Functions:
HD22020-2 is an overvoltage (current) protector, Mainly used to protect power systems, railway electrification systems, communication systems in various electrical equipment (transformers, switches, capacitors, stoppers, transformers, generators, electric power, power cables, etc.) from atmospheric overvoltage, current operating overvoltage (current) and power frequency transient overvoltage (current) damage.
It is the equipment that the substation is protected from the lightning shock wave.
It can also be used in the DC panel of the power distribution room or the module of the DC panel of the high voltage room for charging.
