The utility model discloses an intelligent bushing tap leakage current detection and debugging device. A standard source module includes a direct digital frequency synthesizer DDS and a signal amplification circuit. The direct digital frequency synthesizer DDS includes a phase accumulator, a waveform memory, a digital-to-analog converter and a lowpass filter. An output signal of the signal amplification circuit is transmitted to a data acquisition module and a bushing to be detected. A data acquisition card of the data acquisition module is connected with the signal amplification circuit and the bushing to be detected, and receives a signal transmitted from the signal amplification circuit and a bushing tap leakage current signal. A host computer control and data processing module is connected with the phase accumulator, the waveform memory and the data acquisition card. According to the utility model, the problems of poor debugging and calibration flexibility and poor output effects in the prior art are solved, and the intelligent bushing tap leakage current detection and debugging device is integrated with functions of online detection, calibration and debugging, and has the advantages of flexibility, accuracy, practicability and convenience.
