    Get PDF
    大容量试验是检验电力装备性能,保障装备安全可靠运行的重要环节。现有的大容量试验回路主要依靠人工操作,存在流程复杂、效率低且易出错的问题。针对大容量试验回路智能化控制的难题,研究建立了冲击发电机单电机短路模型和双电机并联短路模型,分析了发电机短路特性,结合典型大容量试验回路设计了一键顺控方案,提出试验回路一键顺控操作流程。通过对发电机短路模型和大容量试验回路系统的仿真,验证了所建发电机短路模型的正确性及大容量短路试验一键顺控方案的合理性

    作者简介: 张小玲(1959-),女,厦门市消防支队 防火处高级工程师,主要从事消防监督管理工作, 福建 省厦门市湖滨北路119 号, 361012。[中文文摘]通过对主粘结剂、聚合物改性剂、骨料和无机阻燃剂等因素的研究,得到改进的常规厚涂型防火涂料,在其表面涂覆纳米插层氨基树脂以改善其耐腐蚀性。以原位插层法制备了蒙脱土/氨基树脂纳米复合材料,采用X射线衍射(XRD)、断面扫描电镜(SEM)及透射电镜(TEM)研究了其分散形态。试验表明通过表面涂覆改性得到的隧道防火涂料组合物具有良好的耐腐蚀性和耐火性能。[英文文摘]Via the investigation on factors such as main adhesive, polymeric modifier, bond materials and inorganic fire retardant, the performance of thick coated fire proof coating is improved. Surface modification by nano-intercalation amino resin improves the anti-corrosion property of the fire proof coating. The montmorillonite/amino resin nano-meter composite is made by the method of in-situ intercalation, and its dispersion morphology is analyzed by XRD, SEM and TEM. The experiments prove that the nano-intercalation amino resin modified fire proof coating performes well in fire proof and anti-corrosion
