Low-voltage power distribution network full-type line leakage current detection device and method

The invention provides a low-voltage power distribution network full-type line leakage current detection device and method, and the device comprises a detector and a mobile detection mechanism, the detector is connected with the mobile detection mechanism through a lead, and the mobile detection mechanism is used for being installed on a to-be-detected line and can move along the to-be-detected line; a moving mechanism of the mobile detection mechanism moves along a to-be-detected line, so that an area which is not easy to reach by detection personnel can be effectively detected for electric leakage detection, and the magnetic end face can adaptively adjust the opening size of the U-shaped structure according to the size change of the to-be-detected line, so that the device adapts to road sections with different sizes of the to-be-detected line. And the telescopic part on the moving mechanism can effectively adjust the shrinkage size so as to ensure the stable operation of the moving mechanism, and the moving
