GGJ

The GGJ low-voltage reactive power intelligent compensation device adopts computer-aided design and introduces microcomputer control to intelligently track and compensate the reactive power.Its structure i reasonable and the technology is perfect.

Itis widely applied to the low-voltage power grid,which can improve the power factor,reduce reactive power loss, and improve the power supply quality. It is a new type ofpower-saving product.

Controlled by an intelligent controller, it has complete functions and reliable performance.The compensation mode is automatic. It can increase the power factor to above 0.9.

It can display the power factor of the power grid in real time, and the display range Is:lagging (0.00-0.99), leading (0.00-0.99).

It has a variety of comprehensive protection functions such as overvoltage,overharmonic,overcompensation,system failure,loss, overload, etc.

It can remember the set parameters, and the parameters will not be lost after the system power failure. After the power grid returns to normal, it will automatically enter the operating state without the need for personnel on duty.

According to the load balance situation of the power grid, it can adopt phase-by-phase compensation or mixed compensation. It has strong anti-interference ability and can resist the interference pulse with an amplitude of 2000V directlyinput from the power grid,which is higher than the national professional standard.

It can measure and record at every full hour the three-phase voltage,current,frequency,active power,reactive power,power factor,active electric energy,reactive electric energy at the low-voltage side of the transformer, the total distortion rate of voltage and current, and the harmonic content of the 2nd to 25th order. It has RS-232 and RS-485 interfaces, which can be used for data transcription by a palm computer.

It can also realize wireless meter reading,device testing,parameter setting,and reading of real-time measurement data and recorded data through the remote communication function. It has a data analysis function,which can analyze, process,count and query the operation load data.

It can comprehensively analyze the power supply quality,calculate the voltage qualification rate,power supply load rate, reliability rate and maximum load rate. It can query the power factor, active power and ractive power in different time periods. It can draw the curves of each phase voltage,current,power factor,etc.It can print comprehensive analysis and statistical reports.

Typus descriptio

Normalis servitium conditio

Temperatus aer ambiens non erit altior +40℃ nec humilior quam -5℃, et temperatura mediocris intra 24 horas non erit altior quam +35℃. His limitibus excessis, facultas operandi pro re ipsa detrahetur.

Usus umbraticis est et altitudo institutionis locatin 2000m non excedens.

Humiditas relativa aeris ambientis non excedet L% quando temperatura maxima est +50℃. In inferioribus temperaturis, humiditas superior relativa conceditur. Verbi gratia, 40% est + 90°℃. Influentia condensationis occasionalis a temperaturae mutationibus causata consideranda est.

Cum fabrica instituitur, inclinatio a plano verticali 5° non excedat, et tota coetus ordinum arcae relative planae erit. Fabrica instituetur in loco sine gravi vibratione et impulsu, et ubi partes electricae indebitae corrosioni non subicientur.
