摘要
根据功率因数的特性,本文介绍了致使功率因数过低的主要原因,指出电路中消耗无功功率的主要设备是异步电动机和变压器。阐述了提高功率因数可节约电源容量、降低线路损耗、提高电源设备的利用率,并提出了提高功率因数的方法。
In accordance with the properties of power factor, this paper introduces the main reasons causing exceedingly low power factor, and points out that the main equipment consuming reactive power is asynchronous motors and transformers. It also expounds that the improvement of power factor can save power capacity, reduce low-line consumption and improve the utilization of power supply equipment, and then proposes methods to improve power factor.
