| 中文摘要: |
| 干式空心电抗器在变电站运行中发挥着重要作用。为了有效控制电抗器噪声的环境影响，该文利用特征系统实现方法，针对通电作用下的电抗器模态特性进行了试验分析。结果表明，干式空心电抗器的前5阶固有频率出现在其通电运行状态的作用频率中，并可能成为其在通电运行条件下发生噪声增强和设备损坏的重要原因，该研究将为改进其设备共振问题提供重要依据。 |
| 英文摘要: |
| It is an important part of the power system operation for the dry-type air-core reactor. This paper investigates the experimental modal characteristics in the work condition based on the eigensystem realization algorithm method. The result shows that the lower order resonance frequency of the dry-type air-core reactor existed in the work excitation frequency, which was one of the most important reasons of the equipment damage and noise enhancement during the work condition. The result provides the imperative data for improving the resonance of the equipment. |
