Ang pinakamahusay na paraan ng pagsukat ng temperatura para sa mga cable joints sa power supply systems-INNO

Mayroong ilang mga paraan ng pagsukat ng temperatura para sa power supply system
Ang power supply system ay nagdadala ng transmission at energy conversion ng electrical energy, at ang pag-init ay nasa lahat ng dako sa buong sistema, proseso, and every link. In a stable power supply system, maraming pag-init ay hindi sanhi ng matinding short-circuit currents, but by equipment and line aging, excessive resistance at circuit connection points, o matagal na operasyon sa isang kapaligiran na may mahinang pag-aalis ng init. 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: mga contact sa circuit breaker, copper bars and copper bar connection points, primary cables and cable connections, transformer cores, rectifier diodes, atbp. 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. Mula dito, it can be seen that various existing temperature measurement methods have significant limitations.

Paglalapat ng Fluorescent Fiber Optic Temperature Measurement System sa Power Industry

Ang power supply system ng fluorescent fiber optic temperature measurement device ay nag-i-install ng maramihang fluorescent fiber optic probe na mga punto ng pagsukat ng temperatura sa mga pangunahing bahagi ng 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.

Ang sistema ng pagsukat ng temperatura ng fiber optic ay maaaring magsagawa ng online na pagsubaybay sa temperatura at pagsusuri sa mga pangunahing bahagi ng kagamitan sa suplay ng kuryente sa sistema ng suplay ng kuryente. Para sa mga espesyal na solidong bahagi ng mataas na temperatura ng kagamitan sa suplay ng kuryente, precise temperature measurement is achieved through pre embedded installation, at ang temperatura sensor ay may magandang anti-interference effect sa pamamagitan ng pagpapadala ng mga optical signal. Kasabay nito, the temperature sensor has high accuracy, temperature measurement range, pagiging maaasahan, at katatagan. 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. Kasabay nito, 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.
