超导托卡马克HT-7U磁体线圈模拟长样真空压力浸渍及低温力学性能

VPI FOR LONG MODEL OF SUPERCONDUCTING MAGNETS COIL AND ITS CRYOGENIC MECHANICAL PROPERTY

主要通过与低温超导托卡马克HT-7U中磁体线圈同截面的长样的真空压力浸渍(VPI)实验,探索线圈进行一次成形VPI工艺的可行性,掌握压力对浸渍的影响,为真实线圈的VPI工艺提供经验,并对固化后的绝缘层取样进行低温力学性能测试。

The feasibility of VPI(Vacuum Pressure Impregnation) of superconducting magnet coils of HT\|7U is testified by VPI experiment of long model. The section of the model is same as that of real coils. The parameters of vacuity and pressure are analyzed, which is the basis of the VPI technology of the magnet coils. The cryogenic mechanical property of sample that is made from the cured insulating layer of the long model is tested.\;
