Brief description of the drawings
Fig. 1 is circuit structure schematic diagram of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in Figure 1：The utility model includes first resistor R1 to the 5th resistance R5, FET VF, triode VT, hair
Optical diode LED, electric capacity C, loudspeaker HTD, battery E and switch S, battery E positive pole simultaneously the first end with second resistance R2,
4th resistance R4 first end, electric capacity C first end connect with loudspeaker HTD first end, and battery E negative pole is with switch S's
First end connects, and switchs S the second end while is connected with triode VT emitter stage and FET VF the first base stage, field effect
Should pipe VF emitter stage be connected with first resistor R1 first end, first resistor R1 the second end is live detection end IN, field effect
Should pipe VF the second base stage simultaneously be connected with second resistance R2 the second end and 3rd resistor R3 first end, 3rd resistor R3's
Second end is connected with triode VT base stage, and triode VT colelctor electrode is simultaneously electric with the negative pole of LED and the 5th
R5 first end connection is hindered, the positive pole of LED is connected with the 4th resistance R4 the second end, and the second of the 5th resistance R5
End is connected with electric capacity C the second end and loudspeaker HTD the second end simultaneously.
Operation principle of the present utility model is as follows：
Detection circuit, when when test side, IN has detected electricity, the alternation magnetic of civil power are formed by FET VF, triode VT
Field produces induced electromotive force in circuit is detected, and goes off the FET VF of conducting, triode VT conductings, light-emitting diodes
Pipe LED is lighted, loudspeaker HTD sounding alarms.During without electricity, the triode VT angle of flow is less than 0.7V and ends triode VT.
The advantages of general principle and principal character of the present utility model and the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, on the premise of the spirit and scope of the utility model is not departed from, the utility model is also
Various changes and modifications are had, these changes and improvements are both fallen within claimed the scope of the utility model.The utility model
Claimed scope is by appended claims and its equivalent thereof.
