Live pole erecting method for 10 kV common-tower double-circuit and vertically arranged power distribution line

Abstract

The invention relates to a method for erecting poles for a 10 kV common-tower double-circuit and vertically arranged urban power distribution line in a live way. A live pole erecting method for the 10 kV common-tower double-circuit and vertically arranged power distribution line is characterized by comprising the steps of mounting an insulation shielding and pulling tool for live wires of the power distribution line; pulling the live wires of the power distribution line; according to the sequence from bottom to top, enabling a second operation person to pull the live wires with various phases by using an insulated rope in sequence; ensuring that the distance between same-phase live wires of a first operation power distribution line and a second operation power distribution line is not less than 2.5 m; erecting poles; mounting and shielding the new erected poles; mounting the wires with various phases on the new erected poles; and detaching the insulation shielding and pulling tool for the live wires of the power distribution line. Through adoption of the live pole erecting method for the 10 kV common-tower double-circuit and vertically arranged power distribution line, provided by the invention, live operations can be guaranteed to be safely and effectively implemented.

Description

technical field [0001] The invention relates to a method for implementing a live pole for a 10kV double-circuit erection on the same pole in an urban area and adopting a vertical arrangement mode, and belongs to the technical field of power distribution live work. Background technique [0002] 10kV distribution lines and equipment are an important part of my country's power grid. Live work on 10kV distribution lines is one of the important means to reduce the power outage time of the distribution network and improve the reliability of power supply and high-quality service levels of the distribution network. Due to the shortage of land resources in urban areas, a large number of double-circuit or even multi-circuit distribution lines are erected on the same pole in the urban distribution network. In addition, various communication lines are attached to the poles, resulting in no existing poles. The location where the lower conductors are installed has brought great trouble to...

AI Technical Summary

Problems solved by technology

If the pole operation is carried out in the way of power outage, it will adversely affect the normal production and domestic electricity consumption of users, and it is necessary to implement live pole operation

However, the existing live pole method cannot fully meet the requirements of double-circuit or even multi-circuit live pole operation for distribution lines erected on the same pole, especially in urban areas where the environment is complex, there are many distribution lines erected on the same pole, and communication lines are dense. Therefore, it is necessary to provide a method for carrying out live poles under multi-circuit distribution lines in urban areas to ensure safe and effective implementation of operations.
