ABB REF615The ABB REF615 is an intelligent electronic device (IED) specifically designed for public substations and industrial power distribution systems. It supports the protection and control of radial, loop, and mesh distribution networks. Its core functions include primary protection (such as for overhead lines and cable feeders) and backup protection (redundant systems), and it achieves communication interoperability based on the IEC 61850 standard. This product features a compact, withdrawable design, facilitating easy installation and maintenance, and is widely used in the power, industrial automation, and public facilities sectors.Input voltage: 100-240V AC/DC (some models support DC input)Output voltage: 24V DC (for control circuits)Maximum load current: 5A (control circuits)Communication interfaces: Supports protocols such as IEC 61850, Modbus RTU/TCP, DNP3.0, IEC 60870-5-103, etc., equipped with Ethernet, RS485, and other interfacesOperating temperature range: -25℃ to +70℃ (some models extended to -20℃ to 50℃)Protection rating: IP40 (panel IP52)
Product Features
Multifunctional protection: Provides overcurrent (50/51), ground fault (67N/51G), thermal overload (49), voltage abnormality (27/59), frequency protection (81), etc. It supports instantaneous/intermittent ground fault detection and three-phase multi-stage automatic reclosing.Modular design: Supports plug-in units (including protection + measurement functions) and optional modules (such as arc protection interfaces, IO expansion modules), facilitating upgrading and expansion.High reliability: Adopts a modular structure with strong anti-interference capability, MTBF > 100,000 hours, and has passed certifications such as KEMA and UL.Communication compatibility: Supports GOOSE subscription, enhanced network security (IEC 62351), and can be integrated with the ABB Ability™ platform to achieve remote monitoring and diagnosis.
Structure and Composition
Hardware Composition:
Plug-in units: Include protection logic, measurement modules, and communication interfaces, supporting quick plugging and unplugging.Enclosure: Made of high-strength plastic material, providing options for embedded, panel-mounted, or cabinet installation. The panel opening size needs to be adjusted according to the installation method.Additional modules: Optional generator excitation cards, synchronization check modules, etc., to meet complex control requirements.Human-Machine Interface (HMI): Equipped with a large-size LCD display, supporting graphical operations (such as single-line diagrams, event records), parameter settings, and remote access (Web HMI supports IE7.0-9.0 browsers).
Application Fields
Power systems: Substation feeder protection, bus section protection, transformer backup protection, and power plant equipment protection.Industrial fields: Power distribution systems in industries such as cement, metallurgy, petrochemicals, automobiles, and papermaking, as well as protection and control of motors and large-scale equipment.Public facilities: Power distribution networks in municipal, airport, port, real estate, and other fields, supporting the access of distributed energy sources (such as photovoltaics, wind power).
Installation and Maintenance
Installation methods:
Embedded/panel-mounted: Suitable for installation on the panel of power distribution cabinets, requiring reserved opening sizes (e.g., 100mm×80mm).Cabinet installation: Supports 19-inch standard racks, facilitating centralized management.
Debugging and configuration:
Use the ABB PCM600 software for parameter setting, logic programming, and fault recording analysis (sampling rate 4kHz).Supports remote diagnosis and event recording, facilitating quick fault location.
Maintenance suggestions:
Regularly check the cleanliness and tightness of input and output interfaces to ensure stable communication links.
