    Product description
    YDX series anti-harmonic intelligent double circuits’ capacitor is a new generation of reactive power compensation equipment in 0.4kV low voltage power grid which have energy-efficient, line loss reduction,enhance power factor and quality and other functions.It consists of intelligent measuring and controlling unit,zore-crossing triggered switch,protection unit,filter reactor and low-voltage filter power capacitor.It changed the structure mode of traditional reactive power compensation device which was large and heavy. The new generation of low voltage reactive power compensation equipment have better compensation effect, smaller size, lower power consumption, cheaper price, more flexible use, more convenient maintenance, longer service life, better reliability and other features. It is suitable for the reactive power compensation with very serious harmonic.In this case,it could still reliable run,not produce syntony,not enlarge harmonic and absorb and eliminate harmonic to some extent.The equipment with 7% reactor applies to 5 and more harmonics’ electrical environment,and with 14% reactor applies to 3 and more harmonics’ electrical environment.Compared with single-circuit anti-harmonic intelligent capacitor,the double circuits’ capacitor have more capacity and takes up less space with the same capacity.
