提高三角形接线异步电动机的功率因数

Raise Power Factor of Delta Connection Asynchronous Motor

本文主要介绍采用降低电动机运行电压的“Δ—Y”法,提高在正常工作时,三相定子绕组为三角形接线的轻负载运行的异步电动机的功率因数。同时对“△—Y”法能有效地提高轻负载运行的电动机的功率因数给予适当的理论分析。

The paper presents raising power factor of asynchronous motor of light load operating by the '△—Y'method of reducing motor operating voltage while function normalluy threephase rotor winding as delta connection, Furthermore the suitable theory analysis of the '△—Y'method of raising effectively power factor of light load operating is given.
