[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings of the specification, as shown in the figure:
[0024] The invention provides an ice disaster defense method with a distributed hanging weight restraining wire twisting, including the following steps:
[0025] S1. Collect transmission line parameters, which include the equivalent icing thickness of the transmission line and the line span length;
[0026] S2. Calculate the eccentric moment of the eccentric ice forming the airfoil on the transmission line under the condition of no torsion of the transmission line;
[0027] S3. Determine the total moment of the pendant weight according to the weight and shape of the pendant weight, and the total moment is equal to the eccentric moment; where the eccentric moment and the total moment of the pendant weight are calculated and determined by existing methods;
[0028] S4. Determine the number and distribution spacing of the hangi...
