Distribution room inspection content and distribution room maintenance notes

Inspection of power engineering equipment in high and low voltage distribution room can not be ignored, it is the key way to maintain the safe operation of electrical equipment. High and low voltage power distribution room equipment maintenance to strict, loss to wide. Power safety production work only terminal no starting point! The inspection of electrical engineering equipment in high and low voltage distribution room can not be ignored and is the key way to maintain the safe operation of electrical equipment.

Safety inspection for high and low voltage power distribution room is as follows:

1. Check the route of power supply and distribution system, and ensure that there is no short-circuit fault, load or operation error resulting in partial or large-scale power supply system interruption.

2, a variety of practical operation organization flexible, good touch, mechanical equipment interlock equipment is reasonable, the actual operation organization to oil.

3, check the transmission line, is the transmission line in and out of the branch pipe insulation layer is intact.

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

5, all kinds of circuit breakers, busbar connection head good contact, no overtemperature condition, busbar support frame details, busbar tightening.

6, power capacitor without bulging condition, good natural ventilation, temperature rise is not more than 40℃; Check that the three - phase current of each power capacitor is balanced.

7, the wiring terminal row is clear and appropriate, tighten reliably, automobile relay components have excellent characteristics and easy posture;

8, check the transmission line, is the transmission line in and out of the branch pipe insulation layer is intact.

9. High and low voltage power distribution room cleaning lighting lamps and lanterns are excellent, fire protection equipment is abundant and detailed, and the countermeasures to avoid animal invasion are reasonable.

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

11. Check the excellent operation of the cooling fan of the transformer. The temperature of the cooling fan of the transformer is adjusted to 80℃ for starting and ending at 60℃ for each store.

12. Fill out the relevant records.

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

1. Pay attention to the cleaning of machinery and equipment

Because the vast majority of power engineering operation machinery and equipment are installed outdoors, according to this, in daily maintenance and maintenance, it is necessary to increase the cleaning range of machinery and equipment. Cleaning power engineering operation machinery and equipment, according to the actual machinery and equipment technical standards and common problems, the selection of effective and appropriate chemicals for cleaning.

2. Apply anti-corrosion countermeasures to increase the service time of machines and equipment

High and low voltage distribution room maintenance and maintenance of electrical equipment in the whole process, corrosion prevention work, is very key, the use of electrical equipment also has immediate harm. In the anti-corrosion work of electrical equipment, the main content is as follows: for the exposed electric conductor connection head, give anti-corrosion, can choose the power engineering compound grease immediately wipe, prevent air oxidation connection head, ensure that the connection head application is reliable.

3. Avoid humidity and ensure that the power equipment runs properly

In the high voltage transformer room, with the big humidity, moisture, and many other problems, to do a good job in high voltage transformer room moistureproof shall take the following measures: one is seal and plug the hole of switchgear and in cable trench, the high voltage transformer room in cable trench, shall be sealed and waterproof measures, to ensure that the internal and external isolation high-voltage transformer room in cable trench, avoid water inflow in the high pressure chamber in cable trench. At the same time, plug the cable perforation of the distribution cabinet to avoid cable moisture affecting the switchgear of the high voltage chamber.

4. Develop emergency plans and enhance daily management

Through daily maintenance and maintenance of power operation equipment, power enterprises have a general understanding of the actual operation of equipment. Based on this, hidden or possible faults of equipment can be predicted, and targeted emergency plans can be made in advance to avoid the expansion of bad effects. At the same time, it is necessary to clearly point out the problem of the electrical line, provide convenience for troubleshooting the electrical line fault, and constantly improve the work efficiency.
