本文介绍了超导电力装置用低温液体的高压绝缘技术。超导变压器的绝缘分为几个绝缘成分。此外，我们还研究了超导和低温环境特有的基本绝缘特性：面积和体积对击穿强度的影响、V-t特性、失超动态击穿特性等。最后，对低温液体的电绝缘进行了系统化，并为超导电力设备的实际绝缘设计提供了流程图。
This paper describes high voltage insulation technology of cryogenic liquids for superconducting power apparatus. The insulation of a superconducting transformer is classified into several insulation components. Moreover, we investigate fundamental insulation characteristics peculiar to the superconducting and cryogenic circumstances: area and volume effects on breakdown strength, V-t characteristics, quench induced dynamic breakdown characteristics and so on. Finally, we systematize the electrical insulation of cryogenic liquids, and propose a flow chart for the practical insulation design of superconducting power apparatus.
