Evaluating method of electric equipment partial discharge detection system and electric equipment partial discharge detection device

The invention provides an evaluating method of electric equipment partial discharge detection system and an electric equipment partial discharge detection device. The method comprises the steps of using a GIS (Geographic Information System) test section to arrange the signal detection of a manual defect evaluating system; evaluating the external synchronization function availability of the system by using a multi-power frequency period simulation voltage signal which is generated by a signal generator, wherein the amplitude of the signal generator is adjustable; evaluating a discharge databank of the system by taking the multi-power frequency period simulation voltage signal as the reference; inputting a sensor direct measurement wave form recovered in mode of equivalent simulation into a partial discharge detection system based on an amplitude difference and a time interval difference so as to evaluate the functions of the system, such as detection sensibility, phase spectrogram, detection type evaluation, tendency analysis and the like; and evaluating the detection frequency band of the system based on the wave form frequency difference. The method has the outstanding advantages of evaluation universalization, key parameter index measurability, comprehensiveness, wide applicability and the like.
