Embodiment
DSP described in the utility model (Digital Signal Processing) is meant Digital Signal Processing, below in conjunction with accompanying drawing, specifies the utility model.
See also Fig. 1, it is a kind of novel digital EPS fire-fighting emergency power supply Organization Chart based on DSP of the utility model embodiment.It comprises that mains electricity input end 11, charged pool patrol and examine digital charge module 12, batteries 13, inverter 14, diverter switch 15 and controller 16.Charged pool is patrolled and examined digital charge module 12 and is linked to each other with mains electricity input end 11.Batteries 13 is patrolled and examined digital charge module 12 with charged pool and is linked to each other.Inverter 14 links to each other with batteries 13.Diverter switch 15 links to each other with inverter 14, mains electricity input end 11, and is connected to load equipment, is used for the power supply source of load equipment is switched between mains electricity input end 11 and inverter 14.Controller 16 is patrolled and examined digital charge module 12, batteries 13 and inverter 14 with mains electricity input end 11, charged pool respectively and is linked to each other.
When civil power just often, diverter switch 15 is the path conducting between load equipment and the mains electricity input end 11, and being connected between disconnecting consumers equipment and the inverter 14, powered to important load by civil power this moment.Simultaneously, the alternating current of mains electricity input end 11 is patrolled and examined digital charge module 12 by charged pool and is converted to direct current, and batteries 12 is charged.
When mains-supplied is interrupted or line voltage when transfiniting (± 15% or ± 20% specified input voltage), the path that diverter switch 15 is communicated with between load equipments and the inverter 14, and being connected between disconnecting consumers equipment and the mains electricity input end 11.At this moment, controller 16 control inverters 14 start inversion immediately, and the direct current of batteries 13 is converted to alternating current, and are the load equipment power supply.
When line voltage recovers operate as normal, controller 16 sends signal inverter 14 is carried out automatic power-off operation, simultaneously diverter switch 15 will be communicated with being connected between load equipment and the mains electricity input end 11 once more, and being connected between disconnecting consumers equipment and the inverter 14.
