Applications in Transformers and Switchgear
1. Transformatorüberwachung
1.1 Winding Hotspot Detection
Optical fiber sensors are embedded directly into transformer windings to monitor hotspot temperatures, providing early warnings of insulation degradation and preventing catastrophic failures. Fluorescence-based sensors offer millisecond response times and ±0.5°C accuracy, critical for detecting subtle temperature increases.
1.2 Überwachung der Öltemperatur
Sensors placed in transformer oil tanks measure bulk oil temperature and detect thermal stratification, ensuring efficient cooling system operation and extending transformer lifespan.
1.3 Buchsenüberwachung
By monitoring bushing temperatures, optical fiber systems identify potential faults such as loose connections or insulation breakdowns before they escalate into major issues.
2. Überwachung von Schaltanlagen
2.1 Kontakttemperaturüberwachung
Fiber sensors are installed on switchgear contacts (both fixed and moving) to detect overheating caused by poor connections or arcing. This is particularly critical in high-voltage environments where traditional sensors cannot operate safely.
2.2 Cable Joint Monitoring
At cable terminations and joints, where faults frequently occur, optical fiber systems provide continuous temperature monitoring, enabling predictive maintenance and reducing unplanned outages.
2.3 Arc Fault Detection
Rapid temperature rises detected by fiber sensors can trigger immediate shutdowns, protecting personnel and equipment from arc flash hazards.
3. Advantages in Power Equipment
- Elektrische Isolierung: Eliminates risks of short circuits in high-voltage environments.
- Langzeitstabilität: Resistant to electromagnetic interference and chemical corrosion, ensuring reliable operation over decades.
- Echtzeitüberwachung: Enables predictive maintenance strategies, reducing downtime and repair costs.
- Kompaktes Design: Sensors as small as 0.25mm diameter fit into tight spaces within equipment.
