[0002] With the development of the power system, the number of oil-free electrical equipment such as bushings and transformers is increasing. The number of such equipment is large, the probability of various failures is high, the size is relatively small, the oil volume is small, the voltage is high, the field strength is concentrated, and most of them are in a sealed state without explosion-proof devices. Once a serious thermal failure occurs and is not discovered in time, it may develop into a serious accident and even endanger the main equipment or adjacent equipment, posing a direct threat to the safe and stable operation of the power system.

[0106] In the embodiment of the present invention, big data technology is adopted to integrate the massive data such as pressure, temperature, load, etc. accessed by sensors across Xinjiang, and realize one-stop data analysis, so as to provide observation and analysis data for all levels to grasp the overall operation status, development trend and fluctuation law of equipment, provide more support for information query and statistics of managers at all levels in their daily work, and provide auxiliary basis for equipment maintenance.

[0107] Through the external Internet interface, future weather and temperature data can be obtained. When a certain amount of abnormal data is accumulated in the later stage, artificial intelligence and big data are fully applied to establish a fault prediction model for accurate prediction. Through deep learning, emergency plans and similar fault cases are automatically recommended to achieve intelligent operation and inspection.

[0108] Analyze the operating rules of equipment according to climate and season changes, and provide scientific guidance. That is, according to the 24 solar terms, summarize the historical data of the equipment in sections, summarize the data characteristics, discover the operating rules under different solar terms, and give scientific guidance in advance before the next solar term arrives to effectively prevent predictable risks.
