一、前言 国内铝电解车间通常用电压小时计来计量电解车间及电解槽的直流功耗。但电压小时计仅仅是电压对时间的积累,而直流功耗值离不开电流量,因而电压小时计作为直流功耗计量可以说是间接的,缺乏直观性。 冶金部自动化研究院与黑龙江省佳木斯铝厂合作,用微机技术开发直流功? I. Preface The domestic aluminum electrolysis plant usually measures the DC power consumption of the electrolysis plant and the electrolyzer with the voltage hour meter. But the voltage hour meter is only the accumulation of voltage on time, and the DC power consumption value can not be separated from the current amount, so the voltage hour meter as the DC power consumption measurement can be said to be indirect, the lack of intuitive.
