How to use the ring main unit safely?

The ring main unit is a high-voltage switchgear for power transmission, which is widely used in many large and medium-sized engineering buildings and residential quarters.

What are the common problems in the safe use of the ring main unit?

1. Cable management and maintenance methods should be appropriate. Because the cable can be used for a variety of purposes, it is necessary to make adequate preparations in advance during the construction operation, and to add relevant signs to remind in special cases.

2. During the assembly operation of the ring main unit, the safety of the construction quality must be guaranteed to avoid potential safety hazards.

3. Power distribution equipment is easily damaged by lightning strikes, and all cases of mechanical equipment damage caused by lightning strikes are related. Therefore, zinc oxide high-voltage arresters and scientific and reasonable grounding protection must be installed to prevent the ring main unit from being damaged by lightning strikes.

4. Since the ring main unit is used for high working voltage, it is necessary to ensure that a short circuit or leakage event occurs, and corresponding protective measures should be taken to prevent non-related personnel and small animals from entering.

5. After the ring main unit is successfully assembled, the management method should be improved. Fully consider all aspects of the accident, and complete the inspection and maintenance tasks of the ring main unit on time.

6. Regular maintenance and overhaul of ring main unit spare parts. If it is worn or damaged, it should be discontinued and repaired immediately.
