Description

technical field [0001] The invention relates to a power supply pick-up device, in particular to a dual-power switching power supply pick-up device and an operating method thereof, belonging to the field of electric switches. Background technique [0002] With the development of social economy and the improvement of people's living standards, users have higher and higher requirements for the reliability and continuity of power supply. Power failure will cause huge economic losses and serious social impact; existing low-voltage power distribution cabinets are often It is powered by a single power supply. In case of extreme bad weather or failure of components in the power grid distribution cabinet, it will cause a large-scale power outage; and only a single power supply is not conducive to the maintenance of the power grid and power distribution cabinet. When the cabinet needs periodic maintenance, it will also cause a power outage at the load end; the inherent defects of the ...
