Electrified detector

The utility model relates to electrical equipment operation defect detection and positioning equipment, in particular to a live-line detector which comprises a detector body and a handle, the detectorbody comprises a shell, a visible light camera, an infrared thermal image module, an ultrasonic sensor and a PCB, an inner cavity of the shell comprises a first cavity and a second cavity. Compared with the traditional detector structure, the live-line detector provided by the utility model has the advantages that elements of different modules are arranged in different cavities, the heat insulation effect among the components is good, the non-contact ultrasonic wave, infrared thermal image and temperature detection functions are realized at the same time, the visual detection and positioningof the ultrasonic wave can be realized, and the detection accuracy is improved. Equipment defect detection which does not depend on personnel experience is achieved, the field measurement accuracy isimproved, parts are conveni
