一、提高功率因数的意义 电能的生产和应用,在国民经济中占有非常重要的地位,随着社会的发展,电能的应用将是极其广泛的。在工厂、企业中,由于采用一些感应电动机、电焊机、变压器等用电设备,电网除供给有功功率外,还必须供给大量的无功功率和无功电流,即供电设备输出的总功率中,既
First, the significance of improving the power factor The production and application of electric energy occupy a very important position in the national economy. With the development of society, the application of electric energy will be extremely extensive. In the factories and enterprises, due to the use of some induction motors, welding machines, transformers and other electrical equipment, the grid in addition to the supply of active power, it must also supply a large amount of reactive power and reactive current, that is, the total output power supply equipment, Both
