Recently, the world's first bipolar bidirectional marine 10 kV medium voltage DC hybrid circuit breaker successfully passed the high current short circuit breaking test. The 10 kV voltage rating is equivalent to 45 times the electricity consumption of ordinary residents, and is currently the highest voltage level for marine power systems. This major breakthrough not only filled the technical gap in the field of marine medium voltage DC circuit breakers, but also marked that China has achieved a key technological breakthrough in the field of marine power equipment and is leading the way in global innovation. According to reports, the equipment was independently developed by the 704th Research Institute of China Shipbuilding Group.
