ZX5-400控制电路原理分析 摘 要 本论文题目为ZX5-400工作控制电路分析，主要分析了晶闸管弧焊整流器的结构组成，晶闸管弧焊机的详细电路原理，和各点的电流或电压波形，还对焊条电弧焊的工艺方法进行了介绍和分析。通过本次的论文，进一步了解了ZX5-400的工作原理，和对电路分析的基本知识，为以后的学习和工作奠定了基础。 ZX5-400晶闸管弧焊整流器广泛应用与直流焊条电弧焊及碳弧气刨。特别适用于碱性低氢型焊条焊接重要的低碳钢、中碳钢以及普通的低合金机构件。采用电流负反馈获得陡降的外特性，动特性好，电弧稳定，飞溅小，焊缝成型美观，有利于进行全位置焊接。电路中有电网电压自动补偿和过流保护环节，还有远控盒，可远距离调节电流。并且，还有引弧电流和推力电流装置，易于起弧不沾焊条。 关键词：ZX5-400工作电路；晶闸管；焊接工艺。 ZX5-400 Thristor rectifier arc welder Analysis Abstract In this paper, entitled ZX5-400 work in circuit analysis, the main analysis of the thyristor rectifier arc welding of structural components, welding machine thyristor circuit in detail, and the point of current or voltage waveform, but also on the electrode arc welding The processes were introduced and analyzed. Through this paper to learn more about the ZX5-400 of the working principle, and basic knowledge of circuit analysis, for future study and work laid the foundation. ZX5-400 thyristor rectifier widely used arc welding electrodes and DC arc welding and carbon arc gouging. Especially suitable for basic low hydrogen type electrode welding important low-carbon steel, medium carbon steel and low alloy bodies of ordinary matter. Current negative feedback was dropped outside of characteristics, dynamic characteristics of a good, stable arc, small spatter, weld shape appearance is conducive to all-position welding. Circuit voltage in the automatic link compensation and over-current protection, as well as distant control box can be remote-conditioning current. And, as well as current and thrust arc current device, easy to play non-stick electrode arc.
