SYSTEM FOR MONITORING CIRCULATING CURRENT OF HIGH-VOLTAGE CABLE METAL SHEATH

The invention belongs to the technical field of cable monitoring, and particularly relates to a monitoring system for circular current of a high-voltage cable metal sheath. The monitoring system comprises a mobile vehicle, wherein a lifting assembly is mounted on one side of the mobile vehicle, a pushing assembly is horizontally mounted at an end, stretching out of the top of the mobile vehicle, of the lifting assembly, a detection assembly is connected to an end, away from the lifting assembly, of the pushing assembly and comprises a detection mechanism fixedly connected with an output end of the pushing assembly, and a protection mechanism is connected to one side of the detection mechanism. The design of the invention can fulfill automatic and rapid detection of circular current of a cable metal sheath and can automatically jump over a bracket for mounting a cable during detection; debris such as dust is effectively prevented from entering the detection mechanism in operation, and the protection function and quality are improved; the circular current of a ground cable metal sheath can be easily detected, the defection efficiency is improved, and labor intensity is relieved.
