摘要: 利用计算机仿真软件,模拟风力发电机舱内的实际环境,建立了变压器电磁和热仿真模型,并进行了合理的仿真计算,为变压器电磁设计及散热设计提供计算依据,并与最终变压器实测平均温升进行对比,验证仿真计算准确性。除了变压器本体温升,本论文还考虑了机舱顶部风扇和变压器下部风扇以及机舱内其他发热部件对于变压器的温升影响。本结论对于密闭外壳内干式变压器温升设计及散热风扇的选取有指导作用。
Abstract: The computer simulation software is used to simulate the actual environment in the wind turbine cabin, the electromagnetic and thermal simulation model of the transformer is established, and the reasonable simulation calculation is carried out to provide the calculation basis for the electromagnetic design and heat dissipation design of the transformer, and the accuracy of the simulation calculation is verified by comparing with the actual measured average temperature rise of the final transformer. In addition to the temperature rise of the transformer itself, the influence of the engine room top fan and the lower fan of the transformer as well as other heating parts in the engine room on the temperature rise of the transformer is also considered in this paper. This conclusion can be used as a guide for temperature rise design of dry type transformer and selection of cooling fan.
