The main object of the project is to build a nuclear fusion experimental device with divertor configuration, which is designed by the Institute of Plasma Physics, the Chinese Academy of Sciences (ASIPP). It is a full superconducting device, consisting of superconducting toroidal field (TF) coils and superconducting poloidal field (PF) coil. During the operation of the device, the operational parameter of device should be checked by technical diagnosis. This paper describes the design of circuit for checldng short between every two parts of the HT7U device.

文摘针对风电场建设中防火设计的关键性以及人工合规性检查存在的劳动密集、耗时易错等问题,自动合规性检查(Automatic compliance checking, ACC)的研究已广泛展开,旨在提供替代方案。为进行海上风电场设计工作中防火规则的共享与重用,本研究提出了一种基于工业基础类(Industry foundation class, IFC)标准和本体的海上风电场防火设计的合规性审查方法。该方法首先以规范中清晰条文为样本,对规范的约束性等级和防火控制方式加以分类以明确审查要点,探索建立海上风电场防火设计规范本体以规则化条文;接着,利用以IFC格式为海上风电场的建筑信息模型(Building information modeling, BIM)实现了模型数据的提取、扩展和转换,并与规范本体进行映射,实现异构本体间的语义互通和知识推理;最后,以海上风电场的BIM设计模型为例进行验证,构建了海上风电场防火设计ACC原型系统,为海上风电场防火自动化审查研究提供新的方法与手段。
