Description

Distribution network electrified 3D scanning measuring tool

Technical Field

The cable laying of the transmission and distribution line is generally classified into overhead laying and direct-buried underground laying, and the cost of the cable laid overhead is higher than that of the underground direct-buried line, but the cable has to be laid in an overhead manner because the limitation of the geographical environment and the surrounding natural environment does not allow the prevention of the underground direct-buried line. Because the overhead mode lays the general operation environment of cable is relatively crude, the cable is broken down at the operation scene of laying the cable because of the collision of some tools or workers under unconscious circumstances, and the phenomenon that the electric leakage can take place at a certain point or a plurality of points of cable to overhead conductor is in environments such as sunshine, rainwater, sand wind for a long time, and the unavoidable phenomenon that ages and erodes also can take place to break. Resulting in easy accidents during operation. The construction mode of the underground direct-buried high-voltage cable is more economical, and is widely adopted by various power enterprises. However, the disadvantage is that after a certain period of operation, the sheath of the high-voltage cable buried in the ground is often scratched by mice or damaged by other external forces, so that the insulation performance is reduced, then the one-point grounding of the shielding layer is changed into multi-point grounding, and the phenomenon that circulation heating occurs at one point easily causes the cable to be burnt, so that the electric power accident is caused. And great safety risks are brought to the safe operation of the power transmission of the power enterprise.

Under the condition that the electric power demand is larger and larger under the continuous increase of the economy in China, how to ensure the safe operation of the electric power is a problem, whether the electric power is laid in an overhead or directly buried underground, the damage of the insulating layer of the cable sheath can not be found in time, and the electric power has great safety risk in the operation process.
