一、概述 根据目前国内造纸机可控硅传动存在的问题及国内外电气传动发展的情况,特别是当前国家需要大力发展大型高速造纸机,又对电气传动提出了更高的要求,为此,有必要对以往的造纸机可控硅传动系统加以改进提高。 在轻工业部的组织下,我们于1973年8月对国内造纸机可控硅传动进行了调查、分析,并参考了国外造纸机可控硅传动有关资 I. Overview According to the current domestic paper machine SCR drive problems and domestic and foreign electric drive development, especially the current need for the country to develop large-scale high-speed paper machine, but also put forward higher requirements for electric drive, therefore, It is necessary to improve and improve the past SCR drive system of paper machine. Under the organization of the Ministry of Light Industry, we conducted a survey and analysis on the SCR of the domestic paper machine in August 1973, and made reference to the overseas investment in SCR-related transmission of paper machines
