At present, UPS arises at the historic moment with the advantage of its low investment, feasibility.UPS can be divided into interchange UPS and direct current UPS by its output form, and it is alternating current output with the cell voltage inversion that interchange UPS needs inverter, and direct current UPS is directly supply load work then.A kind of power supply that can guarantee the normal operation of switch under the civil power powering-off state, and some information of display power supply in real time are such as particular importances that just seems such as output voltage, output current, charging and discharging state, charging currents.

Summary of the invention

At the deficiency that prior art exists, the utility model provides a kind of mine intrinsic safety type intelligence ups power, the problem of switch cisco unity malfunction in the time of can solving municipal power failure under the coal mine.It not only can be applied in general place, also can be used in the inferior place that specific (special) requirements is arranged of coal mine.

In order to achieve the above object, the technical scheme that the utility model is taked is: a kind of mine intrinsic safety type intelligence ups power device, comprise housing and be installed in the interior power circuit of housing, described power circuit comprises input module, AC/DC module, output module, rectification circuit, battery module, diverter switch, display module and control module; Input module connects AC/DC module and rectification circuit respectively, and rectification circuit connects battery module, and battery module connects diverter switch, and the AC/DC module is connected output module respectively with diverter switch, and control module output connects diverter switch and display module respectively.The foregoing circuit device is in an airtight metal or non-metal shell.

Operation principle: when civil power just often, civil power is converted to direct voltage through the AC/DC module with interchange by an input module part, be transferred to output module, powering load, another part is given charging battery module by rectification circuit, and control module one side control its switch makes its disconnection simultaneously, on the other hand data are passed to LCD MODULE, make states such as its display voltage, electric current.When municipal power failure, control module control its switch on the one hand makes its conducting, and this moment, battery module passed through diverter switch, was transferred to output module, and powering load is passed to LCD MODULE to data on the other hand, makes states such as its display voltage, electric current.

The utility model has the advantages that: applicability is strong, and stability is high, and energy is some essential informations of display power supply in real time, the problem of switch cisco unity malfunction in the time of can solving coal down-hole municipal power failure.
