The Application Of Heavy-current Silicon Rectifier Assembly In The Chlorine And Alkali Industry

With development of power electronics technology and advancement of heavy-current silicon rectifier assembly's application technology - mainly been used in electrolysis power supply of electrochemistry industry, some new demands have been put forward for design and manufacture of heavy-current silicon rectifier assembly. Same phase inverse parallel connection's three-phase bridge thyristor rectifier assembly was researched mainly the application in the chlorine-alkali industry. As the working current of this assembly is very big, concomitant electromagnetic wave, harmonics and so on can't been neglected. In addition, each rectifier arm was made of many thyristors that are parallel connection, so there had the problem that current was distributed equably, in the same way, current-sharing coefficient was a vary important technology index.In this paper, it did simulation experiment and tested in the locale for quick-fuse, generatrix temperature and current-sharing coefficient. Moreover, it did research on control arithmetic for temperature control system and did system simulation. And to discuss comparatively detailedly harmonic's produce, harm and restrain.The set of equipment has been run in the locale, its running result proved further its design to accord completely with the working demand of locale and realized the technology index of design.
