The electrifying protection breaker is generally connected with an input end of an external circuit, when the external circuit is cut off, power is cut off in a family at the same time; when the external circuit is electrified, the family can be electrified only until the trigger button is pressed again, thereby ensuring the use security of electric equipment and avoiding accidents.
Description
Technical field
The utility model belongs to breaker technical field, is specially a kind of energising protective circuit breaker.
Background technology
Generally, electricity is arranged on the socket of family, heating up water with electric iron pressing, insulating pot or other power consumption equipment when working, if broken suddenly, and again because work is busy or other reasons is forgotten and cut off the electricity supply, when incoming call, just in case the people does not exist, power consumption equipments such as electric iron, insulating pot can work on again, not only wasted, and electric iron length heating time one can burn clothes and cause fire, and insulating pot also might dryout, and its consequence is hardly imaginable.
The utility model content
At the above-mentioned problems in the prior art; the purpose of this utility model is to design the technical scheme that a kind of protective circuit breaker of switching on is provided; when external circuit cuts off the power supply; family has not had simultaneously yet; when external circuit is sent a telegram here, have only to click trigger button again, family just has; ensure the safe in utilization of power consumption equipment, avoided the accident generation.
Described energising protective circuit breaker; it is characterized in that comprising circuit breaker; ac solid relay; trigger button and DC power supply device; 1 of circuit breaker; 3 pin respectively with the input live wire; the input zero line connects; 2 pin of circuit breaker are connected with 1 pin of ac solid relay; trigger button is connected in parallel on 1 of ac solid relay; on 2 pin; 2 pin of ac solid relay and 1 pin of DC power supply device are connected on the output live wire; 3 of ac solid relay; 4 pin respectively with 4 of DC power supply device; 3 pin connect, and 2 pin of DC power supply device and 4 pin of circuit breaker are connected on the output zero line.
Described energising protective circuit breaker is characterized in that parallel resistance R, LED on 2,4 pin of described circuit breaker.
Described energising protective circuit breaker, its feature is 3-32V in the trigger voltage of described DC power supply device.
Described energising protective circuit breaker, its feature is provided with the out-put supply indicator light on described DC power supply device.
Described energising protective circuit breaker, its feature is provided with relay indicating light on described ac solid relay.
Above-mentioned energising protective circuit breaker, be skillfully constructed, simple in structure, be connected on the input of external circuit usually, when external circuit cuts off the power supply, family does not have electricity simultaneously yet, cuts off the power supply on the output live wire, and the DC power supply device also cuts off the power supply, make also outage of direct current output, thereby make 3,4 pin of ac solid relay control end lose voltage, 1,2 pin of ac solid relay disconnect, and the input live wire is isolated with the output live wire disconnect; When external circuit is sent a telegram here, have only to click trigger button again, family just has electricity, has ensured the safe in utilization of power consumption equipment, has avoided the accident generation.This energising protective circuit breaker also is suitable for the energising protection of power consumption equipments such as factory, enterprise.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a mechanical structure schematic diagram of the present utility model;
Among the figure: 1-circuit breaker, 2-trigger button, 3-ac solid relay, 4-DC power supply device, 5-LED, 6-out-put supply indicator light, 7-relay indicating light.
Embodiment
The utility model is described in further detail below in conjunction with Figure of description:
As shown in the figure, 1,3 pin of circuit breaker 1 are connected with input live wire, input zero line respectively, 2 pin of circuit breaker 1 are connected with 1 pin of ac solid relay 3, trigger button 2 is connected in parallel on 1,2 pin of ac solid relay 3,2 pin of ac solid relay 3 and 1 pin of DC power supply device 4 are connected on the output live wire, 3,4 pin of ac solid relay 3 are connected with 4,3 pin of DC power supply device 4 respectively, and 2 pin of DC power supply device 4 and 4 pin of circuit breaker 1 are connected on the output zero line.Parallel resistance R, LED 5 between 2,4 pin of circuit breaker 1 are done the input indication of external power.On the described ac solid relay 3 relay indicating light 7 is set.The trigger voltage of described DC power supply device 4 is 3-32V, and out-put supply indicator light 6 is set.Described circuit breaker 1 can be a normal domestic use, also can be other; The rated voltage of ac solid relay 3 and circuit breaker 1 and rated current can be the same bigger than circuit breaker 1 of big or ac solid relay 3; Trigger button 2 can be with common miniature button.This energising protective circuit breaker is connected on the input of external circuit usually.
Operation principle is as follows: when external circuit cuts off the power supply, family is outage simultaneously also, 1,2 pin of ac solid relay 3 are not conductings, cut off the power supply on the output live wire, DC power supply device 4 also cuts off the power supply, and makes also outage of direct current output, thereby makes control end 3,4 pin of ac solid relay 3 lose voltage, 1,2 pin of ac solid relay 3 disconnect, and the input live wire is isolated with the output live wire disconnect; When external circuit is sent a telegram here, have only and click trigger button 2 again to voltage of output live wire, make 4 energisings of DC power supply device, thereby low-voltage of 4,3 pin of DC power supply device 4 output removes to trigger control end 3,4 pin of ac solid relay 3, makes 1,2 pin conductings of ac solid relay 3; Unclamp trigger button 2, button disconnects, because 1,2 pin conductings of ac solid relay 3, on the output live wire electricity is arranged still, so DC power supply device 4 still is connected on the power supply, 4,3 pin of DC power supply device 4 also continue output LOW voltage simultaneously, make 1,2 pin of ac solid relay 3 continue conducting, family just can continue to have electricity, has ensured the safe in utilization of power consumption equipment, has avoided the accident generation.
