As the power system continues to expand, cables, like capillaries, are densely distributed throughout cities, villages, and factories. While bringing convenience to people’s lives and production, frequent cable faults have become a major hidden danger affecting the stable operation of the power system. Fires caused by cable short circuits and overloads occur frequently, and power outages not only affect people’s lives but also threaten the safe production of enterprises. Because fault points are hidden, traditional manual inspections are difficult, slow, and costly; sometimes locating a fault can take more than a week, seriously impacting people’s livelihoods and economic operations.
To solve this problem, TBEA Electric Equipment Group’s Delan Cable Company has successfully developed a distributed fiber optic temperature measurement intelligent early warning cable system solution through independent innovation. This solution constructs a complete “sensing-analysis-early warning-response” full-chain protection system composed of OPMC optoelectronic composite cables, DTS temperature measurement hosts, and an intelligent AI integrated management platform. It enables real-time and accurate monitoring of cable operating status, preventing short circuits, overloads, and breakdowns from the source, providing a brand-new solution for power safety.
Compared to traditional cables, this system solution offers three main functions: real-time line temperature monitoring, temperature anomaly alarms, and precise anomaly point location.
Firstly, at the source, the OPMC optoelectronic composite cable’s conductor uses multi-strand fine oxygen-free copper wire strands. Besides its excellent flexibility, conductivity, and heat resistance, its most important feature is its deep integration of sensing capabilities into traditional power transmission cables. This allows it to continuously and in real-time capture subtle changes during cable operation, focusing on monitoring temperature anomalies and mechanical stress (such as vibration). Built-in distributed temperature-sensing optical fibers enable uninterrupted real-time temperature monitoring. Simultaneously, a dedicated independent data transmission channel ensures that the original state signals, such as temperature distribution and mechanical stress, acquired by the sensing layer are transmitted to the maintenance terminal platform without loss and in real-time, enabling real-time perception of the cable’s operating status.
According to reports, the distributed fiber optic temperature measurement intelligent early warning cable system solution possesses multiple core advantages. Its temperature measurement accuracy reaches ±1℃, and its positioning accuracy is up to ±0.05 meters. It covers a wide temperature range from -60℃ to 150℃, supports continuous remote monitoring over a distance of ten kilometers, and also features historical data retrieval and data analysis functions. Its alarm temperature zones can be flexibly set, it is compatible with various operating systems such as LINUX and Windows, and can import real-time visuals, making the cable’s operating status intuitively visible. It boasts extremely high reliability and adaptability.
Currently, this solution has been widely applied in various scenarios such as data centers, high-rise buildings, urban power distribution networks, high-voltage power grids, and rail transit. The company can provide customized development services based on customer needs, along with turnkey projects integrating installation, commissioning, and operation and maintenance, comprehensively meeting the power safety assurance needs of multiple scenarios, fundamentally preventing cable fault risks, and safeguarding the stable operation of the power system.
