Power facility maintenance project

Power facility maintenance project is a complex and important field of work, which aims to ensure the safe and stable operation of power facilities and improve the reliability and efficiency of power supply. The following is a detailed overview of power facility maintenance projects:

1. Maintenance content

Power facility maintenance projects usually include the following aspects:

Equipment inspection and testing:

Check regularly whether the instrument switch, signal operation, and fuse device temperature in the power distribution equipment are normal.

Measure the specific value of current operation in the power supply system and check whether it is within the rated allowable value in the line operating environment.

Check the lightning protection equipment and measure the resistance effect to ensure that the lightning protection effect is good.

Check whether the screws at each joint position in the equipment are loose, whether there is corrosion, and check the operation of each instrument in the equipment.

Cleaning and maintenance:

Periodically clean the device, including measuring terminals, cables, and cables, to prevent dust and dirt from accumulating and causing device faults.

Perform special maintenance on important equipment such as the high-frequency switching DC power supply cabinet to ensure that it provides stable DC power to the instruments and lighting in the breaker opening and closing and secondary circuit in the high voltage main control cabinet.

Mutual inductance device maintenance:

As a transformer, it is necessary to check its operating status regularly to ensure that it can effectively protect the instrument lamp device, isolate secondary equipment and high voltage, and ensure the safety of construction personnel.

Preventive maintenance:

According to the use of equipment and manufacturer's recommendations, develop preventive maintenance plan, regular maintenance of equipment and replacement of wearing parts, in order to reduce the occurrence of sudden failures.

Emergency response:

Establish an emergency response mechanism to quickly respond and deal with sudden failures to ensure the continuity and stability of power supply.

2. Maintenance cycle

The cycle of a power facility maintenance project varies according to the type of equipment, its use, and its importance. Generally speaking, it can be divided into the following two categories:

Monthly maintenance items:

Including routine work such as daily inspection, cleaning and maintenance to ensure that the equipment is in good working condition.

Annual maintenance items:

More comprehensive inspection and testing of the equipment, including lightning protection effect inspection, resistance measurement, joint screw fastening, etc., as well as necessary maintenance and replacement work.

Three, maintenance methods

Power facility maintenance projects can be carried out in a variety of ways, including:

Independent maintenance:

The owner or operator of the power facility shall organize a professional team for maintenance.

Outsourced Maintenance:

Outsource the maintenance of power facilities to a professional maintenance company or team. In this way, external resources can be fully utilized to improve maintenance efficiency and quality.

4. Precautions

When performing power facility maintenance projects, pay attention to the following aspects:

Safety first:

Ensure that maintenance personnel have appropriate qualifications and skills, and comply with safety operation rules to prevent safety accidents.

Well planned:

Make detailed maintenance plans and solutions, and determine the maintenance content, frequency, and mode to ensure orderly maintenance.

Complete record:

Record the maintenance process in detail, including inspection results, maintenance contents, and replacement parts, for follow-up tracking and analysis.

Training and Education:

Regular training and education for maintenance personnel to improve their professional skills and safety awareness.
