Embodiment 1

[0070] Such as Figure 1-2 As shown, the invention of this example provides a method for determining the breeze vibration of split conductors considering the damping parameters of spacers, comprising the following steps:

[0071] 1. Determination of the damping parameters of the spacer clamp

[0072] The damping parameters of spacer clamps can be determined through tests, and the test methods are as follows.

[0073] The body of the spacer bar to be tested is fixed rigidly on the test bracket, and a certain weight is applied to the clamp of the spacer bar. Apply a tangential force along the direction of the rotation circle of the spacer clamp, so that the clamp rotates to the limit position, stays for one minute, and then releases suddenly, allowing the clamp to vibrate freely. Install an acceleration sensor on the clamp, and record the displacement curve of the free attenuation vibration of the clamp through the data acquisition system, for example figure 1 shown.

Abstract

The invention relates to a bundled conductor aeolian vibration determination method considering a spacer damping parameter. The method is based on spacer line clamp damping parameter computational analysis and experimental study and combines a spacer average subspan calculation method, the real spacer damping is applied to a proper position of a bundled conductor, and finally, solution of bundled conductor aeolian vibration is realized with a finite element method, so that the bundled conductor aeolian vibration level is determined, and a reference is provided for anti-vibration design of lines. The method can make up defects of solving bundled conductor aeolian vibration on the basis of a traditional reduction factor method.
