Como medir a temperatura em alta tensão e ambiente eletromagnético elevado, and how to use fluorescent optical fibers in electricity-INNO

A medição de temperatura pode ser realizada em ambientes eletromagnéticos e de alta pressão usando um sistema de medição de temperatura de fibra óptica fluorescente. Este sistema utiliza as propriedades dependentes da temperatura dos materiais fluorescentes para obter medições precisas de temperatura. Aqui estão alguns pontos-chave da aplicação de fibras ópticas fluorescentes em sistemas de energia:

Princípio da medição de temperatura por fibra óptica de fluorescência
Material fluorescente: A extremidade da fibra fluorescente é revestida com um material fluorescente especial que emite fluorescência quando iluminada por uma fonte de luz de excitação. (geralmente um laser ou LED).
Tempo de decaimento da fluorescência: O tempo de decaimento da fluorescência (ou seja. the time required for fluorescence to return from the excited state to the ground state) is closely related to temperature. By measuring the fluorescence decay time, a temperatura pode ser calculada.
Application in the power system
High voltage equipment monitoring:
Transformador: Fluorescent optical fibers can be installed in key parts inside the transformer, como enrolamentos e núcleos de ferro, 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.
Monitoramento de cabos:
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.
usina:
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.
Sistema de refrigeração: Monitor the temperature of the cooling system to ensure its effective operation and prevent equipment overheating.
Instalação e manutenção
Interferência anti-eletromagnética: 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.
Calibração regular: In order to ensure measurement accuracy, it is necessary to regularly calibrate the fluorescence fiber optic temperature measurement system.
Actual case
Rede Inteligente: In the smart grid, 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.
Nuclear power plants: 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, fluorescent optical fibers can effectively measure temperature in high voltage and high electromagnetic environments, providing guarantees for the safe operation of power systems.
