Description
Technical field
The utility model belongs to technical field of electric appliances, especially relates to a kind of self power-off of timing and exports breaker device.
Background technology
Electrification society now, all be unable to do without electricity everywhere, especially once there is hidden danger in Household electric appliance safety problem, can bring heavy losses to the property of people and life.The utility model patent that application number is " 201220196729.7 " discloses a kind of Novel timing power-off protector; adopt timer; by the time of the knob setting timing of timer; after working on power; reach timing then to control contact switch and automatically disconnect; realize the function of timing and auto-breaking, avoid occurring causing burning out the situation of electrical equipment owing to forgetting power-off to make circuit work continuously.But, the effect that this patent does not reach energy saving and is perfectly safe.
Summary of the invention
The purpose of this utility model is: provide a kind of self power-off of energy-conservation, safe timing and export breaker device.
The technical solution of the utility model is: a kind of self power-off of timing and output breaker device, comprise timer and power control, power control comprises often to be left electromagnetic relay KM I, often opens electromagnetic relay KM II, keyswitch K, 220V power input L1 pole is connected to transformation circuit input L3 end and the 220V power output end L2 pole of timer by connecting terminal A1 and A2 often opening electromagnetic relay KM I, and the two poles of the earth of often opening electromagnetic relay KM I are connected by keyswitch K; The transformation circuit input N3 end that 220V power input N1 pole connects timer is connected 220V power output end N2 pole with connecting terminal B1 with B2 by often opening electromagnetic relay KM II; The 12V direct current signal of timer controls power sources in parallel and connects coil two polar contact often opened electromagnetic breaker KM I and often open electromagnetic breaker KM II.
Further, 220V power input L1 pole and often open between electromagnetic relay KM I fuse is housed.
The beneficial effects of the utility model are: this installation's power source plug is inserted supply socket, switch on power, now this device is not energized work immediately, but need the keyswitch of on this device to press, wait for that could start this device after certain hour starts working, and connect self and out-put supply, can be electrical appliance and 220V power supply is provided, and timing knob can be adjusted according to actual operation requirements and determine required time, completing start setting.After the time reaches and regularly grows, this device quits work, and cuts off own power source and self out-put supply, reaches the power-off object and requirement that control electrical appliance.The utility model can realize the power-off simultaneously of 220V two poles, thus reaches safe object; When stopping, this device and institute's electrical appliance are no longer energized work simultaneously, are zero consumption, play the effect of energy saving, safety.
Accompanying drawing explanation
Fig. 1 is structural principle schematic diagram of the present utility model.
Embodiment
As can be seen from structural principle schematic diagram of the present utility model shown in Fig. 1, the utility model timer 3 and power control two parts composition.Timer is the control realizing the time, and provides 12V signal to control for the electromagnetic relay coil of often opening of power control, and timer is regulated by potentiometer and can realize the time and arbitrarily set.Timer adopts PT8A2512NE, and it is a simple and practical chip, is widely used in small household appliances field.Power control comprises often to be left electromagnetic relay KM I 2, often opens electromagnetic relay KM II 5, keyswitch K1 and fuse 6,220V power input L1 pole is connected to transformation circuit input L3 end and the 220V power output end L2 pole of timer 3 by connecting terminal A1 and A2 often opening electromagnetic relay KM I 2,220V power input L1 pole and often open between electromagnetic relay KM I 2 fuse 6 is housed, the two poles of the earth connecting terminal A1 and A2 point often opening electromagnetic relay KM I 2 is connected by keyswitch K1.The transformation circuit input N3 end that 220V power input N1 pole connects timer 3 is connected 220V power output end N2 pole with connecting terminal B1 with B2 by often opening electromagnetic relay KM II 5.The 12V direct current signal of timer 3 controls power supply 4 and is connected in parallel coil two polar contact often opening electromagnetic breaker KM I 2 and Chang Kai electromagnetic breaker KM II 5, for often opening electromagnetic breaker KM I 2 and Chang Kai electromagnetic breaker KM II 5 provides 12V direct supply, control often to open electromagnetic breaker KM I 2 coil and Chang Kai electromagnetic breaker KM II 5 coil adhesive and disconnection.
Principle of work of the present utility model is: when the K switch 1 that pushes button, 220V power input L1 electrode current can be realized stride across and often open electromagnetic relay KM I 2, by keyswitch K1 direct conducting incoming timing device 3 transformation circuit input L3 end and this device 220V power output end L2 pole, now timer 3 is energized work provide 12V power supply for the coil often opening electromagnetic relay KM I 2 and Chang Kai electromagnetic relay KM II 5, after often opening the coil electricity adhesive of electromagnetic relay KM I 2 and Chang Kai electromagnetic relay KM II 5, often open electromagnetic relay KM I 2 and connect two contact A 1 and A2, often open electromagnetic relay KM II 5 connection two contact B1 and B2 and close conducting, realize 220V power input L1 electrode current directly input L3 hold and this device 220V power output end L2 pole by often opening electromagnetic relay KM I 2 contact A 1 and A2 conducting incoming timing device 3 transformation circuit, closing conducting with often opening electromagnetic relay KM II 5 connection two contact B1 and B2, realizing this device 220V power input N1 pole and connecting contact B1 and the B2 often opening electromagnetic relay KM II 5, with this device 220V power output end N2 pole conducting.Now unclamp keyswitch K1, also can realize timer 3 and continue energising work with this device out-put supply.
After regularly growing to and reaching, timer 3 stops as often opening electromagnetic relay KM I 2 and Chang Kai electromagnetic relay KM II 5 coil reoffers 12V power supply, often open the coil blackout of electromagnetic relay KM I 2 and Chang Kai electromagnetic relay KM II 5, make timer 3 power supply connect two contact A 1 to be separated with A2, B1 and B2 adhesive, cut off the input of 220V power input L1 electrode current respectively, cut off timer 3 and supply with the power supply of 220V power output end L2 pole; The coil blackout of Yin Changkai electromagnetic relay KM II 5 makes power supply two connecting terminal B1 be separated with B2 adhesive simultaneously, also the connection of 220V power input N1 pole and 220V power output end N2 pole has been cut off, realize the power-off simultaneously of 220V power supply (L.N) the two poles of the earth, reach safe object.Now this device returns to again idle standby no-output state, realizes the object of energy-conserving and environment-protective, safety.
