Large-scale overhauling method of high-voltage electrical equipment

Abstract

The invention discloses a large-scale overhauling method of high-voltage electrical equipment. Operation procedures are subdivided through scientifically dividing functions of an equipment overhauling operation region by using an organization method of trial guide and then complete spreading; and a working-at-height mobile platform is constructed by applying a modern operation device, and the site factorized equipment overhauling method of an assembly line is formed on a transformer substation overhauling site. Through implementing the method, the layout of the traditional disordered transformer substation construction site is changed, and an original overhauling mode of operating from the beginning to the end is changed, thus an operator more skillfully operates and controls the procedures. By means of the modern operation device, mechanization operation is widely developed, thus the site safety management and control level is improved, the operation time is effectively shortened, and the overhauling quality is improved.

Description

technical field [0001] The invention belongs to the technical field of high-voltage equipment maintenance, and in particular relates to a large-scale maintenance method for high-voltage electrical equipment. Background technique [0002] With the rapid construction and development of the power grid, due to the natural aging of electrical equipment and the upgrading of the power grid, many high-voltage electrical equipment need to be overhauled after reaching a certain operating life. There are mainly electrical equipment such as high-voltage circuit breakers, disconnectors, and current transformers. In the large-scale technical renovation and maintenance projects of substations, there are often problems such as large construction period span, many tasks, many work areas, many on-site personnel and vehicles, and many cross-operations. On-site construction safety risk management and construction quality control also encounter difficulties to varying degrees . In the past, in...

Problems solved by technology

In the large-scale technical renovation and maintenance projects of substations, there are often problems such as large construction period span, many tasks, many work areas, many on-site personnel and vehicles, and many cross-operations. On-site construction safety risk management and construction quality control also encounter difficulties to varying degrees

In the past, in the maintenance work of high-voltage electrical equipment, there was no systematic organization method that carried out pilot projects first and carried out comprehensively. Instead, it blossomed everywhere at one time. It was difficult to formulate a relatively complete treatment method for various problems that occurred during maintenance, and the management form was relatively extensive.

At the substation equipment maintenance site, the working area has not been functionally divided scientifically, resulting in poor connection between processes; due to the limitation of the number of people working at heights, most of the ground workers cannot fully play their roles, and the workers at heights are restricted by vehicles. Fast flow, lack of modern handling equipment at the maintenance site, and low efficiency; in addition, the operators do not subdivide the operation procedures during the equipment maintenance, and the maintenance personnel often work from the beginning to the end. Due to the different mastery of the entire process, the entire maintenance operation is affected time, the overhaul site has chaotic management, low operating efficiency, sharply increased pressure on safety risk control, and uneven operating quality
