Audited Supplier summary
The FZW28-12F series outdoor boundary vacuum load switch is suitable for outdoor three-phase AC distribution systems with a rated voltage of 12KV and a rated frequency of 50H2, used for opening and closing load currents and closing short-circuit currents.
The FZW28-12F series outdoor boundary vacuum load switch is suitable for protection and control of substations, industrial and mining enterprises, urban and rural power grids, as well as automatic distribution networks of urban and rural power grids, as well as places with frequent operations.
The FZW28-12F series outdoor boundary vacuum load switch is an operational control switch used in overhead line distribution systems, with various types available. It has outstanding advantages such as oil-free, simple structure, reliable performance, and no need for maintenance, and has been widely used to this day. This product is combined with equipment such as FDR type fault detectors or RTU remote control terminal devices to form a very simple distribution automation system. It can achieve automatic positioning of overhead line faults and automatic isolation of fault sections. In order to update the existing distribution switchgear in our country and achieve the transformation of distribution equipment characterized by oil-free and automation.
Automatic locking of phase to phase short circuit fault: When the same short circuit fault occurs in the user's branch line, the boundary switch will immediately break off and lock after the substation circuit breaker or recloser protection trips. After the substation recloses, other branch users on the feeder line will quickly restore power supply;
Quickly locate the fault point: After the boundary switch protection action is caused by a user branch line accident, the responsible user loses power and proactively reports the accident information. The power company can dispatch personnel on-site to investigate the cause of the accident through a handheld computer or communication module;
Automatic removal of single-phase grounding fault: When a single-phase grounding fault occurs on a user's branch line, the boundary switch automatically opens, and other branch users on the substation and feeder line cannot feel the occurrence of the fault. This switch can achieve the following functions: quick break protection, overcurrent protection, triple reclosing analysis, event recording, anti surge protection, zero sequence protection, real-time clock, acceleration after reclosing, real-time status query, intelligent handheld computer control, local/remote setting of fixed values, active fault reporting, GSM short message function.
