There are several temperature measurement methods for the power supply system
The power supply system carries the transmission and energy conversion of electrical energy, and heating is ubiquitous throughout the entire system, process, and every link. In a stable power supply system, many heating is not caused by severe short-circuit currents, but by equipment and line aging, excessive resistance at circuit connection points, or prolonged operation in an environment with poor heat dissipation. These hidden dangers are difficult to detect through manual inspection, so it is necessary to use temperature measurement methods to monitor key parts of the power supply system. Key components include: circuit breaker contacts, copper bars and copper bar connection points, primary cables and cable connections, transformer cores, rectifier diodes, आदि. Traditional temperature measurement methods of thermal resistors and thermocouples, due to their conductor materials, can cause significant insulation hazards to the power supply system. The infrared temperature measurement method has a higher cost and is easily affected by falling dust. The wireless transmission temperature sensor is powered by a packaged battery, and its service life is only a few years. From this, it can be seen that various existing temperature measurement methods have significant limitations.

It has advantages such as high temperature resistance, strong anti-interference ability, and accurate measurement, providing users with direct dynamic measurement. It has the advantages of direct, वास्तविक समय, and accurate measurement, and is very suitable for direct temperature measurement in high voltage and strong magnetic field environments, while ensuring the insulation performance of high voltage equipment.

Application of Fluorescent Fiber Optic Temperature Measurement System in the Power Industry

The power supply system of the fluorescent fiber optic temperature measurement device installs multiple fluorescent fiber optic probe temperature measurement points in key parts of the power supply system, transmits optical signals through conductive fibers, and then enters the fiber optic temperature measurement host to analyze the corresponding temperature value. The background monitoring upper computer reads the temperature data through dedicated fiber optic temperature measurement analysis software, displays and analyzes the real-time temperature values of various key parts of the power supply system, and forms a historical temperature curve through the database. Through the historical temperature data of the power supply system, big data analysis is conducted on the equipment and lines to diagnose and evaluate the operation status of the power supply system.

The fiber optic temperature measurement system can perform online temperature monitoring and analysis on key components of the power supply equipment in the power supply system. For special high-temperature solid components of the power supply equipment, precise temperature measurement is achieved through pre embedded installation, and the temperature sensor has good anti-interference effect through the transmission of optical signals. एकै समयमा, the temperature sensor has high accuracy, temperature measurement range, विश्वसनीयता, and stability. The fluorescence fiber optic temperature measurement method has a good signal transmission topology structure. After each fiber optic temperature measurement circuit is collected through a fiber optic merging unit, the temperature data is transmitted to the fluorescence fiber optic temperature measurement host through a multi-core optical cable. After the temperature data is processed by the temperature measurement host, it is uploaded to the backend upper computer through the TCP Modbus protocol. The temperature data is displayed and analyzed through the fiber optic temperature measurement analysis software to achieve real-time alarm function. एकै समयमा, historical data is statistically analyzed to form a historical curve, and a large amount of historical data is used to evaluate whether the load operation status of the power supply equipment is normal.
