Temperature measurement is an important means of detecting and maintaining power system faults. In current power system thermal temperature measurement, traditional electrical signal temperature sensors are mainly used in situations where the power system voltage is high, insulation requirements are high, and electromagnetic interference is strong, and cannot directly measure the thermal temperature inside electrical equipment. Þess vegna, it is necessary to find a method suitable for measuring the thermal temperature of power systems and electrical equipment. Fluorescent fiber temperature measurement technology can solve the problem of thermal temperature measurement in power equipment. It has the characteristics of high voltage resistance, high insulation, og rafsegultruflanir viðnám, og er framtíðar tækniþróunarstefna fyrir hitamælingar á rafbúnaði í raforkukerfum. Ljósleiðarahitamælingartækni felur aðallega í sér dreifða ljósleiðarahitamælingartækni og innrauða hitamælingartækni. Meðal þeirra, Innrauð hitamælingartækni getur aðeins mælt yfirborðshita rafbúnaðar og getur ekki mælt innra hitauppstreymi rafbúnaðar. Uppsetningaraðferð flúrljómandi trefjahitamælingartækni er þægileg miðað við hefðbundna rafmerkjauppsetningu og hægt er að fella hana beint inn.
Hið ljósleiðara hitamælingarkerfi skiptist í tvo hluta: neðsta hitamælieiningin og efra kerfið. The bottom temperature measurement unit consists of multiple temperature measurement fiber optic temperature measurement devices such as transformers, háspennurofabúnaður, high-voltage busbars, cable heads, o.s.frv. The computer system consists of a main control room and on-site monitoring devices. The fiber optic temperature measurement device adopts RS485 interface communication mode, which is converted into fiber optic communication signals through photoelectric converters. The remote control room and on-site monitoring device achieve remote communication, improving the reliability and anti-interference ability of the communication system.
On the basis of fluorescent fiber temperature measurement technology, a complete temperature measurement scheme was designed in combination with substation equipment. Through experimental verification, the temperature measurement system has a temperature measurement range of 0-200 ℃ and an accuracy of 0.5 °C, which meets practical requirements. The temperature measuring device has the characteristics of low cost, stable performance, strong practicality, fast response, stability, and simple operation. The entire system operates reliably in harsh environments such as high temperature, high pressure, strong magnetic field, and flammability and explosiveness, and has strong targeting for temperature measurement environments in the power industry. After a large amount of testing data and practical verification results, it is suitable for the field of temperature measurement of power equipment.
