| 摘 要： | 设计了HL-2M 环向场线圈基本形状、特殊的指形接头和斜面接头以及馈线、绝缘结构和水冷回路。每个环向场线圈由L 形中心段、上弧段和外弧段分别通过指形接头和斜面接头组装成完整的D 形线圈。分段可拆卸的D 形线圈结构可以使得真空室和单个极向场线圈分别整体吊装到环向场线圈内侧。单根引线和双回线的馈线结构既能节省装置空间，又能降低杂散磁场。TF 线圈匝间绝缘500V，对地绝缘30kV。采用软焊在线圈旁侧槽内的铜管对线圈进行水冷以带走线圈放电产生的焦耳热。

| Abstract: | The HL-2M TF coils shape, demountable joints, feeding & return bus, electrical insulation and cooling loop were designed. Each TF coil is assembled with L-shape center section, upper arc section and outer arc section, by finger joint and scarf joint to constitute complete D-shape coil. Demountable D-shape coils allow the vacuum vessel and individual poloidal field coils to be settled in the space within the TF coils integrally. The single feeding bus and two return buses located symmetrically, save the space and reduce the stray field. The TF coils are insulated electrically to 500V per turn and 30kV to ground. The coils are water-cooled using copper tubes soft-soldered into grooves in the sides of the coils in order to remove the Joule heat produced by the coils discharge. |
