摘要
公司2台整流变压器低压侧接有2台密炼机,实测电网功率因数低,且谐波严重。为此决定采用动态滤波补偿装置,既可有效吸收电网的3、5、7次谐波,又可进行无触点投切运行。改造后,功率因数达到0.96,年节约资金60余万元,不到1年就收回投资。
The low-voltage sides of 2 rectifier transformers connected with 2 mixers, the actual measurement of power factor was low and harmonic was serious. Therefore, by using dynamic filter compensator, not only can effectively absorb the power grid harmonics 3, 5, 7, but also use for noncontact switching operation. After the transformation, power factor can achieve 0.96, annual savings of 60 millions RMB, and the investments can be recovered within one year.
