概览
当用于保护架空配电变压器的熔断器运行时，70%的情况下属于瞬时故障，无需额外检修工作。这意味着企业需要为完全可以避免的问题承担不必要的维修成本。
VacuFuse II自动复位开关可取代架空变压器上的传统熔断器，有效防止误动停电。这一现代化解决方案提升了电网的可靠性和弹性，同时降低成本并优化配电网运营。
优势
Experience Even More Benefits with Fault Testing
Consider the VacuFuse II interrupter fault-testing model to keep temporary faults from causing sustained outages—and improve reliability in hard-to-reach areas.
EXPLORE FAULT-TESTING BENEFITS结构
Vacuum Interrupter
Sealed chamber opens quietly to extinguish arc without expulsion of debris.
Electronic Controls
Electronic controls avoid unexpected outages by not accumulating fuse damage.
TCC Curve Variety
Vast library of TCC curves makes coordination with upstream devices easy.
TCC Curve Shift Protection
Permanently accurate TCC curves are unaffected by overcurrent events.
Cutout Installation
Device installs into a cutout using standard utility tools and procedures.
Easily Resettable
Device is easy to reset after operation with no re-fusing required to prevent errors and reduce inventory.
Drop-Open Visible Gap
Device locks and drops out to indicate fault status, improving fault-finding.
Delayed Close
Automatic time-delay gives crews time to move away before the vacuum interrupter closes.
