Abstract
The invention discloses a dual-power-supply power supply system and relates to the technical field of power supply. The dual-power-supply power supply system comprises an incoming line panel, a capacitance compensation panel and a feeder panel, wherein a dual-power-supply switching device is arranged in the incoming line panel, one incoming line end of the dual-power-supply switching device is connected with a mains supply, the other incoming line end of the dual-power-supply switching device is connected with a power generator, and the outgoing line end of the dual-power-supply switching device is connected with the capacitance compensation panel and the feeder panel. The problem that unnecessary loss is caused when an existing business building or office building encounters power supply cut-off of the mains supply can be solved.
Description
Technical field
The present invention relates to power supply technique field; Especially a kind of electric power system that can carry out reliable switching between two-way power supply.
Background technology
Development along with society, electric power is more and more obvious to the importance of all trades and professions, in some office buildings or office building, people are typically all and handle official business with computer, and these occasions are be powered by civil power mostly, once civil power is stopped power supply, and the data in computer are come and preserve, it will cause unnecessary loss.
Summary of the invention
It is an object of the invention to provide a kind of dual power supply system, it can solve existing office building or office building runs into civil power and stops power supply the problem causing unnecessary loss.
In order to solve the problems referred to above, the technical solution used in the present invention is: this dual power supply system, including inlet wire screen, capacitance compensation screen and feed panel, it is provided with double-power supply switching device in described inlet wire screen, one end of incoming cables of described double-power supply switching device electrically connects with city, its another end of incoming cables is connected with electromotor, and the leading-out terminal of described double-power supply switching device is connected with described capacitance compensation screen and feed panel.
In technique scheme, more specifically scheme is it may also is that described double-power supply switching device includes controller and two choppers with motor-operating mechanism, being connected to mechanical interlock mechanism between two described choppers, two described choppers all electrically connect with described controller.
Further: described controller is single-chip microcomputer.
Owing to have employed technique scheme, the present invention is compared with prior art, have the beneficial effect that owing to the present invention is provided with double-power supply switching device, adopt civil power and electromotor dual power supply, when civil power is stopped power supply, double-power supply switching device can be switched to electromotor in time, electromotor provide power supply, reduces the risk of unnecessary loss.
Accompanying drawing explanation
Fig. 1 is the block diagram of the present invention.
Fig. 2 is the block diagram of the double-power supply switching device of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described:
Dual power supply system shown in Fig. 1, including inlet wire screen 1, capacitance compensation screen 2 and feed panel 3, double-power supply switching device 1-1 it is provided with in inlet wire screen 1, one end of incoming cables of double-power supply switching device 1-1 electrically connects with city, its another end of incoming cables is connected with electromotor, and the leading-out terminal of double-power supply switching device 1-1 is connected with capacitance compensation screen 2 and feed panel 3. Double-power supply switching device 1-1(Fig. 2) include controller 1-1-1 and two chopper 1-1-2 with motor-operating mechanism, it is connected to mechanical interlock mechanism between two chopper 1-1-2, two chopper 1-1-2 all electrically connect with controller 1-1-1.In the present embodiment, controller 1-1-1 is single-chip microcomputer.
Under normal circumstances, close the chopper 1-1-2 being connected with city, by mains-supplied, when civil power has fault outage, controller 1-1-1 detects do not have civil power, and after separated in time, double-power supply switching device 1-1 disconnects the chopper 1-1-2 electrically connected with city, close the chopper 1-1-2 being connected with electromotor simultaneously, by generator powered; When controller 1-1-1 detects that city power recovery powers, controller 1-1-1 disconnects the chopper 1-1-2 being connected with electromotor, and close the chopper 1-1-2 electrically connected with city. Owing to being provided with mechanical interlock mechanism between two chopper 1-1-2, so two chopper 1-1-2 can only be one closes a floodgate that another disconnects, do not result in civil power and situation that electromotor is powered simultaneously occurs.
