Abstract

A 1 250 kV·A/10.5 kV/0.4 kV three-phase high temperature superconducting (HTS) transformer has been designed, integrated,tested and grid-connection demonstrated.The windings of the HTS transformer are made from copper alloy enforced Bi2223/Ag tapes,and the structures of the primary and secondary windings are solenoid and double-pancake,respectively.The three-phase three-limb core is composed of oriented silicon sheet steel,and the cryostat is made of low-temperature resistant glass fiber enforced plastics with room temperature bore.According to the tests,the no-load loss is 2 319.2 W,the no-load current is 0.254%,the short-circuit impedance is 5.6%,and the average load loss is 249 W.Besides,the maximum leakage current between primary and secondary windings is about 12.6 mA under the power frequency voltage withstand test of 35 kV/1 min/50 Hz,and the negative full wave lighting impulse test with a peak voltage of 75kV/1.2 μs/50 μs from the primary winding is carried out.The grid-connection demonstration of the HTS transformer was carried out since September 9th,2014 and is reliable until now.
