Study on the Vibration Mechanism and Response of Isolated Phase Enclosed Bus

针对离相封闭母线振动易引起的安全隐患,本文拟开展其振动机理与响应仿真分析。以水平布置的全连式离相封闭母线为例,建立动力学模型,分析短路故障时和地震作用下的母线振动响应机理,并进行仿真和对比分析。分析结果验证了母线确实存在振动,且振动强度带来的危害不容忽视。该研究为母线振动分析与减振研究提供理论依据。

In view of the potential safety hazards easily caused by the vibration of isolated phase enclosed bus, the vibration mechanism and response simulation analysis will be carried out in the paper. Taking the fully connected isolated phase enclosed bus with horizontal arrangement as an example, the dynamic model is established. The mechanisms of bus vibration response under short-circuit fault and earthquake are analyzed, and simulation and comparative analysis are carried out. The results of the analyses verify that the bus vibration does exist, and the harm caused by vibration intensity can not be ignored. This study provides a theoretical basis of bus vibration analysis and vibration reduction.
