试论空分生产中大型电机降压起动

Way of Large Electromotor Start by Steping-Down in Oxygen Production

随着社会发展和工业化程度的提高,大功率电动机的应用越来越普遍,从几千千瓦到几万千瓦,功率级别越来越大,然而大功率电动机的起动问题一直困扰着工程界。探讨了大功率电机起动的方法,并为今后制氧生产所需大功率电机提供了比较可靠的起动模式。

With the development of society and the increasing industrialization, large electric motors applications become more widespread, ranging from a few thousand to tens of thousands of kilowatt （kW） power level increasing, but the high start-up problems had plagued the electric motors engineering. How can reduce the impact of electric motors up to the grid and extending the useful life of the electrical have been discussed in the article and the way of solving has also been presented by the author.
