Description

A kind of cable joint fault detection equipment

technical field

The utility model relates to the technical field of cables, in particular to a cable joint fault detection device.

Background technique

During the operation of the power grid, the cable joint is the weakest link. About 70% of the cable faults occur at the joint. Therefore, it is very important to accurately and quickly determine the quality and operation status of the joint to ensure the safe and reliable operation of the power grid.

In the current cable joints, the cables in the two cables that need to be docked are mostly butted one by one, wrapped with insulating tape, and then multi-layered with the cables, and then wrapped with insulating tapes in multiple layers. After the cable is connected and heated, it is easy to melt the insulating tape wrapped on the outer layer of the adjacent cable, resulting in a fire and power outage, and there is a certain safety hazard. Moreover, this connection method is not dust-proof and waterproof, so that the cable joints are not protected. Very susceptible to damage. In addition, there is no special detection equipment to conduct real-time detection and positioning of cables that are about to have an accident and cause power outages. During maintenance, multiple cables need to be detected one by one to find the accident point, which is time-consuming and labor-intensive.
