● Adopts dual-core 32-bit DSP microprocessor, with separate fast-switching core and HMI core.
● Uses real-time multitasking operating system and C++ programming technology, supporting online programming.
● Accurately measures switch closing time and automatically adapts to switch aging and replacement.
● Real-time system self-test on working power, AD status and memory status to ensure stability and reliability.
● Anti-interference design, compliant with the highest EMC levels, with software and hardware composite blocking architecture.
● Large-screen dual display (Chinese LCD and LED indication) for convenient on-site inspection.
● Excellent hardware interchangeability, facilitating user maintenance and reducing spare parts inventory.
● Adopts 6U, 19/3-inch standard chassis with rear plug-in structure, suitable for local mounting on switchgear or centralized panel installation.
Main Functions
● Suitable for two wiring schemes: incoming line and bus tie.
● Multiple starting modes: manual start, protection start, under-voltage start, false trip start, no-current start, reverse power start and abnormal frequency start.
● Functions including normal transfer, fault transfer and off-condition transfer (under-voltage, false switch trip).
● Three switching sequence options: parallel, series and simultaneous switching.
● Fast realization of fast switching, same-phase switching, residual voltage switching and long-time delay switching for both sides to be closed.
Auxiliary Functions
● PT wire break detection
● Standby power loss detection
● Switch abnormality blocking
● Closing loop time measurement
● Intelligent fault recording
● Holographic black box recording
● Device self-test fault alarm
● Intelligent transfer blocking identification
● Bus tie switch current protection (bus tie mode)
● Intelligent load shedding output (optional)
● Remote setting call and modification
