Abstract

The invention discloses a low-voltage DC power supply system for an apartment dormitory. The low-voltage DC power supply system comprises a total distribution box and a plurality of sub distribution electric boxes, the total distribution box is respectively distributed to the plurality of sub distribution electric boxes through a transformer, the plurality of sub distribution electric boxes are respectively provided with three circuits, each circuit is used for powering 36V equipment of one dormitory, is out from the sub distribution electric boxes and connected in parallel to a 36V electric fan, a 36V energy-saving lamp and a 36V power supply socket. The low-voltage DC power supply system for an apartment dormitory adopts a transformer capable of transforming 380V to 36V to reduce the ACsupply voltage of the distribution line to a DC safety voltage of 36V, thereby avoiding the risk of fire caused by the private connection and the use of high-power electrical appliances in the dormitory environment and greatly reducing the potential safety hazard of the dormitory.

Description

technical field [0001] The invention relates to a power supply system, in particular to a low-voltage direct current power supply system suitable for construction workers' dormitories. Background technique [0002] At present, most construction companies only use 36V DC power supply for lighting in the dormitories of construction workers. The dormitories are equipped with 220V power sockets, and 220V power is introduced into the construction dormitories of workers. Electrical appliances pose a great potential safety hazard to the safety of workers' dormitories. With the increase of construction projects, the country pays more and more attention to safety. In response to the above problems, some companies in the market have developed and produced mobile phone chargers using 36V DC power supply systems, 36V energy-saving lamps, 36V electric fans, and 36V safety-type Flame retardant electric mattresses, so that workers' dormitories can be better implemented with a full 36V DC ...
