Embodiment Construction
[0036] The method for generating the calibration pulse for detecting the partial discharge of high-voltage power equipment proposed by the present invention can have two different working modes, wherein the first working mode includes the following steps:
[0037] (1-1) Set the calibration pulse output mode as asynchronous mode;
[0038] (1-2) setting the amplitude and output repetition frequency of the calibration pulse;
[0039] (1-3) read the amplitude of the calibration pulse set above, and convert the amplitude of the calibration pulse into a low-voltage DC analog signal after digital-to-analog conversion;
[0040] (1-4) amplifying the above-mentioned low voltage direct current analog signal to become a high voltage direct current analog signal;
[0041] (1-5) Read the output repetition frequency of the calibration pulse set above, obtain the output repetition interval time Δt of the calibration pulse according to the output repetition frequency, and output a control pul...
