compensatorSummary
HY series power Factor compensated controller takes the high performance SCM as the basic hardware,is made by the special control program for ten years service expe rience,because the computer high speed calculation capacity and logic judge capacity is adopted,this controller can realize the intelligence really.
Function characteristic
1.AC sample technology is applid for.
2.Digital integral,filter wave,no sensitivity to harmonic wave.
3.Reactive power as the control physical quantity,high control precision,without cut in and cut off shocking.
4.The control parameter is operated by digital, it is convenient to use,the data cant be lost when power off.
5.Adopts the auto optimized control scheme, to reduce the cut in and cut off times,it an improve the system service life.
6.Strong anti-interference,it can resist the 2000V interference pulse from power supply direct inputting,it cant loss the data until the machines is dead,so it is reliable and stable to run.
7.The number can display the power factor of power net,reactive power,voltage, current(measured by once),control parameter.
8.It has two modes of manual running and automatic running,it is convenient to operate and adjust for user.
9.It can judge and indicate the state of over voltage and under voltage,with the function of rapid cutting off the capacitor group,preventing the capacitor running under the over voltage.
10.It has the optional function of cut in and off shock closing(it is noted when user orders).
11.It has the optional function of single group capacitor delays for 200s from cut off time to cut in time,so it can have enough discharging time after the capacitor cutting off, and reduce the impaction to power net when the capacitor cuts in again (it is noted when user orders).
12.The input resistance of sample signal is less than 0.05Ωit can be got from the measuring loop.
13.It has the selection function of automation and manual.
14.The operation manual includes amounts of disposal methods of faults, user can install and adjust conveniently according to it.
