Embodiment
[0058]Embodiment: The method for simulating and calculating the tension change of a single-gear conductor of a transmission line in this embodiment is used to simulate the change of the horizontal tension of the conductor caused by the change of the span of the transmission line. The steps of the simulation calculation method are as follows:
[0059] (1) According to the span and height difference of the actual design conditions of the transmission line, determine the type of conductor and the comprehensive load g;
[0060] (2) According to the wire type, obtain the cross-sectional area A of the wire, the modulus of elasticity of the wire E and the initial tension T m ;
[0061] (3) According to the above parameters, obtain the final horizontal deflection △L of the clamp at the bottom of the hanging string, divide △L into n parts of the horizontal displacement △l on average, △L=n×△l;
[0062] (4) Establish the relationship between the horizontal displacement of the bottom cla...
