REU610CVVHCNN 电压保护继电器

1. DescriptionREU610CVVHCNN is a voltage protection relay for system voltageprotection, measuring and supervising in utility and industrialpower systems. REU610CVVHCNN is a member of ABB’s Relion®protection and control product family and part of its 610product series. The 610 series includes protection relays forfeeder protection, motor protection and general system voltagesupervision. The plug-in design of the 610 series protectionrelays facilitates the commissioning of the switchgear andenables fast and safe insertion and withdrawal of relay plug-inunits.

The protection relay is primarily designed for the overvoltageprotection of power system components, such as busbars,feeders, power transformers and capacitor batteries. It is alsoused for the general power system earth-fault supervision. Further, the protection relay can be used for undervoltageprotection of motors and overvoltage protection of capacitorbatteries, for initialization of automatic busbar changeover anddisconnecting small power units from the network in case of amajor network disturbance. The 610 series protection relaysare suitable for employment in marine and offshoreenvironments.

The numerical voltage protection relays of the 610 seriessupport a wide range of standard communication protocols,among them the IEC 61850, IEC 60870-5-103, DNP3, Modbus,Profibus, LON and SPA communication protocols.
