Embodiment Construction
[0017] This embodiment uses the present invention to analyze the content of dissolved gas in power transformer oil.
[0018] Fig. 1 is a principle diagram of the present invention, and Fig. 2 is a detection comparison diagram of the intelligent type and the MQ type sensor of the present invention, as shown in the figure: the mixed gas 1 includes H 2 、C 2 h 4 , CO, C 2 h 2 、CH 4 、C 2 h 6 , after being identified by the gas sensor 2, generate respective response waveforms, obtain and collect the sensor response waveforms, and perform wavelet processing 3 to obtain the characteristic spectra of the above six kinds of gas responses, and obtain the characteristic gas response amplitudes of the specific sensors. Preliminary Enter the input layer of the BP artificial neural network 4 after suppressing the response spectrum amplitude of the cross-sensitive gas, and obtain the content of a single gas by the BP artificial neural network 4; BP artificial neural network 4 uses the m...
