Description

Technical Field

[0001] The present invention relates to the technical field of leakage current detection, and in particular to a leakage current detection device. Background Art

[0002] Leakage current detection is the current generated by leakage in the circuit due to insulation damage or other reasons. Currently, leakage current detection is mainly carried out through electronic multimeters and clamp meters.

[0003] For example, a Chinese patent with publication number CN216718653U discloses a leakage current test device for power detection, including a multimeter, a lifting assembly and a shoulder strap, the lifting assembly includes a chassis, a wire shaft, a double-threaded sleeve and an internally threaded sleeve, the upper end of the chassis is fixedly connected to the wire shaft, the upper end of the wire shaft is threadedly connected to the double-threaded sleeve, the upper end of the double-threaded sleeve is threadedly connected to the internally threaded sleeve, the upper end of the internally threaded sleeve is detachably connected to the multimeter, the upper end of the multimeter is equipped with a handle, and the shoulder strap includes a connecting belt A, Velcro A, a connecting belt B and Velcro B;

[0004] The technology recorded in this scheme rotates the wire shaft and the double-threaded sleeve, causing the wire shaft and the double-threaded sleeve to rotate relative to each other and then perform a thread feeding motion. When the double-threaded sleeve and the internally threaded sleeve are rotated, the double-threaded sleeve and the internally threaded sleeve perform a thread feeding motion, which facilitates the adjustment of the working height of the device. The chassis plays a bottom support role, solving the problem that the previous leakage current test device could not adjust the height according to actual test needs and had insufficient applicability. However, when this scheme is used, the efficiency of adjusting the height of the rotating wire shaft and the double-threaded sleeve is low, affecting the user's detection efficiency.
