Hot-line work method for 10-kV distribution line and equipment

Abstract

The invention, which belongs to the technical field of distribution hot-line work, relates to a hot-line work method for a 10-kV distribution line and equipment. The method comprises: an operator places an insulating shielding tool at a left-side charged conductor and grounding body by using an insulating operation bar and an insulting shielding tool of a right-side charged conductor and grounding body is installed by using the same method; the operator returns to the ground and an insulating trestle ladder is moved to the ground corresponding to an operating position; the operator climbs the insulating trestle ladder again, approaches the operating position, and carries out hot-line work by using the insulating operation bar; during the working process, the operator keeps a minimum safety distance of at least 0.6m with an electrified body and keeps a minimum safety distance of at least 0.4 m with the ground; and the whole working process is monitored by a specially-assigned person. According to the invention, the method is suitable for hot-line work for a 10-kV distribution line and equipment in narrow space; and on the premise that the safety of the operator is ensured, high-efficiency work is carried out under the circumstance that the power of the 10-kV distribution line and equipment is not interrupted.

Description

technical field [0001] The invention relates to a live working method applied to 10kV power distribution lines and equipment with narrow working space, 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. At present, the live work of power distribution has been widely carried out in China, and the live work is mainly carried out by insulated bucket trucks. When the 10kV insulated bucket arm truck performs live work, its working height shall not be lower than 3.5 meters; in the actual working environment, the height of some 10kV power distribution lines and equipment maintenance operations is only 3 meters or even low...

Problems solved by technology

When the 10kV insulated bucket arm truck performs live work, its working height shall not be lower than 3.5 meters; in the actual working environment, the height of some 10kV power distribution lines and equipment maintenance operations is only 3 meters or even lower, and due to the narrow working space, resulting in The 10kV insulated arm truck cannot carry out the operation

[0003] In view of the above problems that 10kV insulated bucket trucks cannot effectively carry out live work due to the limitation of working height and space, it is necessary to provide a live working method for 10kV power distribution lines and equipment with narrow working space to ensure safe and effective implementation of the work
