REM615

REM615 is a special motor protection measurement and control device designed for the protection, control, measurement and monitoring of asynchronous motors in the manufacturing and processing industries. The REM615 is a member of the 615 Protection Measurement and Control Unit family in ABB’s Relion product family. The 615 series protection and control device has the characteristics of compact structure and easy disassembly.

The 615 series protection and control devices are developed and designed on a new platform according to the IEC61850 standard. This enables the product to fundamentally support features such as on-site device interoperability and horizontal communication without having to go through additional communication modules.

As long as the device is simply set up according to the specific application, it can be put into use directly. The 615 series protection and control devices support a variety of communication protocols, including IEC61850 (including GOOSE horizontal communication), IEC60878-5-103, and Modbus. 2, standard configuration

The click-protect measurement and control unit REM615 is available in four standard configurations. These standard configurations can also be modified by means of signal matrix or graphical programming in the PCM600 management tool for protection and control devices. Moreover, the application configuration tool supports the application of multiple logic function modules including delay and trigger modules to create multi-layer logic functions. The application of rich logic modules combined with different protection function modules, you can achieve a variety of special functional requirements of users.

3. Protection function

The protection measure and control device provides all the functions needed to manage motor start-up and normal operation, including alarm and fault detection in abnormal conditions. The protection measurement and control device mainly includes the functions of thermal overload protection, motor start time monitoring, rotor lock protection and frequent motor start protection. In addition, the protection measurement and control device also includes non-directional grounding protection, negative sequence current protection, overcurrent protection, loss of load monitoring, reverse protection and other protection functions.

Standard configurations B, C, and J also come with directional grounding protection, three-phase low voltage protection, negative sequence overvoltage protection, positive sequence undervoltage protection, overfrequency protection, low frequency protection, and frequency change rate protection.

RTD/mA input modules are available in standard configuration A and B. With the application of RTD/mA measurement data or analog GOOSE data, the multi-function protection module can be used for alarm or trip function.

The device can choose three arc protector sensor interfaces, when the arc fault occurs, the quick arc protection trip improves personal safety and reduces the damage to the switchgear.

4. Application

The REM615 can be used as the main protection for asynchronous motors and associated drives. In general, the motor protection can be used in a variety of applications: High voltage motors controlled by circuit breakers or contactors, and medium and large low voltage motors controlled by contactors in various drive devices such as pumps and conveyor belts, crushers and shredders, mixers and agitators, fans and ventilators, etc.

The magnetic balance current transformer can be used to realize sensitive and reliable grounding protection. Ground protection can also be achieved by the zero-sequence current synthesized by the external phase current. In this case, the internal interlocking function of the device or an appropriate steady-state circuit may be used to prevent misoperation of the motor ground protection due to CT saturation.

The optional RTD/mA measurement module in standard configurations A and B provides a maximum of 8 analog input signals: 6 RTD input signals and 2 mA input signals using a transmitter. RTD input and mA input signals can be used to detect the temperature of motor bearings and stator windings, thus extending the thermal overload protection function and reducing the aging speed of the equipment. In addition, the RTD/mA input can also be used to measure the ambient temperature, and send the GOOSE signal to other measurement and control devices for use, and can also receive temperature information from other protection and control devices through the station bus, thus expanding the source of relevant information.

In order to protect the safety of the power system and make the power system have a stable operating environment, the relay protection device is designed. Due to the rapid development of computer science, communication technology and information field, many new technologies have been applied and developed in digital protection equipment. Because of the characteristics of the embedded system of the protection device, its functions have become more and more comprehensive and complex, and the production cost and testing difficulty of the protection device have gradually increased. These changes have brought great challenges to the large-scale production and application promotion of the relay protection device.
Spontaneous and rapid processing needs to protect the fault and abnormal state of the equipment, and the purpose is to block the faulty equipment from the system, selectively acting on the circuit breaker, so that the equipment can work normally, control the loss in the smallest range, improve the reliability of the system, so that users can use electricity safely
