Description of drawings
Fig. 1 is the circuit structure diagram of the utility model outage automatic reset device.
Embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail, but execution mode of the present utility model is not limited thereto.
Embodiment
As shown in Figure 1, a kind of outage automatic reset device comprises:
Secondary linked switch (KM1--KM2), AC electromagnetic coil (KM3) and trigger-type button (SB); Wherein, a normal open switch (KM1) series connection of secondary linked switch (KM1--KM2) is in the circuit loop of belt switch electrical appliance (A); Trigger-type button (SB) is in parallel with the circuit branch of being made up of belt switch electrical appliance (A) and normal open switch (KM1) after contacting with AC electromagnetic coil (KM3) again; Simultaneously, the branch road that is composed in series by two branch switchs (KM1--KM2) in the linked switch is in parallel as the self-sustaining branch road and the trigger-type button (SB) of AC electromagnetic coil (KM3), or the branch road that is made of separately another branch switch (KM2) is in parallel as the self-sustaining branch road and the trigger-type button (SB) of AC electromagnetic coil (KM3);
Comprise that also one is used for the time relay (K) of clicking trigger formula button (SB), the described time relay (K) is provided with normally closed switch (KM5), is preset with the timer (not shown) of timing and the control unit (not shown) of controlling normally closed switch (KM5) according to timer; The described time relay (K) is serially connected in and is positioned at normal open switch (KM1) between the external electric line of force live wire and zero line in addition.
By a time relay (K) is set, except manually finishing clicking trigger formula button (SB), to carry out outside the power-off restoration startup, can also set the timing (as 5S, 10S) of timer, when timing arrives, control unit will enable normally closed switch (KM5) and click hairdo button (SB), start to carry out intelligentized power-off restoration.
The utility model also comprises a normally closed switch (KM4) that matches with AC electromagnetic coil (KM3), normally closed switch (KM4) is formed series arm with a divider resistance (R), LED light, is connected to be positioned at normal open switch (KM1) between the external electric line of force live wire and zero line in addition.When sending a telegram here after the outage, LED light is bright, to play the alarm effect again.
The button of automatic disconnection after moment connection when described trigger-type button SB is a kind of the click.
The utility model operation principle is as follows:
After the current supply circuit outage, belt switch electrical appliance (A) quits work.Secondary linked switch this moment (KM1--KM2) loses magnetism under the effect of spring by automatic disconnection because of AC electromagnetic coil (KM3), and normally closed switch (KM4) is in closure state, but because the current supply circuit outage, so LED light does not work; Belt switch electrical appliance (A) and AC electromagnetic coil (KM3) all are in open-circuit condition; When powering once more, because AC electromagnetic coil this moment (KM3) does not have magnetic, can't adhesive secondary linked switch (KM1--KM2), so secondary linked switch (KM1--KM2) is in normally open, normally closed switch (KM4) is owing to be in closure state, LED light does not work, be connected in electrical appliance (A) loop owing to branch switch (KM1) again, the loop is in open-circuit condition, even thereby the switch (S) in the belt switch electrical appliance (A) is in on-state, electrical equipment (L) can not worked yet, thereby reaches energy-conservation, purpose of safety.
At this moment, if the people is for pressing trigger-type button (SB), then AC electromagnetic coil (KM3) makes the loop of belt switch electrical appliance (A) loop and solenoid (KM3) all be in status of electrically connecting because of energising produces magnetic with secondary linked switch (KM1--KM2) adhesive; The energising of electrical equipment this moment (L) whether can be by controlling from belt switch (S): if the switch (S) in the belt switch electrical appliance (A) was in on-state originally, electrical equipment (L) will be switched on and be worked; If electrical equipment (L) is not worked, then switch S must be disconnected.
On the other hand, after the outage, decide timer and pick up counting, when timing has arrived and do not have manually and click, control unit will enable normally closed switch (KM5) and click hairdo button (SB), start to carry out intelligentized power-off restoration.
The foregoing description is the utility model preferred implementation; but execution mode of the present utility model is not restricted to the described embodiments; other any do not deviate from change, the modification done under spirit of the present utility model and the principle, substitutes, combination, simplify; all should be the substitute mode of equivalence, be included within the protection range of the present utility model.
