Abstract
The utility model relates to a short-circuit fault indicator used for a switch cabinet and a ring main unit, which is directly installed on a cable when in use. The fault indicator consists essentially of a sensing device, a logical judgment and control device, and an indicator light, wherein the sensing device measures the changes of magnetic field and electric field in a distribution circuit, and outputs a signal to the logical judgment and control device; and the logical judgment and control device analyzes and processes the signal, and then outputs a corresponding display signal to the indicator light. When a circuit fault occurs, the fault indicator indicates a fault path through stroboscopic light of the indicator light, so as to clearly show an outgoing line, branch and section where the fault is positioned for track walkers, thus avoiding blind line tracking, reducing the power failure time, and improving the reliability of power supply.
