摘要

均压环作为高压输电设备中均化电场的关键部件，常因风载荷作用引发振动，导致结构疲劳甚至断裂。本文提出一种通过增加配重优化均压环动力特性的风振抑制方法。首先建立均压环-配重系统的动力学模型，分析配重对固有频率和振型的调控机制；其次通过有限元仿真验证提高配重方案对风振频率的抑制效果；最后结合新疆哈密某换流站电容器组配套均压环风振案例，验证配重优化方案的工程适用性。。

Abstract

The grading rings，as a key part for electric field homogenization in high-voltage transmission equipment，often experience vibrations induced by wind loads，leading to structural fatigue or even fracture. In this paper a wind-induced vibration suppression method by optimizing the dynamic characteristics of grading rings through counterweight addition is proposed. First，a dynamic model of the grading ringcounterweight system is set up to analyze the regulatory mechanism of counterweights on natural frequencies and vibration modes. Then，finite element simulation is used to verify the vibration suppression effect of the counterweight-enhanced scheme on wind-induced frequencies. Finally，the engineering applicability of the counterweight optimization scheme is verified through a case study of wind-induced vibrations in grading rings installed on capacitor banks at a converter station in Hami，Xinjiang.
