    概述

    Reyrolle 7SR23 - Hochimpedanzschutz

    4xI

    Features

    The relay can be applied to busbars, connections, transbers, reactors and motors.

    The relay is used in ‘high impedance’ applications in conjunction with external stabilising resistors and non-linear resistors (Metrosils). Standardised external components can be provided in an Epsilon case to facilitate design and installation.

    The integral CT supervision feature detects open circuits in the CT secondary wiring circuits, a consideration where CT circuits are switched.

    Relays are housed in E6 or E8 cases. Integrated logic is provided to allow the optimal configuration of relay b and output functionality. Protection, instrumentation and metering functionality is accessible via data comms channels. A front fascia USB port for local connection and RS485 rear port for remote connection are provided as standard, additional rear ports are available as options.

    概述

    Reyrolle 7SR157 - Check synchronising

    2xV

    The Reyrolle 7SR157 Argus is a combined check and system synchronising relay designed to carry out controlled closing of a circuit breaker using measurements of the line and bus voltages.

    Features

    The relay will prevent the closure of a circuit breaker if the differences in phase angle, slip frequency or magnitude of the voltage falls outside prescribed limits.

    If the beters are within limits, the relay will issue an output which can be used to close the circuit breaker directly or in conjunction with an auto-reclose scheme.

    Housed in a 4U high, size E4 case, the relay provides instrumentation and fault data with integrated b and output logic, data logging and fault reports. Communication access to the relay functionality is via a front USB port for local PC connection or rear electrical RS485 port for remote Connection.

    Reyrolle 7SR224 - 4xI, 4/6xV, directional

    概述

    Reyrolle 7SR224 - Directional overcurrent protection

    4xI, 4/6xV, directional

    Reyrolle 7SR224 series relays include for directional control of three-phase overcurrent and earth fault functionality and typically installed as an integral controller for a pole mounted recloser. The controller offers an integrated auto-reclose solution for use on OHL feeders.

    Features

    The relay functionality allows highly flexible settings for current and time grading making it compatible with all types of overcurrent protection.

    Relays have four current and four voltage bs and are housed in E10 cases.

    Integrated logic is provided to allow the optimal configuration of relay functionality with the relays analogue bs and binary b/output circuits.

    Protection, instrumentation and metering functionality is accessible via data comms channel(s). A front USB port for local PC connection and rear electrical RS485 port for remote connection are provided as standard, additional ports are available as options.

    • Cold load settings
    • Eight settings groups
    • Password protection - 2 levels
    • User programmable logic
    • Self-monitoring
    • Circuit breaker trip counter and timer
    • Fault, event and waveb records
