How to calculate the load for fire fighting electricity. The use of electricity for fire fighting has a great effect on the safety of people's livelihood. How to calculate this load is of great significance. Let's take a look at how to calculate it.
Q: How to calculate the fire protection load in a building fire situation?
Answer: The fire in a building may occur when normal commercial power is supplied, or it may occur when a backup power source such as a diesel generator is used.
In theory, generally speaking, the fire load of a building should be based on the total electricity load of all fire-fighting elevators and fire emergency lighting of the entire construction project, plus the fire load required for the fire protection zone where the fire fighting equipment has the highest electricity consumption. (Including fire pumps, smoke prevention facilities, etc.) as the load of fire-fighting electrical equipment in the event of a fire.
Relatively small single buildings can directly add all the fire load in a simplified calculation, with a coefficient of one.
Buildings powered by one or two transformers should all be regarded as having a fire when a transformer works normally. The calculation load of fire-fighting equipment plus the non-fire-fighting load that has not been removed due to a fire is taken as the total calculation under fire conditions. The load is used to calculate the load to verify the transformer's overload capacity.
