Outdoor Pole Mounted High Voltage SF6 Automatic Partition Slotter
Introduction - Automatic Partition Slotter [Electrical Switch]FDL4-12/400Outdoor Pole Mounted High Voltage SF6 Automatic Partition Slotter adopts SF6 gas as the arc chamber and insulation media.
It is mainly used in the three-phase AC 50 Hz 12 kV rated voltage transmission circuit as the control and protection equipment. It can be used with recloser, circuit breaker and fuse. If the load side circuit or the equipment breaks down, the failure current reached or exceed the rated starting current setting value, the partition slotter would count the break actions of the reserved protection equipment. Once the counted number reaches the setting value, the partition slotter will automatically open the switch and lock it.
The partition slotter has lock state memory function and can automatically skip the switch with the connection to single phase generatrix without other auxiliary power supply. It can carry out opening and closing remote control on the spot as well as connected to RS485 interface which achieves three remotes.
