Description

Technical Field

[0001] This utility model relates to the field of cable testing technology, specifically to an automatic cable grounding current detection device. Background Technology

[0002] A cable is an electrical device used to transmit electrical energy or signals. It consists of a conductor, an insulation layer, a shielding layer, and a protective layer. The conductor, usually made of copper or aluminum, is responsible for transmitting current. The insulation layer isolates the conductor from the outside environment and prevents current leakage. The shielding layer reduces electromagnetic interference and improves the stability of signal transmission. The protective layer protects the cable from mechanical damage and environmental factors. Cables are widely used in power systems, communication networks, industrial equipment, and other fields, and are an indispensable basic component in modern electrical engineering. Cable grounding current refers to the current formed between the cable's metal sheath and the ground. When current flows through the cable conductor, a magnetic field is generated around it. Under the influence of the magnetic field, the metal sheath induces an electric potential, thereby forming a current in the grounding system. The magnitude of the grounding current can reflect the health status of the cable's outer sheath. Abnormal grounding current may cause local temperature rise in the cable, accelerate insulation aging, increase line loss, and even cause faults. Therefore, monitoring and controlling cable grounding current is crucial to ensuring the safe operation of cables.

[0003] In existing technologies, many detection devices lack flexible telescopic functions, which means that cable detection at different heights and in different environments requires frequent adjustments to the device position or the use of multiple devices, increasing operational complexity and cost. The assembly and disassembly process of traditional devices is complicated, and maintenance and replacement of parts are time-consuming and prone to damage. Traditional devices can usually only perform fixed-point detection and cannot achieve full coverage of cables, easily overlooking potential grounding current problems. Utility Model Content
