Embodiment Construction

[0077] The catenary method is used to simulate the icing mechanical performance of optical fiber composite overhead ground wire OPGW optical cable. The catenary method is based on the condition that the unit load of the overhead line is uniformly distributed along its length to study and establish its calculation principles and calculation methods. The model of static suspended fiber optic cable is attached figure 1 As shown, two points A and B are used as suspension points. The catenary equation in the figure is:

[0078] y = a ( ch x a - 1 )

[0079] In the formula, a is the introduction parameter, which is the ratio of the horizontal tension H of the optical cable to the unit weight W. ch(x) is a hyperbolic cosine function.

[0080] In the natural suspension state of the optical cable, let t=1 / a, the catenary line equation is related...

Abstract

The invention provides a method for simulating mechanical properties of OPGW (optical fiber composite overhead ground wire) optical cable ice coating, comprising the steps of figuring out the maximum tension, the extension, the sag and the stress strain borne by the OPGW optical cable during ice coating, calculating and analyzing the influences of wind and temperature on the mechanical propertiesof OPGW ice coating.

Description

technical field [0001] The invention relates to the field of icing of special optical cables for electric power communication, in particular to a method for simulating the icing mechanical properties of an optical fiber composite overhead ground wire (OPGW). It is used to calculate the changes in parameters such as tension, elongation and sag of the optical cable under the conditions of icing, temperature, wind and other comprehensive meteorological conditions of the optical fiber composite overhead ground wire OPGW optical cable, so as to obtain the influence of icing on the transmission performance of the optical cable. Background technique [0002] In the past, there were few studies on the icing of optical fiber composite overhead ground wire OPGW optical cable, and most of them were based on the experience and achievements of transmission line icing, and there was a lack of targeted detailed analysis of the icing performance of optical fiber composite overhead ground wir...
