摘要
三相异步电动机耗电量占全国总用电量的60%以上。我国早在1990年就发布了GB 12497-1990《三相异步电动机经济运行》国家强制性标准,又分别在1995年和2006年进行了两次修订。1995版标准与2006版标准在三相异步电动机经济运行判别模型和电动机在偏离额定电压工作时对综合效率补偿方法有较大的不同。文章就上述两个问题进行了比较分析,并进行了实际测量。
Three-phase induction motors consume 60% of electrical energy in China. In 1990, China issued the mandatory national standard＂Three-phase Induction Motor＇s Economic Operation＂ and this standard was modified in the year of 1995 and 2006. 1995 and 2006 standards have quite differences regarding judgment of three-phase induction motor＇s economic operation and the method of comprehensive efficiency compensation due to motor＇s operation voltage away from the rated voltage. This paper compares and analyses the differences, and some measurements have been made.
