With the emergence of new technologies such as digital power grids, cable lines are becoming increasingly large, and therefore cable line faults have become a focus of attention. The surface temperature of power cables reflects the operation of the cables, the actual operating load of the cable system, and the occurrence of anomalies are closely related to the temperature of the cable system. بنابراین, temperature monitoring of power cables has become a key research topic today. Due to factors such as the production quality of cables, the scheduling level of operating units, and the current majority of cable monitoring devices, the average cable failure rate in China is higher than that in countries such as Europe and America. بنابراین, studying an effective temperature monitoring system for power cables can take timely measures to prevent accidents from occurring.

The long-distance distributed fiber optic temperature sensing system (DTS) adopted by FJINNO can detect faults in power cables. Once it is found that the measured environmental temperature value exceeds the upper and lower limits of the standard alarm temperature, the long-distance فیبر نوری توزیع شده temperature sensing system (DTS) will directly send real-time alarm signals to the monitoring system through communication, and the monitoring system will take relevant measures after confirmation. این distributed fiber optic sensing system has high-quality safety, lightning protection, explosion-proof, و مقاومت در برابر تداخل الکترومغناطیسی; Resistant to adverse environmental impacts and has good tolerance; Can provide real-time online monitoring; Simple construction and maintenance free; The detection part is completely transmitted through optical fiber, که ذاتا برای محافظت در برابر انفجار و صاعقه بی خطر است, و می تواند تأثیر تداخل الکترومغناطیسی را به طور کامل از بین ببرد; The fiber optic cable has excellent durability design, با طول عمر کابل تشخیص تا 30 سال. در برابر اثرات زیست محیطی مانند دما مقاومت دارد, فشار, و نوسانات رطوبت, و همچنین برای هوای با سطوح بالای گرد و غبار و مواد خورنده مناسب است.
