高场加速器和核聚变磁体需要卓越的电气绝缘以获得最佳性能。为了达到最大的场强和系统寿命，必须采用高强度和高模量的绝缘材料。一种新的可缠绕无机绝缘系统已经开发，结合了陶瓷复合材料的高强度和模量与有机绝缘的易于加工。这种新型陶瓷绝缘在超导体热处理之前应用，可以从600/spl°C到900/spl°C进行加工。这些特性使其成为风力和反应制造方法的理想选择，从而允许更复杂的线圈设计并降低加工成本。这里所描述的陶瓷绝缘的开发工作已经实现了目前高强度有机绝缘的两倍压缩模量。本文介绍了这种可包覆无机绝缘系统的热学、力学和电气性能。给出了剪切、压缩和介质击穿强度试验结果。
High field accelerator and fusion magnets demand superior electrical insulation for top performance. To achieve maximum field strength and system lifetime, high strength and high modulus insulation must be employed. A new wrappable inorganic insulation system has been developed that combines the high strength and modulus of a ceramic composite with the ease of processing of an organic insulation. This new ceramic insulation is applied prior to the superconductor heat treatment and can be processed from 600/spl deg/ to 900/spl deg/C. These properties make it ideal for wind and react manufacturing methods, thus allowing more complex coil designs and reduced processing costs. Development work on the ceramic insulation described here has achieved double the compression modulus of current high strength organic insulation. This paper describes the thermal, mechanical and electrical performance of this wrappable inorganic insulation system. Shear, compression, and dielectric breakdown strength tests results are presented.
