Electrical equipment inspections in high and low-voltage power distribution rooms cannot be overlooked; they are crucial for ensuring the safe operation of electrical equipment. Maintenance of high and low-voltage power distribution room equipment must be stringent, not lenient. There is only an endpoint in electrical safety production, no starting point! The inspection of electrical engineering equipment in high and low-voltage power distribution rooms cannot be neglected; it is a key method for maintaining the safe operation of electrical equipment.

The safety patrol content for high and low voltage power distribution rooms is as follows:

1. Inspected the power supply and distribution system routes, no short-circuit faults, overloads, or operational errors caused power outages in part or large-scale power supply systems.

2. Various practical operation organizations are flexible, with smooth contact, reasonable interlocking of machinery and equipment, and oiling and lubrication provided for the operation organizations.

3. Inspect transmission lines, particularly the insulation at the entry and exit branches of the transmission lines, to ensure it is intact and undamaged.

4. Transformer operation is stable with no excessive noise and temperature rise, natural ventilation equipment is excellent, secondary working voltage of the distribution system (in broad daylight) is 390V, and the transformer's dust removal screw is securely tightened.

5. A variety of circuit breakers feature excellent contact at busbar槽 connections, no overheating conditions, detailed busbar support brackets, and securely tightened busbar slots.

6. Power capacitors are free of bulging and exhibit excellent natural ventilation, with an increase in temperature not exceeding 40℃. Verify that the three-phase current of each power capacitor is balanced.

7. Terminal blocks are neatly arranged and securely tightened, with excellent automotive relay components and agile positioning.

8. Inspect transmission lines, particularly the insulation at the entry and exit branches of the transmission lines for any damage.

The high and low voltage distribution rooms feature excellent lighting fixture cleaning, ample fire equipment, and reasonable strategies to prevent animal intrusion.

The new air system, exhaust system, and central air conditioning equipment in the high and low voltage power distribution room are in perfect condition with no damage, and the temperature does not exceed 35 degrees.

11. Inspected transformer cooling fan operation; transformer cooling fans' temperature control across all stores adjusted to start at 80℃ and stop at 60℃.

12. Complete the relevant records.

Maintenance and Care Content for High and Low Voltage Power Distribution Rooms, Common Issues

Be mindful of regular cleaning and maintenance of machinery and equipment.

Due to the majority of power engineering machinery being installed outdoors, it is essential to increase the cleaning scope during routine maintenance. When cleaning power engineering machinery, it is necessary to select appropriate cleaning chemicals based on the specific technical standards of the machinery and common issues.

2. Implement corrosion prevention strategies to extend the lifespan of machinery and equipment

During the maintenance and repair of low-voltage and high-voltage power distribution rooms, and throughout the entire process of maintaining electrical equipment, corrosion prevention is a crucial task that directly impacts the lifespan of the equipment. Key activities in the corrosion prevention process for electrical equipment include: For exposed electrical conductor connections, apply corrosion prevention by using electrical engineering composite grease directly on the connections to prevent oxidation and ensure reliable operation of the connections.

3. Prevent moisture to ensure the smooth operation of electrical equipment

In high-voltage power distribution rooms, issues such as high humidity and dampness are prevalent. To effectively prevent dampness in these rooms, the following measures should be taken: Firstly, seal the openings of switch cabinets and cable trenches. For the cable trenches in high-voltage power distribution rooms, sealing and waterproofing strategies should be implemented to ensure the isolation of the cable trenches from the interior and exterior. This prevents the entry of water into the cable trenches of the high-voltage room. At the same time, seal the cable penetration in the switch cabinets to avoid the dampness affecting the high-voltage switch equipment.

Establish emergency plans and enhance daily management.

By regularly maintaining and servicing power operation equipment, power companies gain a general understanding of the actual operational status of the equipment. Based on this, hidden or potential faults can be predicted, and targeted emergency plans can be prepared in advance to prevent the spread of adverse effects. At the same time, it is necessary to clearly identify the issues with the electrical lines to facilitate the troubleshooting of wire faults and continuously improve work efficiency.
