Embodiment Construction
[0036] Such as figure 1 As shown, the specific implementation steps of the intelligent detection method for insulator insulation performance of the present invention are as follows:
[0037] 1) Initialize the zero-value critical resistance R1 and low-value critical resistance R2 of the insulator under test;
[0038] 2) Apply DC high voltage to the insulator under test under power failure state;
[0039] 3) Collect the leakage current flowing through the insulator under test;
[0040] 4) Calculate the insulation resistance R of the insulator under test according to the DC high voltage applied in step 2) and the leakage current collected in step 3) in combination with voltammetry;
[0041] 5) Compare the insulation resistance R calculated in step 4) with the zero-value critical resistance R1 and the low-value critical resistance R2, and then output a comparison result of the performance of the tested insulator.
[0042] In step 5), first compare the insulation resistance R wi...
