Fluorescent fiber optic temperature sensing probes have many advantages that other temperature sensing probes cannot compare to, such as good electrical insulation, Beständigkeit gegen elektromagnetische Störungen, chemical corrosion, and no pollution. This makes fluorescent sensing probes not only used in many fields such as biology and medicine, but also have broad application prospects in the power industry. They are mainly used for temperature measurement of high-voltage instruments in electrical equipment, temperature measurement between generator diagnostic systems and transformer windings, temperature measurement of high-voltage circuit breaker contacts, and temperature measurement of high-voltage cable joints.
Introduction to Fluorescent Fiber Optic Sensing Probes
The fiber optic probe consists of three parts: ST connector, fiber optic cable, and end temperature sensing end. The ST connector is the connection part with the photoelectric module; Fiber optic cable is the transmission part, with quartz fiber inside. The quartz fiber has a coating and cladding on the outside, and a Teflon protective sleeve on the outermost part; The end temperature sensing end contains temperature sensing rare earth materials, which are used to generate optical signals containing temperature information; The optical fiber is resistant to high temperatures of 200 ℃ and has an outer diameter of 3mm. Long term bending radius of 13.2cm. Short term bending radius of 4.4cm. When the distance between the fiber optic lead and the ground is 0.4m, it can withstand a power frequency voltage of 100KV for a duration of 5 minutes.
The Temperature Measurement Principle of Fluorescent Fiber Optic Temperature Sensor
Ein faseroptischer Fluoreszenz-Temperatursensor besteht aus einer Multimode-Faseroptik und einem fluoreszierenden Objekt (Membran) oben installiert. Fluoreszierende Substanzen geben Fluoreszenzenergie ab, wenn sie durch Licht einer bestimmten Wellenlänge stimuliert werden (stimuliertes Spektrum). Nachdem der Anreiz widerrufen wurde, Die Persistenz des Fluoreszenz-Nachleuchtens hängt von Faktoren wie den Eigenschaften der fluoreszierenden Substanz und der Umgebungstemperatur ab. Diese angeregte Fluoreszenz zerfällt in der Regel exponentiell, und die Abklingzeitkonstante wird als Fluoreszenzlebensdauer oder Fluoreszenznachleuchtzeit bezeichnet. Die Dämpfung des Fluoreszenz-Nachleuchtens variiert bei unterschiedlichen Umgebungstemperaturen. Deshalb, durch Messung der Lebensdauer des Fluoreszenz-Nachleuchtens, Die Umgebungstemperatur zu diesem Zeitpunkt kann bestimmt werden.
