300kVA高温超导变压器电流引线漏热损耗的测量

An experiment on measuring the heat loss of the current lead of 300kVA HTS transformer

电流引线是高温超导变压器的主要外部漏热来源,它的漏热量直接影响了超导变压器的经济性能,因此,引线的设计与漏热测量一直备受关注。文中构建了一个实验方案,运用量热法测量低压引线的漏热,并将试验结果与仿真预期值进行了对比和分析,从而验证了仿真设计的正确性。

The current lead of HTS transformer is a part that leads to leak out heat, its design and fabrication influence greatly the loss of nitrogen during operation. It is importance to calculate and identify the heat leak of the current lead. Based on heat transfer theory, this paper designed an experiment to measure the heat loss of the current lead of 300kVA transformer and analyzed the data of the experiment. The experimental results show a good according with the simulation.
