油浸式三相变压器短路状态下电磁场数值模拟
Numerical Simulation on Electromagnetic Field of Oil-immersed Three-phase Transformer in Short-circuit Condition
摘要
Abstract
In order to correctly determine oil flow motion in the transformer oil tank,this paper uses ANSYS Maxwell software to conduct numerical simulation on 3D transient electromagnetic field of the oil-immersed three-phase transformer in short-circuit condition and obtains distribution of the electromagnetic field,electromagnetic force on winding and electromagnetic loss.Results indicate that at the time of U phase short-circuit,joint force on regulating winding is positive and with increase of time,the force decreases.In addition,ohmic loss value of the high tension coil is the largest while with changing of time,ohmic loss value gradually decreases.关键词
