distributed temperature sensing fiber optic cable monitor

Pembinaan bandar moden telah mengemukakan keperluan yang lebih tinggi untuk penghantaran kuasa kami. Dengan perkembangan berterusan industri kuasa, talian penghantaran atas bandar digantikan dengan kabel voltan tinggi bawah tanah. Walau bagaimanapun, Oleh kerana persekitaran yang kompleks di mana kabel bawah tanah terletak, Prestasi penebat kabel bawah tanah menjadi isu utama dalam menentukan kebolehpercayaan penghantaran kuasa. Penuaan dan kerosakan penebat kabel berkait rapat dengan suhu teras operasi jangka panjang. Apabila talian kabel dikebumikan di bawah tanah, amat penting untuk memantau suhu operasi talian kabel, grasp their operating conditions, and provide a basis for future cable line selection and design current carrying capacity calculation. Sebagai fenomena yang muncul dalam talian penghantaran, Terowong kabel kuasa memainkan peranan penting dalam operasi grid kuasa. Memastikan operasi terowong kabel kuasa yang selamat adalah sangat penting.
To measure and analyze the temperature of the two cable lines in operation, in order to determine the impact of different laying environments on the cable current carrying capacity under a certain current carrying capacity, in order to fully utilize the cable conveying capacity and ensure cable safety. The temperature measurement fiber is laid on the surface of the above-mentioned cable.

Itu Sistem pengukuran suhu gentian optik yang diedarkan monitors the surface temperature of the cable and determines its operation by converting the core temperature of the cable. It evaluates the system and calculates the current carrying capacity of the system at any time, ensuring the safe and economical operation of the cable system. Dengan memantau suhu kabel, Suhu operasi kabel boleh dikawal pada bila-bila masa, yang bukan sahaja boleh mengelakkan operasi jangka panjang kabel di bawah beban berlebihan, tetapi juga menyesuaikan beban kabel tepat pada masanya mengikut suhu operasi, yang sangat bermanfaat untuk operasi sistem kuasa yang selamat dan menjimatkan. Sementara itu, Dengan membandingkan kesan kaedah peletakan kabel yang berbeza pada kapasiti tampung semasa, asas disediakan untuk pemilihan kaedah peletakan kabel pada masa akan datang.

Compared with traditional sensors, distributed fiber optic temperature measurement systems have many natural advantages, mainly including:

1) Continuous distributed measurement
Gentian optik teragih sensors are truly distributed measurements that can continuously obtain measurement information along the detection fiber optic for tens of kilometers, greatly reducing false alarm and false alarm rates, and achieving real-time monitoring.

2) Anti gangguan elektromagnet, achieving on-site no electricity detection.
The optical fiber itself is composed of quartz material, which is completely electrically insulating; Pada masa yang sama, the signal of fiber optic sensors is carried by optical signals, which are inherently safe and not affected by any external electromagnetic environment interference. The tank area can enter without electrification, thus eliminating the potential danger of electric sparks in areas containing combustible mixed gases, and achieving on-site zero electricity detection, which is inherently safe.

3) Intrinsic lightning protection.
Thunder often damages a large number of electrical sensors. Penderia gentian optik, due to their complete electrical insulation, can withstand the impact of high voltage and high current.

4) Long measurement distance, suitable for remote monitoring.
The two outstanding advantages of optical fiber are large data transmission volume and low loss. It can achieve remote monitoring for tens of kilometers without the need for relays.

5) High sensitivity and measurement accuracy.
In theory, the sensitivity and measurement accuracy of most fiber optic sensors are superior to general sensors, and this has been proven by mature products in practice.

6) Jangka hayat yang panjang, Kos rendah, and simple system.
The material of optical fibers is generally quartz glass, which has the characteristics of non corrosion, fire resistance, water resistance, and long service life, and can usually serve for 30 Tahun.

Taking into account the cost of the sensor itself and future maintenance costs, the use of fiber optic sensors can greatly reduce the operating costs of the entire project,
