Which electricity consumption of a 33-story residential building is the first-class load? Which electricity consumption is the secondary load? What is the electricity consumption of the tertiary load? What are the requirements for power supply reliability? The first-class load is: as long as it is fire-fighting load, it includes fire-fighting and security control room, fire elevator, fire alarm, fire pump, fire smoke exhaust system, fire emergency lighting, evacuation indication sign, fire shutter, etc.

The secondary loads are: passenger elevator, domestic water pump, stairs and main passage lighting. In practice, passenger elevators are usually provided with the main load.

The rest are three-level loads.

The primary load should be powered by two power supplies, so that when one power supply fails, the other power supply will not be damaged at the same time. It can be two high-voltage power supplies, or the second power supply can supply power to the diesel generator, and the second power supply with small load can also supply power to the battery.

When the power transformer fails or the common line fails, the secondary load should not interrupt the power supply (or restore the power supply quickly after the interruption). When the load is small or the regional power supply conditions are difficult, it can be supplied by a dedicated line of 6kv or above.

There are no special requirements for the power supply of the tertiary load.
