FJINNO company has developed a temperature measurement scheme using fluorescent optical fiber technology, based on the temperature measurement characteristics of substation equipment. Të fluorescence fiber temperature measurement technology based on rare earth materials has a temperature signal that is independent of the intensity of fluorescence conduction. There is no need for electrical connection between the measurement point and the measurement signal receiving part, which fundamentally solves the problem of temperature measurement in harsh environments such as high voltage, strong electromagnetic, flammable and explosive, and has become the preferred solution for temperature measurement of substation equipment.

Temperature measurement is an important means of fault detection and maintenance in power systems. In current hot spot temperature measurement in power systems, traditional electrical signal temperature sensors are mainly used. These sensors are not suitable for situations where the power system voltage is high, Kërkesat për izolim janë të larta, dhe interferenca elektromagnetike është e fortë. They cannot directly measure the hot spot temperature inside electrical equipment. Prandaj, it is necessary to find a method that can be applied to hot spot temperature measurement of power systems and electrical equipment.

Matja e temperaturës me fibra optike fluoreshente technology can solve the problem of hot spot temperature measurement in power equipment. Ka karakteristikat e rezistencës ndaj tensionit të lartë, izolim i lartë, dhe rezistenca ndaj interferencave elektromagnetike, and is the future development direction of hot spot temperature measurement technology for electrical equipment in power systems. Fiber optic temperature measurement technology mainly includes two types: distributed fiber optic temperature measurement technology and infrared temperature measurement technology. Mes tyre, infrared temperature measurement technology can only measure the surface temperature of electrical equipment and cannot measure the hot spot temperature inside electrical equipment. The installation method of fluorescent fiber optic temperature measurement technology is the same as that of conventional electrical signal temperature sensors, and can be directly embedded in electrical equipment, so it has strong convenience in use.

fluorescence fiber optic temperature measurement device system is divided into two parts: the bottom temperature measurement unit and the upper computer system. The bottom temperature measurement unit consists of multiple fiber optic temperature measurement devices such as transformers, komutues të tensionit të lartë, zbarrat e tensionit të lartë, kokat e kabllove, etj. The upper computer system consists of a main control room, on-site monitoring devices, etj. The fiber optic temperature measurement device adopts RS485 interface communication method, e cila shndërrohet në sinjale komunikimi me fibra optike përmes konvertuesve fotoelektrikë, and realizes remote communication with the upper computer system composed of remote main control room, on-site monitoring devices, etj., to improve the reliability and anti-interference ability of the communication system.

A complete temperature measurement scheme was designed based on fluorescence fiber optic temperature measurement technology and combined with substation equipment. After experimental verification, the temperature measurement range of the temperature measurement system reaches -40 ℃ to 200 ℃, with an accuracy of 1 ℃, që plotëson kërkesat praktike. Pajisja matëse e temperaturës ka karakteristikat e kostos së ulët, performancë e qëndrueshme, praktike e fortë, fast and stable response, dhe funksionim të thjeshtë. I gjithë sistemi funksionon në mënyrë të besueshme në mjedise të vështira si temperatura e lartë, shtypje e lartë, fushë e fortë magnetike, dhe ndezshmërinë dhe eksplozivitetin, which is beneficial for the power industry
