Mancheng County Ruixiang Electric Power Equipment Co

Equipment introduction> RⅠ type filter compensation device is mainly suitable for users whose power systems contain harmonics, with frequent load changes and large fluctuations. It is necessary to control harmonics, filter out high-order harmonics, and improve the power environment. At the same time, it is necessary to Compensating reactive power improves power factor for users. The R-type filter compensation device uses a microcomputer dynamic filter compensation controller. The filter branch uses a professionally designed filter reactor and capacitor bank to form a single-tuned filter. At the resonant frequency C, it can form an approximate short-circuit loop for harmonics. Characteristic harmonics are effectively filtered. The main circuit adopts the control method of power semiconductor thyristor contactless switch to switch the filter branch, automatic switching, and the filter compensation branch can be switched continuously and frequently without affecting the life of the switch and capacitor. The equipment has the characteristics of advanced technology, complete functions, high reliability, low maintenance and fast dynamic response. Quickly track system changes, perform filtering and compensation on-site, improve the user's power factor and harmonic conditions, achieve energy saving and improve user economic benefits. The device has a high degree of automation and can automatically exit work in the event of external failure or power outage, and automatically resume operation after power is supplied.
