Description
Technical field
The utility model relates to a kind of indoor DC power-supply system.
Background technology
Existing indoor power supply all adopts common 220V mains supply, still, in the practical application, has problems; At first, because the employing of indoor multiple adapter like the cap part of charger for mobile phone, electricity-saving lamp, becomes in the process of direct current in interchange; The damage of accumulative total is bigger, and energy-saving effect is bad, in addition, owing to generally adopt the AC power of 220V; Therefore, easy initiation fire or electric shock accidents, fail safe is not high.
The utility model content
The utility model technical problem to be solved provides a kind of indoor DC power-supply system, and this indoor DC power-supply system is safe, and energy-saving effect is good.
The technical solution of utility model is following:
A kind of indoor DC power-supply system comprises transformer, rectifier and direct current supply interface; Transformer is a step-down transformer, the former edge joint mains ac power supply of transformer, and the secondary of transformer connects the direct current supply interface through rectifier.
Described direct current supply interface is USB interface, socket or lamp socket.
Described indoor DC power-supply system also comprises battery and charging circuit; The DC side of rectifier or mains ac power supply join through charging circuit and battery, and the output of battery links to each other with the direct current supply interface.
Described rectifier is half-wave rectifier or bridge rectifier.
The secondary of described transformer has a plurality of taps, and described rectifier and direct current supply interface are a plurality of; The tap of each transformer, rectifier and direct current supply interface form one group of direct current supply branch road, and in each group direct current supply branch road, the tap of transformer links to each other with the direct current supply interface through rectifier.
Described transformer, rectifier and direct current supply interface are a plurality of; The former limit parallel connection of a plurality of transformers; Each transformer, rectifier and direct current supply interface form one group of direct current supply branch road, in each group direct current supply branch road, transformer, link to each other with the direct current supply interface through rectifier.
Step-down and rectification module (like transformer and rectifier etc.) are installed in the distribution box, connect up in addition and installation direct current supply interface again.
Beneficial effect:
The indoor DC power-supply system of the utility model; Convert the AC power of 220V to low-voltage dc power supply; Direct preset various low-tension supplies of output, purpose are to reduce the secondary loss that electronic product such as charger for mobile phone, notebook computer charger, electricity-saving lamp (cap part) etc. are caused, and once cutting down the consumption of energy through disposable step-down and rectification provides power supply for a plurality of electronic products; Improve the electric energy service efficiency, practiced thrift the energy; Simultaneously, also avoid the 220V civil power that the hidden danger of electric shock and fire takes place in actual application.
In addition, the harmful effect that the section has a power failure and brings can be effectively resisted in the design of battery and charging circuit, ensures the mains lighting supply supply, is about to battery and uses as emergency power supply.
The utility model adopts low tension wire, socket, and lamp socket replaces traditional copper cash, socket and lamp socket, reduces line material consumption and expense with low-voltage lighting system.
