What are the low-pressure rooms and high-pressure rooms in the basement of the hotel for?

1, large and medium-sized hotels require double-circuit power supply, and the load is relatively large, so they should provide 10KV power supply;

2. The hotel will use transformers to reduce the voltage from 10KV to 400V (usually called 380V), but in practice, more than two transformers will be used to meet the requirements of low-voltage dual power supply, and each transformer will provide high voltage of 10KV. In addition, high-voltage double circuits generally need bus coupling, so there must be a 10KV power distribution device, which is the high-voltage power distribution room.

3. Transformers and low-voltage distribution devices are generally installed in the same place, that is, substations (low-voltage distribution is called low-voltage distribution stations);

4. When the building and electricity consumption are small and meet the requirements of power supply management, high and low voltage can also be used in the same place.

You should be talking about a multi-star hotel with a building area of over 10,000 square meters. The work is good. Congratulations.
