近年来，强风作用对高压电气设备的正常运行日益构成严重威胁。单臂隔离开关是易受强风影响的重要高压设备之一。文针对风载作用频段内的单臂隔离开关模态特性，利用随机子空间方法进行了试验研究。结果表明，单臂隔离开关的低阶共振频率出现在风载的作用频率中，并可能导致其在风载条件下发生破坏。对单臂隔离开关开展模态试验研究，将为改进其抗风能力提供重要依据。

The power failure during the storm is usually caused by damages of high voltage equipment. The semi-pantograph disconnector is one of the most important part for the power system operation, which is easily influenced by storm. Therefore, this paper investigates the experimental modal characteristics in the wind speed spectrum based on the Stochastic Subspace Identification method. The result shows that the lower order resonance frequency of the disconnector exists in the wind excitation frequency, which can lead to the equipment damage during the storm. The result provides the imperative data for improving the wind resistance of the equipment.
