Embodiment Construction
[0008] A method for transforming the distribution network in rural alleys, which is realized by the following steps: 1) First grid the lines in the station area, that is, divide the lines in the station area into several grids according to the rural geographical environment and the distribution of low-voltage lines Grid, the low-voltage lines in the grid can be interconnected, choose a grid in the station area, (before construction, the technicians will consider all factors to select a first construction area); 2) Remove the old line; 3) Excavate The foundation of the old pole; 4) Remove the old pole; 5) Set up a new pole at the original position of the old pole; 6) Set up the fittings for the new pole; 7) Erection of a new line.
[0009] In step 2), pre-secure the old poles before removing the old wiring. This is because when removing the old lines, it will inevitably cause the old poles to loosen. In order to avoid unnecessary troubles, the old poles should be fixed in advan...

The invention relates to a transformation method of a power distribution network, and especially relates to a method for transforming a power distribution network in a rural alley. The method solves the problems that when a conventional rural power distribution network transformation method is adopted, new lines and old lines are mixed in the rural alley, potential safety hazards are great, the commissioning period of the new lines is long, and ancient village sites are damaged. The invention provides a method for transforming the power distribution network in-situ on the original poles in therural alley. The method is implemented according to the steps of selecting a transformer area grid, removing old lines, excavating the foundation of old poles, removing old poles, assembling new poles at the original positions of the old poles, assembling hardware fittings of the new poles, and erecting new lines. According to the power distribution network transformation method adopted by the invention, the old foundation only needs to be excavated once in a project, the total construction cost of the project is reduced, the construction period is shortened, the old poles are dismantled on the same day, the new lines are put into operation on the same day, the new lines and the old lines are not mixed in power supply, the potential safety hazards are reduced, and especially when the ancient village sites are transformed, the original sites are not damaged.
Description
technical field [0001] The invention relates to a method for transforming a distribution network, in particular to a method for transforming a distribution network in a rural alley. Background technique [0002] In order to meet the needs of local transformation and development and the people's better life, in recent years, the State Grid Corporation of China has stepped up efforts to transform the distribution network, and the task of power grid construction has become increasingly arduous, and the construction schedule is tight. [0003] When the conventional rural distribution network is transformed, the construction process is to excavate the foundation near the original pole, erect the new pole, assemble the fittings, erect the new conductor, fix the old pole with a tripod, remove the old conductor, excavate the foundation of the old pole, The old poles were dismantled, and finally the new line was put into operation with live electricity. During the construction proce...
