摘要

中国科学院等离子体物理研究所(ASIPP)正在建设超导导体试验装置,以评估工程技术的可靠性和聚变反应堆运行环境下的安全运行。由于该试验装置的铌3硒层线圈采用了风amp的制造工艺,作为匝间绝缘材料的高强度玻璃纤维在经过665℃高温热处理后会发生碳化,从而降低绕组的机械性能和电气性能。为改善玻璃纤维热处理后的性能,开发了高强度玻璃纤维表面脱碳改性工艺。通过线圈绕组径向压力测试和 VPI 样品性能测试,验证了所开发的玻璃纤维带处理工艺能够满足层状 Nb3Sn 超导磁体的制造工艺要求。该处理技术已成功应用于实验磁体的制造,为大型 Nb3Sn 层线圈的绝缘制造提供了技术支持。

Research on Insulation Technology for Nb3Sn Layer Coil of Superconducting Conductor Testing Facility

The Superconducting Conductor Testing Facility, which is developed to evaluate the reliability of engineering technology and safe operation in a fusion reactor operation environment, is under construction by the Institute of Plasma Physics, Chinese Academy of Sciences (ASIPP). Since the Nb3Sn layer coil of this test facility adopts the manufacturing process of the wind & react, the high-strength glass fiber used as the inter-turn insulation material will carbonize after high-temperature heat treatment at 665℃, thereby reducing the mechanical and electrical properties of the winding. The surface decarburization and modification process of high-strength glass fiber was developed to improve the properties of glass fiber after heat treatment. It is verified that the developed glass fiber tape treatment process can meet manufacturing process requirements of layered Nb3Sn superconducting magnets through the coil winding radial pressure test and VPI sample performance test. This processing technology has been successfully applied in the manufacturing of experimental magnets, providing technical support for the insulation manufacturing of a large Nb3Sn layer coil.

期刊介绍: The Journal of Fusion Energy features original research contributions and review papers examining and the development and enhancing the knowledge base of thermonuclear fusion as a potential power source. It is designed to serve as a journal of record for the publication of original research results in fundamental and applied physics, applied science and technological development. The journal publishes qualified papers based on peer reviews. This journal also provides a forum for discussing broader policies and strategies that have played, and will continue to play, a crucial role in fusion programs. In keeping with this theme, readers will find articles covering an array of important matters concerning strategy and program direction.
