Description of drawings:
Fig. 1 is circuit theory diagrams of the present utility model.
Embodiment:
As shown in Figure 1, this battery saving arrangement includes the mains ac power supply input socket, and load power source is by control socket, the low-voltage direct working power, the loaded work piece current sensing means, detection signal transition processing device, adjustable potentiometer, comparator, trigger, bidirectional triode thyristor, start button.Trigger is the centralized control unit of this battery saving arrangement, accepts start button signal, standby signal as the control input of opening or turn-offing, and keeps stable state and output control controllable silicon.
The loaded work piece current sensing means is an interchange magnetic induction loop, and its inductive load operating current also produces ac voltage signal, transfers the negative pole that direct voltage is given voltage comparator to by the detection signal transition processing device.During loaded work piece, it is bigger to detect direct voltage, owing to connect the negative pole of comparator, at this moment comparator is output as low level; Otherwise it is less to detect direct voltage during standby, and comparator is output as high-low level.Therefore, when load turns to the holding state process from operating state, comparator will be exported a rising edge, this rising edge as the time trigger the synchronised clock input make trigger generation homing action output low level (because the RESET input K of trigger connects high level all the time in the circuit), thereby the power supply of control bidirectional triode thyristor switching off load live wire reaches the function that automatically shuts down the load power source socket when entering holding state.Because the retention performance of trigger stable state, off state remains to always manually to be pressed till the start button next time.
Trigger can be CD4027.
Need open controlled load power source socket when next time, only need touch start button, export a high level, it meets the set end S of trigger, the power supply that makes trigger output high level control bidirectional triode thyristor open the load live wire, load power source is in the normal power supply state by control socket.Because trigger stable state
Retention performance, even unclamp start button, open state also remains to next load always and enters till the holding state.Also can increase the time delays device, the open state of start-up by hand is delayed time a fixed time when load does not enter operating state, and (as 3 minutes) automatically shut down again.
The adjustable potentiometer of battery saving arrangement is an adjustable resistance, for voltage comparator provides an adjustable canonical reference voltage.Adjustable potentiometer is arranged at the load standby power of different positions when just having determined the shutoff of different sizes.Because the power difference when its standby power of dissimilar load equipments and operate as normal is very big, the standby power of the powerful device that has (as air-conditioning) may be also bigger than the operate as normal power (as charger) of the low-power equipment that has.Adjustable potentiometer has been arranged, just can make this section electric installation satisfy the power consumption equipment of different stand watt level.
The utility model and former device comparison have reduced single-chip microcomputer, reduced cost, have strengthened reliability.It has versatility, can use for each electric appliances, reaches the purpose of electrical energy saving and safety utilization of electric power, does not influence the normal use of electrical equipment.
