The invention relates to a multi-means-integrated charged detection system for a combined electric appliance. The multi-means-integrated charged detection system is technically characterized in that the system comprises an ultrasonic detection unit, a high-frequency detection unit, an ultrahigh-frequency detection unit and a high-speed oscilloscope. The ultrasonic detection unit, the high-frequency detection unit and the ultrahigh-frequency detection unit are arranged on the combined electric appliance, detect corresponding signals respectively and send the detected results to the high-speed oscilloscope. The high-speed oscilloscope finds out various partial discharge defects in the combined electric appliance by detecting and analyzing three partial signals of super-high frequency, high frequency and ultrasonic wave through built-in comprehensive partial discharge analysis and diagnosis software. By means of the multi-means-integrated charged detection system, various partial discharge defects in the combined electric appliance can be effectively detected, the accuracy and reliability of the detection result are improved, and the multi-means-integrated charged detection system has the advantages of being simple in structure, high in sensitivity, convenient to implement and the like and meets the actual application requirement for field detection.
