In the above-mentioned specific embodiment, the contact of magnetic latching relay K is a normally-closed contact, and its operation principle is:
When inserting the use of AC220V electrical network and electrical equipment, as shown in Figure 1:
Usually the appliances power source and the stand-by energy-saving automatic shutdown circuitry 2 that insert on master control position and the controlled position all are in off-state, if need " start resets ", only need flicking reset button KB, when normally opened contact NO presses the L line of connection electrical network and the moment of pulse generation unit C1, VD1, normally-closed contact NC disconnects the resetting coil L1 of magnetic latching relay, the highest voltage stabilizing value that boosts to voltage stabilizing didoe VD1 of energy storage capacitor C1 charging energy storage simultaneously; When the moment that reset button KB lifts, normally opened contact NO recovers the off-state with pulse generation unit C1, VD1, the connection of normally-closed contact NC recovery simultaneously and pulse generation unit and magnetic latching relay resetting coil L1, storage capacitor C1 forms discharge pulse to resetting coil L1, make the normally-closed contact K-L1 adhesive of magnetic latching relay be reset to " normally closed " state, and by contact K-L0 and the connection of electrical network L line, the electrical equipment and the stand-by energy-saving automatic shutdown circuitry 2 that at this moment insert on master control position and the controlled position are all connected the AC220V power supply.
As seen: except that the instantaneous time that reset button KB presses, normally opened contact NO makes pulse generation unit C1, VD1 be in off-state always at ordinary times, realized on the not only principle of boot-strap circuit 1 of resetting static " zero-power ", and after " keying start ", when 2 operations (dynamically) of stand-by energy-saving automatic shutdown circuitry, boot-strap circuit 1 also " no power consumption " resets.
After " start resets " energising, insert subsequently on master control position and the controlled position the electrical equipment start routinely operation get final product operate as normal, simultaneously, stand-by energy-saving automatic shutdown circuitry 2 must be established beginning ultramicro power-consumption standby operation by cable.
Beginning, power driving circuit is in cut-off state, and the shutdown accumulation power supply begins the energy storage of charging, and time-delay progressively boosts to the DC voltage-stabilizing value; On the other hand, along with the rising of direct voltage, the off signal sample circuit is also started working and is detected sampled signal, send the idle power-off supervisory circuit to monitor comparison process, and the result that will monitor send power driving circuit.The electrical equipment start operate as normal on the master control position is inserted in the back if power on, and stand-by energy-saving automatic shutdown circuitry 2 just is in the ultramicro power-consumption standby operation always.
The shutdown if the electrical equipment on the access master control position is finished using, or city's net AC220V burst has a power failure, " becoming 0 " unloaded off signal voltage that the off signal sample circuit will in time detect, send idle power-off supervisory circuit comparison process, if the standard value that is lower than the standby power of setting is (at the standby power grade in electric equipment products such as a large amount of household electrical appliances and office series different application field, can set by demand), then export a high level and make the power driving circuit conducting, the shutdown accumulation power supply forms discharge pulse to the actuation coil L2 of magnetic latching relay K, the normally-closed contact K-L1 of magnetic latching relay is disconnected, thereby cut off the power supply that inserts the system on master control position and the controlled position automatically, also automatic disconnection shutdown accumulation power supply is realized safety " Zero-power-consumption standby ".Again start if desired only needs flicking reset button KB to get final product.
After powering on, fail in time to start shooting operate as normal if insert electrical equipment on the master control position, the idle power-off supervisory circuit (can be set automatic time delay on demand, time by the charging energy storage of shutdown accumulation power supply is determined) the output high level also makes the power driving circuit conducting, the shutdown accumulation power supply forms discharge pulse to actuation coil L2, magnetic latching relay K-L1 contact is disconnected, thereby cut off the system power supply that inserts on master control position and the controlled position automatically, disconnect because of the K-L1 contact simultaneously, also automatic disconnection shutdown accumulation power supply is realized safety " Zero-power-consumption standby ".Again start if desired, the same needs flicking reset button KB to get final product.
As shown in Figure 2, in the foregoing description, the contact of magnetic latching relay K or for often opening/normally closed conversion hysteria contact, wherein normally opened contact K-L2 is connected with the power input of the boot-strap circuit 1 that resets, the input of the L inlet wire of normally-closed contact K-L1 and master control position and controlled position and the shutdown accumulation electrical source of stand-by energy-saving automatic shutdown circuitry 2 is connected, and common K-L0 is connected with the L inlet wire of AC220V electrical network.
Its operating principle and above-mentioned normally-closed contact are similar, but because the input of the boot-strap circuit 1 that resets is connected with the L inlet wire of electrical network by normally opened contact K-L2, have further increased reliability.
Ubiquitous " standby energy consumption " problem during the utility model is extensive use of at present a large amount of household electrical appliances, office electrical equipment, a kind of static zero consumption energy-saving safe conversion equipment is provided, by master control position an intelligent control module is set at the energy-saving safe conversion equipment, intelligent control module comprises the power magnetic force keeping relay, the static zero consumption that only need pulse excitation control reset boot-strap circuit and stand-by energy-saving automatic shutdown circuitry, and its connects the input of master control position socket; Reset boot-strap circuit and stand-by energy-saving automatic shutdown circuitry of described static zero consumption takes turns starting work, the stand-by energy-saving automatic shutdown circuitry is to controlled electric appliance shutdown enforcement monitoring and automatic disconnection electric system power supply, realize safety " Zero-power-consumption standby ", simultaneously for further energy-conservation, reduce oneself power consumption, also automatic disconnection shutdown circuit accumulation power supply; The start that resets only needs the ad hoc the Reset button of flicking can recover electric power supply, auto power off is implemented in shutdown to controlled household electrical appliances, office electrical equipment, make electrical equipment be in safety " Zero-power-consumption standby ", do not change the custom that the user uses keying type household electrical appliances, office electrical equipment again.
In the specific embodiment, can comprise respective gut between jack housing, electrode box and the electrode thereof, be provided with a socket aperture at least on shell, it is master control position socket that socket has only a baseplug hole, and all the other socket apertures are controlled position.Intelligent control module connects the input of master control position socket, if the outage of master control position, other all outage of controlled position.
