Reyrolle 7PG17

The range comprises electro-mechanical relays for a range of auxiliary and tripping functions. Various combinations of coils, contacts, operation indicator flags can be specified. Options are also available for operate and reset modes. 7PG17 XR relays - Interposing relay for control applications, supply supervision, trip circuit supervision, ferroresonance alarm.


Features

  • Interposing Relays:
    The interposing relays are intended for the remote control operation of switchgear over pilot wires with a maximum resistance of 200 ohms. The relays are designed so that they are not susceptible to certain a.c. voltage levels which may be induced onto the pilot wires.
  • Supply Supervision Relays:
    The supervision relays are designed to monitor DC Voltages. They have a low operating current, specific settings, time delayed drop-off, a mechanical flag indicator which shows on de-energisation and contacts for the ability to initiate remote alarms.
  • Trip Circuit Supervision Relays:
    These relays are for the monitoring of the circuit breakers trip circuit to ensure integrity at all times. There are differing preferences for monitoring a trip circuit and our range is designed to meet these requirements.

Functions
  • 7PG173 ??? Interposing Relays
    Type XR205 and XR206 are two element versions of the XR105 and XR106 respectively with the same performance. Type XR105 has no flag indicator, XR106 and XR107 have a hand reset flag. Both types are available with a suppression diode across the coil to reduce the effects of the back emf which occurs on switch-off. 
  • 7PG1751 ??? Trip Relay Supervision
    Type XR151 relays are designed to allow the supervision of a trip relay operating coil, supply and associated wiring. 
  • 7PG174 ??? DC Supply Supervision Relay
    Types XR152 and XR153 relays are designed to comply with CEGB and other specification for protection supervision requirements and the monitoring of d.c. voltage supplies. These applications require relays with low operating current, visual indication and the ability to initiate a remote alarm. 
  • 7PG175 - Trip Circuit Supervision
    XR250 and XR251 circuit breaker closed supervision will initiate an alarm and provide indication with the circuit closed for: Failure of the trip supply, open circuit trip coil, an open circuit in the trip circuit wiring and if the trip coil should fail to respond to a trip command. 
  • XR350 and XR351 provide continuous supervision with the circuit breaker in the open and closed positions and in compliance with the scheme requirements of BEBS S15 scheme H7. XR350 and XR351 relays also have a contact for pre-closing supervision, where a circuit breaker is prevented from being closed if trip relays have not been reset. BEBS S15 scheme H7 is applicable to trip circuit voltages of DC 125 V and DC 240 V.

Features

The features of the High-speed trip relay are:

  • High-speed, high burden, positive action, and instantaneous cutoff.
  • The 7PJ1521 & 7PJ1524 trip relay can be used with the Trip Circuit Supervision relay (7PJ13) to monitor and supervise the integrity of the trip circuit with coil supervision terminal.
  • It is supplied in a draw-out type case.

Functions

The high-speed trip relay type 7PJ15 is mainly used for all types of control and protection circuits in power stations and industrial applications, where a higher grade of reliability and high contact rating is stipulated. The 7PJ15 relay acts as a high-speed element and contact multiplication in tripping and signalling circuits of protective relays.

 

The high-speed trip relay is used in the following applications:

  • Tripping of multiple circuit-breakers
  • Tripping and lock
  • Control signalling and interlocking
  • Inter tripping and remote tripping interface for SCADA

Reyrolle 7PG15

The range comprises electro-mechanical relays for a range of auxiliary and tripping functions. Various combinations of coils, contacts, operation indicator flags can be specified. Options are also available for operate and reset modes. 7PG15 TR relays - High-speed multi-contact tripping relays, available in both high and low burden models. Variants up to 11 contacts, <10 ms operation.


Features

Type TR relays are a range of multi-contact attracted armature relays complying with IEC 61850. A wide range of models is available to meet the requirements of the electric supply industry. High speed, positive action can be supplied in modular and a withdrawable type case. Robust design for a long, reliable service life. Available with up to 20 contacts.


Functions

  • Low burden, TR1 series Type TR1 relays are suitable for application for tripping and auxiliary duties where immunity to capacitance discharge is not required. These relays are not intended for use with current operated series follower relays. 
  • High burden, TR2 series High burden relays with immunity to capacitance discharge currents. They are also suitable for certain applications where they are remote from the initiation signal. A high burden also permits reliable operation of current operated series repeat relays. TR relays can be provided with an instantaneous or time-delayed cut-off.
  • Low burden relay, TR312 Designed to meet the requirements of NGC specification P15, this is an electrically reset relay (no flag indicator) with additional terminals in the economy circuit to enable a direct connection to the dc supply. This arrangement allows a reduction in the break duty of the initiating contact. 
  • Switching Relay, TR431 Designed to meet the requirements of NGC TDM 5/11, this is an electrically reset relay with a flag indicator which follows the contact operation. These relays are intended to switch protection and auto reclose equipment in and out of service when controlled over pilot wires from a remote point. They are intended to operate from a remote 50V d.c. battery with a pilot loop resistance of up to 200 ohms.
