摘要: 通过获得绕组匝间短路故障的电磁场特征量,可以判断绕组匝间短路故障的位置和故障程度,对于及时发现绕组匝间短路故障具有重要意义.首先建立了变压器匝间短路电磁耦合模型,通过匝间短路故障下绕组电流的仿真值与试验值的对比验证了所建仿真模型的准确性和有效性.随后研究了高压绕组发生匝间故障时绕组电流、铁芯和绕组磁通的变化,并深入分析了匝间短路绕组匝数、短路位置对上述参量的影响.研究结论可为三相变压器不同部位及不同严重程度的绕组匝间短路故障的诊断提供理论依据.

Abstract: The locations and severity of interturn short circuits in windings can be determined from the characteristic electromagnetic field parameters associated with such faults, which is crucial for their timely detection. This study establishes an electromagnetic coupling model for interturn short circuits in transformer windings and verifies its accuracy and effectiveness by comparing simulated and experimental winding currents under interturn short circuit conditions. Subsequently, the variations in winding currents, core flux, and winding flux when interturn faults occur in high-voltage windings are investigated. The effects of the number of short-circuited turns and the fault location on these parameters are further analyzed in depth. The findings of this study provide a theoretical basis for diagnosing interturn short circuits at different locations and of different severity in three-phase transformers.
