HLY-J/X arc suppression and elimination harmonic and overvoltage suppression device

Device for 3 ~ 35kV neutral point non effective power system, the system running in all voltage limits, especially on resonance over voltage and single phase arc grounding over voltage limit and eliminate, the device also provides sensitive and reliable single-phase grounding protection, to effectively improve the power grid running safety and reliability of power supply.

Main function:

1 this device has three voltage transformers, providing voltage monitoring function.

2 can replace the Petersen coil, eliminate the intermittent arc grounding, permanent metal arc grounding fault.

. in a control software additionally with a computer harmonic elimination, due to the over voltage caused by Pt ferromagnetic resonance, because the system to ground capacitance storage of charge discharge caused by Pt ferroresonance, fault disappears after the PT ferroresonance can limit and eliminate.

4 the device contains small current grounding line selection function, can be sensitive and accurate to elect a single phase grounding line.

5 with a limit of lightning over voltage, over voltage and phase function.

6 JXY-J/X arc suppression and over voltage suppression device with RS485 and RS232 communication interface, remote data transfer can be achieved.
