浅析提高功率因数的意义及方法

摘要

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 reac-tive power is asynchronous motors and transformers. It also ex-pounds that the improvement of power factor can save power ca-pacity, reduce low-line consumption and improve the utilization of power supply equipment, and then proposes methods to im-prove power factor.%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。
