Como medir a temperatura em ambiente de alta tensão e alta eletromagnética, 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
Material fluorescente: 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).
Tempo de decaimento da fluorescência: The decay time of fluorescence (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.
Aplicação no sistema de energia
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:
Junções de cabos de alta tensão: 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
Anti interferência 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: Na rede inteligente, 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.
Usinas nucleares: 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, fibras ópticas fluorescentes can effectively measure temperature in high voltage and high electromagnetic environments, providing guarantees for the safe operation of power systems.
