ABB RET670

Description

ABB RET670 is a powerful protection and control relay module.Here is a detailed introduction to it:

1.Product Overview

ABB RET670 belongs to ABB’s RELION series and is commonly used for protection,monitoring and control of electrical equipment and lines in power systems.It provides fast,selective protection for two-and three-winding transformers,autotransformers,step-up transformers and generator transformer banks.

2.Main functions

Power system protection:

RET670 can be used to protect generators,transformers,cables and lines in power systems from various faults such as overcurrent,overload and short circuit.

In power plants,RET670 can be used to protect generators,including monitoring and controlling overcurrent,overfrequency,overvoltage,etc.

It is used to perform differential protection and overcurrent protection on the transformer to ensure the safe operation of the transformer.The differential protection function features 2nd harmonic and waveform block suppression,as well as 5th harmonic suppression to avoid CT saturation and transformer inrush current tripping.

RET670 can be applied to the protection of cables and transmission lines to prevent short circuits,overloads and other electrical faults.

System monitoring and data collection:

RET670 provides monitoring and data collection functions for power systems,and can be used to diagnose,record and analyze the operating status of power systems.

Communication interface:

RET670 has a communication interface that can communicate with monitoring systems,SCADA systems or other automation equipment to achieve remote monitoring and control of the power system.

RET670 can be used with the IEC 61850-9-2LE process bus and can be equipped with up to six merging units(MU).

Integration into automation systems:

RET670 can be integrated into the automation control system of the power system to realize intelligent control of power equipment.

Provides advanced logic capabilities,allowing user logic to be programmed through graphical tools to implement special applications such as automatic opening of disconnect switches in multi-breaker arrangements,closing of breaker rings,and load transfer logic.

3.Application fields

RET670 is mainly used for the protection of power equipment,such as transformers,cables,generators,etc.,to ensure the stable operation of the power system.It is widely used in power systems,power plants,substations,industrial enterprises and buildings.

4.Product Features

Multifunctional protection:RET670 provides multiple protection functions,including overcurrent protection,undervoltage protection,overvoltage protection,ground fault protection,etc.These protection functions can be configured and customized according to the needs of different electrical equipment and motors.

Measurement and monitoring:Using advanced digital signal processing technology,RET670 can measure electrical parameters such as current and voltage,monitor and analyze changes in electrical parameters in real time,and accurately determine the operating status of electrical equipment and motors.

Fast response:The relay has a fast response speed and can quickly cut off the fault circuit when a fault occurs,preventing the fault from expanding and damaging the equipment,reducing power outage time and the risk of equipment damage.

Flexible configuration:RET670 supports flexible configuration and programming.Users can customize personalized protection solutions according to actual needs and the characteristics of the power system.

Remote monitoring and control:Supports remote monitoring and control functions,allowing operators to remotely monitor the status of the power system and perform necessary operations.
