摘 要: 这篇论文主要是完成NSTX托卡马克装置中欧姆加热线圈的电磁分析和工程设计。在计算OH线圈的电磁分布和电感时,应用毕奥-沙伐公式,通过椭圆积分简化计算,然后把求解过程转化成计算机语言,经反复调试和修改得到一个满足要求的结果。在OH线圈的工程设计中,962匝线圈采用双线并绕的绕制方式,四层线圈所形成的八个子绕组在电气上构成一条串联支路,并且有八条独立并行的冷却路径,文中还给出了线圈温度和冷却水流速的计算结果。在OH线圈中,同层线圈匝间的最大电压达到了1.5kV,由于OH线圈长度较长无法放置于真空压力容器中,因而在线圈的电气绝缘处理中采用一种新的真空压力浸渍工艺技术,经过新的真空压力浸渍工艺处理后的线圈与传统的处理方式比较有同样的机械强度和绝缘性能。此外,文中同时介绍了OH线圈层间接头的制造工艺,这是OH线圈的一个重要特征部件。 This paper deals with the electromagnetic analysis and engineering design of the OH coil for NSTX. In calculating the magnetic distribution and the inductance of OH coil, Bill-Surf equation and elliptic integral is used to simplify the calculation, Then , turn processes of calculation into language for computers , and a right result has been received after a series of adjustments. In engineering design , the 962 turn OH coil system consists of four layers which are wound“double-wire”, forming a total of 8 sub-windings which are electrically connected in series, but which are water cooled in parallel by 8 individual cooling paths. The conductor temperature and calculation of the velocity of cooling water flow are also given in this paper. In the OH coil the maximum voltages which appears between turns in the same layer is as high as 1.5kV. As the OH coil is very long and can not be placed in the vacuum pressure vessel, a new VPI processing technology is adopted for electrical Insulation of the OH coil. The coil after vacuum pressure impregnation has the same electrical and mechanical properties. Furthermore, the paper also show the fabrication of the OH Layer to Layer Joints ,which is the crucial feature of the OH coil.
