What does armored single-mode temperature measuring optical fiber mean
To enhance the performance of optical fibers, a protective “armor” is added between the coating layer and the core cladding layer to form armored optical fibers. While not affecting the various superior optical properties of the fiber itself, the tensile and compressive strength of the fiber is enhanced, solving problems such as impact resistance, lateral pressure resistance, and rat bite resistance. People have started to coat the fiber bundle with another layer. Fiber optic distributed temperature measurement is widely used in temperature monitoring and fire alarm of facilities such as power, पेट्रोकेमिकल्स, वाहतूक, buildings, and water conservancy. The length of high-voltage transmission cables is very long, and any point on the cable that overheats may cause huge economic losses.
The composition of a distributed fiber optic temperature measurement system
The distributed fiber optic temperature measurement system adopts armored fiber optic to prevent various external forces from damaging. The main temperature measurement components include temperature measurement host, स्विच, सर्व्हर, temperature measurement optical cable, and fire controller. The temperature measurement host, स्विच, and server are connected through a communication backbone network. The fire controller is equipped with a relay unit, and the fire controller is connected to the temperature measurement host. The temperature measurement optical cable is connected to the temperature measurement host.
Distributed fiber optic temperature measurement system for mining
Various contacts, बसबार, cable joints, and electrical equipment connectors inside mining equipment are prone to poor contact and abnormal plug-in eccentricity. This will lead to excessive contact resistance, causing severe heating at this point under high current. The result is abnormal joint temperature, exacerbating contact surface oxidation, further increasing contact resistance, forming a vicious cycle. After a certain stage of development, it will cause serious faults and damage the safety and reliability of power supply. This is the main form of fault in high-voltage switchgear. त्यामुळे, real-time temperature monitoring of the contact points, timely detection of hot spots inside the switchgear, and early prediction and alarm of faults are extremely important for ensuring the safety of life and property.
The principle of distributed fiber optic temperature measurement system
One of the temperature measurement techniques, which is based on Raman scattering and optical time-domain reflection technology, can achieve the measurement of temperature and distance. Specifically, Raman reflection is based on the temperature effect of backward Raman scattering spectra generated during the propagation of light in optical fibers. जेव्हा घटना प्रकाश क्वांटम फायबरमधील भौतिक रेणूंशी टक्कर घेते, लवचिक आणि लवचिक टक्कर होतात. जेव्हा लवचिक टक्कर होते, प्रकाश क्वांटम आणि भौतिक रेणूंमध्ये ऊर्जा विनिमय होत नाही, आणि प्रकाश क्वांटमची वारंवारता कोणत्याही प्रकारे बदलत नाही, परिणामी रेले विखुरणारा प्रकाश घटना प्रकाशासारखीच तरंगलांबी राखतो; लवचिक टक्कर मध्ये, ऊर्जा विनिमय होतो, and photons can release or absorb phonons, resulting in the production of a longer wavelength Stokes silk light and a shorter wavelength Stokes light. Anti Stokes ला तापमानाला अतिसंवदेनशीलता असल्याने, सिस्टीम संदर्भ चॅनेल म्हणून स्टोक्स ऑप्टिकल चॅनेल आणि सिग्नल चॅनेल म्हणून अँटी स्टोक्स ऑप्टिकल चॅनेल वापरते. The ratio of the two can eliminate non temperature factors such as light source signal shifting and fiber bending, तापमान माहिती गोळा करणे. The principle of fiber optic temperature measurement is based on the backward Raman scattering effect.
