Surge-free power automatic compensation device regulated pressure automatic reactive power compensation device, the device through real-time collection grid voltage, current, load trend analysis, system power factor, reactive power, harmonic content, voltage fluctuations cases, the use of fuzzy control technology regulator load tap dynamically change the voltage across the capacitor professional industrial cats, achieve compensation capacity varies with the system load reactive capacity of automatic tracking purposes. Henan Xi Connaught Electrical Equipment Ltd. is located in known as Chinese culture known as the axis of Zhengzhou City, the public railway network and improve the aviation network has created favorable conditions and opportunities for the company's rapid development. The company was formerly Suzhou Suoling Engineering Co., Ltd. (Zhengzhou Branch), founded in Henan Xi Connaught Electrical Equipment Co., according to market demand, the company main business scope covers passive harmonic control, active filter control, reactive power compensation, electrical engineering, power transmission engineering, electrical engineering, QD series vector inverter, QST soft start, mechanical and electrical equipment, electrical equipment, HVAC equipment, electronic equipment, lighting, hardware, wire and cable, fire-fighting equipment, such as construction, installation and commissioning. Current products and services have covered a variety of industries in Jiangsu, Zhejiang, Shanghai, Shandong, Henan, Shanxi, Hubei, Hunan, east, south, north, central, northwest and overseas regions. Hollow reactor performance standards GB10229-88 "reactor" DL462-92 "ordering technology with high-voltage capacitor series reactor" JB5346-1998 "series reactor" IEC289-88 "reactor" JISC4801-1997 "pressure and special high-voltage shunt Capacitor Series Reactor "works: the main route back down high voltage electricity H.APF ++ integrated active filter and reactive compensation devices connected reactors, circuit breakers, DC energy storage capacitors, IGBT module based on the converter, buffer and absorption circuit. By a three-phase IGBT modules connected in parallel to the parallel converter power line via a series Buck reactor. Load current through the main circuit CT is collected H.APF ++ control system, real-time detection circuit isolated by the load current reactive and harmonic components, application of large-capacity high-speed data processor DSP chip, using the latest technology PWM IGBT trigger control by adjusting the three-phase inverter AC side output voltage of the phase and amplitude of the industrial cats, simulate the load generated harmonic currents are equal in magnitude to sell industrial cat and opposite harmonic current injected into the grid, and load harmonic current cancel each other, to achieve harmonic filter function. If H.APF ++ is not only functional requirements but also at the same time filtering reactive power compensation function industrial product, H.APF ++ superimposed on a sinusoidal current at the output of the harmonic current waveform, and the load reactive current phase In contrast, the same size, the sinusoidal current phase and magnitude controlled, to inductive or capacitive reactive bidirectional continuous compensation. Sell ??Industrial cat, Xi Connaught Electrical and Mechanical (online consultation), industrial cats from Henan learning Connaught Electrical and Mechanical Equipment Co., Henan Xi Connaught Electrical Equipment Co. (www.hnxinuo.com) is Zhengzhou, electronics, electrical products processing leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In practice Connaught Electrical and Mechanical leadership with the staff warmly welcome all inquiries negotiations to create learning Connaught Electrical and Mechanical better future.
