Rural lighting electrical ready board flooded self rescue: emergency measures for power outage, drainage, and inspection

When the rural lighting electrical ready board is flooded, the following emergency measures can be taken for self rescue: power outage, drainage, and inspection. The specific operations are as follows:

power failure:

Immediately cut off the main power supply: In order to prevent short circuits from causing fires or electric shock accidents, power outage measures should be taken as soon as possible, the main power supply of the electrical ready board should be cut off, and a dedicated person should be arranged to guard it.

Use insulated tools for operation: When cutting off power, do not operate directly with your hands. Use insulated rods or dry wood, and wear insulated gloves. This is because cutting off power after being submerged in water may generate a huge arc, which can easily lead to electric shock accidents.

Drainage:

Organize manpower and material resources for drainage: Quickly organize sufficient manpower and material resources, use tools such as water buckets and pumps, and drain the accumulated water around the electrical ready board as soon as possible.

Take good safety precautions: Personnel entering and leaving the electrical ready board area must wear insulated shoes and gloves, operate with insulated rods, disconnect operating equipment in the order of emergency knife switches, and report to unit leaders or owners in a timely manner. During the emergency rescue process, special attention should be paid to the safety hazards of equipment and personnel, and personnel entering and exiting should be controlled. The external door of the equipment should not be opened arbitrarily, and signs should be hung and safety measures should be taken.

Check:

Comprehensive inspection of equipment: After draining the electrical ready board, do not rush to restore equipment operation. It is necessary to conduct a comprehensive inspection of the electrical ready board first, including whether the equipment, cables, etc. are damaged. Clean up the accumulated water, sludge and other debris inside the electrical ready board, and keep the box clean and dry.

Conduct insulation testing: Arrange professional technicians to inspect the equipment inside the electrical ready board, especially for key equipment such as circuit breakers and wires. Use a 2500V megohmmeter for insulation testing to ensure humidity is ≤ 70%. Only after detecting that there are no short circuit faults or hidden dangers, can the closing and power transmission operation be carried out.

Blow dry each component one by one: If water enters the electrical ready board, use a hot air blower to blow dry each circuit breaker, circuit, and other component inside the box one by one. After ensuring that all components are dried, turn on the power and close each switch one by one for testing to see if the switch is damaged.
