3. Product Features
- Scalable Functions and Flexible Configuration: Supports a variety of preset configurations, and functional modules can be added or removed according to user requirements.
- Multiple Protection Functions: Including directional earth fault, maximum current, thermal overload, phase unbalance, phase-to-phase short circuit, etc.
- High-Speed Fault Location: Suitable for radial, ring and mesh distribution structures.
- Rich I/O Interfaces: 8 RTD/mA inputs, 4 analog outputs and 6 digital outputs to meet complex on-site requirements.
- IEC 61850 Compatibility: Supports horizontal messaging such as GOOSE and MMS to achieve substation interoperability.
4. Structure and Composition
- Main Unit: Can be installed in 19-inch relay cabinets, wall-mounted or semi-flush enclosures.
- Front Panel: Equipped with a graphic LCD screen, function keys and programmable buttons, providing a local operation interface.
- Communication Module: With Ethernet/fiber optic interfaces, supporting IEC 61850, DNP3 and IEC 60870‑5‑103 protocols.
- Power Module, I/O Module and Protection Logic Module: All adopt pluggable design for convenient on-site maintenance and upgrading.
5. Application Fields
- Primary protection for feeder lines in distribution networks (overhead lines and underground cables)
- Radial, ring and mesh distribution systems
- Distribution networks with/without distributed generation
- Industrial power distribution rooms and substation automation
6. Installation and Maintenance
- Installation Method: Can be embedded in 19-inch cabinets, semi-flush mounted or wall-mounted, adapting to different on-site spaces.
- Wiring: Provides complete wiring diagrams, supporting the connection of multiple circuit breakers, disconnectors and earthing switches.
- Maintenance: The modular design facilitates on-site replacement; status monitoring, fault diagnosis and parameter adjustment can be carried out through the built-in HMI or remote SCADA system.
- Environmental Requirements: Operating temperature ranges from -25 °C to +55 °C, storage temperature ranges from -40 °C to +85 °C, and the protection level meets the conventional requirements of power distribution rooms.
