The New Research And Improved Arc-suppression Coil Reactor Based On Magnetic Flux Controlling

Most of China’s low-voltage grid system uses a small current grounding, which canimprove reliability, the most representative for the resonant grounded, the authors mainbody design, control strategies and other aspects of research.First of all, discusses the basic principles of fundamental magnetic flux compensation, bychanging one or two to change the port side of the current relationship between theequivalent impedance.Secondly, from the body structure and control of its two aspects of this comparison,analysis, improvement, introduction of new ideas and new body design of control strategies.Difficult to design not only simplifies the body, reducing the set of arc-suppression coilsystem cost and improve the body temperature is too high in the ground fault and theproblem of excessive noise, and improve the entire arc-suppression coil system response tofault the sensitivity and accuracy, thus further adjustable reactor to improve in the future toprovide more aspects of the use of valuable ideas and learn more.Finally, Matlab simulation tests related to specific projects and needs to improve thefeasibility and effectiveness, through prototype testing program to fully verify all aspects ofimproved performance enhancement, and briefly a few representative projects in thefunctional extension and application of the results achieved for a wide range of after marketadjustable reactor applications and lay the foundation for implementation.
