Accompanying drawing explanation
Fig. 1 is alarm for high voltage circuit diagram.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.Following examples are only for the technical solution of the utility model is more clearly described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, alarm for high voltage circuit of the present utility model is comprised of exploring electrode A, four tones of standard Chinese pronunciation integrated alarm circuit IC, field effect transistor BG1, transistor BG2, BG3, step-up transformer T, piezoelectric ceramic piece HTD, 3V power supply etc.Electric routing switch K controls break-make.
Exploring electrode A is single line footpath 1mm, is about the sub-thread hard plastic electric wire of 10cm, and its one end is connected with the grid of field effect transistor BG1, and the other end is rolled into ringlet, for surveying high pressure object.
The drain electrode of field effect transistor BG1 is connected with the base stage of transistor BG2, and the source electrode of field effect transistor BG1 is connected with power cathode.The emitter of transistor BG2 is connected with power cathode through capacitor C, and the emitter of transistor BG2 is connected to four tones of standard Chinese pronunciation integrated alarm circuit IC for its power supply simultaneously.The collector of transistor BG2 is connected with positive source through K switch.The music alarm signal that four tones of standard Chinese pronunciation integrated alarm circuit IC sends amplifies through transistor BG3, and the collector of transistor BG3 and positive source are connected respectively to the primary coil of step-up transformer T, and the secondary coil of step-up transformer T is connected with the two ends of piezoelectric ceramic piece HTD.
When exploring electrode A is during away from high pressure object, drain electrode, the resistance between source electrode of field effect transistor BG1 are less, respective transistor BG2 because of base potential compared with low in cut-off state, four tones of standard Chinese pronunciation integrated alarm circuit IC does not work because of power supply access failure, corresponding piezoelectric ceramic piece HTD is sounding not.When exploring electrode A approaches high pressure object, the upper induction field signal of exploring electrode A, the now drain electrode of field effect transistor BG1, the resistance between source electrode become large, and transistor BG2 is because of base potential raising conducting, and corresponding four tones of standard Chinese pronunciation integrated alarm circuit IC sends music alarm signal because switching on power.This signal amplifies by the step-up transformer T moving piezoelectric ceramic piece HTD of pusher that boosts and sends chimes of doom through transistor BG3.
Four tones of standard Chinese pronunciation integrated alarm circuit IC can select KD-9561 or CW9561, can select as the case may be the corresponding music alarm sound of four tones of standard Chinese pronunciation integrated circuit.
The common contact of the base stage of the drain electrode of field effect transistor BG1 and transistor BG2 is connected to the positive pole of power supply through a resistance R 1.This circuit, when approaching High Level AC Voltage, will send the chimes of doom of modified tone, and the resistance R in regulating circuit 1 can change alarm distance.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvement and distortion, these improvement and distortion also should be considered as protection domain of the present utility model.
