient of the utility model further increase, the preferably built on stilts lower wire that draws has pillar 7 near the outer setting of the part of steel pipe pole main body 1 bottom position.In addition, the maintenance personal carries out maintenance and repair to group through-connection station for ease, and steel pipe pole main body 1 is provided with cat ladder.
The execution mode of the utility model is not restricted to the described embodiments, as long as it reaches the technique effect of the utility model with essentially identical means, all should belong to the protection range of the utility model.
