ディストリビューション・オートメーション - 二次電源分配

設計上の考慮事項

By providing solutions and reference designs for secondary power distribution automation system reclosers, sectionalizers and ring main units (RMU), a number of challenges can be mitigated so that power outages can be shortened and system reliability improved significantly.

  • Recloser: A circuit breaker equipped with a mechanism that can automatically close the breaker after it has been opened due to a fault
  • Sectionalizer: A self-contained, circuit-opening device used to automatically isolate faulted sections of electrical distribution systems
  • Ring Main Unit (RMU): The automated measurement, monitoring, control and communications capabilities of Intelligent Electronic Devices (IED) within the RMU provide all the information needed to implement automated fault identification, fault isolation and power restoration
