摘要:
爲彌補目前仿真計算和變壓器整機試驗對特高壓變壓器飽和勵磁特性研究的不足,選取進口和國産的高磁感取向硅鋼片分別進行標准試樣的基礎磁性能測試,並分別搭建與特高壓變壓器結構相同、磁通密度等效的變壓器鐵心模型,基于該模型建立變壓器飽和勵磁特性檢測系統,對測試得到的標准試樣的基礎磁性能和變壓器模型的過勵磁特性進行了研究和分析。結果表明:特高壓變壓器硅鋼鐵心模型在過勵磁條件下,變壓器模型的勵磁特性與標准試樣的基礎磁特性變化的關系不完全符合計算公式;電壓波形能保持基本的正弦波形態,空載電流畸變嚴重,各高次諧波的比重相比增大;采用的同規格的進口和國産高磁感取向硅鋼片的標准試樣的基礎磁性能基本一致,對應的變壓器鐵心模型的飽和勵磁特性存在一定差異。
Abstract:
In order to make up for the lack of saturated excitation characteristics research with simulation calculation and transformer machine test on the UHV transformer, the basic magnetic test of imported and domestic high magnetic oriented silicon steel sheet standard samples were carried out. And transformer core models were built with the same structure, equivalent magnetic flux density as UHV transformer. Based on the models, the saturated excitation characteristic detection system of transformer was established. The basic magnetic characteristics of the standard samples and the over-excitation characteristics of the transformer model were studied and analyzed. The results show that, under over-excitation conditions, the relationship between the excitation characteristics of the transformer model and the base magnetic characteristics of the standard samples is not fully consistent with the calculation formula, distortion of no-load current is serious and the proportion of the higher harmonics increase, the basic magnetic characteristics of the standard samples of imported and domestic high magnetic oriented silicon steel sheets are basically the same and the saturated excitation characteristics of the corresponding transformer core model are different.
