Abstract
The utility model discloses an emergency plug board, which belongs to the technical field of household appliances. The emergency plug board mainly comprises a transformer, a storage battery, a rectifier, two plug boards, a plug, a direct current switch and an alternating current switch. The emergency plug board has the advantages that the price is low, the use is convenient, and the emergency plug board can provide power for small household appliances during power cut. The emergency plug board can also be used after inverting direct current power into alternating current power through an inverter.
Description
Technical field
The utility model relates to a kind of emergent wiring board, belongs to the living electric apparatus technical field.
Background technology
Electrical equipment needs the wiring board energized just can use, because the supply of electric power of China is relatively more nervous, and the puzzlement that many areas in city and rural area are often had a power failure, one runs into power failure, and any electrical equipment all can not use, and brings great inconvenience for people's life.
The utility model content
The purpose of this utility model is to provide a kind of emergent wiring board that the power supply use can both be provided for small domestic appliance under the situation of power supply or power failure.
To achieve these goals, the utility model provides following technical scheme:
A kind of emergent wiring board, comprise transformer 2, storage battery 3, rectifier 5, wiring board 6, plug 4, switch 1 electric elements such as grade, each electric elements is fixed on the fixed head and by lead and connects, plug 4 connects transformer 2 by lead, the low-voltage alternating-current output termination rectifier 5 of transformer 2, rectifier 5 connects storage battery 3, storage battery 3 connects wiring board 6, be connected with switch 1 between storage battery 3 and the wiring board 6, plug 4 is connected AC power, and AC current flows into rectifier 5 after transformer 2 step-downs, the low-voltage DC input storage battery of exporting after the rectification 3, for storage battery 3 chargings, equal its back electromotive force ∑ until storage battery 3 current potentials, stop charging; Storage battery 3 charging is pulled up plug 4 after finishing back or power failure, and Closing Switch 1 can use wiring board 6 to provide DC power supply as small household appliances.
Emergent wiring board of the present utility model can also be an alternating current with dc inverter, for household electrical appliances provide power supply at storage battery 3 back series connection one inverter 7.
Compared with prior art, the beneficial effects of the utility model: the utility model mainly is made up of transformer, storage battery, rectifier, two wiring boards, plug, direct current switch, alternating current switches, the utility model is cheap, easy to use, still can be small household appliances during power failure power supply is provided.The utility model can be to use after the AC power with the DC power supply inversion by inverter also.
