家用电器功率因数初探

摘要

With the development of technology, the nature power factors of varioushousehold appliances are changed as well. On the basis of analysis of electronic rectifying circuit of capacitor filter, power factors of some household appliances with none pure resistance are measured actually with simple equipment and instrument, and accordingly, advises on the power factor value and reactive compensation of power loads in residence communities are proposed.%随着技术发展．众多用电设备的自然功率因数在发生变化。通过对电容滤波的电子整流电路进行分析，同时用简单的设备和仪表，对一些非纯阻性家用电器的功率因数进行实测。在此基础上对住宅小区用电负荷功率因数取值和无功补偿提出新的建议。
