Brief description of the drawings
Fig. 1 is structured flowchart of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
The utility model comprises fuel cell module, DC-DC converter, auxiliary battery banks, automatic start-stop unit, relay and D.C. contactor.The control end of described fuel cell module is connected to the output of D.C. contactor after by automatic start-stop unit, and the output of this fuel cell module is connected to load after by DC-DC converter; Described auxiliary battery banks connects the output of load, D.C. contactor and the input of automatic start-stop unit simultaneously.Wherein, the model of described fuel cell module is SXHFC-FEE5KW1, has start and stop controllable function, can carry out on off control to it by signal; The model of described DC-DC converter is ACE254RUW48, can carry out rectification to the output voltage of fuel cell module, and exports 48V voltage to using by electric loading.The effect of described auxiliary battery banks is to power in the time of the firm power-off of civil power temporarily, and after the mains supply comes out or fuel cell module start successfully, auxiliary battery banks is output power no longer.Described automatic start-stop control unit has automatic identification the mains supply comes out or power down mode, automatic start-stop fuel cell module and automatically connects the functions such as the disconnected 54VDC input power from civil power.This automatic start-stop control unit comprises A/D converter and MCU controller, and wherein, the output of A/D converter is connected with the input of MCU controller; The input of described A/D converter is the input of described automatic start-stop unit; The control end of the output connecting fuel battery module of described MCU controller.The utility model also comprises that model is the relay of BS102-5VDC, and its input is connected with the output of described MCU controller, and its output is connected with the control end of described D.C. contactor.The model of described D.C. contactor is BCZ3-50A/01 DC48V, can with relay and the acting in conjunction of MCU controller, simulation civil power powering-off state is to carry out regular Function detection to fuel cell module.
Operation principle of the present utility model is:
While automatically switching to fuel cell back-up source, operation while the utlity model has power-off, automatically regularly detect fuel cell
The functions such as back-up source.In the time of mains failure, automatic start-stop control unit will detect that load power source terminal voltage declines, and then send enabling signal to fuel cell module; In the time of the mains supply comes out, automatic start-stop control unit will send shutdown signal to fuel cell module, recover to be powered by the 54VDC power supply from civil power, thereby realize the fuel cell function of power supply in support.Described fuel cell module is that start and stop are controlled, can carry out on off control to it by a dry contact signal.When under civil power normality electric power thus supplied, on off control unit can also drive D.C. contactor by relay, 54VDC power supply from civil power is connected to disconnected control, thus simulation civil power powering-off state, thus fuel cell backup power system is carried out to Function detection.
The utility model can be identified the mains supply comes out, power down mode, and is provided with 2 configurable values: incoming call threshold value, power failure threshold value, in following explanation, be set to respectively 52V and 49V by this 2 value.
Under normal circumstances, providing power supply by civil power, be converted to 48V DC power supply, is base station power supply, and concrete magnitude of voltage can be set to 54V.In the time there is civil power power-off, powered by 48V auxiliary battery banks, power-off moment battery pack output voltage is 54V, along with battery consumption, voltage drop is to 49V(power failure threshold value) time, MCU controller collects this magnitude of voltage by A/D converter, thereby and to fuel cell module send enabling signal fuel cell module start generating; After fuel cell module generating, DC-DC converter, by automatically adjusting self output voltage values according to the output end voltage value starting before self exporting, increases 1V and exports 50V voltage powering load on 49V basis.When after the mains supply comes out, bus voltage rises to and is greater than 52V(incoming call threshold value) time, MCU controller recognizes this signal again, thereby sends the signal of closing fuel cell module, and fuel cell module will stop generating, transfer backup status to.
In the time of equipment long-time running, need to regularly detect fuel cell back-up source, can send signal by the MCU controller of on off control unit and make relay output end adhesive, thereby drive closed type D.C. contactor, cause major loop to disconnect, thereby simulation mains failure state, carries out Function detection to fuel cell back-up source.If fuel cell back-up source
Fail effectively to enter operating state, load voltage can decline, and in the time being down to 48V, MCU controller breaks down judgement back-up source, and controls D.C. contactor and make its conducting, recover mains-supplied state.If fuel cell back-up source effectively enters operating state, in the time that load voltage drops to 49V, to again go back up to 50V, after maintenance certain hour, MCU controller will judge the normal also detection of end state of back-up source function, control D.C. contactor and make its conducting, recovers mains-supplied state.
The utility model does not relate to partly all prior aries that maybe can adopt same as the prior art to be realized.
