Description

Energy-saving display lamp flashing device

The utility model be a kind of send out, for the position of isolating switch on, the distribution control loop and gauge tap not at once, the energy-saving indicating lamp flasher that various pilot lamp are glistened, this flasher is made up of control circuit and shell.

It is big that power consumption is generally all continued to use in China's electric system, flimsy XD ₅, XD ₁₃Etc. old-fashioned pilot lamp, this does not meet China's national situation, relevant department has proposed improvement idea, along with the invention of energy-efficient pilot lamp and sending out, supply, use on the breaker tripping and closing control loop of distribution department and power distribution room, it is big to have remedied old-fashioned pilot lamp power consumption, flimsy defective, but because energy-efficient pilot lamp direct impedance is big, electric current is less in the loop, old-fashioned pilot lamp flashing relay (being the pilot lamp flasher), this flashing relay are series resistors between power supply signal+XM and (+) SM flash of light bus, be connected to behind relay and the capacitor in parallel on the flash of light bus of secondary circuit in the former power transformation system with relay.This flashing relay can not be big by direct impedance, the less energy-efficient pilot lamp of electric current starts in the loop, thereby in breaker tripping and closing control loop and the position of the switch not to having lost this important function of flash of light at once, limited energy-efficient pilot lamp send out, use in power supply department and the power distribution room breaker tripping and closing control loop.

Task of the present invention is a kind of new energy-saving indicating lamp flasher of design.It can make the big XD of power consumption simultaneously ₅, XD ₁₃Etc. old-fashioned pilot lamp and energy-saving other high-level efficiency pilot lamp in breaker tripping and closing control loop and the position of the switch not to glistening at once.And various pilot lamp are used alone or as a mixture.The wiring of this flasher is simple, and cost is low, reliable operation.Be not subjected to the interference of extraneous power supply, and can control the flash circuit that is at least several milliamperes to several amperes.

Below in conjunction with accompanying drawing the technical solution of the utility model is explained in detail.

Fig. 1 is circuit theory diagrams of the present utility model.

Fig. 2 is a shell synoptic diagram of the present utility model.

External signal power source both positive and negative polarity in control circuit (+XM ,-XM) between successively series resistor 3R, relay J and at relay J two ends shnt capacitor C, it is a pair of to succeed electrical equipment J normal opened contact between (+) SM flash of light bus on signal power source+XM and the former power transformation electrical secondary system control loop. Main feature of the present utility model be external signal power source+XM and-XM between series resistor 1R, dividing point A, Zener diode DW, the base loop of current-limiting resistance 2R and triode 1T, the another terminal 3 of dividing point A joins with (+) SM flash of light bus of former power transformation electrical secondary system control loop. Send out, for the position of breaker on, the distribution control loop and gauge tap at once not forming bleeder circuit by (+) SM former power transformation electrical secondary system control loop indicator lamp load that bus incorporates into of glistening through dividing point A and resistance 1R. The colelctor electrode of triode 1T and 4R are connected to the D point, and the 4R other end and signal power source+XM join, and the base stage of triode 2T is joined through 5R and contact D, and colelctor electrode and the relay J of triode 2T are joined, and emitter stage and the signal power source-XM of triode 1T, 2T join. The negative terminal of Zener diode DW meets dividing point A, its positive termination current-limiting resistance 2R. The resistance of current-limiting resistance 2R must be less than the maximum requirement of the base loop current requirements of triode 1T when dividing point A full voltage.

Operation principle of the present utility model is because Zener diode DW is serially connected on the base loop of triode 1T through current-limiting resistance 2R, therefore Zener diode DW is the switching tube of triode 1T, because having adopted two triode 1T and 2T, relay J consumed energy not when making breaker and gauge tap corresponding in the position. Since the signal power source both positive and negative polarity (+XM ,-adopt resistance 1R between XM), Zener diode DW and current-limiting resistance 2R divide Press, dividing point A between resistance 1R Zener diode DW and the current-limiting resistance 2R directly is connected on (+) SM flash of light bus of former power transformation electrical secondary system control loop, the control loop of flash of light bus and former transformer substation system joins, like this in breaker and gauge tap KK position at once, be distributed in voltage on the dividing point A greater than the voltage of voltage regulation of Zener diode DW, because dividing point A does not have external load and incorporates into, signal power source+XM forces Zener diode DW to be in conducting state, also make simultaneously triode 1T be in conducting state (such Zener diode DW plays triode 1T base loop and opens), at this moment, triode 2T cut-off, relay J is not worked, and the normal opened contact of relay J is in open mode. When the position of breaker and gauge tap KK not at once; indicator lamp on the former control loop is led on flash of light bus (+) SM by change-over switch contact KK; because of the Zener diode DW on indicator lamp and the dividing point A; the base loop parallel connection of current-limiting resistance 2R and triode 1T; make the voltage drop of dividing point A to the cutoff of Zener diode DW; this moment, Zener diode DW was in cut-off state; triode 1T base loop does not have electric current to flow through; make triode 1T also be in cut-off state; (from then on find out; the electric current that the base current of triode 1T and Zener diode DW flow through is determined by dividing point A); triode 2T conducting this moment; capacitor C charging also starts relay J; since be subjected to the normal opened contact of Control be connected on+XM and dividing point A between; after the relay normally open contact closure; signal power source+XM directly is added on the dividing point A by normal opened contact; linked to each other with (+) SM flash of light bus of former power transformation electrical secondary system control loop by dividing point A; make the indicator lamp that is connected on (+) SM flash of light bus luminous and make simultaneously Zener diode DW under full voltage; (at this moment current-limiting resistance 2R plays metering function in this loop for current-limiting resistance 2R and triode 1T conducting; protect this loop to avoid the impact of the full voltage on the dividing point A and damage no part); make triode 2T cut-off; relay J is returned; (relay J is subjected to the impact of the electric energy of capacitor C can prolong the time of return of relay J;) after relay J returns; opened by the normal opened contact of relay J control, because (+) SM The full voltage of flash of light bus loss signal power supply+XM makes again voltage on the dividing point A be lower than the magnitude of voltage of Zener diode DW, stops electric current to pass through, and makes triode 1T cut-off, again conducting of triode pipe 2T. So continuous circulation can constantly be glistened the indicator lamp on the control loop under full voltage, played the effect of energy-saving display lamp flashing device.

Shell can become various external form moulding by various material such as plastics and organic glass, and its binding post symbol 1,2,3 connects the signal power source+XM terminal 1 in the electrical schematic diagram respectively, (+) SM flash of light bus terminal 3 of signal power source-XM terminal 2 and secondary circuit.

The utility model has the advantages that wiring is simple, cost is low, and reliable operation is not subjected to the interference of extraneous power supply and can controls the flash circuit that is at least several milliamperes to several amperes.
