Overview:
FZW28F-12 outdoor boundary vacuum load switch (FFK for short) is used in pole-mounted occasions and has manual and electric operation functions. The switch body is maintenance-free and uses vacuum arc extinguishing and SF6 gas as the insulating medium. This product complies with the following standards: GB3804-2004 3.6 ~ 40.5kV high-voltage AC load switch GB/T11022 Common technical requirements for high-voltage switchgear and control equipment standards This manual describes the structure, function and installation and commissioning methods of outdoor boundary vacuum load switches. FZW28F-12 outdoor boundary vacuum load switch has fault detection, protection, control and communication functions. It is installed on a 10kV line and can realize the self-cutting of single-phase grounding faults and automatic isolation of phase-to-phase short-circuit faults. It is suitable for the T-connection or user end of the user incoming line of the 10kV distribution line, and can also be used for other branch line connections that meet the requirements.
