When a single-phase ground fault occurs on an overhead line, because the location of the fault section cannot be realized, it is difficult to patrol the line, endangering the safety of people and animals, and greatly reducing the reliability of regional power supply.

In order to solve this problem, the fault indicator 100 is usually assembled on the overhead line. Once the line fails, the fault indicator 100 will indicate the type of fault by flashing different indicator lights. As shown in Figure 1 , the fault indicator 100 includes an upper case 101 and a lower case 102 that are rotatably connected, and the upper case 101 can be fastened to the lower case 102, a torsion spring is arranged between the upper case 101 and the lower case 102, and the torsion spring The upper case 101 can be driven to rotate toward the direction of fastening to the lower case 102 . When the upper case 101 and the lower case 102 are snapped together, there is a via hole 103 for the circuit to pass between the upper case 101 and the lower case 102 . However, the diameters of different lines are different. In order to improve the applicability of the fault indicator 100, the lower case 102 is rotatably connected with two clip springs 104, and the rotation directions of the two clip springs 104 are opposite. The other retaining ring 104 has a tendency to rotate, so as to fasten the circuit between the two retaining springs 104 and the lower case 102 .

Because the fault indicator 100 is installed manually, the installer needs to step on a ladder to get close to the circuit, and open the upper case 101 of the fault indicator 100, place the circuit between the upper case 101 and the lower case 102, and then fasten the upper case 101 and the lower case.
