Utility model content
Utility model object: the purpose of this utility model is to solve deficiency of the prior art, provides a kind of structure simple, wire line power-on detection device with low cost.
Technical scheme: a kind of wire line power-on detection device described in the utility model, comprise node M, described node M branch road is connected with by triode VT1, the amplifying circuit that triode VT2 and triode VT3 forms, another branch road of described node M is connected with diode VD, the emitter of described triode VT3 is connected with variable resistor RP, described variable resistor RP is connected with triode VT4, described triode VT4 is connected in series with resistance R and light emitting diode L, described light emitting diode L is connected in parallel to loudspeaker D, described light emitting diode L is also connected with electric capacity C parallel with one another and power supply E.
As optimization, described node M is connected with a wire.
As preferably, described conductor length is 2 ~ 5cm.
Beneficial effect: the utility model structure is simple, and reasonable in design, by detecting electric current in wire, can judge the broken position of wire, the conductor cord disconnection position that particularly cannot contact, easy to use, detection efficiency is high.
Accompanying drawing explanation
Fig. 1 is circuit theory diagrams of the present utility model.
Embodiment
A kind of wire line power-on detection device as shown in Figure 1, comprise node M, node M branch road is connected with by triode VT1, the amplifying circuit that triode VT2 and triode VT3 forms, another branch road of node M is connected with diode VD, the emitter of triode VT3 is connected with variable resistor RP, variable resistor RP is connected with triode VT4, triode VT4 is connected in series with resistance R and light emitting diode L, light emitting diode L is connected in parallel to loudspeaker D, light emitting diode L is also connected with electric capacity C parallel with one another and power supply E, wherein node M is connected with a wire, conductor length is 2 ~ 5cm.
Wire in this device is inductor actually, when wire is near charged city's electrical lead, induced voltage is through VD rectification, and the complex pipe be made up of triode VT1 ~ VT3 amplifies, and is added to the base stage of triode VT4, make triode VT4 conducting, light emitting diode and speaker drive sound and light alarm, and when wire is away from city's electrical lead, because of non-inductive voltage triode VT1 ~ VT3 no-output, triode VT4 can not get bias current and by, light emitting diode and loudspeaker are not reported to the police.
