回転機械用蛍光光ファイバー温度監視システム

A large-scale power generation facility required precise temperature monitoring for their 発電機の固定子巻線. Traditional PT100 sensors faced significant challenges in high-voltage rotating machine environments due to electromagnetic interference and electrical insulation requirements. The customer needed a reliable solution for 多点温度測定 that could withstand harsh electromagnetic conditions while providing accurate real-time data.

解決: 蛍光ファイバーによる温度監視

We implemented a comprehensive 光ファイバー温度監視システム specifically designed for rotating electrical machines. The installation features:

システム構成

Multiple Fluorescent Fiber Optic Sensors: Strategically positioned around the stator core circumference
Direct Winding Contact: Sensors placed directly on stator winding slots for accurate hot spot detection
Specialized Mounting System: Blue fixing clamps ensure stable sensor positioning during operation
Multi-Channel Monitoring: Simultaneous temperature tracking across all critical measurement points

Why Fiber Optic for Rotating Machines?

Superior Performance in High-Voltage Environments

完全な電気絶縁: Fiber optic sensors are non-conductive, eliminating electrical breakdown risks in generator high-voltage environments. This is critical for stator winding temperature monitoring where voltages can exceed 10kV.

EMI耐性: Unlike PT100 RTD sensors, fluorescent fiber optic technology is completely immune to electromagnetic interference generated by rotating magnetic fields in generators and motors.

高精度: Fluorescence lifetime-based temperature measurement achieves ±0.5℃ accuracy, enabling precise 熱管理 and early fault detection.

本質安全防爆: No electrical components at sensing points means zero spark risk, meeting strict safety requirements for power generation equipment.
