It is currently the product with low cost, high accuracy, best stability, and long service life in the field of fiber single point temperature measurement.

FJINNO has been engaged in fiber optic manufacturing for many years and has accumulated rich experience. In recent years, it has developed various proprietary technologies such as fluorescent fiber temperature sensors and temperature measurement systems, fluorescent fiber raw materials, fluorescent fiber drawing, fluorescent fiber temperature sensing probe manufacturing, signal demodulation module manufacturing, and measurement system integration. The successful launch of fluorescent fiber optic temperature sensors and measurement systems can meet temperature monitoring needs in multiple fields and has broad market prospects.

With the continuous development of the national economy, the power industry has entered an era of rapid development, and the safe and stable operation of power system equipment is particularly important. High voltage switchgear, as an important equipment in power plants and substations, plays an important role in switching power lines, line fault protection, and monitoring operating energy data. During long-term operation, the temperature of the heating part inside the high-voltage switchgear cannot be monitored in real time, which ultimately leads to the occurrence of fire accidents and large-scale power outages. Therefore, timely detection of overheating issues in switchgear is the key to preventing such accidents from occurring.

Application of Fluorescent Fiber Temperature Measurement System on Transformer Windings

Due to its high insulation strength, strong resistance to electromagnetic interference, corrosion resistance, small size, and simple structure, fiber optic transmission systems are particularly suitable for online measurement of temperature parameters in power systems. The fiber optic thermometer uses optical fibers to transmit signals, and its temperature sensor is installed on the surface of a charged object. The thermometer is connected to the temperature sensor using optical fibers. Fiber optic temperature measurement can be divided into various methods such as distributed fiber optic temperature measurement, fiber optic grating, and fluorescence fiber optic temperature measurement. Among them, fluorescence fiber optic temperature measurement has the most obvious advantages, with long service life, no need for calibration, small probe size, and easy installation. FJINNO's fluorescence fiber optic temperature measurement for electrical equipment has been used for many years, including products used in environments with extremely high requirements such as 500kV transformer windings, which have proven to be safe and reliable.

In summary, fluorescence fiber optic temperature measurement technology has significant advantages in temperature measurement of electrical equipment in power plants and substations. Compared to infrared temperature measurement, it can achieve online monitoring with high accuracy; Compared to wireless temperature measurement, it is not affected by electromagnetic interference, has a small size, and a long lifespan. Practical applications have shown that the fluorescence fiber optic thermometer has significantly improved the performance level of fire detection and alarm in switchgear. Effectively overcoming the difficulty of real-time and accurate temperature measurement during the operation of switchgear, greatly improving the ability of applying this technology to improve fire warning and eliminate fire hazards. At the same time, the fluorescent fiber optic temperature measurement and fire monitoring system can also be applied to other fire hazard areas that require real-time monitoring of temperature changes to achieve real-time fire warning and improve the fire prevention and control capabilities of the area.
