Safety protection tips for transformers during and after heavy rain.

2024-06-19

During this period, the country has generally welcomed high temperatures and rainy weather, with heavy rainstorms occurring widely. The impact of stormy weather on electrical equipment is significant, especially regarding the water accumulation during and after the storm, which can be electrified. If someone touches this electricity, they could be electrocuted, leading to serious situations. What should be done during the storm and after the water accumulation? Here are some relevant measures and methods for reference.
1. Safety precautions during heavy rain

Strengthen inspections: Before the storm arrives, inspections should be conducted in advance around transformers and their surrounding environment to ensure there is no water accumulation or debris around the transformer, and to check whether the lightning protection and waterproof facilities of the transformer are intact.
Waterproof measures: For transformers installed outdoors, ensure that the waterproof measures on the top and sides are effective to prevent rainwater from directly washing or seeping into the transformer, which could lead to electrical failures or short circuits.
Lightning protection: Heavy rain is often accompanied by lightning; therefore, the lightning protection facilities of transformers must be intact and effective. Regularly check the status of lightning rods, surge protectors, and other lightning protection equipment to ensure they can function properly.
Emergency preparedness: Before the storm arrives, an emergency plan should be developed, and emergency repair equipment and materials should be prepared to respond to possible emergencies.

2. Precautions after heavy rain

Timely inspections: After the storm, immediate inspections of transformers should be conducted to check for any damage and changes in the surrounding environment. Pay special attention to checking whether the insulation performance and waterproof measures of the transformer have been compromised.
Clear water accumulation: Water accumulation around transformers should be cleared promptly to avoid corrosion or short circuits caused by standing water. At the same time, safety precautions should be taken during the clearing process to prevent electric shock accidents.
Check equipment status: After heavy rain, a comprehensive inspection of transformers and their auxiliary equipment should be conducted, including key parameters such as oil temperature, oil level, and winding temperature, to ensure that the equipment is in normal condition.
Repair damaged facilities: Facilities such as lightning protection and waterproofing that were damaged during heavy rain should be repaired or replaced promptly to ensure the safe and stable operation of transformers.
Summary and improvement: After heavy rain, a summary analysis of this incident should be conducted to identify existing problems and shortcomings, propose improvement measures to enhance future response capabilities for similar events.
