The purpose of this utility model is to overcome above-mentioned weak point, provides a kind of financial cost low, power circuit transformer anti-theft alarm easy to install.
The purpose of this utility model can reach like this: (a) power circuit transformer anti-theft alarm, it comprises shell, and be installed in power switch on the shell, drag the line attaching plug, to be the phase line output terminal that drags the line attaching plug link to each other with the phase line input end of relay and the phase line input end of Isolated Shield transformer respectively after a fuse and power switch series connection feature of the present utility model, and the zero line input end that relay zero line input end, Isolated Shield are covered transformer links to each other with dragging line attaching plug zero line output terminal; Two output terminals of Isolated Shield transformer link to each other respectively with two input ends of bridge rectifier circuit; The positive and negative electrode output terminal of bridge rectifier circuit, filtering circuit, mu balanced circuit three prime links to each other respectively successively with the positive and negative electrode input end of back level; The positive and negative electrode output terminal of mu balanced circuit links to each other with the positive and negative electrode of charging accumulator respectively; The positive and negative electrode of charging accumulator links to each other respectively with the positive and negative electrode input end of warning circuit; The parallel circuit that the red light emitting diodes of band current-limiting resistance and loud-speaker are formed is formed warning circuit with often opening of relay after the output switch is in series.
(b) above-mentioned power circuit transformer anti-theft alarm, what it is characterized in that relay often opens an output switch ends pushbutton switch in parallel; Pushbutton switch is installed on the shell.
(c) the described power circuit transformer anti-theft of a, b alarm is characterized in that installing on the shell power light, and power light is a light emitting diode; Light emitting diode and current-limiting resistance are composed in series power indicating circuit, insert the output terminal of mu balanced circuit.
The utlity model has following advantage:
1, internal wiring is simple in structure; Overall volume is little, and is in light weight;
2, during the conversion place to use, move, install easily, need only plug in gets final product;
3, energy consumption is little, long service life.
Description of drawings
Accompanying drawing is the utility model internal wiring circuit diagram.
Led2 is a light emitting diode among the figure, and R3 is a current-limiting resistance, and AN is a pushbutton switch, Led1 is a red light emitting diodes, and R2 is a current-limiting resistance, and KJ is that relay J is often driven the output switch, Y is loudspeaker, and E is a charging accumulator, and C1, C2 are two electric capacity that pi filter is used, D5 is a voltage stabilizing diode, and D1, D2, D3, D4 are the diode of bridge rectifier circuit, and B is the Isolated Shield transformer, J is a relay, and K is a power switch, and FUSE is a fuse, L represents phase line, and N represents zero line.~220V represents (possibility) stolen transformer-supplied circuit 220V AC power.
Embodiment
The utility model is further described below in conjunction with accompanying drawing.Power circuit transformer anti-theft alarm, it comprises shell, and is installed in the power switch K on the shell, drags the line attaching plug.The phase line output terminal that drags the line attaching plug links to each other with the phase line input end of relay J and the phase line input end of Isolated Shield transformer B respectively after a fuse fuse and power switch K series connection, and the zero line input end of relay J zero line input end, Isolated Shield transformer B links to each other with dragging line attaching plug zero line output terminal.Two output terminals of Isolated Shield transformer B link to each other respectively with two input ends of the bridge rectifier circuit that four diode D1, D2, D3, D4 form.Two capacitor C 1, C2 form π shape filtering circuit.Mu balanced circuit is a voltage stabilizing diode D5.The positive and negative electrode output terminal of bridge rectifier circuit, filtering circuit, mu balanced circuit three prime links to each other respectively successively with the positive and negative electrode input end of back level.The positive and negative electrode output terminal of mu balanced circuit links to each other with the positive and negative electrode of recharged battery E respectively.The positive and negative electrode of recharged battery E links to each other respectively with the positive and negative electrode input end of warning circuit; Current-limiting resistance R2 with after red light emitting diodes Led1 connects again with loud-speaker Y be in parallel the parallel circuit formed again with relay J often open the output K switch J composition warning circuit that is in series.
In order to judge that foregoing circuit can operate as normal, can relay J often open an output K switch J two ends pushbutton switch AN in parallel, and be installed on the shell.Press the button switch AN, be equivalent to often opening of relay J and export K switch J closure, the situation the when the utility model that can try sends the sound and light alarm signal.
In order to indicate power supply, the utility model is installed a power light on shell.Power light is light emitting diode Led2; The series circuit that light emitting diode Led2 and current-limiting resistance R3 form inserts the output terminal of mu balanced circuit.The indication information of power light is: when lamp is bright, illustrate that recharged battery E or mu balanced circuit can normal power supplies.When lamp does not work, the neither energy of recharged battery E and mu balanced circuit normal power supply is described, this kind situation seldom may occur.
The utility model financial cost is low, and the high 16cm of whole device, wide 11cm, thick 6.7cm so volume is little, can makes things convenient for the rural power worker in vast isolated area, the easy stolen transformer-supplied district or protect bar and protect line person and put at home and use.And need not to pull strings in addition when using, as long as this practical line attaching plug that drags is inserted in the transformer-supplied district any one on line socket.The utility model is simple, and failure rate is low and reliable, provides technical powerful support for effectively resisting the transformer anti-theft activity.
During the utility model work, recharged battery E is located charged state for a long time.The temporal regularity stolen at transformer mostly is night, but daytime or normal the power failure power switch K by on " OFF " position during use are in charging or alarm condition to avoid recharged battery E always.Then power switch K is pressed on " ON " position between the lights.Power circuit transformer-supplied circuit 220V directly provides power supply to relay J and Isolated Shield transformer B, the low-voltage alternating-current of Isolated Shield transformer B output, after bridge rectifier, the filtering of π shape, voltage stabilizing, wait until direct supply, provide DC voltage to warning circuit.The decompression in case power circuit transformer-supplied circuit transformer is stolen, relay J is often opened output K switch J closure, the red light emitting diodes Led1 of warning circuit lights, loudspeaker Y warnings of sounding a buzzer simultaneously is till power circuit recovery normal power supply and then the utility model are got back to original duty again.
