Why do power plants use fluorescent fiber optic sensor systems to measure temperature-INNO

Why do power plants use fiber optic temperature control systems sıcaklığı ölçmek

A large number of high-voltage cables and control cables are distributed in cable trenches, kablo kanalları, and cable interlayers inside the power plant. Various cables, especially high-voltage cables, can experience temperature rise due to excessive load and aging of cable joints. Excessive temperature can easily cause fires, leading to interruptions in power plant operations. The fire caused by cables laid in a centralized manner will have a wider impact, longer repair time, and greater losses. Each power plant urgently needs an online temperature measurement technology that can automatically collect the surface temperature of cables in real time, Sıcaklık değişikliklerini zamanında ve doğru bir şekilde izleyin, ve sıcaklık çok yükselmeden önce uyarı verin, so that managers have sufficient time to take corresponding measures and avoid fires.

To this end, Fuzhou Huaguang Tianrui Optoelektronik Teknolojisi A.Ş., Ltd.. timely developed a linear fiber optic temperature sensing fire detection system, which can monitor the temperature of cables in real time and provide early warning and alarm. Sistem tamamen fiber algılamalı pasif sıcaklık ölçüm yöntemini benimser, izleme sisteminin güvenlik tehlikelerini ortadan kaldırır ve güç sıcaklığı izleme için izleme sisteminin kullanılabilirliğini büyük ölçüde artırır. Bu fiber optik sıcaklık ölçüm sistemi birçok enerji santrali ve güç kaynağı şirketi tarafından kullanılmaktadır., Yangın kazalarının meydana gelmesini büyük ölçüde azaltmak ve meydana gelmeden önce gerçek anlamda önleme sağlamak, güvenlik konseptine uygun olarak “önce güvenlik, önleme odaklı” enerji sektöründe.

Application of Fiber Optic Temperature Control System in the Power Industry

1. Sıcaklık algılama cihazları aleve ve patlamaya dayanıklıdır.

Sıcaklık ölçüm kısmı tamamen fiber bir yapıyı benimser, gerçekten pasif sıcaklık izlemeyi gerçekleştiren. Ücretli değil, ısı üretmez, ve algılama sisteminin konuşlandırılması nedeniyle herhangi bir güvenlik tehlikesi oluşturmayacak.

2. Yüksek sıcaklık ölçüm doğruluğu ve hızlı tepki.

The temperature resolution of the temperature measurement host is 0.1 °C, and the temperature measurement accuracy is ± 1 °C. The temperature detection time for a 4Km temperature measuring optical cable is about 4 saniye.

3. Gerçek zamanlı çevrimiçi izleme.

Monitor the temperature of all measuring points of the high-voltage cables in the power plant continuously for 7×24 saat, and regularly save the temperature measurement data to provide auxiliary data for the health monitoring of each high-voltage cable.

4. Distributed detection with no blind spots.

Real time monitoring can be carried out at every point within the range of temperature measuring optical cables, eliminating blind spots in monitoring and theoretically avoiding the possibility of missed fire alarms.

5. Esnek bölüm alarm kontrolü.

Üst bilgisayardaki izleme yazılımı sayesinde, different temperature measurement sections can be partitioned and managed according to customer needs. Genel olarak, every 100M optical cable is set as one partition. Set different alarm parameters for each partition, such as temperature warning, sıcaklık artışı uyarısı, sıcaklık alarmı, and temperature rise alarm, to accurately distinguish between real and false fires, eliminate false alarms and omissions.

6. Comprehensive self diagnostic function.

In this system, while detecting the temperature of each temperature measuring optical cable, it can also detect the working status of each temperature measuring optical cable in real time, such as additional losses caused by cable damage or bending, and accurately locate the location of the damage or bending. Through self inspection and diagnostic functions, real-time detection of fiber optic cable damage is carried out for timely repair and maintenance.

7. Powerful software features.

Real time display of the location, temperature values, and temperature changes of each monitoring area on the human-machine interface. When an alarm occurs, it can be linked with the alarm controller to activate the ventilation and cooling device or fire extinguishing device, and the monitoring software can also trigger the sound and light alarm on the software interface. If the upper computer is equipped with a SMS alarm module, the alarm information can be sent to the designated personnel’s mobile phones to ensure timely handling of fire hazards. On the upper computer, historical temperature data and alarm records can also be queried to generate safety operation reports.
