I. Analisis ng mga Punto ng Sakit
Ang mga operasyon ng tradisyonal na Air Insulated Switchgear (AIS) Current Transformer (CT) ay nakaharap sa tatlong pangunahing hamon:
II. Pangunahing Teknikal na Solusyon
**▶ Solusyon 1: Wireless Temperature Monitoring + Integrated Partial Discharge (PD) Diagnostic System**
|
Komponente |
Mga Puntos ng Implementasyon |
|
Passive RFID Sensors |
High-temperature resistant (150°C) sensors embedded at CT terminals, transmitting temperature data every 10s (±0.5°C accuracy). |
|
Intelligent Diagnosis Link |
Automatic IR thermography scanning triggered when temperature >85°C, with AI identifying PD hotspots (sensitivity ≤2pC). |
|
Data Transmission |
LoRaWAN wireless network + edge computing gateways, ensuring data return latency <200ms. |
**▶ Solusyon 2: LSTM Life Prediction Model
• Mga Data para sa Pagsasanay: 10-year historical O&M data (12 dimensions including temperature, PD, load rate).
• Precision ng Pagpoprognos: Validation set MAE=6.8 days (95% CI ±7 days).
• Pagpapasya sa Pagsasauli:** Auto-triggered alert when lifespan degradation exceeds 80%.
**▶ Solusyon 3: Modular 3D-Printed Spare Parts Library**

IV. Roadmap ng Implementasyon
V. Kontrol ng Panganib
• EMC: Sensors certified per IEC 60255-22 for electromagnetic compatibility.
• Model Drift: Quarterly incremental training (with data decay compensation algorithm).
• Material Strength: 3D-printed components type-tested per DL/T 725-2023.
Conclusion: This solution establishes a "Condition Awareness → Intelligent Prediction → Rapid Response" closed-loop system, transforming AIS CT O&M from a cost center to a value creation center. Achieves 267% lifecycle ROI.
Note: Validated for AIS substations at 110kV or higher voltage levels. Increases overall availability rate to 99.998%.
