Features
- It integrates various functions such as protection, measurement, monitoring, control, user interface, communication, etc. It is specially designed for the unitized design of the switchgear. One device can complete all the automation functions in the switchgear, simplifying the switchgear, replaces various relays and measuring instruments, saving a lot of installation space and control cables.
- Using a 32-bit digital signal processor (DSP) with advanced core architecture, high-speed computing power and real-time signal processing, the protection algorithms that were previously impossible due to CPU performance and other factors can be easily implemented.
- Support conventional RS485 bus (MODBUS communication protocol) and CAN field bus communication. The CAN bus has error correction mechanism such as automatic resend of error frames and automatic disconnection of faulty nodes to ensure the real-time and reliability of information transmission. The maximum rate is 1Mbps, the longest distance is 10km, and a bus can allow up to 110 devices to be connected.
- Fully enclosed metal chassis. The chassis is waterproof, dust-proof, and has strong anti-static, anti-electromagnetic interference and anti-mechanical vibration capabilities; it can be installed on the switchgear in a distributed way, or can be installed in a centralized group; the device structure is reasonable, easy to install and wire and debugging.
- Surface mount technology and important components (such as power module, transformer, relay, LCD, terminal, etc.) are all mature products of well-known enterprises at home and abroad, with an average fault-free time of 100,000 hours.
- Free of maintenance design, no need to adjust sampling accuracy on site, measurement accuracy will not increase error due to environmental changes and long-term operation, perfect self-inspection ability, and automatic alarm can be found for abnormal devices. With self-protection ability, effectively prevent permanent damage to the device caused by wrong wiring or abnormal operation; Maintenance free design, no need to adjust sampling accuracy in the field, measurement accuracy will not cause error increase due to environmental change and long-term operation.
- International common input power module, compatible with 85 ~ 265V ac or dc working power, even better in the power drop and voltage mutation has outstanding performance.
- The circuit breaker operating circuit is provided with an ac-dc general hardware anti-skip block module. The current size of the opening/closing operating circuit does not affect the normal operation of the module. The strengthened operation and management function of circuit breaker can be applied to all kinds of substations and distribution stations.
- Switch input supports direct tripping or alarm, for important protection such as gas, temperature or interlock tripping. Adopt the technology of setting the time window of the shift confirmation, effectively eliminate the switch contact jitter and electromagnetic interference, and ensure the accuracy of the remote communication is 100%.
- The user interface meets the ergonomic design requirements, with backlit graphic LCD, menu design, full display, and reasonable screen protection control. Display content includes measurement data, switch status, real-time waveforms, event logging, fault recording, protection settings, and system parameters.
