Study on Intelligent Sensing Method of Transformer Non-Electrical Protection

Aiming at the problem of efficiency and accuracy of transformer non-electrical protection data acquisition, a new intelligent sensing method for transformer non-electrical protection has been designed. The four-quadrant diagram method was adopted to distinguish the priority level of nonelectrical protection data acquisition, so as to adopt different strategies for acquisition of different data; the features of collected non-electrical protection data samples was extract, and an intelligent sensing model of transformer non-electrical protection was built to realize the purpose of intelligent sensing of transformer non-electrical protection. The test results showed the proposed method could realize the accurate and intelligent sensing of gas health confidence and transformer failure rate, and meet the design requirements and practical use requirements.
