Overview
The new high voltage DC circuit breaker is a kind of product based on the“Artificial intelligence zero crossing”converter technology. The new product perfectly solves the technical defects of the traditional high voltage DC circuit breaker, such as slow operating speed, long arc extinguishing time and so on.
Features：
Power system reliability
Through the“mechanical DC circuit breaker” technology, the abnormal power branch system is quickly disconnected.
Smart features
Product integration intelligent monitoring and automatic control functions, improve the level of intelligence of the system, can be real-time on-line monitoring.
Miniaturization
The design is more compact, takes up less space, and is conducive to system integration and layout requirements.
Smart operation
Intelligent diagnosis component state, the implementation is bad recovery.
