Tensioning tower center displacement

The displacement of tensioning tower center of transmission lines refers to a certain distance moved by the center pile of the tower along the vertical direction of the road, which is the basis for constructing the tower. The basis of line construction measurement is the designed line strike diagram, but for the large corner of the tower center pile displacement, general strike diagram will not explain, this work must be determined by the engineering and technical personnel according to the line situation. The purpose of doing so is to improve the force on adjacent towers or reduce the inclination Angle and swing Angle of the dangling insulator string of adjacent straight towers, which is especially obvious in the corner tower greater than or equal to 60 degrees. If the center of the pole tower with a large Angle is not shifted, it is bound to cause the tilt of the dangling insulator string of the pole tower and the uneven force of the wire. When encountering bad weather, it is easy to cause the insufficient protection gap and even the major operation accident of the pole tower head broken. This problem should be paid great attention to by construction technicians in the construction of transmission lines.

When the wires change from the vertical arrangement of the double-circuit tensioning corner tower to the horizontal (or triangular) arrangement of the single-circuit tower, the horizontal deviation of insulator strings of the single-circuit tower adjacent to the double-circuit tensioning corner tower often increases greatly. In order to ensure the operation safety of the adjacent linear tower, when the displacement value of the double-circuit tensioning corner tower is determined, It is also necessary to consider whether the swing Angle of adjacent single-loop linear tower insulator strings exceeds the allowable value under the conditions of maximum wind speed, internal overvoltage and external overvoltage.
