【摘要】 电力变压器在运行过程中会受到短路电流的冲击,从而导致绕组发生轴向或者径向位移。短路电抗是反应变压器绕组状态的有效参数之一,利用C8051F040和WinCE 6.0平台设计了短路电抗的在线监测系统,并在一台模型变压器上验证了系统的稳定性。更多还原

【Abstract】 Windings of power transformer may suffer from the impact of short-circuit current,which can lead to different wind ing displacements such as axial displacement and radial displacement.The short-circuit reactance is one of the effective parame ters to reflect the status of transformer windings.An on-line monitoring system of transformer short-circuit reactance was designed by means of C8051F040 and WinCE 6.0 platforms.The stability of the monitoring system was verified by a transformer model.更多还原
