Research On 3D Design Of Construction Scheme For Crossing Of High Voltage Overhead Transmission Lines

Although the overhead transmission line design has been computer-aided design,and began to try three-dimensional design,but the cross-over construction design is still using artificial experience design,rough design,security risks,long cycle,poor economy,the paper attempts to solve The problem.Paper designed a software platform,and through the interface to read the main data line design used in the construction design.Innovatively established a cross-over construction program of three-dimensional check method to check the maximum load,the maximum wind and outlet short-circuit under several extreme conditions such as wire galloping caused by electrical clearance,so that the construction program is safe and controllable,economical and reasonable,shortening the design and construction cycle,and the resulting information generated by this technology can play a role in supporting data throughout the entire life cycle of the grid.Design completed functional modules include: terrain design,cross design,equipment design and tower line design.Solve the three-dimensional space measurement accuracy,across the archway corridor within the ground elevation accuracy.The platform is applied to a cross-over construction design example of 220 kV and 35 kV overhead transmission lines,which verifies the validity and advancement of this platform.
