摘　　要：基于750 kV联络变压器对短时感应耐压试验(ACSD)方法进行了研究,针对目前变压器电压等级及容量的增加,电压支撑法的运用有效解决了兼顾考核高电压等级变压器各线端纵绝缘和相间绝缘强度的要求。经过对750 kV联络变压器中线点电压支撑试验线路各线端电压进行准确计算,通过出厂试验验证了该试验方案的可行性。Based on 750 kV Interconnecting Transformer,the essay studied the Short-duration induced AC withstand Test for 750 kV Interconnecting Transformer. For the capacity and voltage levels of transformer increased. Voltage support method effectively solved the assessment of each ends vertical insulation and phase insulation of high voltage level transformer. Based 750 kV transformer voltage support each neutral point voltage test circuit,calculated each line voltage,and the test results verified the way viable.
