Embodiment Construction

[0023] The concrete implementation of the present invention is described in detail below, it is necessary to point out here that the following implementation is only used for further description of the present invention, and can not be interpreted as limiting the protection scope of the present invention. Some non-essential improvements and adjustments still belong to the protection scope of the present invention.

[0024] The invention provides a quick maintenance method for power distribution lines, which includes the following steps in sequence: figure 1 , 2 As shown, the faulty cables in the distribution line are cut to form the first cable 1 and the second cable 2, and the faulty line parts on the first cable 1 and the second cable 2 are removed; the first cable 1 and the second cable 2 are respectively corresponding The conductor cores 3 are butted, and the butted conductor cores 3 are covered with an insulating material. The insulating material can be an insulating tap...

Abstract

The invention discloses a quick maintenance method for a power distribution line, and the method comprises the steps: fault cable cutting and butt joint, multipoint symmetry and asymmetry radiation measurement, radiation sensing difference calculation, power distribution line fault judgment, the drawing of a curve in a maintenance period, and maintenance completing. The method can achieve the quick maintenance of the power transmission line, measures the quality of a cable line in real time, and enables the power transmission line to be stable after maintenance.

Description

technical field [0001] The invention relates to the technical field of electric power equipment, in particular to a quick maintenance method for power distribution lines. Background technique [0002] With the advancement of science and technology and the rapid development of the economy, the society's demand for electricity has increased rapidly. However, with the continuous development of the distribution network cable process, the distribution network line structure is becoming more and more complex, and there are many branch lines. The requirements for the stability and reliability of power grids are getting higher and higher, and at the same time, users' requirements for power quality and services are also constantly improving. [0003] At present, manual inspection is mostly used for the maintenance of distribution lines, which requires a large number of line inspection and inspection personnel, and when repairing faulty lines, due to line failures and insufficient cab...
