Background technology
Draw in lower engineering in existing overhead transmission line cable, when cable draws lower point is close to built anchor support, if passing through Under newly-built anchor support realizes that cable draws, newly-built anchor support forms little isolated shelves with built anchor support, causes built anchor support side Tension force reduces, both sides unbalanced tensile force increase, it is difficult to meet use condition, need to remove reconstruction;If being realized by newly-built tangent tower Under cable draws, then newly-built steel tower utilization rate is not high, and serious waste of resources, land seizure are larger, and overall aesthetics is poor, therefore, Propose to draw lower scheme using existing iron towers of overhead power transmission lines cable, reduce quantities, it is to avoid the wasting of resources.
It is therefore proposed that a kind of existing power line tension steel tower cable draws under type, wire is hung using built anchor support, Newly-built base single loop cable draws lower beam and realizes target.
The content of the invention
In order to overcome the deficiencies in the prior art, the present invention to provide existing single loop strain insulator steel tower cable and draw lower beam, it is adapted to tight Patch anchor support construction, draws the cable termination on lower beam by drawing wire at lower point and being connected to existing single loop strain insulator steel tower cable Place, realizes that single loop T connects, cut-offs and reconfiguration, does not change and draws downside anchor support stress, it is to avoid the dismounting of old tower is rebuild, with new Build straight line, anchor support to compare, construction cost is greatly reduced, reduce floor space.
The present invention solves the technical scheme that adopted of above-mentioned technical problem:
Existing single loop strain insulator steel tower cable draws lower beam, including shaft, upper strata cross-arm and lower floor's cross-arm, and the upper strata cross-arm is placed in The top of shaft, arranges both sides cross-arm towards existing anchor support tower body, in V-shape;Lower floor's cross-arm is placed in upper strata cross-arm Both sides cross-arm is arranged towards existing anchor support tower body in lower section, lower floor's cross-arm, in V-shape;Double I types are installed on the upper strata cross-arm Cable termination, is provided with fore-telling font cable termination between upper strata cross-arm and lower floor's cross-arm.
Described pair of I types cable termination is made up of A seating end, A seating arrester and copper bar, and A seating end is placed in shaft Top, A seating arrester is placed at the cross-arm of upper strata, and A seating end is connected using copper bar with A seating arrester.
The fore-telling font cable termination is made up of end, suspension insulator and arrester, end, suspension insulator String and arrester cooperation are assemblied between upper strata cross-arm and lower floor's cross-arm ending.Suspension insulator is fixed on upper strata cross-arm slightly Portion, arrester are fixed on lower floor's cross-arm ending, and end one end is fixed between suspension insulator and arrester, and one end is fixed In the middle part of lower floor's cross-arm.
Beneficial effects of the present invention:1)Existing single loop strain insulator steel tower cable draws lower beam, is adapted to be close to anchor support construction, only By drawing under at lower point, terminating wire draws;2)Realize that single loop T connects, cut-offs and the several functions such as reconfiguration;3)Do not change under drawing Side anchor support stress, it is to avoid the dismounting of old tower is rebuild;4)Compared with newly-built straight line, anchor support, construction cost is greatly reduced, is subtracted Small footprint size.
