Many recloser controllers currently in operation suffer from low intelligence; they lack real-time status monitoring, diagnostic traceability, and often have cumbersome user interfaces. This makes troubleshooting slow and labor-intensive, driving up O&M costs. Based on a real-world urban distribution case, we have developed a specialized solution to resolve these operational bottlenecks.
I. Pain Points: High Costs and Slow Response Times
Core Issues
No Status Monitoring: Inability to track temperature, voltage, or current data makes it impossible to predict equipment aging or hidden faults.
No Fault Traceability: Without diagnostic records, maintenance crews are forced to perform "blind" troubleshooting on-site.
Cumbersome Operation: Complex interfaces requiring external computers to modify parameters drastically reduce efficiency.
Real-World Case (Urban 10kV Grid) An urban 10kV grid equipped with 20 legacy controllers faced severe O&M challenges. Without monitoring, teams performed labor-intensive manual inspections every three months, costing over 150,000 RMB annually. In 2024, an aging power module caused a controller to "fail to trip," leading to a 4-hour blackout. It then took crews 6 hours of on-site searching just to identify the faulty component.
II. Four Core Solutions: Self-Diagnostics, Early Warning, and Remote Control
Our intelligent O&M system applies to all 10-35kV grid scenarios, focusing on digitization and remote efficiency.
Full-Status Real-Time Monitoring: Integrated sensors for temperature, voltage, and current sync data to a cloud platform, enabling proactive detection of hidden hazards without site visits.
Smart Alerts & Fault Traceability: AI-driven algorithms analyze data to predict failures. If a fault occurs, the system automatically logs the type, time, and location, providing a report that eliminates "blind" searching.
Simplified & Remote Operation: Controllers now feature user-friendly, localized LCD screens. Additionally, a mobile app/cloud platform allows for remote parameter adjustment and switching control, eliminating the need to travel to the site.
Data-Driven Management: The cloud platform generates automated O&M reports, shifting the strategy from "blanket inspections" to targeted, efficiency-based maintenance.
III. Proven Results: Troubleshooting Cut to <30 Minutes, 90,000 RMB Annual Savings
Following the upgrade:
Fault Response: Troubleshooting speed increased by 92%, with average repair times dropping from 6 hours to under 30 minutes.
O&M Costs: Annual expenses were reduced from 150,000 RMB to under 60,000 RMB—a saving of 90,000 RMB.
Operational Efficiency: Overall O&M efficiency rose by 80% due to remote control and data-driven planning.
IV. Triple Protection: Seamless O&M
Technical Support: End-to-end guidance from hardware selection to platform setup, ensuring the system meets real-world needs.
Quality Assurance: Rigorous testing of sensors and cloud platforms, with full-function commissioning before factory departure.
After-Sales Service: 1-year free warranty and lifelong maintenance, including rapid emergency response and O&M personnel training.
