Abstract

The invention relates to a distribution line migration method. The method comprises the steps that towers on a new distribution line are installed, the towers on the new distribution line are connected through wires, a target operation tower is determined according to a distribution line section to be migrated, and a small side of the target operation tower is electrically connected with a large side of the distribution line section to be migrated; an uninterruptible power supply is connected to the large side of the target operation tower, so that the uninterruptible power supply supplies power to a distribution line on the large side of the target operation tower; a connection wire between the target operation tower and the large side of the first tower is switched and connected to the large side of a second tower in the new distribution line, and a power supply path of the new distribution line is connected; and finally, the power supply of the uninterruptible power supply to the power distribution line on the large side of the target operation tower is cut off. Through the distribution line migration method, the power supply of the large-size side distribution line user of the target operation tower during switching can be ensured, and the non-power-cut operation in the distribution line migration process is realized.

Description

technical field [0001] The present application relates to the technical field of distribution line migration, in particular to a distribution line migration method. Background technique [0002] With the rapid development of the economy and the improvement of people's living standards, the demand for electricity continues to rise. Therefore, the previous power system often needs to be renovated or expanded. However, in the process of power system transformation or expansion, it is often necessary to relocate distribution lines. However, the traditional method of relocation of distribution lines will cause long-term or short-term power outages and other problems, which not only affect the user's power consumption experience, but also bring economic production. There are many disadvantages. Contents of the invention [0003] Based on this, it is necessary to provide a power distribution line migration method that can operate without interruption for the power outage technic...
