Why do power plants use fiber optic temperature control systems to measure temperature
A large number of high-voltage cables and control cables are distributed in cable trenches, cable trays, 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. O le vevela tele e faigofie lava ona mafua ai le afi, 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, mataituina suiga o le vevela i se taimi talafeagai ma le sao, ma tuuina atu lapataiga a o lei maualuga tele le vevela, so that managers have sufficient time to take corresponding measures and avoid fires.
To this end, Fuzhou Huaguang Tianrui Optoelectronic Technology Co., 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. E faaaoga e le polokalama se auala e fuaina ai le vevela o le tino, aveesea o tulaga lamatia o le saogalemu o le polokalama o le mataituina lava ia ma faaleleia tele ai le mauaina o le polokalama mataituina mo le mataituina o le vevela o le malosiaga. O lenei faiga o le fuaina o le vevela o le vaai mamao e faaaoga e le tele o falegaosi eletise ma kamupani e sapalai ai le eletise, faaitiitia tele le tupu o faalavelave tau afi ma ausia moni ai le puipuiga a o lei tupu, e ogatasi ma le manatu faavae o le saogalemu o le “saogalemu muamua, e faasino i le puipuiga” i le faiga o le malosiaga.
Application of Fiber Optic Temperature Control System in the Power Industry
1. O masini e lagona ai le vevela e tetee atu i le afi ma e le mafai ona pa.
O le vaega e fuaina ai le vevela e faaaoga ai se fausaga o le vaega o le vevela, lea e iloa moni ai le mataituina o le vevela. E le o totogia, e le faatupuina ai le vevela, ma o le a le tulai mai ai ni tulaga lamatia mo le saogalemu ona o le faaaogaina o le polokalama o le lagonaina.
2. Maualuga le fuaina o le vevela ma le tali vave.
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 sekone.
3. Mataituina o le taimi moni i luga o le initoneti.
Monitor the temperature of all measuring points of the high-voltage cables in the power plant continuously for 7×24 itula, 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. Puleaina o le faailo o vaevaega fetuutuunai.
E ala i le polokalama o le mataituina i le komepiuta pito i luga, different temperature measurement sections can be partitioned and managed according to customer needs. E masani lava, every 100M optical cable is set as one partition. Set different alarm parameters for each partition, e pei o le lapataiga i le vevela, lapataiga o le vevela, faailo vevela, ma le faailo o le vevela, ia iloa lelei le eseesega i le va o afi moni ma afi sese, aveesea o faailo ma mea sese e le o i ai.
6. Faatinoga atoatoa o le suesueina o le tagata lava ia.
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. Vaega malolosi o polokalama.
Faaali atu le taimi moni o le nofoaga, tulaga faatauaina o le vevela, ma suiga o le vevela o eria taitasi e mataituina ai i luga o le faafesootaiga o le tagata ma le masini. 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. Afai ua faaauupegaina le komepiuta pito i luga i se faailo SMS, e mafai ona auina atu faamatalaga o le faailo i telefoni feaveai a le aufaigaluega ua atofaina ina ia mautinoa ai le taulimaina i le taimi sao o tulaga lamatia o le afi. I le komepiuta pito i luga, o faamatalaga o le vevela o talafaasolopito ma faamaumauga o faailo e mafai foi ona fesiligia e faatupuina ai lipoti o le faagaoioiga o le saogalemu.
