Fig. 3 and Fig. 4 is that one kind of electricity-saving controller of the present invention is embodied as circuit diagram.
Specific embodiment
The embodiment that develops simultaneously below in conjunction with the accompanying drawings describes in detail to the present invention.
The invention provides a kind of automatic detection power device and electric network state and can delay cut-off electricity-saving controller, if
It is placed in the supply line of power device, for controlling whether electrical network accesses power device.As shown in figure 1, controlling when pressing economize on electricity
After the button switch of device processed, electricity-saving controller is triggered, and it connects the connection between electrical network and power device first so that economizing on electricity
Controller and power device are both powered up work.Delay cut-off process within electricity-saving controller is started working simultaneously.Delay cut-off
Process is used for into line delay timing, in timing course, the power of electricity-saving controller real time automatic detection supply line, and power can
Whether working properly to embody electrical equipment, or whether electrical network power normally, the power general if all gone well, on electrical network
Reach a certain height, if too small then it is assumed that with the presence of abnormal factor.Therefore, electricity-saving controller judges whether power is more than
Or it is equal to pre-set threshold value, once this situation it is determined that power device enters normal operating conditions, delay cut-off process is automatic
Stop, and keep the connection between electrical network and power device, to continue to the normal operating conditions of power device.If in meter
When the time in, power on electrical network is less than pre-set threshold value always, then when delay time reaches, cut-out power device and electrical network it

S.Double-pole switch S includes two terminals linking：S-1 terminal and S-2 terminal, the on off state of this two terminals is identical.
Accessing original state on electrical network is to the supply line of power device is the gate-controlled switch disconnecting, the two of gate-controlled switch
The S-1 terminal of end double-pole switch S in parallel.
Power supply circuits, the electric energy for producing provides to power-sensing circuit, ON-OFF control circuit and timing circuit, supplies
S-2 terminal is accessed on the supply line between circuit and timing circuit.
Power-sensing circuit, for detecting the power of supply line that electrical network is powered to power device, if power is more than
Or be equal to pre-set threshold value, then extract, from supply line, the storage capacitor energy storage that electric power is timing circuit, otherwise, do not provide energy storage
Energy.
Timing circuit, for when power supply circuits or power-sensing circuit provide electric energy, storing electrical energy；Using carrying out self-powered
The power supply electric energy of circuit or power-sensing circuit or storage capacitor provide break-make control voltage to ON-OFF control circuit；In power supply electricity
When road and power-sensing circuit do not provide electric energy, the storing electrical energy of storage capacitor is consumed in the delay time t setting.Should
Power supply circuits can be independent current source, such as battery it is also possible to obtain supply line between gate-controlled switch and power device
Power taking source, and be converted to DC voltage, it is supplied to power-sensing circuit, ON-OFF control circuit and timing circuit.Work as gate-controlled switch
K-1 disconnects, and double-pole switch S is also at normally open simultaneously, and power supply circuits are stopped power supply at once, relay K dead electricity, its contact K-
1 maintains a normally open state.When in power device running, electrical network has a power failure suddenly, relay K dead electricity, its contact is restored immediately to often
Open state, double-pole switch S is also at normally open, once incoming call, because K-1 and S switchs all in normally open, in electrical network
Electric current will not impact to power device, and it also will not be made to rework.

When switch S is pressed, S-1 terminal is switched on, and electrical network is powered to power device, meanwhile because linkage is closed
System, switch S-2 is also pressed simultaneously, then power supply circuits provide instantaneous electric energy to timing circuit, and timing circuit is in storing electrical energy
While provide break-make control voltage to ON-OFF control circuit, after the controlled loop conducting in ON-OFF control circuit, gate-controlled switch
Closure, now electrical network is lasting powers to power device.
When switch S is released, S-1 terminal and S-2 terminal are all cut-off, terminate because storage capacitor has charged, because
This can continue as ON-OFF control circuit using stored energy and power, then the closure state of gate-controlled switch is maintained, electrical network
Continue to power to power device.Assume that power device leads to the power in electrical network supply line to be less than because of dormancy, failure and other reasons
Pre-set threshold value, then not to storage capacitor charging, then storage capacitor loses power supply circuits to power-sensing circuit and power detection is electric
This two supply sources of road, can only lean on itself energy storage to provide break-make control voltage for ON-OFF control circuit, thus maintaining gate-controlled switch
Closure, reach the delay time t of setting when the power consumption time of timing circuit, and power-sensing circuit do not have between
Electrical network supply line is detected and recover power, then because energy storage exhausts, the power supply source of ON-OFF control circuit disappears, on-off control electricity
Road disconnects gate-controlled switch, thus having cut off the connection between electrical network and power device it is achieved that time delay disconnects.
After switch S is released, if power device normal work always, or just recover from dormancy, failure and other reasons
Often, as long as occurring in that normal operating conditions, then power-sensing circuit can lead to overpowering change-detection at once to this state, thus
There is provided electric energy for storage capacitor in timing circuit, make storage capacitor stored energy and provide break-make to control electricity to ON-OFF control circuit
Pressure, ON-OFF control circuit connects the connection between electrical network and power device.When power device dormancy or after fault again, it is fixed to rely on
When circuit provide time delay disconnect service.

Put power significantly decline enter standby or off-mode after delay cut-off process just can work.Mix up in feedback resistance R5
Afterwards, heighten bleeder resistor R1 to determine delay cut-off time, the resistance of bleeder resistor R1 and the positive correlation of delay cut-off time.Send out
Optical diode VD10 is controller itself working station indicator, and after pressing double-pole self-resetting button switch S-1, circuit obtains electric
Work, light emitting diode VD10 lights, after relay contact disconnects 220V exchange electrical connection, circuit dead electricity, light emitting diode
VD10 extinguishes.VD12 mainly helps out when circuit is demarcated and debugs.
In sum, these are only automatic detection power device and electric network state and can delay cut-off electricity-saving controller
