DC power supply in the process of operation, if the power supply is insufficient or unable to continue the operation of the need to stop the use of the plant for plant and residential electricity.
Power consumption by factories accounts for a large proportion of China's total electricity consumption, which is very high, so it is necessary to use a DC power supply. Large machinery operations in factories consume a lot of electricity, and dc power is needed to supply the necessary power for this machinery.
The power used in daily life comes from the state grid, which in turn transmits power to various places. As the residential electricity consumption is between 0~220V, the dc power supply and the distributed power supply are combined to divide our electricity to reach the power area that our residential users can bear.
DC power in the factory and the difference between residential demand
