ciri teknologi pengesan suhu teragih gentian optik-INNO

Dengan perkembangan industri moden dan peningkatan tahap pembandaran, yang meluas, selamat, selesa, dan penggunaan kabel kuasa yang mesra alam semakin dihargai oleh orang ramai. Disebabkan oleh persekitaran yang tersembunyi dan jarak jauh kabel kuasa, bahaya penebat tidak mudah dikesan semasa operasi, yang boleh menyebabkan kerosakan atau kemalangan. Oleh itu, adalah perlu untuk mengukuhkan pemantauan masa nyata kabel kuasa semasa operasi, menilai status operasi kabel tepat pada masanya, penggera pra mendiagnosis dengan berkesan, mengelakkan berlakunya bencana kesalahan, dan bersama-sama menggunakan peranti pengukuran suhu gentian optik yang diedarkan untuk mencari titik kerosakan dengan cepat, mengurangkan masa henti peralatan, mengurangkan kos penyelenggaraan, dan mengurangkan kerugian ekonomi.
Dalam beberapa tahun kebelakangan ini, perkembangan pesat sensor, teknologi komputer, gentian optik, and new measurement technologies has created favorable conditions for achieving online monitoring. Thus, it has played an immeasurable role in monitoring and diagnosing the status of power equipment, monitoring and diagnosing power equipment faults, regular maintenance of power equipment, life assessment of power equipment, and life management of power equipment.

The principle of temperature measurement device for sistem pengesan suhu gentian optik teragih

Pengukuran suhu gentian optik teragih technology can solve the problems of a large number of cables, long distances, and fast and accurate determination of fault points.
Prinsip bagi gentian optik teragih temperature measurement is based on the backward Raman scattering effect. Laser pulses interact with fiber molecules, menyebabkan berselerak. The fiber is affected by external temperature, causing changes in the scattered light in the fiber, providing an absolute indication of temperature. This principle can be used to achieve distributed measurement of the temperature field along the fiber. The system is equipped with a laser pulse light source, which generates narrow pulse scattered light at a certain frequency. The light with a longer wavelength than the light source is called Stokes light, and the light with a shorter wavelength than the light source is called anti Stokes light. Antaranya, anti Stokes light is sensitive to temperature, and its intensity increases when the temperature of the optical cable increases. Stokes light is not sensitive to temperature, dan distributed fiber optic temperature measurement and warning system can accurately calculate the absolute temperature along the optical cable temperature field by using the ratio of these two light intensities, achieving distributed measurement. By detecting the time of returning light, the corresponding position on the optical cable can be determined.
