Description

Technical Field

[0001] The utility model relates to the technical field of cable detection, and more specifically, to a nondestructive detection device for high-voltage cables. Background Art

[0002] High-voltage power cables are essential materials for modern life and industrial electricity transmission. If there are defects inside the power cables, it will bring great safety hazards to the safe operation of the power cables. Moreover, most power cables are buried underground in a harsh operating environment, making maintenance and fault detection difficult. Therefore, non-destructive testing of high-voltage power cables before they are put into operation is very necessary.

[0003] At present, the commonly used method for the detection of high-voltage power cables is to conduct a withstand voltage test. This method mainly applies a certain test voltage to the cable to observe whether the cable can fully withstand the test of this voltage, so as to preliminarily judge whether the cable has defects. However, this method focuses more on the overall performance of the cable, and is not accurate enough for the integrity detection of the cable sheath insulator. The cable sheath insulator is an important barrier to protect the cable core. Once damaged, it will not only lead to a decrease in the electrical performance of the cable, but more importantly, it may expose the cable core. Once the exposed core is exposed to the external environment, especially when the human body accidentally touches it, it is easy to cause an electric shock accident, causing serious personal injury or even death. Therefore, this paper is committed to a new type of non-destructive testing device for high-voltage cables. Utility Model Content

The detected cable is finally reeled up by the reel-up roller 18;

[0035] The power of motor 14 makes the bidirectional screw rod 1 5 and the bidirectional screw rod 2 6 rotate synchronously. Due to the use of belt 13, the remaining bidirectional screw rods 1 5 and bidirectional screw rods 2 6 also rotate synchronously, so the socket plates 1 7 and socket plates 2 9 on the surfaces of the bidirectional screw rods 1 5 and the bidirectional screw rods 2 6 move relative to each other.
