FZW28-12(FFK) series outdoor vacuum load switch is suitable for outdoor three-phase AC power distribution system with rated voltage of 12kV and rated frequency of 50HZ, as opening and closing load current and closing short-circuit current
FZW28-12(FFK) series outdoor vacuum load switch is suitable for substations, industrial and mining enterprises and urban and rural networks for protection and control, and automatic distribution networks for urban and rural power grids, as well as frequent operations
FZW28-12(FFK) series outdoor boundary vacuum load switch is used for operation control switch of overhead line distribution system. There are many types. With the outstanding advantages of no oil, simple mechanism, reliable performance and no maintenance, it has been widely used so far. This product is combined with FDR type fault detector or RTU remote control terminal device to form a distribution automation system with a very simple structure. It can achieve automatic positioning of overhead line faults and automatic isolation of fault segments. In order to update the existing distribution switchgear in China, it is necessary to realize the transformation of power distribution equipment featuring no oil and automation
Features:
1.Auto-locking phase-to-phase short-circuit fault: When the same short-circuit fault occurs on the user's branch line, the demarcation switch is opened and locked immediately after the substation breaker or recloser protection trips. After the substation recloses, other branch users on the feeder quickly recover power supply
2.Quickly locate the fault point: After the user branch line accident causes the demarcation switch protection action, the responsible user will cut off the power, and it will report the accident information on its own initiative. The power company dispatches personnel to check the cause of the accident through the handheld computer or communication module on the spot
3.The single-phase ground fault is automatically cut off: When a single-phase earth fault occurs on the user's branch line, the demarcation switch is automatically opened. The substation and other branch users on the feeder do not feel the fault
4.This switch can achieve the following functions: quick-break protection, over-current protection, three reclosing, event logging surge protection, zero sequence protection, real-time clock, post-acceleration acceleration, real-time status query, smart handheld control, local/remote setting Fixed value, active fault reporting, GSM short message function
