Як виміряти температуру в середовищі високої напруги та сильного електромагнітного випромінювання, і як використовувати флуоресцентні оптичні волокна в електриці

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
Флуоресцентний матеріал: 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).
Час згасання флуоресценції: The decay time of fluorescence (тобто. the time required for fluorescence to return from the excited state to the ground state) is closely related to temperature. Вимірюючи час згасання флуоресценції, температуру можна розрахувати.
Застосування в енергосистемі
High voltage equipment monitoring:
Трансформатор: Fluorescent optical fibers can be installed in key parts inside the transformer, такі як обмотки та залізні сердечники, 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.
Моніторинг кабелю:
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.
Cable tunnel: Multiple fluorescent fiber optic sensors can be installed in long-distance cable tunnels to achieve distributed temperature monitoring.
power plant:
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.
Система охолодження: Monitor the temperature of the cooling system to ensure its effective operation and prevent equipment overheating.
Installation and maintenance
Анти електромагнітні перешкоди: 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.
Регулярне калібрування: In order to ensure measurement accuracy, it is necessary to regularly calibrate the fluorescence fiber optic temperature measurement system.
Actual case
Smart Grid: У розумній мережі, fluorescent fiber optic temperature measurement systems are widely used for temperature monitoring of various high-voltage equipment, improving the safety and reliability of the power grid.
Атомні електростанції: In nuclear power plants, fluorescent optical fibers are used to monitor the temperature of reactors and related equipment to ensure their safe operation.
Through the above methods, флуоресцентні оптичні волокна can effectively measure temperature in high voltage and high electromagnetic environments, providing guarantees for the safe operation of power systems.
