DYNAMIC POWER CAPACITOR BANK
This series of devices regard high-performance single-chip micro computers the basic hardware,adopt AC sampling, digital integration, filtration technology, can trace and compensate the reactive electricity intelligently. This method has prevented the problem caused when contactor input and cut off the capacitor, through compounding switch (input and cutoff mode of combining with crystal braking-tube and contactor ) and input and cutoff over-zero,so as to prevent the "surge current" caused while capacitor inputting. Three is no mechanical movement, and electric arc. No harm onic wave fast compensating speed that is especially suitable for using at the place of frequent inputting and cutting.And this method can lengthen the service life of the main device of capacitor. It has reason-able structure, modern techniques, mainly apples to the low-voltage power network to increase power factor and reduce reactive loss, improve power supplyquality. It is the new generation economizing on electricity products and also is one of the advanced compensator both at domestic and inter-national at present.
Main Characteristics
1.Small volume, convenient for installing and maintenace,good water proof performance, and can be used for both outdoor and indoor.2.Controlling parameter full digital operation, convenient for using, the data cannot lose when power off.3.Digital display power network power factor, reactive power, voltage, current (one side), control parameter.4.With the function of over-voltage, under-voltage judgment displays and fast cut off the compensated capacitor group.5.With two working modes of manual and auto compensation.6.It has the function of auto selecting the b est mode to input and cutoff compens ation according to the resultof capacitor group manual input.7.With two working modes of cycle or optimizing input and cutoff, the compensation Includes controlling mode of 1:1:1:1,1:2: 2:2, 1:2: 4:8, the compensator will automatically distinguish its code working mode of manual input duplexure capacitance value, it works according to the correspondence code mode.8.With two working modes of power factor or reactive powe r;9.Compensating mode:1) Phase splitting compensation 2)Phase splitting and three-phase compensation3)Three-phase compensation.10.Control mode:1) Crystal braking-tube in put and cutoff2)Compound switch input and cut off
