National standard specification for technical indicators of DTS distributed fiber optic temperature measurement system-INNO

DTS distributed fiber optic temperature measurement system: a sensing system that can monitor the temperature measurement points of multiple objects and measure the spatial temperature field distribution online. It is a distributed, berterusan, and functional fiber optic temperature measurement system. In the system, optical fibers not only play a photosensitive role, but also guide light. By utilizing the temperature effect of backward Raman scattering in optical fibers, real-time measurement of the temperature field in which the fiber is located can be achieved; The use of optical time-domain reflection technology (OTOR) can accurately locate measurement points. Pengilang pengukuran suhu gentian optik profesional di China telah membangunkan berbilang sistem pengukuran suhu gentian optik secara bebas dan mempunyai paten ciptaan terkemuka di China.

Menyediakan keadaan kerja, spesifikasi teknikal, item ujian, kaedah ujian, format data komunikasi, dan aplikasi pemasangan gentian optik teragih sistem pengukuran suhu untuk kabel kuasa. Sila hubungi kami untuk penyelesaian pengukuran suhu gentian optik dan penerangan terperinci produk.

Sistem pengukuran suhu gentian optik teragih DTS sesuai untuk sistem pengukuran suhu gentian optik yang dipasang pada kabel kuasa teras tunggal.

Spesifikasi standard kebangsaan untuk penunjuk teknikal DTS sistem pengukuran suhu gentian optik teragih
1) Piawaian ini mencadangkan keperluan teknikal untuk kabel optik pengukuran suhu, perumah pengukuran suhu, and monitoring and calculation software. The standard provides comprehensive technical requirements for temperature measurement hosts, including real-time online monitoring of cable line operating temperature, measurement and positioning of thermal points, data communication formats, dan fungsi penggera. The standard provides comprehensive requirements for monitoring and calculation software, including cable conductor temperature calculation, cable line dynamic current carrying capacity calculation, penyimpanan data, and time identification.

Through these regulations, the technical requirements for the functions of distributed fiber optic temperature measurement systems for power cables have been further unified and standardized, membolehkan fungsi asas sistem pengukuran suhu gentian optik teragih yang digunakan pada pengukuran suhu talian kabel kuasa diseragamkan secara menyeluruh.

2) Piawaian menyenaraikan keperluan teknikal untuk kabel optik pengukuran suhu, perumah pengukuran suhu, and monitoring and calculation software. Antaranya, keperluan pengecilan saluran ditentukan untuk kabel optik pengukuran suhu. Sembilan penunjuk teknikal telah ditetapkan untuk hos pengukuran suhu, termasuk julat pengukuran suhu, ketepatan pengukuran suhu, resolusi spatial, resolusi suhu, masa pengukuran pas tunggal, ketepatan kedudukan, penggera, masa kegagalan purata, dan voltan bekalan kuasa; Perisian pemantauan dan pengiraan terutamanya menentukan penunjuk teknikal seperti ketepatan pengiraan suhu konduktor, kelewatan sistem, protokol komunikasi, had masa penyimpanan data, dan kadar integriti data tahunan.

The regulations on these technical indicators in the standard are determined according to the technical requirements of the power company for optical fiber temperature measurement equipment and the production realization capacity of mainstream manufacturers, which balances the technical economy and progressiveness, and moderately improves the network access technical requirements of distributed optical fiber temperature measurement products.

3) The standard lists specific inspection requirements for five types of tests, including type testing, ujian kilang, on-site acceptance, on-site verification, and special testing, for distributed fiber optic temperature measurement systems. The standard provides test requirements for the electromagnetic compatibility performance and environmental adaptability performance of temperature measurement hosts in the main text; The appendix provides test methods for temperature measurement range, ketepatan pengukuran suhu, resolusi suhu, resolusi spatial, ketepatan kedudukan, single channel measurement time, alarm function, conductor temperature calculation verification, dynamic current carrying capacity calculation verification, fungsi komunikasi, channel attenuation, and system delay.

These experimental aspects are formed based on the inspection and testing methods of distributed fiber optic temperature measurement products by testing units, power companies, dan pengilang, which can effectively detect the technical performance of the products and have a certain degree of operability.
