See also the circuit theory diagrams of transmitter shown in Figure 3.Transmitter is made up of three-phase supply testing circuit, first oscillatory circuit, first timing circuit, radiating circuit, transmitter DC power supply circuit five parts not shown in the figures.When ABC three-phase supply power supply just often, transmitter module FMK is interrupted the emission normal signal, when the ABC power cut-off, FMK quits work.Wherein:
1. the three-phase supply testing circuit is made of identical two-way single-phase alternating current power sense circuit, the AC power testing circuit of one road AB phase is composed in series successively by AB commutating phase circuit R7-R8-D2, optical coupled switch IC4, comparer IC6, the input diode of the output serial connection optical coupled switch IC4 of rectification circuit R7-R8-D2, the output of optical coupled switch IC4 connects the negative input end of comparer IC6 after capacitor C 9 filtering, the reference voltage signal of the positive input termination stabilivolt DW1 of comparer IC6.

A, B, 3 of C connect the 380V AC power.The output of comparer IC6 in the two-way single-phase alternating current power sense circuit all connects the 15 pin preset ends of the timer IC3 of first timing circuit, the 3 pin signals of astable oscillator IC2 connect the 14 pin clock end of timer IC3, and the output terminal Q6 of the timer IC3 of first timing circuit meets the reset terminal of self and the gauge tap BG1 of transmitter module.As the output terminal Q5 of timer IC3 when being high, gauge tap BG1 conducting, transmitter module FMK obtains electricity work, and emission finishes when Q5 is low.Launch time, length was determined by C5.
The following describes the principle of work of transmitter:
As A, B, all just often optical coupled switch IC4 and IC5 output terminal are noble potential to 3 of C, the 2 pin current potentials of LM393 are higher than 3 pin, make 1 pin output electronegative potential.This electronegative potential does not have influence to the work of timer IC3, and timer IC3 repeats the process of timing-make zero under the clock signal effect of astable oscillator IC2.When timer IC3 timing when being high to its output terminal Q5, gauge tap BG1 conducting, transmitter module FMK obtains electricity work, and after this timer IC3 continues timing, and when low, transmitter module FMK launches end until Q5.After a clock signal, the output terminal Q6 of timer IC3 is high, makes self to reset timer IC3 timing again again.So, transmitter is the intermittent transmission signal again and again, is under the normal condition with the three-phase alternating-current supply that shows transmitter terminal.
When A point or the outage of B point, optical coupled switch IC4 output terminal is electronegative potential, the 2 pin current potentials of LM393-1 are lower than 3 pin, thereby make 1 pin output noble potential, and by 15 pin presets of D3 with IC3, make IC3 stop timing, because the output terminal Q5 of timer IC3 is always low, make transmitter module FMK not work, thereby make transmitter be in alarm condition all the time.
Process during the outage of C point is the same.

The output of JMK receiver module connects the reset terminal of timer IC3 by D1, and the 3 pin signals of astable oscillator IC2 connect the 14 pin clock end of timer IC3, and the output terminal Q9 of timer IC3 connects the input end of gauge tap BG1.When the output terminal Q9 of timer IC3 was low, warning circuit was not worked.As the output terminal Q9 of timer IC3 when being high, gauge tap BG1 conducting, the loudspeaker Y1 of warning circuit obtains electric sounding.
The following describes the principle of work of receiver:
Timer IC3 carries out timing under the clock signal effect of astable oscillator IC2.At the three-phase supply of transmitter terminal between normal epoch, before timer IC3 timing completely, receiver module JMK can receive the signal that transmitter module is sent, and output high level position signal resets timer IC3, so timer IC3 repeats the process of timing-make zero.During this period, the output terminal Q9 of timer IC3 is always low, and warning circuit is not worked.
After the three-phase supply outage of transmitter terminal, transmitter is in alarm condition, and receiver module JMK can not receive the signal of transmitter module.When treating that timer IC3 timing is full, its output terminal Q9 is high, gauge tap BG1 conducting, and the loudspeaker Y1 of warning circuit obtains electric sounding, thereby sends warning, and the prompting receiver has not received the signal of transmitter.
In addition, in transmitter, can be at the output terminal sending and receiving optical diode LED1 of first oscillatory circuit, to indicate as work.In receiver, can be at the LED 2 of the output terminal usefulness taking alarm of the timer of second timing circuit.
The alternating current of considering receiver end may cut off the power supply, and can comprise receiver power supply cut-offing alarming circuit 9 (Fig. 1) at receiver circuit.Ask for an interview Fig. 2.Receiver power supply cut-offing alarming circuit 9 is connected in series formation successively by battery DC, relay J QX, electronic switch BG2, the 3rd oscillator IC4 (NE555), warning circuit (LED3, BG3, Y1), the coil of this relay J QX and the direct supply of receiver also connect, and its normally closed contact is serially connected between this battery DC and this electronic switch BG2.D3 plays buffer action with battery DC diode in series.D2 stops the isolating diode of DC6V to IC2, IC3, JMK and peripheral circuits power supply thereof.
Power just often when the 220V of receiver power supply, JQX works, and its normally closed contact disconnects, and IC4 and peripheral circuits are not worked.When the 220V of receiver power cut-off, JQX is dead electricity simultaneously, and its normally closed contact closure is powered by D3 by 6VDC, the C8 charging, the BG2 conducting, the 2 pin step-downs of IC4,3 pin output noble potential, make the BG3 conducting by R11, Y1 obtains electric sounding, and 3 pin of IC4 also make LED3 luminous by R10, the 220V power cut-off of prompting receiver own.
The utility model in use; transmitter is installed in Circuit Fault on Secondary Transformer or the power tip that needs protection; receiver is placed on people place on duty; when the destroyed and outage of transformer or electric wire; receiver can be reported to the police in ten seconds; remind the operator on duty abnormal conditions to occur, under 3 kilometers situation of intervisibility open ground distance, can grasp robber's feelings of power transformer and cable.
