Abstract:
As the length of transmission lines increases year by year, it is more and more difficult to drill 110 kV single-circuit lines over 220 kV lines. Aiming at the problem of scheme selection for 110 kV single-circuit line drilling over 220 kV line, the restrictive factors of the drilling over scheme were analyzed, and measures such as changing the wire arrangement, 0 deg inner angle winding and 90 deg outer angle winding were adopted to carry out the drilling over Design and optimization of the tower, a single-circuit full-angle drilling tower is designed, which provides a feasible solution for 110kV single-circuit line drilling over 220kV line.
