Fluorescence fiber optic is used for temperature measurement in power systems

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 zvinodiwa zvakakwira, uye Electromagnetic kupindira kwakasimba, and cannot directly measure the thermal temperature inside electrical equipment. Naizvozvo, 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. Iyo ine maitiro ezvakakwirira zvekupokana, yakakwira insulation, and electromagnetic interference resistance, and is the future technological development direction for thermal temperature measurement of electrical equipment in power systems. Fiber optic temperature measurement technology mainly includes yakagoverwa fiber optic tembiricha kuyera tekinoroji uye infrared tembiricha kuyera tekinoroji. Pakati pavo, infrared temperature measurement technology can only measure the surface temperature of electrical equipment and cannot measure the internal thermal temperature of electrical equipment. The installation method of fluorescent fiber temperature measurement technology is convenient compared to traditional electrical signal installation and can be directly embedded.
The Fiber Optic Tembiricha Kuyera System is divided into two parts: the bottom temperature measurement unit and the upper system. The bottom temperature measurement unit consists of multiple temperature measurement fiber optic temperature measurement devices such as transformers, Yakakwira-Voltage switchgear, Yakakwira-Voltage bubars, cable misoro, etc. 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, iyo inoshandurwa kuita fiber optic yekutaurirana masaini kuburikidza neThayelectric 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 teknolojia, 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 ℃, izvo zvinosangana zvinodikanwa zvinoshanda. Iyo tembiricha yekuyera mudziyo une hunhu hwemutengo wakaderera, Kuita kwakasimba, Kushanda Kwakasimba, fast response, kugadzikana, uye iri nyore kushanda. Iyo yese system inoshanda yakavimbika munzvimbo dzine hutsinye dzakadai sekupisa kwakanyanya, kumanikidza kwepamusoro, Yakasimba yemagineti munda, uye kupenya uye kuputika, 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.
