O melhor método de medição de temperatura para juntas de cabos em sistemas de alimentação-INNO

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, processo, 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. Os principais componentes incluem: contatos do disjuntor, copper bars and copper bar connection points, primary cables and cable connections, transformer cores, rectifier diodes, etc.. 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. A partir disso, it can be seen that various existing temperature measurement methods have significant limitations.

Aplicação de Sistema de medição de temperatura de fibra óptica fluorescente 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. Ao mesmo tempo, the temperature sensor has high accuracy, faixa de medição de temperatura, confiabilidade, e estabilidade. 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. Ao mesmo tempo, historical data is statistically analyzed to form a historical curve, e uma grande quantidade de dados históricos é usada para avaliar se o status de operação de carga do equipamento de fonte de alimentação é normal.
