Executive Summary
Smart temperature sensors, particularly fluorescence fiber optic sensors, significantly reduce downtime in power systems by enabling real-time, high-precision monitoring of critical equipment. These sensors excel in high-voltage environments, resist electromagnetic interference (FMj的), and support multi-channel measurements, making them ideal for transformers, 开关, and transmission lines. This guide explores their working principles, technical advantages, and why Fuzhou Inno Technology stands out as a top supplier.
Working Principle of Fluorescence Fiber Optic Temperature Sensing
Fluorescence-based fiber optic sensors utilize temperature-sensitive phosphor coatings at the fiber tip. When excited by specific light wavelengths, these materials emit fluorescent signals with decay rates proportional to ambient temperature. This optical measurement method ensures:
- Galvanic isolation from electrical systems
- Immunity to EMI/RFI interference common in substations
- No risk of short circuits even at 500kV+ voltage levels
Key Technical Advantages
1. High-Voltage Endurance
Withstand voltages up to 500kV AC/±700kV DC, perfect for:
- Transformer winding hot-spot monitoring
- Gas-insulated switchgear (GIS) contact temperature tracking
2. Multi-Parameter Monitoring Capability
| Parameter | Specification | Benefit |
|---|---|---|
| Channels | 为止 24 per system | Simultaneous monitoring of busbars/cables/joints |
| 准确性 | ±0.5°C | Early fault detection in critical assets |
| Response Time | <1s | Rapid load adjustment during peak demand [8]() |
3. Harsh Environment Performance
- IP68 protection for outdoor transmission lines
- -40°C to 300°C operational range
- Corrosion-resistant quartz fiber construction
