FZW28A-12/630-20 vacuum load switch, segmenter
The FZW28A-12/630-20 intelligent segmenter and demarcation switch adopt maintenance-free design. The vacuum arc extinguishing and SF6 gas are used for the insulation between the ground and the phases, which has excellent breaking performance and sealing performance. It can be used together with FAICMWD-LBS intelligent segment controller to realize various protection functions such as overvoltage, undervoltage, phase loss, single-phase grounding, wire breakage, and high impedance grounding.
When FZW28A-12/630-20 intelligent segmentation device is installed at the segment of the 10kV feeder, it can cooperate with the intelligent recloser. When a short-circuit fault or a single-phase earth fault occurs on the line, it can quickly and automatically isolate the fault zone to the maximum. To restore power to non-faulty sections.
When the FZW28A-12/630-20 intelligent segmenter is installed at the branch, it can realize automatic isolation of a short-circuit fault or a single-phase-to-ground fault accident on the branch line or the user side, reducing the scope of power outage.
The device can not rely on communication, and the intelligent recloser and the intelligent segmentation device can automatically cooperate to realize the automatic recloser VIT feeder line.
