The FDL4-12/400 outdoor AC high-voltage sulfur hexafluoride automatic sectionalizer uses sulfur hexafluoride gas as the arc extinguishing medium and insulation medium. It is mainly used as a control and protection device in AC 50Hz, 12kV transmission lines, and can be coordinated with devices such as reclosers, circuit breakers, and fuses. When the load side line or equipment fails and the fault current reaches or exceeds the rated starting current setting value, the segmenter counts the disconnection actions of the backup protection equipment. When the counting times reach the set value, the segmenter automatically opens and closes to lock. The segmenter has the function of opening and locking state memory, and also has the function of automatic tripping with single-phase grounding of the busbar, without the need for external auxiliary power supply. Remote control of on-site opening and closing can also be achieved through RS485 interface to achieve three remote controls.

Structural characteristics of FDL4-12/400 outdoor column mounted high-pressure sulfur hexafluoride automatic segmenter:
1. Adopting electronic PT and CT float charging, and capable of AC220V charging.
2. Equipped with RS485 and RS232 communication interfaces and multiple communication protocols.
3. Implement the "four remote" functions, namely remote control, remote adjustment, remote signaling, and remote sensing.
4. Equipped with on-site remote control switch opening and closing function, with a remote control distance of 30 meters.
5. Set the tripping current anytime and anywhere, with flexible setting values and high functionality.
6. It has the function of suppressing current surge.
7. The microcomputer protection and measurement device is equipped with a set of 20 batteries, and the battery capacity can support 50 hours after a power outage.
