摘　　要：电力变压器的短路电抗是运行过程中表征变压器本体抗短路电流冲击能力的重要参数。根据变压器的短路电抗可判断变压器绕组是否发生变形,研制了一套变压器绕组变形的在线监测系统。经实际测试与分析,该系统能够在线监测变压器短路电抗,可对变压器绕组变形进行长时间监测。The short-circuit reactance is an important parameter to characterize the transformer ability to resist the attack of short-circuit current in the design in the operation process.This paper expounds whether the transformer winding deformation exists can be judged by the measuring of the transformer short-circuit reactance.Therefore,a set of on-line monitoring system of transformer winding deformation is developed.Through the actual test and analysis,it is proved that the system can monitor the transformer short-circuit reactance and facilitate the long time monitoring of transformer winding deformation.
