Abstract
The invention relates to an air-switch working-state displaying device. The air-switch working-state displaying device comprises an air switch and three groups of displaying circuits with identical circuit structures; and in order to make up and overcome the defect of no working-state display existing in the traditional air switch, the working state of the air switch can be rapidly judged by additionally installing multiple simple electronic displaying circuits to provide favorable references for electricity users to clear faults and prevented from enlarging the range of the faults or generating electric-shock accidents due to the blind operation of the electricity users. The displaying circuits not only can be used as an upgrading device for the ordinary air switch, but also can be used for researching and developing new-style air switches by using the technical scheme of the displaying circuits.
Description
Technical field
The invention belongs to electronics and electrical technology field, relate to a kind of air switch operating status display apparatus.
Background technology
Air switch is widely used because of many advantages are arranged, and it has replaced basically prolongs the old-fashioned bakelite knife switch of using the sort of band fuse for a long time.But at the frosty face of 220V alternating current transmission line air switch; Its operating state is not directly perceived; As: when air switch tripping operation took place or ran into situation such as power failure night, electricity consumer can't correctly be judged for the moment, particularly to after the power consumption equipment failed because; Electricity consumer is got used to blindly closing a floodgate under not clear situation, is easy to cause because of custom or misjudgment the generation of accident such as fault coverage expansion like this.
There is not the deficiency that operating state shows in order to remedy and to overcome existing air switch; Be necessary to develop a kind of servicing unit that can show the air switch operating state; Make electricity consumer no matter by day or can both know night the operating state of seeing air switch be switched on or switched off, whether the air switch lead-out terminal have electricity etc.; Judging line fault character comparatively exactly for electricity consumer provides foundation or reference, avoids electricity consumer to enlarge fault coverage or electric shock accidents takes place because of blindly operating.
Technology of the present invention both can be used as the air switch servicing unit and had developed separately, also capable of being combinedly carried out supporting exploitation to air switch or multipole air switch assembly inside.
Summary of the invention
Goal of the invention and beneficial effect: in order to remedy and overcome the defective of the no operating state demonstration of existing air switch existence; Through installing simple multiple electronics display circuit additional; Can judge the residing operating state of air switch fast; Fixing a breakdown for electricity consumer provides favourable reference, avoids electricity consumer blindly to operate and enlarges fault coverage or electric shock accidents takes place.Display circuit both can also can use its technical scheme to research and develop trendy air switch as the update device of normal air switch.
Circuit working principle: when 220V alternating current transmission line normal power supply; The display circuit of air switch obtains 5V stable DC voltage by the 220V alternating current through decompression capacitor C2, silicon rectifier diode D2 rectification, voltage stabilizing didoe DW2; Utilize the high bright LED 2 of resistance R 2 current-limiting points shiny reds, in like manner green high bright LED 3 is also lighted luminous.It is because upper and lower two binding posts of air switch K are in on-state that yellow high light tone LED 1 does not work, the event of no-voltage difference between the live wire end L of 220V alternating current and the live wire end L ';
When tripping operation takes place in the air switch K that is connected between the live wire end L of 220V alternating current and the live wire end L ' (disconnection); High shiny red LED 2 keeps lighting; Green high bright LED 3 extinguishes; The zero line side N of yellow light-emitting diode LED1 through power consumption equipment RL and 220V alternating current forms the loop and lighted, and this shows with electric line and overloads or short trouble has taken place power consumption equipment;
After the night air K switch trips; The low-light that high shiny red LED 2 and yellow high bright LED 1 send can be used as the temporary lighting of distribution box; Electricity consumer can be checked the process circuit failure condition by low-light, and the power consumption during display circuit work is very little.Not enough in order to solve high bright light-emitting diode operating voltage, cause the not enough problem of high bright light-emitting diodes brightness, designed stabilized voltage power supply for high bright light-emitting diode reliably working specially in the circuit.Voltage stabilizing didoe has access to two effects: the one, and for the bright light-emitting diode of height provides working power, the 2nd, guarantee that high bright light-emitting diode is not punctured by 220V alternating current reverse voltage.
When the 220V alternating current took place to have a power failure, the air switch K that connects can not trip between the live wire end L of 220V alternating current and the live wire end L ', and 3 high bright LED 1～LED3 on the air switch K circuit all extinguish.Electricity consumer can be bright according to the bright LED 1～LED3 of height and the Different Results that does not work, and judges the nature of trouble of 220V alternating current transmission line fast.
Technical scheme: the air switch operating status display apparatus, to form with 3 groups of identical display circuits of circuit structure by air switch K, its characteristic comprises:
The upper terminal of air switch K meets the electric live wire end L of 220V alternating current, the lower terminal of the air switch K line end L ' that starts to exchange fire;
Yellow display circuit: form by decompression capacitor C1, silicon rectifier diode D1, voltage stabilizing didoe DW1, dropping resistor R1 and yellow high bright LED 1; The electric live wire end L of the termination 220V alternating current of decompression capacitor C1; The positive pole of another termination silicon rectifier diode D1 of decompression capacitor C1; The negative pole of silicon rectifier diode D1 connects the negative pole of voltage stabilizing didoe DW1 and the end of dropping resistor R1; The positive pole of the yellow high bright LED 1 of another termination of dropping resistor R1, the positive pole of voltage stabilizing didoe DW1 links to each other with live wire end L ' with the negative pole of yellow high bright LED 1;
Red display circuit: form by decompression capacitor C2, silicon rectifier diode D2, voltage stabilizing didoe DW2, dropping resistor R2 and red high bright LED 2; The electric live wire end L of the termination 220V alternating current of decompression capacitor C2; The positive pole of another termination silicon rectifier diode D2 of decompression capacitor C2; The negative pole of silicon rectifier diode D2 connects the negative pole of voltage stabilizing didoe DW2 and the end of dropping resistor R2; The positive pole of the red high bright LED 2 of another termination of dropping resistor R2, the positive pole of voltage stabilizing didoe DW2 links to each other with the zero line side N of 220V alternating current with the negative pole of red high bright LED 2;
