Description

Technical Field

[0001] This utility model relates to the field of power cable fault testing technology, specifically to a fault testing device for power cables. Background Technology

[0002] Power cables are mainly used for transmitting and distributing electrical energy and are an indispensable and important component of modern power systems. Workers often need to conduct fault tests on various power cables installed on electrical equipment, and leakage current is one of the most common types of faults. However, there are still some defects in the actual operation of such fault testing devices for detecting leakage current.

[0003] When testing for leakage current in power cables, fault testing devices often require the user to hold the leakage current detector and sequentially place it near different locations along the entire power cable. Each leakage point must be manually marked, making it difficult to perform continuous testing and marking of the entire power cable and impacting work efficiency. Furthermore, the leakage current detector and the main unit are connected by wires, making operation inconvenient and lacking flexibility. Therefore, we propose a novel fault testing device for power cables. Utility Model Content

Subsequently, the user only needs to grasp the leakage current tester body so that the two guide clamping arms are clamped on the power cable and slide along it, which facilitates the realization of The device enables continuous sliding detection of the entire power cable. On the other hand, each time the leakage current detector detects a leakage point on the power cable, it sends the detected signal to the host. The control module inside the host then controls the two electric telescopic rods symmetrically distributed on both sides of the leakage current detector to start, causing the mini marker pen at its output end to extend and draw a mark on the power cable. The output end of the electric telescopic rod then retracts. This allows the device to continuously detect and mark multiple leakage points on the entire power cable, which is beneficial for subsequent unified handling of faults on the power cable.

This makes it convenient for the user to hold the main body of the leakage current tester to test the surface of the power cable while flexibly placing the host. This solves the problem of wire tangling and inconvenient operation caused by wired connection, which improves the convenience of device operation. On the other hand, by installing rechargeable lithium batteries inside both the main body of the leakage current tester and the host, both the main body of the leakage current tester and the host can achieve independent power supply function, which makes the device realize the advantage of split operation.

This facilitates continuous sliding detection of the entire power cable. Furthermore, each time the leakage current detector 9 detects a leakage point on the power cable, it sends a signal to the host 3.
