桥式整流电路与双反星整流电路对比系统研究大学设计毕设论文.doc

摘　　要 随着电力系统的日益发展，在高度现代化的今天，几乎在每一个领域都能直接地或间接地看到工业用的整流直流电源的巨大用途，整流变压器主要用在电化学工业。 因不同的整流电路需要不同的整流变压器设计，双反星带平衡电抗器整流电路和桥式整流电路相比，在同样负载直流电流下因其臂电流平均值是桥式整流电路的一半，且管压降也是后者的一半，因而被广泛用在低电压大电流系统中。但由于增加了平衡电抗器也增加了变压器复杂性和很多隐患，取消平衡电抗器三相五柱式整流变压器恰恰克服了平衡电抗器的缺点。 本论文研究的是就实际问题对比系统是采用桥式整流电路还是双反星整流电路应进行分析，平衡电抗器带来的隐患、缺点。以及取消平衡电抗器采用三相五柱式整流变压器设计的优点、理论基础，设计变压器计算单进行器件的选择,并绘制整体布置图。 作为一个实际的工程设计课题,论文所论述的大部分思想已经在实验室的实验中获得成功，实验结果表明该具有较好的性能。  Abstract With the growing power system development, at a height of the modernization of today, In almost every area can directly or indirectly, to see industrial use in DC power rectifier great purposes, rectifier transformers are used in electrochemical industries. Because of different rectifier circuits require different rectifier transformer design, dual-zone balance Reactor rectifier circuit and bridge rectifier circuit, the DC in the same load shedding his arm is the current average of the bridge rectifier circuit half, and the pressure drop is of the latter half, they have been widely used in low voltage high current systems. But due to the increase in the balance reactor has increased transformer complexity and many hidden problems. Canceled balance Reactor five three-phase transformer - rectifier is precisely to overcome the balance of Reactor shortcomings. On the question of research on practical issues contrast system is used bridge rectifier circuits or dual-rectifier circuit to be analyzed Reactor balance the implicit and shortcomings. And the cancellation of balance reactor using three-phase rectifier transformers five pole design advantages, the theoretical basis, Transformer design calculations for single device choice， and the mapping of the overall layout. As a practical engineering design issues, paper discussed by the majority of thinking in laboratory experiments to be successful, Experimental results show that the abolition of Reactor balance three-phase rectifier transformers-5 with a good performance. 目　　录 摘　　要
