摘　　要：对ITER高性能氦气密复合材料轴向绝缘子的性能作了全面的试验测试研究分析,并简单的介绍了一下绝缘子的结构和工艺设计。试验测试结果表明:绝缘子能够承受室温到液氮温度50次冷热循环冲击,耐电压等级56kV、耐气压4MPa、耐拉压2000N、耐弯矩100Nm、耐扭矩100Nm的参数要求。绝缘子在电绝缘性能、机械性能、热冲击性能和气密性方面都能满足ITER磁体系统的技术要求。The performance of the ITER helium leak tight composite axial insulation breaks was tested in details, and the structural and process design were introduced. Test results show that insulation breaks can ensure 50 times thermal cycles from 300K to 77K, DC voltage at 56kV, inner helium gas pressure in 4MPa, 2000N in traction and compression, bending and torsion moments of 100Nm, which can be used to prove that the electrical insulation properties, mechanical properties, thermal shock resistance and air tightness of insulation breaks can all meet the technical requirements of ITER magnet system.
