摘要
全数字直流调速装置的出现使得交流调速完全取代直流调速仍要经历一个较难的历程。现以攀钢烧结配料系统改造为例 ,介绍西门子 6RA70系列全数字直流调速装置在冶金行业烧结配料系统中的一种应用模式 ,以及为确保装置正常运行所采取的一些措施。
The advent of full digital-controlled convert ers for variable-speed DC drives makes it difficult for variable-speed AC driv es to take the place of variable-speed DC drives completely.This paper take th e example of the alteration of sintering ingredient system in Pangang Group,it presents one of the applying modes of the 6RA70 series full digital-controlled converters for variable-speed DC drives in metallurgy sintering and the measure sare taken to ensure the apparatus work safely.
