密炼机动态补偿跳闸自动报警功能改造

Modification of dynamic compensation of mixer automatic alarm tripping

密炼机驱动使用大型直流电机所配的晶闸管整流电路,是炼胶车间重要的谐波源,为治理其造成的谐波污染而采用的自动投切滤波器,该装置在实际运用中存在一定的局限性,本文就动态补偿装置微机保护功能如何同密炼机结合并及时提供预警信息的改造做出了阐述。

Thyristor rectifier circuit matched with large DC motor for mixer drive, is an important harmonic source of mixing room. Used to control the pollution caused by the harmonics, automatic cut filter has some limitations. This paper described the combine of computer protection of dynamic compensation equipment and the mixer, and the modification of warning information timely.
