Description
ABB REF542PLUS is a multifunctional protection and switch control device.The following is a detailed introduction to it:
1.Product Overview
ABB REF542PLUS integrates all auxiliary functions of protection and switchboard control,suitable for feeder,transformer and motor protection and control,or only for switchgear control.It has an impressive range of protection and management functions,and can flexibly adjust the device configuration according to the intended application.
2.Main functions and features
Real-time multifunctional protection and switchgear control:
Provides fault location,measurement,control,monitoring and diagnosis functions.
With power quality functions and communication capabilities.
It can realize the task separation of protection and control scheme modification,as well as the separation of human-machine interface and basic unit,and the installation is flexible and changeable.
Monitoring and self-diagnosis:
Provides a variety of functions for monitoring primary equipment and self-diagnosis.
The maximum and average currents,the sum of interruption currents,operating time,number of switching cycles,spring charging time monitoring,etc.during the observation period(0~30 minutes)can be calculated and displayed.
Equipped with a self-diagnosis program to continuously check the status of hardware and software modules.
Binary Input and Output Modules:
Each module is equipped with a watchdog contact that is triggered in the event of a fault or power failure to detect equipment failure and initiate appropriate measures.
Analog Input Modules:
Can be used to connect external process signals such as primary current and voltage signals.
Optional analog input modules(420mA)and analog output modules(0/420mA)are available.
Human Machine Interface:
Equipped with a large multi-language LCD display for displaying single-line diagrams,text information and menu texts.
Protection scheme parameters can be changed via the human machine interface control unit without the need for a PC.
Communication and Integration:
Optional communication modules are available for substation automation systems.
Equipped with an Ethernet interface for embedded web servers and an optional optical input port for time synchronization.
Logic and Control Schemes:
A wide range of logic functions are available,such as AND,NAND,OR,NOR,XOR logic gates,as well as bistable and monostable flip-flops.
A wide range of required control schemes can be configured,including interlocking of switchgear,preventing the release of specific protection functions,and initiating switching sequences.
