  • Description

  • The fluorescent optical fiber temperature sensing technology used in this system has the advantages of anti-high voltage, no electromagnetic interference, long-term reliability, easy expansion, etc. It can monitor the temperature of box transformer, high-voltage switchgear, ring network cabinet, outdoor and underground cable joints of power generation and power supply system in real time.


    Introduction to the principle of fluorescence optical fiber temperature measurement
    The fluorescent optical fiber temperature sensor technology has made a major breakthrough in the anti-electromagnetic interference, insulation, reliability and stability, corrosion resistance, accuracy, life, size and other aspects of the temperature sensor. The technical problems of temperature monitoring and monitoring that have plagued related industries for a long time in special industrial environments such as high voltage, electromagnetic interference and chemical corrosion are solved. The process control, safety monitoring, improvement of energy efficiency and production efficiency of equipment use in the above-mentioned special industrial environment provide advanced concepts and technical means.
        
    Fluorescence temperature measurement: some substances absorb and store energy from the outside world and enter the excited state. When it returns to the ground state from the excited state, the excess energy is emitted in the form of electromagnetic radiation, which is called fluorescence. A substance having such characteristics becomes a fluorescent substance. The fluorescent temperature sensing probe is composed of a multimode fiber and a fluorescent substance mounted on top of it. After the fluorescent substance is excited by light of a certain wavelength (excited spectrum), the excited substance emits fluorescent energy. The persistence of the fluorescence emission after the excitation disappears depends on the properties of the fluorescent substance, environmental factors, and the lifetime of the excited state. This excited fluorescence usually decays exponentially, and the time constant of decay is called the fluorescence lifetime or fluorescence fading time. At different ambient temperatures, the fluorescence lifetime is not the same, so by measuring the length of the fluorescence lifetime, you can know the ambient temperature at that time.
