The operating environment of power high-voltage testing equipment often involves hazardous factors such as high voltage and high current,which makes it difficult to detect the equipment status.There are many interference factors,resulting in low accuracy of the detection results.To address this issue,a state detection method for power high-voltage testing equipment based on multi feature fusion is proposed.Calculate the maximum cut-off overvoltage of the power high-voltage testing equipment and analyze its corresponding voltage waveform characteristics.By using wavelet decomposition to denoise the ultrasonic signal of the equipment,corresponding signal features are obtained.Extract the field strength characteristics and ultraviolet radiation characteristics of the equipment under ultraviolet pulse environment separately,fuse the extracted multiple features,and perform state detection of the power high-voltage test equipment,obtaining relevant detection results.After testing,it is known that this method has shown high accuracy in the state detection practice of power high-voltage testing equipment,and can meet the practical needs of safe operation and maintenance of power high-voltage testing equipment.
