针对在平面叠铁心变压器信号模型中时栅激励信号的三相不平衡问题,提出了一种基于立体卷铁心自耦变压器的模型来确保三相时栅激励信号的对称性加载。理论分析、优化设计证明了方案的可行性,试验验证了该方案可有效解决时栅激励信号对称加载的问题。
Based on the problem that the time grating excitation signal is three-phase imbalance in plane fold core transformer signal model,a model based on three-dimensional wound core autotransformer was put forward to ensure the three-phase time grating excitation signal loaded symmetrically. Feasibility of the scheme is proved by detailed theoretical analysis and optimization design. And the problem of the time grating excitation signal loaded symmetrically is solved effectively by the scheme,which is verified by experiment.
