REJ601 专用馈线保护继电器

Entry-level numerical relay for distribution networks
REJ601 is a dedicated feeder protection relay intended for the protection of utility and industrial power systems in primary and secondary distribution networks. The relay provides an optimized composition of protection and monitoring functionality in one unit, with the best performance and usability in its class.

Besides the conventional current transformer interface based variant, the relay also supports a variant based on Rogowski current sensors’ analog interface. This helps to obtain a compact medium voltage switchgear equipment size reduc­tion with improved performance and standardization.

Scope
Main protection for overhead lines and cable feeders in solidly earthed, resistance-earthed or isolated networks
Inrush current stabilization function for distribution transformers

Product benefits
Compact, flexible and simple to handle
Speedy commissioning through selective test function for protection functions, binary signals and communication features
Easily configurable binary inputs and outputs
Extensive self-supervision of the relay hardware and software
Enhanced safety with usage of sensors variant / detachable terminals with CT shorting facility
Press fit mounting arrangement facilitates easy and fast installation

Product features
Overcurrent, earth-fault, phase-discontinuity, negative-phase sequence and thermal-overload protections, inrush current detection, reclosing and measurement
Preconfigured functionality facilitates easy and fast commissioning
Universal power supply 24-265 V AC/DC
Configurable binary inputs/outputs using local HMI or communication interface
Specific variant with site selectable CT selection (1 or 5A), Boolean logic and timers
Supports Modbus and IEC 60870-5-103 protocols
