摘　　要：通过开展带局部放电检测的感应耐压试验,对运行年限过高且经过移位后的大型变压器的内部绝缘情况进行绝缘检测与验证,在投运前评估其运行的可靠性,以确保设备安全运行及系统的安全性。By conducting inducted overvoltage withstand tests with partial discharge detection,the internal insulation of large transformers that have been operated for too many years and have been relocated are tested and verified,and their operational reliability is evaluated before they are put into operation,so as to ensure the safe operation of the equipment and the safety of the system.

关 键 词：变压器 局部放电试验 感应耐压试验 绝缘检测
