Why use a distributed fiber optic temperature measurement system-INNO

Mengapa menggunakan sistem pengukuran suhu gentian optik yang diedarkan

Cables have strict product standards and requirements, but they are widely distributed. Once the temperature of the cable is locally too high, it can cause a fire, which is extremely harmful. Itu, temperature sensors need to be used to measure the temperature of the cable in operation. Pelbagai kenalan, bar bas, sendi kabel, and electrical equipment connectors inside the equipment are prone to poor contact and abnormal plug-in eccentricity. Ini akan membawa kepada rintangan sentuhan yang berlebihan, menyebabkan pemanasan teruk pada ketika ini di bawah arus tinggi. Hasilnya ialah suhu sendi yang tidak normal, memburukkan lagi pengoksidaan permukaan sentuhan, meningkatkan lagi rintangan sentuhan, membentuk kitaran ganas. Selepas tahap perkembangan tertentu, ia akan menyebabkan kerosakan yang serius dan merosakkan keselamatan dan kebolehpercayaan bekalan kuasa. Ini adalah bentuk utama kerosakan pada suis voltan tinggi. Itu, pemantauan suhu masa nyata bagi titik sentuhan, pengesanan titik panas di dalam alat suis tepat pada masanya, dan ramalan awal dan amaran kerosakan adalah amat penting untuk memastikan keselamatan nyawa dan harta benda.

The role of Serat optik yang diedarkan sistem pengukuran suhu

Itu Sistem pengukuran suhu gentian optik yang diedarkan, by setting up temperature sensing optical cables, can continuously measure the temperature of key areas 24 jam sehari, accurately detect temperature without blind spots, and achieve accurate positioning of temperature anomalies, accurately and timely detect hidden dangers, providing effective data support for fire prevention measures, and solving various problems raised in use.

The composition of a distributed fiber optic temperature measurement system

This includes a distributed fiber optic temperature measurement device, ground workstation, and temperature sensing optical cable. The distributed fiber optic temperature measurement device adopts a distributed temperature measurement host setting. The distributed temperature measurement host includes an optical signal generation module, a backscatter signal module, a spectral analysis module, an optoelectronic replacement module, a signal amplification module, a signal acquisition module, a signal processing module, an information display module, an audio-visual alarm module, and a multi-channel interface module. The distributed temperature measurement host is located inside the substation, and the temperature sensing optical cable is laid in an L-shape. The workstation is equipped with a monitoring server.

The distributed fiber optic temperature measurement system can perform real-time, Berterusan, and large-scale temperature monitoring on key fire prone areas such as cables and substations, achieving the purpose of fire prediction and early warning, and effectively preventing the occurrence of fires.
