The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 illustrates the utility model and is pressed with plug 9, the power supply test button 4 (K1) of cabinet door state sensing element 2 that electric language warning device body 1 and cabinet door open and close, magnet piece 3, sensing element 2 by height and electric test button 5 (K2) is arranged and line 12 and plug 8,7,6 are formed.On the panel of device body 1, be provided with three jacks 13,14,15, be connected with plug 6,7,8 through lead 12 respectively, constitute one independently to the monitoring system of electric field.Cabinet door state sensing element 2 is a normally closed type tongue tube T, and all the other also have: test button 11 (K3), light emitting diode lamp 10.
Fig. 2～5 illustrate the installation site of device body 1 of the present utility model on high-tension switch cabinet lower left side (or right side) wall.Cabinet door state sensing element 2 is installed on the upright doorframe 18 of switch cubicle, magnet piece 3 is bonded on the high-tension switch cabinet lower gate 19 and makes it and sensing element 2 guarantees to have certain interval behind the door closing, power supply test button 4 and have electric test button 5 to be loaded on the upright doorframe 18 in switch cubicle middle part by boring.The plug 6,7,8,9 of lead-in wire 12 is inserted respectively in the jack of jack 13,14,15 and sensing element 2.All the other are: high-tension switch cabinet high voltage load cable 16, high-tension switch cabinet wiring chamber door 17.
Fig. 6 illustrates circuit theory of the present utility model.Main testing circuit and warning circuit two parts of dividing.
The testing circuit part: the holding circuit that induction metal plate J forms through R1, diode BG1 connects the grid of field effect transistor BG2; the BG2 drain electrode connects power positive end, links to each other with transistor BG3 base stage simultaneously through R2, R3; BG3 and peripheral cell R5, R4 and BG4 constitute amplifier stage; the BG3 collector connects the base stage of transistor BG5 through R6; the emitter of BG5, collector be connected across between the anode of this circuit anode and warning circuit, as the power supply of electronic switch control warning circuit; C3, C4 are anti-interference capacitor, and C2 is a power filtering capacitor.
The warning circuit part: form the language alarm circuit by language integrated circuit (IC) 1, power amplifier integrate circuit IC2, loudspeaker Y etc., light emitting diode BG6 and current-limiting resistance R7 thereof form light warning indicating circuit.R9, R10, C6 are the peripheral cell of IC1, and R3 and stabilivolt BG7 form the power supply stabilization circuit of IC1.R11 is the peripheral cell of IC2, and C7, C8 are coupling capacitance, and C5 is the power filtering capacitor of this part.
Power supply E positive pole is through normally closed type tongue tube T (2), for above-mentioned two parts circuit provides operating voltage.There is electric test button K2 (5) in parallel with T, power supply test button K1 (4) is connected between the anode of power supply E positive pole and warning circuit, two groups of normally closed contacts of test button K3 (promptly 11) connect the positive and negative electrode of power supply E respectively with the positive and negative electrode of C1, and one group of negative pole with C1 of its two groups of normally opened contacts connects the negative pole that testing circuit input end, another group connect the positive pole of C1 power supply E.
When high-tension switch cabinet internal loading cable or bus 16 have voltage; the sheet metal that is located at device body 1 inwall has signal voltage with induction; as this moment the switch cubicle door open; tongue tube T contact is connected, i.e. energized, and then signal voltage is added to the BG2 grid through R1, BG1 holding circuit with reverse voltage; BG2 is ended; the BG2 drain voltage raises, and makes the BG3 conducting, and then makes the BG5 saturation conduction.It is electric that the BG5 conducting gets warning circuit, language IC circuit 1, IC2 work, and loudspeaker Y sends the caution signal of " electricity is arranged, and Danger!
