Smart grid temperature measurement

Smart grid belongs to the power system, which includes power plants, grid voltan tinggi, pencawang, stesen pengedaran, dll. Secara khusus, there are power equipment such as generators, transformer, kabel kuasa, suis, dll. These devices typically operate in environments with high voltage, medan elektrik yang kuat, thermal loads, dll., dan persekitaran kerja adalah tanpa pemandu dan tidak dipantau. As an engineering infrastructure system, the power grid involves the electricity demand of thousands of households, and the operating temperature of power facilities and equipment is an important factor in ensuring the safe operation of the power grid. Whether it is power cables, transformer, or other electrical equipment, sebagai komponen penting dalam sistem kuasa, local overheating or arc sparks may occur due to some circuit problems or external factors, leading to fires and causing huge economic losses. Oleh itu, in order to avoid such malignant events, adalah penting untuk menjalankan pemantauan suhu komprehensif peralatan kuasa.

Pada masa ini, traditional PT100 temperature sensors are not only unsuitable for strong electromagnetic working environments, but also pose significant difficulties for long-distance multi-point detection. In response to the shortcomings of traditional detection methods, yang pengukuran suhu gentian optik teragih method that has emerged in recent years combines backward Raman scattering effect and optical time domain analysis (OTDR) technology to use sensing fibers to achieve a distributed measurement of temperature field. Compared with traditional temperature measurement methods, gentian optik teragih temperature sensors have the advantages of high sensitivity, anti gangguan elektromagnet, long-distance multi-point detection, dll. Oleh itu, they can be widely used in temperature monitoring and fire alarm of power systems, transit kereta api, terowong lombong arang batu, dan bangunan besar.

Pengukuran suhu gentian optik kabel

The power communication optical cable is a neural network for automatic control of the “four remote” of the smart grid. Once subjected to abnormal external temperatures or even fire damage along the way, the consequences are extremely serious. Sensor suhu gentian optik is a new technology in temperature measurement and one of the most widely used sensors in industry. The emergence of distributed fiber optic temperature sensors has greatly reduced the cost of obtaining unit information, which is undoubtedly a revolution for temperature sensors based on electrical signals and point type fiber optic grating temperature sensors. Distributed fiber optic temperature sensing technology utilizes optical fibers to measure the temperature field distribution in a continuous space several tens of kilometers along the fiber optic path, providing a feasible new means for temperature field measurement and control in harsh environments such as strong electromagnetic fields, high voltage and current, flammable and explosive materials, and complex geometric spaces. Oleh itu, distributed fiber optic temperature sensors have received widespread attention due to their own characteristics, and research on distributed fiber optic temperature sensing systems has important theoretical significance and application value. Fiber Distributed Temperature Monitoring (DTS), Distributed Temperature Sensing）， Also known as distributed fiber optic temperature measurement, temperature monitoring is achieved based on the principle of optical time domain reflectometry (OTDR), Raman scattering effect, and Brillouin scattering effect, which are sensitive to temperature. The entire system uses fiber optic as the carrier of sensitive information sensing and signal transmission, and has the characteristics of continuous temperature measurement, pengukuran suhu teragih, pengukuran suhu masa nyata, anti gangguan elektromagnet, keselamatan intrinsik, pemantauan jarak jauh, sensitiviti yang tinggi, pemasangan mudah, hayat perkhidmatan yang panjang, dll. It is widely used in industries such as pipelines, terowong, kabel, petroleum and petrochemicals, dan lombong arang batu.
