Description

Technical Field

[0001] The utility model relates to the field of circulating flow detection equipment, in particular to a circulating flow detection equipment. Background Art

[0002] The circulating current of a cable refers to the current generated on the outer conductor (usually a metal sheath) by the current passing through the cable. The circulating current will cause heating of the cable, energy loss, and affect the current carrying capacity and service life of the power system. Therefore, it is necessary to monitor the circulating current of the cable.

[0003] In the prior art, the monitoring of high-voltage cable circulating current is usually achieved by installing a grounding box on the grounding wire of the coaxial cable of the cable sheath, and the grounding box is powered by CT induction. However, this solution requires power off for installation and has problems such as troublesome installation. In addition, the CT power supply method also has the problem of unstable power supply. There are also miniaturized circulating current detection devices that are powered by dry batteries and can be installed on grounding wires of corresponding sizes for measurement. However, when installing grounding wires of different diameters, the connection socket needs to be replaced. Therefore, a fast and accurate detection device that can be used for grounding wires of different diameters is needed. Utility Model Content
