Cách đo nhiệt độ trong môi trường điện áp cao và điện từ cao, and how to use fluorescent optical fibers in electricity-INNO

Temperature measurement can be carried out in high-pressure and high electromagnetic environments using a fluorescent fiber optic temperature measurement system. This system utilizes the temperature dependent properties of fluorescent materials to achieve accurate temperature measurement. Here are some key points of the application of fluorescent optical fibers in power systems:

Principle of Fluorescence Fiber Optic Temperature Measurement
Vật liệu huỳnh quang: The end of the fluorescent fiber is coated with a special fluorescent material that emits fluorescence when illuminated by an excitation light source (usually a laser or LED).
Thời gian phân rã huỳnh quang: The decay time of fluorescence (tức là. the time required for fluorescence to return from the excited state to the ground state) is closely related to temperature. Bằng cách đo thời gian phân rã huỳnh quang, nhiệt độ có thể được tính toán.
Ứng dụng trong hệ thống điện
High voltage equipment monitoring:
Máy biến áp: Fluorescent optical fibers can be installed in key parts inside the transformer, chẳng hạn như cuộn dây và lõi sắt, to monitor temperature in real-time.
Circuit breakers and switchgear: These devices generate heat during operation, and fluorescent optical fibers can help monitor hotspots to prevent malfunctions caused by overheating.
Giám sát cáp:
High voltage cable joints: Cable joints are the most prone to overheating in cable systems, and fluorescent optical fibers can be embedded at the joints to monitor temperature changes in real time.
Hầm cáp: Multiple fluorescent fiber optic sensors can be installed in long-distance cable tunnels to achieve distributed temperature monitoring.
nhà máy điện:
Generator stator and rotor: Temperature monitoring inside the generator is crucial to ensure its normal operation, and fluorescent optical fibers can be embedded inside the generator for real-time monitoring.
Hệ thống làm mát: Monitor the temperature of the cooling system to ensure its effective operation and prevent equipment overheating.
Installation and maintenance
Chống nhiễu điện từ: Fluorescent fiber itself is not sensitive to electromagnetic interference and is suitable for use in high voltage and high electromagnetic environments.
High temperature and high pressure resistance: Choose suitable fluorescent materials and fiber types that can withstand high temperature and high voltage conditions in power equipment.
Hiệu chuẩn thường xuyên: In order to ensure measurement accuracy, it is necessary to regularly calibrate the fluorescence fiber optic temperature measurement system.
Actual case
