1. Gambaran Keseluruhan Projek
1.1 Latar Belakang Aplikasi
Kepintaran dan penyeragaman pemantauan suhu dalam sistem bekalan kuasa busbar adalah asas untuk status penghantaran kuasa masa nyata, keadaan suhu, dan juga pengesanan rondaan.
Dalam aplikasi praktikal busbar, disebabkan oleh operasi jangka panjang di udara dan pengaruh suhu dan kelembapan sekeliling, pengembangan dan pengecutan haba, penskalaan permukaan, pengoksidaan atau kakisan mungkin berlaku, mengakibatkan sentuhan longgar dan sentuhan lemah, terutamanya di beberapa bangunan besar (seperti kilang besar, bangunan super tinggi, dll.) where the installation position of busbars cannot be monitored manually. Users often neglect the safety management of busbars. Once the temperature of the busbar joints during operation is abnormally high, it may lead to fires or major safety and quality accidents, causing huge and irreparable personal injury and economic property losses to enterprises.
The bus duct is in a fully enclosed state during operation and is generally in a long-term live state, making daily maintenance and inspection very inconvenient. Oleh itu, it is necessary to monitor the temperature of the bus duct to improve its reliability.
Penderiaan Suhu Teragih (DTS) is currently the most advanced temperature measurement technology internationally. Penderiaan suhu gentian optik teragih DTS adalah berbeza sama sekali daripada sistem pengesan suhu tradisional berdasarkan isyarat elektrik. Sama ada kesukaran teknologi pengukuran, kandungan dan penunjuk pengukuran suhu, atau peristiwa dan skop pengukuran, ia telah dinaikkan ke peringkat baharu. Yang diedarkan sensor suhu gentian optik sistem boleh mengukur dan memaparkan nilai suhu pelbagai titik pada keseluruhan kabel gentian optik berterusan dalam bentuk fungsi jarak yang berterusan. Teknologi ini hanya memerlukan satu gentian optik untuk mengukur suhu pada jarak sepuluh kilometer. Pengalaman aplikasi kejuruteraan domestik dan antarabangsa telah menunjukkan bahawa sistem pengesan suhu gentian optik teragih adalah peranti pemantauan yang sangat berkesan untuk pemantauan suhu dalam sistem kuasa.

A large number of practical applications and tests have proven that distributed fiber optic temperature sensing technology has excellent stability and reliability. Selain itu, optical fibers have the characteristics of corrosion resistance, rintangan suhu tinggi, no static electricity, and no radiation. This enables the system to provide stable, boleh dipercayai, and economical solutions for various industrial needs based on temperature detection.
Secara ringkasnya, fiber optic temperature sensing technology is currently the most advanced temperature sensing technology internationally, with inherent explosion-proof, rintangan gangguan elektromagnet yang kuat, penebat elektrik yang baik, perlindungan kilat, ketepatan tinggi, ringan, dan saiz kecil. It can simultaneously measure the temperature distribution on the entire fiber optic cable, surpassing all traditional quasi distributed temperature measurement or alarm systems. It is also a highly intelligent and automated monitoring technology, which does not require manual inspection of the monitored area. The monitoring room screen can display temperature information of each point in the entire monitoring area; When there is an overheating point, it can sound or light an alarm, or send it to relevant personnel via SMS. It can effectively solve the problem of temperature monitoring in complex environments that traditional temperature measurement techniques could not solve before. It can accurately predict hot spots before accidents occur, with a positioning accuracy of 1 meter, and display the evolution of hot spot temperature, truly achieving preventive measures. Oleh itu, distributed fiber optic temperature sensors have received widespread attention worldwide and have begun to be widely applied.

1.2 Kepentingan Pemantauan Suhu Busbar
Monitoring the temperature of the busbar has the following significance:
Safely increase the current carrying capacity of the circuit;
Can achieve periodic state monitoring;
Drive external alarm or other emergency systems;
Discovering hotspots (especially bus joints with potential accident hazards) and other environmental anomalies.

1.2.1 Menyediakan sokongan teknikal untuk keselamatan peralatan busbar
With the national standardization requirements for high-risk environments and the development of intrinsic safety optical communication technology, some technologies in optical communication have gradually provided a technical platform for the application of sensing fields, and distributed fiber optic sensors are one of them. It can scientifically and inherently safely complete the monitoring work of the busbar, and is the best choice for busbar temperature monitoring.
Real time online monitoring of bus temperature can be achieved. It can provide sound and light warnings, penggera, dll. for safety signals such as high and low temperatures and abnormal conditions.
1.2.2 Intrinsic safety of the equipment itself
This product adopts distributed fiber optic detection technology to achieve temperature measurement without electricity, which is truly inherently safe. Strong anti electromagnetic induction and anti-interference ability, very suitable for temperature monitoring applications in the coal mining industry, with great technical and safety advantages.
1.2.3 Application purpose
Distributed fiber optic temperature monitoring system is applied to various busbars and bus ducts, using distributed fiber optic measurement technology for real-time temperature monitoring, thereby achieving safe monitoring of the operation of busbar equipment.
