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
Fluorescent material: 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).
Fluorescence decay time: The decay time of fluorescence (अर्थात्. 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, the temperature can be calculated.
Application in the power system
High voltage equipment monitoring:
Transformer: Fluorescent optical fibers can be installed in key parts inside the transformer, such as windings and iron cores, 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.
Cable monitoring:
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.
Cooling system: Monitor the temperature of the cooling system to ensure its effective operation and prevent equipment overheating.
Installation and maintenance
विरोधी विद्युत चुम्बकीय हस्तक्षेप: 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.
Regular calibration: In order to ensure measurement accuracy, it is necessary to regularly calibrate the fluorescence fiber optic temperature measurement system.
Actual case
Smart Grid: 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.
