Smart Diagnosis, Safe Control
Smart reclosing, remote circuit control, and autonomous power recovery for unattended sites.
Industry Challenges
& Solution Overview
In unattended scenarios such as communication equipment rooms, edge cabinets, distributed sites, underground facilities, and remote terminals, if a power system trips due to an instantaneous fault, it typically requires manual on-site intervention for recovery. This leads to long response times, high costs, and the risk of prolonged power outages for critical equipment.
This solution is based on terminal circuit breaker auto-reclosing and circuit-level control technologies. Within strict safety boundaries, it enables automatic recovery from transient faults and reliable lockout for persistent faults. This endows terminal power distribution systems with basic autonomous capabilities, significantly reducing reliance on manual intervention and improving power supply reliability in unattended environments.
High Costs from “False Outages”
High Risks in Remote Operations
No Local Decision-Making
Customizable Solutions
Auto-Reclosing
Activates automatic reclosing only for transient faults.
• Allows configuration of reclosing attempts, time intervals, and lockout logic upon failure.
• Automatically locks out after multiple trips or upon detection of a persistent fault, preventing repeated reclosing attempts.
• Reclosing actions are recorded and traceable for remote diagnostics.
Circuit Control
• Circuit breakers support electric open/close operations and status feedback.
• Local manual operation always takes priority to ensure on-site safety.
• Supports remote enabling/disabling of the reclosing function.
• Can integrate with gateways and monitoring systems to achieve "controlled operation, not blind operation."
