Electrically isolating surge arrester KAD-GGF

Based on the "Supplementary Documents for Secondary Lightning Protection and Network Isolation Renovation in Substations"-Transportation Equipment announcement No. 240 and "Opinions on Optimizing Technical Solutions for the Secondary System of Traction Substations Against Strong Electricity Intrusion"-Transportation equipment announcement No. 325 standard, isolation lightning protection screen is carefully designed and professionally manufactured into an independent emergency protection device. The isolation lightning protection screen is a screen cabinet for installing an isolation transformer and a surge protector (SPD) between the AC screen of the traction substation and the outdoor overhead lines isolation switch mechanism box. Providing AC power to the overhead lines electric isolation switch, the isolation transformer feeder circuit realizes the discharge and isolation of the surge voltage invaded by the outdoor overhead lines isolating switch power circuit, preventing the transfer of high level outside the station from entering the AC screen of the traction substation, thus the safe operation of substations will not be affected. KAD-GGF isolation lightning protection screen adopts professional, high-quality isolation transformer and comprehensive grounding technology design to minimize lightning hazards, improve protection effects, and protect equipment to operate safely and reliably in the long run. KAD-GGF isolation lightning protection screen is suitable for the isolation of the AC power circuit and the protection of over-voltage and over-current from lightning in the substation overhead lines isolation switch.
