Penderia suhu gentian optik INNO ,sistem pemantauan suhu.
Teknologi pemantauan dalam talian pengesan gentian optik mempunyai beberapa kelebihan seperti gangguan anti elektromagnet, jangka hayat yang panjang, saiz kecil, sensitiviti yang tinggi, penukaran fotoelektrik atau elektro-optik yang mudah, dan pemultipleksan.
Bahan pendarfluor yang digunakan dalam gentian optik pendarfluor mengeluarkan isyarat pendarfluor apabila terdedah kepada cahaya pengujaan. Dengan menggunakan ciri-ciri bahan pendarfluor seperti spektrum pengujaan, spektrum pelepasan, dan seumur hidup pendarfluor, pemantauan pelepasan separa dan pemantauan suhu peralatan kuasa boleh dicapai. Dalam pelepasan separa, cahaya malap yang dihasilkan oleh nyahcas separa menyebabkan gentian pendarfluor mengeluarkan isyarat pendarfluor. Dengan menerima isyarat pendarfluor dan melakukan penukaran fotoelektrik, the partial discharge signals can be analyzed and processed.
In temperature monitoring, the most commonly used type is the fluorescence afterglow lifetime temperature sensor. The fluorescence afterglow begins to decay after the light excitation is removed, and the afterglow lifetime depends on the temperature of the object being measured. Temperature is an important operating parameter of power equipment and one of the most direct manifestations of equipment failure. The research hotspot of online monitoring of power systems is to obtain the operating status of power equipment by monitoring its temperature information.
Fiber optic temperature measurement methods are divided into point temperature monitoring and distributed temperature monitoring:
1. Point based temperature monitoring includes fiber optic grating temperature monitoring dan pemantauan suhu gentian optik pendarfluor, mainly used to monitor key abnormal parts in power equipment, including transformer windings, switchgear joints, pemutus litar, dll;
2. Distributed temperature monitoring refers to the use of scattered distributed fiber optic sensors for monitoring, mainly used for comprehensive measurement of transmission line temperature.
gentian pendarfluor optic sensors can also be used to measure the internal temperature of transformers. Fluorescent fiber optic thermometers are used for transformer windings. The probe of the fluorescent material is inserted into the position inside the transformer that needs to be measured, and the temperature is detected by the relationship between the fluorescence lifetime and temperature. Compared with fluorescence intensity type temperature sensors, this method significantly reduces the impact of light source stability.
The point based temperature measurement, including fiber optic grating temperature sensors and penderia suhu gentian optik pendarfluor, is accurate enough to measure to a certain point, suitable for monitoring key parts of power equipment, and is not limited by the power of the light source. It is compact in size and has high sensitivity.
