Technical Field

[0001] The invention belongs to the field of cable detection, and in particular relates to a cable grounding fault indicating device connected to an insulator. Background Art

[0002] A ground fault occurs when a cable conductor accidentally touches the ground or other grounding body, causing current to flow to the ground. This fault may cause instability in the power grid or even lead to more serious accidents. Therefore, it is crucial to quickly and accurately detect and locate ground faults.

[0003] At present, during the installation of cables, cable tensioners are used to fix the cables on the top of insulators. During operation, fault indicators are usually installed on the cables to monitor the operating status of the cables in real time so that quick processing can be carried out when a cable fault occurs.

[0004] Existing fault indicators are often installed after the cable is installed, which results in different installation times for the tensioner and the fault indicator, requiring electricians to perform two high-altitude installations, increasing their workload.

[0005] Therefore, we propose a cable grounding fault indication device connected to an insulator to solve the above problems. Summary of the invention

[0006] In view of the problem that the existing fault indicators are often installed after the cable is erected, which results in different installation times for the tensioner and the fault indicator, requiring electric workers to perform two high-altitude installations, increasing the workload of electric workers, the present invention provides a cable grounding fault indicator device connected to an insulator.
