The utility model technical issues that need to address provide the conversion jockey of the bundle conductor on a kind of ultra-high-tension power transmission line.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is:
A kind of ultra-high-tension power transmission line bundle conductor conversion jockey, comprise two aluminum pipes that be arranged in parallel and the suspension conductor spacer between two aluminum pipes, the two ends of every aluminum pipe are provided with contiguous block, contiguous block is provided with the arc wire clamp of half U type arc structure, and an end of arc wire clamp is binding post, the connecting plate of the other end for being connected with contiguous block.
Further improvement of the utility model is: the connecting plate of described arc wire clamp is the slab construction that is provided with connecting hole, and the side of contiguous block is provided with corresponding with it connecting hole, and the connecting plate of arc wire clamp carries out the transition to binding post through the half U type arc structure.
Further improvement of the utility model is: the same end of every aluminum pipe is provided with two arc wire clamps and forms quadrifid power transmission line form, and every aluminum pipe of the other end is provided with three arc wire clamps and forms sexfid power transmission line form.The cross section of contiguous block and arc wire clamp link is a quadrangle, limit parallel with two aluminum pipe parallel surfaces on the contiguous block of the same end of aluminum pipe connects the arc wire clamp respectively, the limit parallel with two aluminum pipe parallel surfaces and the limit of two aluminum pipe outside vertical also are connected the arc wire clamp respectively on the contiguous block of the aluminum pipe other end, realize four, the conversion of six-multiple conductor connects.
Because the technological progress of having adopted technique scheme, the utility model to obtain is:
Arc wire clamp one end of the present utility model is binding post, the connecting plate of the other end for being connected with contiguous block, connecting plate is the slab construction that is provided with connecting hole, the corresponding with it connecting hole of setting is arranged on the side of contiguous block, connecting plate is connected with contiguous block by bolt, and the connecting plate of arc wire clamp carries out the transition to binding post through the half U type arc structure.Be connected with common wire clamp and compare, the dismounting of bolt ease of connection can be according to the number of the split form flexible transformation arc wire clamp of lead, and the half U type arc structure of arc wire clamp, helps satisfying the corona requirement.
The same end of every aluminum pipe of the utility model is provided with two arc wire clamps, and three arc wire clamps are set on the every aluminum pipe of the other end, and the conversion that can finish four, six lead split forms on the ultra-high-tension power transmission line connects.Be arranged on the cross sectional shape of aluminum pipe two ends contiguous block and the arc wire clamp number that is attached thereto by change, the conversion that can also realize other split form lead on the ultra-high-tension power transmission line connects, as the aluminum pipe two ends two arc wire clamps are set all, realize that the conversion of conductors on quad bundled connects; The aluminum pipe two ends all are provided with three arc wire clamps, realize that the conversion of six-multiple conductor connects.
In addition, the cross sectional shape that can also be by changing contiguous block and the number of arc wire clamp are to satisfy the variation requirement of various lead split forms.Connection as needs eight bundle conductors, the cross sectional shape that contiguous block can be set is a pentagon, also the number of the arc wire clamp of bolt is four with it, therefore the utility model not only can be applied in the 500kV ultra-high-tension power transmission line, can also be applied in the electric power system of voltage levels more.
