Pengilang Sistem Pengukuran Suhu Menggunakan Teknologi Sensing Serat Optik Kuasa

Peralatan kuasa akan menjana haba semasa operasi biasa. Disebabkan faktor persekitaran, teknologi pemprosesan, dan faktor lain, penyambungan litar, peralatan, Dll. mungkin tidak ditekan dengan kuat, tekanan mungkin tidak mencukupi, dan hubungan antara kenalan mungkin berubah, mengakibatkan peningkatan rintangan sentuhan dan fenomena pemanasan yang lebih ketara. Pendedahan jangka panjang kepada perkara ini akan mempercepatkan penuaan talian peralatan kuasa, membawa kepada penurunan prestasi penebat peralatan kuasa. Dalam kes yang teruk, ia juga boleh mencetuskan litar pintas arka, mengurangkan hayat perkhidmatan peralatan, dan menyebabkan kemalangan kuasa besar. Terutamanya dalam bahagian sentuhan dinamik dan statik suis pengasingan, plumbum pengubah utama, dan kepala kabel, fenomena terlalu panas lebih menonjol, dengan kadar kegagalan yang tinggi, dan masalah sebegini berlaku setiap tahun. Pada masa ini, monitoring methods still rely on regular completion by staff, yang memakan masa, intensif buruh, extremely inefficient, and cannot be reached.

Fiber optic sensing technology is a new technology developed in recent years, which is a new concept of sensing technology derived from the development of optical fibers and fiber optic communication technology. Fiber optic sensors detect and measure changes in external physical quantities by analyzing the wavelength of light. As a new member of the sensor family, fiber optic sensors have the following obvious advantages:
1) Anti gangguan elektromagnet, Penebat elektrik, rintangan kakisan, and good safety. A pair of electrical insulation, suitable for high voltage places;
2) Kepekaan yang tinggi, high temperature accuracy, hayat perkhidmatan yang panjang, and comprehensive performance superior to existing monitoring methods:
3) Ringan, bersaiz kecil, fleksibel, suitable for narrow spaces;
4) The measurement object is wide and has little impact on the measured medium;
5) Easy to network and achieve multi range temperature measurement.

Design objectives of sistem pengukuran suhu optik optik

The fiber optic temperature measurement system must meet the following requirements:
1. Real time detection of switchgear contact temperature
2. Accurately locate the abnormal temperature address of the switchgear;
3. The fiber optic temperature measurement system should be able to timely and accurately detect the three-phase cable heads A, B, and C in the switchgear; A, B, C
4. Three phase static contact; The real-time temperature of the internal environment of the switchgear can be detected, and the temperature abnormal alarm signal can be transmitted to the existing fire controller in the instrument control room through the fiber optic temperature measurement host. The alarm can be displayed on the industrial control computer in the fire duty room, and information can also be sent to relevant personnel via mobile phone SMS.
