摘要
A 50 kA superconducting transformer has been manufactured and tested. In order to be assembled easily, two terminal boxes were fabricated and connected to the legs of the secondary coil. The performances of the transformer were tested. This paper is focused on the test of the joints resistance and the heat transfer calculation of losses in the supercritical helium channel of the terminal boxes. The temperature of the copper block of a terminal box was calculated and compared with the temperature measured in the test in the current range of 0–55.8 kA. The test results indicated that the design satisfied the requirements.
