铝电解工艺特性要求系列直流电流尽可能保持稳定。当前,国内外铝电解整流装置及稳流方式通常延用有载调压整流变压器加饱和电抗器的机械——电磁式自动稳流方式,随着可控硅(晶闸管)硬件及其控制技术的不断发展完善,其电子无触点自动稳流方式的优越性,在工业实践应用中更加突出。国内大中型铝厂已有率先采用引进可控硅整流机组自动稳流装置的,实践证明,今后在铝电解工程中,逐渐推广可控硅机组自动稳流来提高电能质量在技术上和经济上是可行的。
Aluminum electrolytic process characteristics require series of DC current as stable as possible. At present, the domestic and foreign aluminum electrolytic rectifier devices and steady flow methods are usually extended with on-load voltage regulating rectifier transformer and saturable reactor mechanical - electromagnetic automatic steady flow way, with SCR (thyristor) hardware and control technology Continuous development and improvement of its electronic non-contact automatic steady flow of advantages, in the practice of industrial applications more prominent. Domestic large and medium-sized aluminum plant has taken the lead in the introduction of SCR rectifier automatic steady flow device, the practice has proved that in the future in the electrolytic cell project, the gradual popularization of thyristor automatic steady flow to improve power quality technically and economically It works.
