摘要
交流异步电动机广泛用于工矿企业及民用系统,但不少异步电动机负荷率低,常处于轻载或空载状态,无功功率消耗比有功功率大,电能浪费严重。故对异步电动机采用就地补偿是提高功率因数、节约电能、减少运行费用的措施。本文对异步电动机就地补偿的作用、补偿电容器容量的选择、补偿接线方式等进行了论述。
Alternating current synchronism electromotor is widely used in enterprises and civil usage systems,but some of this kind of electromotor runs with a low payload,even if in a zero payload,which leads to a great waste of electricity.So a method of immediate compensation can be used to improve the rate of power and save the electricity,decreasing the costs.The rest of this paper goes on to discuss the issues,such as the effect of immediate compensation,how to choose capacitors and how to connect and other critical items.
