浅析石化行业电动机起动方式的选择与应用

Brief Analysis on Selection and Application of Motor Starting Mode in Petrochemical Industry

交流异步电动机的起动方法有全压和降压起动两种。全压起动最简单,但起动电流大;降压起动虽然起动电流有所降低,但投资增加,且增加了故障的可能。所以选择合适的起动方式尤其重要。

This paper presents two kinds of starting ways for AC asynchronous motor i.e.full voltage starting and reduced voltage starting.Full voltage starting is the simplest way,but the starting current is high;although the starting current of reduced voltage starting is reduced,the investment is increased,and the possibility of failure is increased too.To select the appropriate starting mode is especially important.
