High and low voltage power distribution room power engineering equipment inspection cannot be ignored, it is a key way to maintain the safe operation of electrical equipment. The equipment in the high and low voltage power distribution room is strictly maintained but not lenient. In the work of electric safety production, there is only the terminal station and no starting point! The inspection of electric power engineering equipment in the high and low voltage power distribution room cannot be ignored, and it is a key way to maintain the safe operation of electrical equipment.

High and low voltage power distribution room safety inspection content is as follows:

1. Check the routes of the power supply and distribution system, and there is no short-circuit fault, load or operation error tripping causing partial or large-scale power supply system interruption.

2. A variety of practical operations have flexible organization, excellent touch, reasonable mechanical equipment interlocking equipment, and actual operation organization to lubricate the oil.

3. Inspect the transmission line, especially whether the insulation layer at the branch pipe of the transmission line is intact.

4. The sound of the transformer is stable, the temperature rise does not exceed the requirements, the natural ventilation equipment is excellent, the secondary working voltage of the power distribution system (in broad daylight) is 390V, and the ash removal screw of the transformer is tightened.

5. Various circuit breakers, excellent contact of busbar connectors, no over-temperature conditions, detailed busbar support frames, and busbars tightened.

6. ​​The power capacitor has no bulging condition, good natural ventilation, and the temperature rise does not exceed 40℃; check whether the three-phase current of each power capacitor is balanced.

7. The wiring terminal row is clear and appropriate, tightening is reliable, the characteristics of automotive relay components are excellent, and the posture is flexible;

8. Inspect the transmission line, especially whether the insulation layer at the branch pipes of the transmission line is intact.

9. The high and low voltage power distribution room has excellent cleaning and lighting fixtures, sufficient and detailed fire-fighting equipment, and reasonable countermeasures to avoid animal intrusion.

10. The fresh air system, exhaust system, and central air conditioning equipment of the high and low voltage power distribution room are intact, and the temperature does not exceed 35 degrees.

11. Check that the cooling fan of the transformer works well, and the temperature control of the cooling fan of the transformer is adjusted to 80℃ to start and 60℃ to terminate.

12. Fill in the relevant records.

High and low voltage power distribution room maintenance content and common problems

The company has noticed that the electrical equipment of the processing plant is usually maintained, but has it fully considered the maintenance of the high and low voltage power distribution room of the power supply system of the electrical equipment? Many companies usually do not fully consider the equipment of the high and low voltage power distribution room. Maintenance problems, which in turn lead to power engineering problems.

1. Pay attention to the daily cleaning of machinery and equipment

Because most of the electrical engineering operation machinery and equipment are installed outdoors, according to this, in daily maintenance and maintenance, the cleaning range of machinery and equipment must be increased. To clean up the operation machinery and equipment of electric power projects, it is necessary to select effective and appropriate chemicals for cleaning according to the technical standards of the actual machinery and equipment and common problems.

2. Apply anti-corrosion measures to increase the use time of equipment

In the whole process of maintenance and maintenance of electrical equipment in the high and low voltage power distribution room, the anti-corrosion work is very important, and it also has immediate hazards to the service life of electrical equipment. In the anti-corrosion work of electrical equipment, the main content is as follows: for the exposed electrical conductor connectors, anti-corrosion is provided, and the power engineering compound grease can be used to wipe the connectors immediately to prevent air oxidation of the connectors and ensure that the connectors are reliable in application. Spectrum.

3. Avoid moisture and ensure the good operation of electrical equipment

In the high-voltage power distribution room, there are many problems such as high humidity and heavy moisture. In order to prevent moisture in the high-voltage power distribution room, the following measures should be taken: One is to block the switch cabinet holes and cable trenches. The cable trenches should be blocked and waterproof measures to ensure that the cable trenches in the high-voltage power distribution room are isolated from the inside and outside, and to avoid the inflow of water in the cable trenches in the high-voltage room. At the same time, plug the cable perforations of the power distribution cabinet to prevent the cable moisture from affecting the switchgear in the high-voltage room.

4. Develop emergency plans and enhance daily management

Through daily maintenance and maintenance of power operating equipment, power companies have a general understanding of the actual operating conditions of the equipment. Based on this, they can predict hidden or possible failures of the equipment and formulate targeted emergency response in advance. Plan to avoid the expansion of bad influence. At the same time, it is necessary to clearly point out the problem of the electrical wiring, to provide convenience for troubleshooting the electrical wiring, and to continuously improve work efficiency.
