Technical Field

[0001] The utility model relates to the technical field of temperature measuring equipment, in particular to an optical fiber temperature sensing device. Background Art

[0002] The fiber optic temperature sensing device specifically uses a fiber optic temperature sensor in conjunction with a temperature measuring device in a control box. It uses the principle that the spectrum absorbed by some substances changes with temperature to analyze the spectrum transmitted by the fiber optic to understand the real-time temperature. The main materials are optical fiber, spectrum analyzer, transparent crystal, etc. It is divided into distributed and fiber optic fluorescence temperature sensors.

[0003] In the patent with publication number CN203824669U, a fiber optic temperature sensing device is proposed. In this patent, the fiber optic sensor head is placed on the high-voltage switch or high-voltage busbar to sense the temperature signal, and the signal is transmitted back to the circuit through the temperature-sensitive optical fiber. The circuit is placed away from the high-voltage part. In this way, the high-voltage part only has the temperature-sensitive optical fiber and does not need power supply. The problems of electronic components on the high-voltage side, power supply on the high-voltage side, electromagnetic interference and thermal stability of the high voltage are solved. The device has a simple structure and low cost, and is suitable for mass production and application. However, the following problems still exist in this patent:

However, some placement surfaces are relatively smooth. When the fiber optic temperature sensor is placed on a smooth surface, it is easy for the fiber optic temperature sensor to slip or even fall when pulled by the optical fiber pipeline. In fact, the plane placement stability of the fiber optic temperature sensor is poor, and the use effect is not good.

[0005] In view of the above problems, it is necessary to design an optical fiber temperature sensing device to overcome the above problems. Utility Model Content
