Abstract
The invention discloses a large-caliber clamp-shaped leakage current meter. The large-caliber clamp-shaped leakage current meter comprises a casing body, a display and a rotation adjustment disk with a detection function, wherein the display and the rotation adjustment disk are arranged on the casing body. A clamp-shaped detection end is arranged on the casing body. The clamp-shaped detection end comprises a large-caliber clamp body. A recessed hole is arranged in the clamp-shaped inner face of the large-caliber clamp body. A telescopic column body is arranged in the recessed hole. A small-caliber clamp body is arranged at the end part of the telescopic column body. A buffer pressure spring and an adjustment cylinder are arranged between the telescopic column body and the recessed hole. A piston shaft of the adjustment cylinder is connected with the telescopic column body. An adjustment knob which is connected with the adjustment cylinder is arranged on the casing body. The small-caliber clamp body stretches in the recessed hole under the action of the adjustment knob. According to the invention, the large-caliber clamp-shaped leakage current meter has the advantages of simple structure and easy use, and can effectively detect leakage current; the small-caliber clamp body is arranged in the clamp face of the large-caliber clamp body; the needed clamp body can be selected for detection according to needs; the applicability and the practicality are greatly improved; and the large-caliber clamp-shaped leakage current meter has the advantages of good use stability, high applicability and good practicality.
