南华大学船山学院毕业设计(论文)题 目 20kV 电力变压器设计— S11-1000/20 配电变压器电磁设计 专业名称 电气工程及其自动化 指导教师 指导教师职称 副教授 班 级 学 号 学生姓名 2013 年 6 月 3 日摘要:变压器自十九世纪问世以来,随着电力工业及供用电事业的不断发展,已经获得了极为广泛的应用。它是电力网构成中不可缺少的重要设备离开了它,随着生产技术的不断发展,变压器的型号、结构.性能与参数也在日益更新,这期间同样经历了一个相当的研制与发展过程。进而综观世界同行业的变化,更会激起我们树立奋勇赶超国际先进水平的雄心。本次是对 S11-1000kVA/20kV 的配电变压器的设计,设计通过对变压器的铁心直径的选择、线圈绕组的摆放型式与计算、导线的选择、损耗的计算、油箱尺寸的确定、绕组与油的温升等各个部分的计算,设计出一台符合设计要求的配电变压器。变压器是发、输、变、配电系统中的重要设备之一,它的性能、质量直接关系到电力系统运行的可靠性和运营效益,所以电力变压设计是一个很值得我们去研究的课题。关键词:变压器;铁心;线圈;损耗;油箱;温升;重量ABSTRACT:Since the transformer comes out since nineteen centuries, have already gained extremely broad application with power industry and the uninterrupted growth providing power consumption cause. It is that essential important equipment has left it in power network formation, with the technology uninterrupted growth , transformer type , structure function and parameter are also depended on gradually renewal , this period same have experienced one developing and development process suitable. The change making a comprehensive survey of the world and industry then, is able to raise us setting up the great ambition summoning up all courage and energy to catch up with and surpass advanced international level more. Time is the design to the S11-1000kVA/20kV distributing transformer originally , designs the calculation waiting for each parts by the fact that the pattern rises to transformer iron core diameter choice...
