IEE在河南巩义中富实业有限公司的自备发电厂安装了一条360米长的高温超导(HTS)直流电力电缆。该电缆将19.5MVA/1.5KA可控硅整流器与110千伏/1千伏变压器连接到电解铝电解槽的母线上。设计载流10kA，电压1300V。高温超导直流电力电缆芯由5层导线缠绕而成，由40公里长的Bi2223导线拼接而成。电缆芯有五层，每层有23根高温超导导线，外径45 mm。作为本项目的项目，进行了4~5m长的原型电缆的试验，包括在360m电力电缆之前制造的5m原型电缆和从360m高温超导电力电缆截取的4m原型电缆。这些样机用于评估360m/10kA高温超导电力电缆的设计方案、制造工艺和性能，包括在10kA设计电流下的稳态运行和过电流故障能力。在77K、1μV/cm时，5m和4m高温超导电力电缆的临界电流分别达到14.3kA和13.8kA。本文介绍了IEE公司研制的360m/10kA高温超导直流电力电缆的设计参数和制作方法。介绍了4m和5m原型光缆的光缆系统、安装过程和试验结果总结。此外，还给出了初始冷却过程和通电过程的详细信息。
IEE has installed a 360-m-long high-temperature superconducting (HTS) dc power cable at the self-supply power plant of Zhongfu Industrial Co., Ltd. in Gongyi, Henan. The cable connects a 19.5 MVA/1.5 kA silicon-controlled rectifier, which connects with a 110 kV/1 kV transformer, to the bus bar of an electrolytic aluminum cell. It is designed to carry 10 kA current and the voltage is 1300 V. The HTS dc power cable core consists of five conductor layers wound with the spliced Bi-2223 wires with the length of 40 km. The cable core has five layers and 23 HTS wires in each layer with the outer diameter of 45 mm. As the items in this project, testing of 4 to 5 m length prototype cables, including a 5 m prototype cable fabricated before the 360 m power cable and a 4 m prototype cable intercepted from the 360 m HTS power cable, is conducted. These prototypes are used to assess the design program, fabrication process, and performance of the 360 m/10 kA HTS power cable including steady state operation at the 10 kA design current and overcurrent fault capability. The critical current of the 5 and 4 m HTS power cable reach 14.3 kA and 13.8 kA at 77 K, 1 μV/cm, respectively. In this paper, the design parameters and fabrication of the 360 m/10 kA HTS dc power cable conducted by IEE are presented. The cable system, installation process and the summary of the results from the testing of 4 and 5 m prototype cables are described. In addition, details of the initial cool-down process and energizing are presented.
