Embodiment Construction
[0053] In order to make the technical scheme and design idea of the present invention clearer, we describe it in detail in conjunction with the accompanying drawings.
[0054] The research object is the electric high-voltage switchgear, and the sampling data is the parameter information collected by the sensor in the electric high-voltage switchgear.
[0055] refer to figure 1 , the multi-scale permutation entropy calculation process of the power high-voltage switchgear working condition time series is generally to coarse-grain the time series collected by each sensor in the power high-voltage switchgear, and then perform sequence reordering on the processed coarse-grained sequence. Finally, the permutation entropy value of the sequence is calculated according to the calculation method of permutation entropy, which is the multi-scale permutation entropy value.
[0056] refer to Figure 4 , a method for evaluating the health system of electric high-voltage switchgear based ...
