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. לכן, 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, בידוד גבוה, 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 distributed fiber optic temperature measurement technology and infrared temperature measurement technology. ביניהם, 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 מערכת למדידת טמפרטורה בסיב אופטי 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, ציוד מיתוג מתח גבוה, high-voltage busbars, cable heads, וכו. 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 טכנולוגיה, 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, יציבות, and simple operation. The entire system operates reliably in harsh environments such as high temperature, high pressure, שדה מגנטי חזק, 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.
