Sensori i temperaturës me fibër optike, Sistemi inteligjent i monitorimit, Prodhues i shpërndarë i fibrave optike në Kinë

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 (EMI), and support multi-channel measurements, making them ideal for transformers, komutues, 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	Up to 24 per system	Simultaneous monitoring of busbars/cables/joints
Accuracy	±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
