Power cables are an important component of the power supply system and are crucial for electrical safety. In practical terms, there are many faults during cable operation, and there are many reasons for the occurrence of faults. By analyzing the causes of faults and summarizing the fault factors, the quality of operation can be maintained.

Cable joint fiber optic temperature measurement system

Cable faults occur at cable joints, ends, etc., and the manufacturing requirements for intermediate joints are high, so there are many potential problems. The power cable joint is the weakest link in cable safety work. Once the temperature of the cable joint exceeds the critical temperature that the cable can withstand, it will cause the cable joint to catch fire, leading to large-scale power outages. The temperature of cable joints can reflect key parameters of cable joints. By measuring and monitoring the temperature of cable joints, the insulation aging status can be grasped, hidden dangers can be identified in a timely manner, and the safety and quality of cable joint work can be improved, which is of significant significance.

There are many ways to measure temperature in cables, such as thermometers, infrared instruments, infrared imaging equipment, wireless temperature measurement, etc. High voltage cable heads measure temperature through thermometers installed at the lower end of the cable head and transmit it to the terminal through optical fibers. Imidlertid, this high-temperature measurement method is not effective and cannot truly monitor the high temperature in the cable. Due to high insulation requirements, cable joints are usually tightly wrapped with one or more layers of epoxy resin. Imidlertid, the thermal conductivity of epoxy resin is very low, making it difficult to monitor the actual temperature at the external cable joints. Derfor, a temperature monitoring technology with built-in castings is needed to achieve real-time online monitoring of the temperature of many cable joints. Some studies suggest that direct measurement of cable temperature using optical fibers is the most ideal method for high-voltage live temperature measurement. Due to the fully insulated and small size of the fiber optic temperature sensor, it can directly measure the highest temperature of hot spots that are prone to occur inside high-voltage electrical equipment. Derfor, FJINNO’s fiber optic temperature measurement system can achieve real-time monitoring, monitoring, prediction, and accident prevention of electrical equipment hotspots, collect real-time operating data, predict the insulation life of heat-resistant materials in the equipment, judge the actual overload capacity of the equipment, and fully utilize the load capacity of the equipment within a reasonable range to improve economic efficiency.

Den fluorescent fiber optic temperature measurement system can be widely used for efficient online temperature monitoring in fields such as cable joint temperature measurement, dry-type transformer temperature measurement, and power switchgear temperature measurement. Due to the many advantages of built-in fiber optic temperature measurement, it can reduce the incidence of cable failures during use, ensure stable operation, promote industry development, and have significant application value. It is worth promoting and using on a large scale.
