摘要:
干式空心电抗器振动强、噪声大一直是突出问题,研究电抗器的振动特性对于其减振降噪 具有重要意义。从电抗器振动产生过程出发,建立了电抗器电磁-机械三维有限元仿真模型。基于 场-路耦合原理,分析了电抗器磁感应强度分布、电磁力变化特点;基于动力学理论,进行模态分析 和谐响应分析,研究了电抗器在不同状态下固有频率和模态振型的变化规律,以及加速度响应和振 动特性。结果表明,电抗器振动以100 Hz 频率为主,内侧包封振动大于外侧包封,不同约束状态 下,电抗器的振动特性有所差异。研究结果为电抗器减振降噪、绝缘保护以及结构稳定性提供了有 效依据和支持。
Abstract:
The strong vibration and big noise of dry?type air?core reactor are always a prominent problem. It is of great significance to study the vibration characteristic of dry?type air?core reactor for its vibration and noise reduction. Starting from the generation process of reactor,a three?dimensional finite element simula? tion model of electromagnetic?mechanical reactor is established. The characteristic of magnetic induction intensity distribution and electromagnetic force variation of reactor is analyzed based on the field?circuit coupling principle. On the basis of dynamic theory,modal analysis and harmonic response analysis are car? ried out to study the variation law of inherent frequency and modal vibration shapes,acceleration response as well as vibration characteristics of reactor under different states. It is shown by the result that the main frequency of reactor vibration is 100 Hz,and the vibration of inner envelope is greater than that of outer envelope. Under different constraints,the vibration characteristic of reactor is different. The study results provideaneffectivebasisandsupportforthevibrationandnoisereduction,insulationprotectionandstructural stability of the reactor.
