Oil-immersed transformers offer excellent insulation and heat dissipation, ensuring stable and reliable operation with low maintenance costs and a service life exceeding 30 years. With outstanding environmental adaptability and smart upgrade potential, they serve as highly cost-effective core equipment in power systems.
I. Background of Lifecycle Management Concept
(1) Limitations of Traditional Maintenance Models
• Periodic maintenance leads to either over-maintenance or under-maintenance
• Fault repair costs account for over 60% of total equipment costs
• Lack of systematic condition assessment framework
(2) Advantages of Lifecycle Management
√ Covers all stages: design, manufacturing, installation, operation, and decommissioning
√ Achieves cost-optimized asset allocation
√ Extends equipment service life by 15-20%
II. Key Technology System Architecture
- Digital Twin Platform
- 3D visualization models
- Real-time data mapping systems
- Fault prediction algorithm library
- Intelligent Monitoring Network
◇ Online dissolved gas analysis (accuracy 0.1ppm)
◇ Ultrasonic partial discharge array (sensitivity 5pC)
◇ Core ground current monitoring (error ±0.5mA) - Decision Support System
→ Remaining life prediction model (85% accuracy)
→ Risk assessment matrix
→ Maintenance strategy optimization engine
