基于紫外光谱的变压器故障检测方法及装置、介质、设备
By installing an ultraviolet emission detection device in the transformer, the ultraviolet emission of transformer oil is monitored in real time and a spectrum is generated. This solves the problems of lag and insensitivity to components in traditional detection methods, enabling online and real-time monitoring and accurate judgment of transformer faults, and improving the safety and stability of the power grid.

AI Technical Summary
Traditional transformer oil testing methods cannot achieve real-time online detection, making it difficult to detect potential faults in a timely manner. They are also not sensitive enough to changes in oil composition and lack dedicated testing methods and standards.
By using ultraviolet spectroscopy, an ultraviolet emission detection device is installed in the transformer to monitor the ultraviolet emission of the transformer oil in real time, generate a real-time ultraviolet spectrum, and compare it with the fault spectrum to identify the fault type.
It enables online, real-time monitoring and accurate diagnosis of transformer faults, and has functions such as in-situ detection, real-time monitoring, component analysis, quantitative assessment and early warning, which improves the comprehensiveness and accuracy of detection and ensures the safe and stable operation of the power grid.
