Key considerations for distribution line maintenance

Key consideratio​ns for distribution line maintenance

In today's society, the speed of economic development has been greatly improved, while the power system is also indispensable in our daily life. As people put forward higher and higher requirements for the quality of power supply, transmission and distribution lines have also been greatly improved, the safe operation of distribution lines contribute to the rapid development of the national economy and the further improvement of people's lives. However, the distribution line is prone to frequent failure in the case of insufficient power supply, so that it brings great inconvenience to enterprises and people's lives. And in serious cases, there may be security accidents, which threaten personal safety and cause economic losses.

1. Human factors

Construction impact: Municipal construction, construction sites, etc., may cause damage or interference to distribution lines. During maintenance, communicate with related departments to understand the construction plan and progress, and take timely measures to protect the safety of the line.

Traffic factors: Traffic accidents may cause line poles to tilt, break, etc. Therefore, it is necessary to strengthen the traffic safety management near the line, set up warning signs and protective facilities.

User behavior: The user's private wiring, felling trees and other behaviors may cause damage to the line. It is necessary to enhance users' security awareness and legal awareness through publicity, education and supervision.

2. Natural environmental factors

Climate impact: Distribution lines are exposed to the natural environment and are susceptible to severe weather such as lightning, rain, snow, and wind. Therefore, during the maintenance process, pay special attention to weather changes and take appropriate protective measures, such as installing lightning rods and strengthening line insulation.

Topography: Complex topography, such as mountainous and hilly areas, can pose additional challenges to the installation and maintenance of distribution lines. In these areas, the path of the line needs to be chosen more carefully, and the fixing and support of the line need to be strengthened to prevent damage to the line due to terrain changes.

Plant and animal impacts: Tree growth, animal activities, etc., can also cause damage to power distribution lines. For example, tree branches and leaves may touch the line and cause a short circuit, and animals may bite the line or damage the line equipment. Therefore, it is necessary to regularly trim trees and set up anti-animal bite devices.

3. Maintenance measures

Periodic inspection: Periodically inspect power distribution lines to detect and handle abnormalities in a timely manner. The inspection contents include the appearance of the line, the state of the insulator, and the stability of the pole and tower.

Cleaning and maintenance: Regularly clean weeds, branches and other debris on the line to keep the line smooth. At the same time, the poles, insulators and other equipment should be cleaned and maintained to prevent the influence of external factors on the line.

Maintenance and replacement: Timely maintenance or replacement of aging and damaged equipment to ensure the normal operation of the line. The maintenance and replacement work should be carried out in strict accordance with the operating procedures to ensure the safety and quality of operation.

Troubleshooting: Find and remove faults on the line in time, such as short circuit and broken line. The instrument and equipment are used to detect the fault, determine the fault point and fault type, and take the corresponding fault treatment method.

4. Equipment factor

Aging: Power distribution lines and devices gradually age as the service time increases, resulting in decreased insulation performance and loose connections. Therefore, it is necessary to check and test the lines and devices regularly and replace the aging components in time.

Equipment quality: The quality of equipment directly affects its service life and performance. When purchasing equipment, it is necessary to select products with reliable quality and excellent performance, and install and use them in strict accordance with the operating procedures.

Ensuring the safety of distribution lines is the basic condition to ensure the normal operation of daily work and life. It should be paid more attention to from the government, enterprises and people. Putting the usual maintenance work in the first place and strengthen management and supervision, which not only can save later maintenance costs, but also ensure the safety of people's lives and property.
