Abstract

The invention discloses an equivalent test method of an old high-voltage cable automatic recovery device, and the method comprises the steps: preliminarily designing an overall three-dimensional model of the old high-voltage cable in Solidworks software according to the characteristics of the old high-voltage cable and a field recovery scene; establishing an equivalent model of the automatic old high-voltage cable recovery device system, and analyzing the working principle of the system and the operation conditions in different recovery scenes; based on the working principle and the operation condition, constructing a stress corresponding relation between the equivalent model and the automatic high-voltage old cable recovery device during normal working; and performing a field cable recovery test by using the equivalent model to obtain a corresponding relation between the rotating speed of the servo motor and the cable recovery speed and the traction force. The failure index and the performance index of the recovery device system can be quickly locked through an equivalent test method, and favorable safety construction guidance is provided for adopting different cable recovery speeds in different recovery scenes, so that the working efficiency is improved, and the labor cost is reduced.

Description

technical field [0001] The invention relates to the technical field of equivalent testing of recycling devices, in particular to an equivalent testing method of an automatic recycling device for high-voltage old cables. Background technique [0002] At present, 110kV and above high-voltage cables have gradually become a particularly important part of urban power grid construction. There are usually three laying methods for laying cables in electric power engineering, which are manual laying, mechanical laying, and mixed laying of manpower and machinery. Due to the characteristics of large cross-section, long distance and heavy weight of high-voltage power cables, human and mechanical laying methods are generally used. When the service life of the cable is too long, the cable will produce faults such as insulation degradation and stress damage, which will threaten the safe operation of the power system and reduce the reliability of power supply. Therefore, it is necessary to...
