High Voltage Passive Power Filter Device Based on Controlled Reactor
General
 This device is a combined product of Shaanxi Electric Power Equipment Co., Ltd. and Tsinghua University joint research, development and production. The device mainly consists of filter capacitor, fixed reactor, controlled reactor, non-inductive resistance, electromagnetic contactors, thermal protection equipment etc. The capacitor capacity is designed according to  the fundamental frequency and required reactive power compensation; The harmonic frequencies and the capacitor can produce series resonance, and filtering devices in harmonic frequency form very low impedance, so that most of the harmonic current flow filter device, rather than through the main transformer. It is typical harmonic filtering and reactive power compensation equipment. Controllable reactor with advanced design and manufacturing processes, and apply a leading DSP digital signal processor control of reactor regulation. Device can automatically adjust inductance according to the load harmonic changes in real time, ensure the best filtering effect, color touch screen display offers a variety of parameters.
   Filter device is designed for customer needs and ensure optimum filter performance and characteristics of reactive power compensation, while increasing the efficiency of the user load, to achieve an effective return on investment.
Application
The products are mainly used in the metallurgy, electric power, petroleum, chemical and other systems.
Power filter device has the functions of filter and reactive power compensation, filter high harmonics, while improving power factor, simple structure, low cost, low operating costs, and can filter significantly inhibited to significantly reduce the harmonic content, up to the national standard.
Main features
