Description

Technical Field

[0001] The utility model relates to the technical field of current monitoring, in particular to a cable grounding current monitoring device with a wire harness structure. Background Art

[0002] A cable ground current monitoring device is a device used to monitor cable ground current. It typically includes a ground current sensor, a data acquisition unit, and a monitoring system. By monitoring the magnitude and changes of the cable ground current, the cable's grounding condition can be monitored in real time, allowing ground faults to be detected and addressed promptly, thereby ensuring the safe operation of the cable system. Patent Grant Publication No. CN208860895U discloses a high-voltage cable ground current monitoring device. This device includes a power supply module and a data acquisition module. The power supply module supplies power to the data acquisition module, eliminating the need for a CT. This device has no startup current requirements and is capable of continuous and stable operation around the clock, regardless of the cable current state. In addition to conventional continuous monitoring, this monitoring device can also capture changes in load current and ground current during cable fault conditions, responding to abnormal conditions such as sudden current changes and temperature rises with timely warnings. This makes the monitoring device more reliable. However, the plug of the cable ground current monitoring device can be unstable during use, which can easily lead to the plug becoming loose.
