The principle of work of described voltage stabilizer is as follows: when needs use this electricity-saving appliance work in the gas-discharge lamp illumination, single-phase AC voltage will enter autotransformer 1 simple of electricity-saving appliance by K switch, it is secondary will to provide output voltage (if three-phase input at lead-out terminal 5, three autotransformer coils, three input terminals 6 and three lead-out terminals 5 then should be arranged, form three-phase output).Output voltage also inputs to described switch controller 85 as feedback voltage signal by feedback terminal 9,10 except supply load FZ uses.K closes a floodgate simultaneously, and the described time relay 80 is according to the deferred action of prior setting, and its normally closed contact 81 makes at first action of contact 20, and is higher from the voltage of lead-out terminal 5 outputs, thereby can light described gas-discharge lamp.Comparer 90 is anti-phase than in-phase voltage height in the time that sets, thereby output low level, and coil 89 gets electric, and relay 86 actions are for contactor 40 is got ready.After the time that sets through one, the described time relay 80 actions, its normally closed contact 81 disconnects, its normally opened contact 82 closures, contactor 40 actions.In some cases, if the voltage on the input terminal 6 is too low or load when crossing brownout on ambassador's lead-out terminal 5, pass through voltage sample, can make the anti-phase lower of comparer 90 than in-phase voltage, then comparer 90 is exported high level, coil 89 dead electricity, and contactor 40 discharges, contactor 30 actions improve output voltage; When opposite, comparer 90 is anti-phase than in-phase voltage height, thereby output low level, and coil 89 gets electric, contactor 40 actions, and contactor 30 discharges, and output voltage is reduced.It is stable that feedback resistance 98 has guaranteed that contactor 30,40 switches mutually.Obviously, such method has guaranteed the relative stability of output voltage, has realized the object of the invention.
Accompanying drawing 2 is second embodiment of the present invention.Principal feature be described voltage-stabilizing controller be connected to three relays 17,17 ' and 17 " singlechip controller 11.Described singlechip controller 11 contains user program panel 12, the single-chip microcomputer 14 that has A/D and OUT mouth and the display screen 13 that connects successively.The function of the described time relay and described comparer can extremely easily realize in single-chip microcomputer 14 and the voltage signal that potentiometer 93 obtains need only be inputed to the single-chip microcomputer 14 with A/D conversion mouth.Thereby the upper end of potentiometer 93 connects the A/D terminal of single-chip microcomputer 14.The coil of above-mentioned contactor is then accepted the relay control that single-chip microcomputer OUT mouth drives.Specifically be the OUT mouth by 3 base resistances 15,15 ' and 15 " drive 3 triodes 16,16 ' and 16 ", so as to controlling 3 relays 17,17 ' and 17 " 3 coils 18,18 ' and 18 ", single-chip microcomputer OUT mouth is according to the program of setting in advance and feedback voltage signal output high level or low level, make 3 relays 17,17 ' and 17 " 3 pairs of normally opened contacts 19,19 ' and 19 " realize voltage stabilizing control according to the action of embodiment 1.Wherein 3 triodes 16,16 ' and 16 " emitter grounding, collector connect respectively 3 relay coils 18,18 ' and 18 ", the positive source that this coil other end is connected to described singlechip controller 11 is (for example+6V).
Present embodiment is provided with a programming panel 12 and a display screen 13, electricity-saving appliance output voltage values and mode of operation (for example whether regularly changing output voltage etc.) that the user utilizes programming panel 12 to set to the single-chip microcomputer input.Programming panel 12 and display screen 13 all are the general-purpose devices that can purchase, and they are connected on the input and output mouth of single-chip microcomputer according to products instruction respectively.Other circuit is identical with embodiment 1 with principle, will not tire out at this and state.
Accompanying drawing 3 is the 3rd embodiment of the present invention.On the basis of Fig. 1, increased the low-voltage tap 50 of described autotransformer 1, and the main contacts 52 of contactor 51 is serially connected with between described tap 50 and the described lead-out terminal 5.The merely hit normally closed contact 71 of a relay 70 of the normally opened contact 61, of a time controller 60 of coil 53 serial connection of contactor 51 then is serially connected between described normally opened contact 82 and the input terminal 6.When described type voltage regulation reduction power saver is used for illumination and enters after midnight, described time controller 60 actions, normally opened contact 61 gets described coil 53, because the coil 72 of the described auxiliary reclay 70 of the auxiliary normally opened contact of contactor 51 54 serial connections constitutes handoff leg, this branch road is connected in parallel on again on the coil 53 of the contactor 51 that is connected with the low pressure tap, so just connect the coil 72 of described auxiliary reclay 70 after contactor 51 actions on earth, thereby the normally closed contact 71 that just utilizes described auxiliary reclay 70 cuts off the contactor 30 of working or the coil of contactor 40, finishes and do not have the switching to low-voltage of dodging outage.The power supply of pocket 60 is that alternating current 220V is attempted by between the terminal 6,7 when described.The other end of its normally opened contact also is connected on the terminal 6.The other parts and first embodiment are identical.At this, the circuit of comparer and voltage sample part omits, and will not tire out and state.
Figure 4 shows that a kind of new type voltage regulation reduction power saver that the present invention proposes.Principal feature is that described type voltage regulation reduction power saver is provided with a kind of new voltage-stabilizing controller, that is to say and be provided with the breaking circuit 25 that breaks away from power-saving running, its structure is isolating switch 26 of serial connection before described input terminal 6, its front end and one are called the main contacts 27 that disengages device 29 and join, and described main contacts 27 other ends link to each other with described lead-out terminal 5.Coil 28 serial connection one that disengages device 29 is merely hit and is parallel to the right side of described K switch behind the normally closed contact 36 of a relay 35 again, and the coil 37 of described auxiliary reclay 35 is connected in parallel between the terminal 6,7.When isolating switch 26 was connected, the normally closed contact 36 of described auxiliary reclay 35 disconnected because of coil 37 has electricity, and the described device 29 that disengages is not worked.When isolating switch 26 during because of the excessive disjunction of electric current, described disengage device 29 because of coil 28 electric work, the disjunction all of other contactor, this moment described autotransformer 1 dead electricity, input voltage is directly delivered on the lead-out terminal 5 through main contacts 27.Obviously, there is not Electronic Control in the breaking circuit 25, the safe escape when having guaranteed the energy-saving appliance accident.Hands off device 26 also can be realized this function.Other circuit and principle and embodiment three are identical, and circuit diagram is omitted, and will not tire out at this and state.Consider the ratio of performance to price, embodiment four is a most preferred embodiment.
