Embodiment
Below be the specific embodiment of the utility model and combine accompanying drawing, the technical scheme of the utility model is done further to describe, but the utility model is not limited to these embodiment.
Like Fig. 1, shown in 2 and 3; Originally the power pack that has protective circuit comprises the power pack housing with inner chamber, and the power pack housing wall is provided with switch 1 and two jacks 2, and the power pack housing is rectangular build; Comprise loam cake 3 and lower cover 4; Form above-mentioned inner chamber between loam cake 3 and the lower cover 4, two jacks 2 are arranged on the upper surface of loam cake 3, and switch 1 is arranged on the lateral wall of loam cake 3.Control circuit board 8, socket main body 9 are installed in the power pack housing inner chamber and can civil power be converted to the dropping equipment of low-voltage, the dropping equipment in the present embodiment is a transformer 10.
This power pack also comprises a plurality of illuminating lamp interfaces that are installed on the power pack housing; Illuminating lamp interface in the present embodiment is a Halogen lamp LED interface 5; Supply main 7 passes the power pack housing and is electrically connected with control circuit board 8; Transformer 10 all is electrically connected with control circuit board 8 with socket main body 9 and socket main body 9 is positioned at jack 2 places; Switch 1 is connected with a plurality of Halogen lamp LED interfaces 5 and is electrically connected with transformer 10 through switch wire 11; This power pack also comprises the temperature sensor 1 that is installed on the supply main 7 that gets in the power pack, is installed in the temperature sensor 2 14 on the switch wire 11 and is installed in the single-chip microcomputer 12 in the inner chamber; Control circuit board 8, temperature sensor 1 and temperature sensor 2 14 all are connected with single-chip microcomputer 12; Temperature sensor 1 and temperature sensor 14 can be respectively to get on the supply main 7 in the power pack with switch wire 11 on temperature information gather and send to single-chip microcomputer 12, single-chip microcomputer 12 can compare the break-make of analyzing and send out according to analysis result control signal control control circuit board 8 according to its temperature information that receives and original initial range value of setting.Alternating interface between man and computer with input/output function also is installed on the power pack surface of shell, and alternating interface between man and computer is electrically connected with single-chip microcomputer 12.Alternating interface between man and computer in the present embodiment comprises keyboard that is used for input temp initial range value and the liquid crystal display screen that is used to show.
In single-chip microcomputer 12, store one group of temperature initial setting value range through keyboard earlier; Comprise two numerical value; One be with enter into power pack in the relevant temperature initial setting value range of supply main 7; When mains supply 6 normal power supplies were given power pack, its temperature one that enters on the supply main 7 in the power pack fixed in this initial setting value range.When the electric current on the supply main that enters into power pack 7 was excessive, the electric current heating was risen supply main 7 temperature, and temperature sensor 1 sends to single-chip microcomputer 12 with the actual temperature information that collects; Single-chip microcomputer 12 compares the temperature of actual acquisition and original setting range value; This moment, the temperature of actual acquisition surpassed the upper limit of setting range value, thereby sent out control signal control control circuit board 8 open circuits, and the socket main body 9 on the power pack all breaks off no power with transformer 10; Its supply main 7 that enters in the power pack breaks off no power; Do not have electric current to pass through, no longer continue heat production, its supply main 7 that enters in the power pack is slowly lowered the temperature; (temperature sensor 1 can be a collecting temperature information in real time when actual temperature that temperature sensor 1 collects is reduced in the setting range value; Also can be collecting temperature information regularly), thus 8 conductings of single-chip microcomputer 12 control control circuit boards let current lead-through, and its socket main body 9 continues operate as normal with transformer 10.Have into the overcurrent power-off protection function and advance electric current and recover the function of switching on automatically, reach intelligent, thereby prevent the operate as normal of the too high warming-up effect power pack of electric current even serious security incident takes place.Another numerical value be with switch wire 11 on the relevant temperature initial setting value range of temperature; This setting range value is that single-chip microcomputer 12 is judged the temperature reduced value relatively that temperature sensor 2 14 is gathered from switch wire 11; Principle is caught up with the identical of face, makes power pack have the overcurrent of going out power-off protection function and go out electric current to recover the function of switching on automatically.When actual temperature that temperature sensor 1 is gathered surpasses on the setting range value in limited time when advancing overcurrent (be civil power), control circuit board 8 open circuits, jack 2 and Halogen lamp LED interface 5 all are disconnected obstructed electric current; The actual temperature of gathering when temperature sensor 1 is normal; And the actual temperature that temperature sensor 2 14 is gathered surpasses on the setting range value in limited time when going out overcurrent (be transformer 10); Conducting between control circuit board 8 disconnections and the transformer 10; Be that Halogen lamp LED interface 5 is disconnected obstructed electric current, and jack 2 still can operate as normal.
Dropping equipment in the present embodiment can also be the LED lamp driver, and corresponding illuminating lamp interface is the LED lamp interface that is used to install the LED lamp.
Illuminating lamp interface in the present embodiment can also be installed in the illuminating lamp interface in other places that need throw light on.When the illuminating lamp interface can be arranged on this power pack housing, evening, darkness can not find jack 2 when plugging appliance plug like this, and people can open switch 1, and the lighting apparatus on the illuminating lamp interface lights, and is convenient to the accurate position that people conveniently find jack 2; When on cabinet or showcase, using; Generally the illuminating lamp interface is installed in top or the top in the showcase in the cabinet so that in the cabinet or the illumination of the thing in the showcase; According to actual conditions the illuminating lamp interface is installed to the place of needs, it is very convenient to throw light on.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from the spirit of the utility model or surmount the defined scope of appended claims.
