Provisions on double power supply in high-rise residential quarters

Provisions on dual power supply in high-rise residential quarters: When the number of floors of civil buildings reaches 10, it is designed according to the second-class power load, that is, it is supplied by two power sources.

General residential quarters draw two power sources from the municipal power grid, one for normal power supply and the other for standby. Residential first-class load: dual power supply with municipal switch station. One power supply in the community is led from the underground garage substation to the equipment in the building, and the other standby power supply is also led from the underground garage substation to the building. If the municipal power outage will not stop both roads, the backup power supply will work.

There is no clear requirement in the national standard that elevators must be equipped with standby power supply. In addition, the cost of dual power supply is high, which often costs millions of yuan, even if it is a self-provided generator, it will cost nearly 100 thousand yuan. So in real life, elevators are generally not equipped with standby power supply. Everyone can only pay attention to check the power outage information in advance as far as possible, and close the elevator in time before the power outage to avoid the accident of the elevator being trapped.
