Principle of Fluorescent Fiber Temperature Measurement

The fluorescence temperature measurement system is coated with fluorescent material at the end of the optical fiber. After being excited by a certain wavelength of light, the fluorescent material is stimulated to emit fluorescence energy. Due to the exponential decay of stimulated radiation energy, the time constant of decay varies depending on temperature. By measuring the decay time, the temperature of the measurement point can be obtained. This method is for fiber optic single point temperature measurement. By utilizing the principle that the afterglow time of rare earth special fluorescent substances is related to temperature, temperature information can be obtained through afterglow time. This technology has been verified to be applicable for monitoring the winding temperature of ultra-high voltage (750KV) transformers. The sensor has a small size, high long-term reliability, moderate price, and can not only achieve single-sided cabinet configuration, but also build a temperature monitoring system. The construction and debugging process is convenient and fast.
The fluorescence fiber optic temperature measurement system has achieved real-time temperature measurement at the contacts, incoming and outgoing lines, busbars, and other positions of high-voltage switchgear. It is more convenient than gallium arsenide semiconductor fiber optic temperature measurement, with high cost-effectiveness, more accurate temperature measurement, no need for regular maintenance, small demodulator volume, and easy installation.
