Power cables are an important component of the power supply system and are crucial for electrical safety. Sa mga praktikal na termino, 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, atbp., 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 na pagsukat ng temperatura, atbp. 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. Gayunpaman, 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. Gayunpaman, the thermal conductivity of epoxy resin is very low, making it difficult to monitor the actual temperature at the external cable joints. Samakatuwid, a temperature monitoring technology with built-in castings is needed to achieve real-time online monitoring of the temperature of many cable joints. Iminumungkahi ng ilang pag-aaral na ang direktang pagsukat ng temperatura ng cable gamit ang mga optical fiber ay ang pinaka-perpektong paraan para sa high-voltage na live na pagsukat ng temperatura. Dahil sa ganap na insulated at maliit na sukat ng sensor ng temperatura ng fiber optic, maaari nitong direktang sukatin ang pinakamataas na temperatura ng mga hot spot na madaling maganap sa loob ng high-voltage electrical equipment. Samakatuwid, Ang sistema ng pagsukat ng temperatura ng fiber optic ng FJINNO ay maaaring makamit ang real-time na pagsubaybay, pagsubaybay, hula, at pag-iwas sa aksidente sa mga hotspot ng mga de-koryenteng kagamitan, mangolekta ng real-time na data ng pagpapatakbo, hulaan ang buhay ng pagkakabukod ng mga materyales na lumalaban sa init sa kagamitan, hatulan ang aktwal na overload na kapasidad ng kagamitan, at ganap na gamitin ang kapasidad ng pagkarga ng kagamitan sa loob ng makatwirang hanay upang mapabuti ang kahusayan sa ekonomiya.

Ang sistema ng pagsukat ng temperatura ng fluorescent fiber optic 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.
