circuit of contactor energy-saving (DB module) 015 end L ', relay J3 5 foot connection of contact, while the end L ' passes through the L ' of a normally closed auxiliary contact of institute's control contactor The both ends J2 are connected to the public translation end of relay J2, (if in application this product, the end Li ' not connection institute control contactor One normally closed auxiliary contact, " electronics electric control failure self-closing and alarm peripheral circuit " would not have an effect.In this case, This circuit 017 is equivalent to a kind of anti-shake application of electric controller circuit 015 of contactor energy-saving.Miniature direct current relay J2's is normally closed The conversion contact end of contact J2-1 relay termination J4, the positive terminal of the normally closed interlock terminating diode D12 of relay J4, two poles The T1 foot of the cathode termination bidirectional triode thyristor KG1 of pipe D12, one end of

contactor energy-saving correspond to connection；12 foot of contact of J3 connects A1 output end, 9 foot of J3 contact connect A2 output end, simultaneously with 13 foot node connection of J3 contact.The function of circuit 017 is: once DB 015 circuit operational failure of module, the fast starting that cannot complete contactor are attracted, and at this moment the circuit passes through during 1-3 seconds Be delayed attracting electric relay J3 transformation, and the contactor that DB module 015 controls is transformed into directly controlling for 220VAC, is connect simultaneously Tentaculum is detached from the control of DB module 015, to guarantee the uninterrupted power supply to load.It is simultaneously emitted by alarm, to prompt user Pay attention to.One kind has the contactor energy-saving of electronic control (DB module) failure self-closing and warning function peripheral circuit anti-shake automatically controlled Circuit 017 processed is by battery main switch K, and (input termination power supply source L, N-terminal, output end are named as the end L ', N ') and one kind connect The anti-shake electric controller circuit (DB module) 015 of tentaculum energy conservation and one kind have electronics electric control (DB module) failure self-closing and report Alert function peripheral circuit common combination forms.The course of work is as follows: when L, N input terminal connect 220VAC alternating current and connect switch K When, the anti-shake electric controller circuit of contactor energy-saving (DB module) 015 quick starts in 10ms is attracted contactor, makes to be controlled immediately The both ends normally opened auxiliary contact No1, No2 of the one of contactor processed are connected, and automatically keep contactor under the control of DB modular circuit 015 Continue sticking energy conservation state.Another normally closed auxiliary contact L ' of contactor, the both ends J2 disconnect simultaneously, and cutting L ' give relay The power supply of J2 normally closed interlock, in this way, " electronic control (DB module) failure self-closing and warning function peripheral circuit " is because obtain not It stops working to power supply, therefore peripheral circuit does not play a role.Job analysis is as follows: due to the anti-shake electricity of contactor energy-saving Controller circuitry 015(DB module) characteristic of contactor is attracted with fast starting in 10ms, and " electronic control (DB module) is lost There is J3 relay in effect self-closing and peripheral circuit of alarming " starting of delay 1-3s to be attracted characteristic, so this product is connecing Power supply moment, it is anti-shake that " electronics electric control (DB module) failure self-closing and alarm peripheral circuit " not will cause docking tentaculum energy conservation The work influence of electric controller circuit (DB module) 015.Only in the anti-shake electric controller circuit 015(DB module of contactor energy-saving) Following failure occur: DB module 015 does not have fast start up characteristics, or because failure, which cannot be guaranteed to start in 10MS, is attracted institute A.C. contactor is controlled, or cannot guarantee that contactor starts attracting state for a long time, then, " electronic control (DB module) failure is certainly Connection and alarm peripheral circuit " just enters working condition, and the course of work is as follows: as power supply voltage≤80%Us, passing through The method for selecting varistor RY1 parameter, realizing " has electronic control (DB module) failure self-closing and warning function periphery electricity The anti-shake electric control circuit 017 " of the contactor energy-saving on road be in can not working condition, that is, do not have start sticking function；Work as power supply When supply voltage > 80%Us, if " the anti-shake electric control circuit 015(DB module of contactor energy-saving) " the fail to start suction in 10MS It closes, the normally closed auxiliary contact L ' of contactor, the both ends J2 also keep original on-state → end L ' voltage to pass through contactor at this time Normally closed auxiliary contact L ', the both ends J2 → pass through relay J2 normally-closed contact J2-1 → relay J4 normally-closed contact J4-1 → diode D12 → bidirectional triode thyristor triggering knot the both ends the T1-Gl → varistor RY1 → end resistance R47 and N ' forming circuit → to trigger Bidirectional triode thyristor KG1 conducting → supply voltage L is normal by a normally closed auxiliary contact L ', the both ends the J2 → relay J2 of contactor Closed contact J2-1 → relay J4 normally-closed contact J4-1 → diode D12 → the both ends bidirectional triode thyristor T1-T2 → PTC1 temperature-sensitive electricity Resistance → to capacitor C19 quick charge → when the charging voltage of capacitor C19 quickly reaches the starting voltage of relay J2 → relay Device J2 starts the actuation → contact J2-1 disconnection → contact J2-2 connection → end L ' voltage and passes through the normally closed auxiliary touching of institute's control contactor Point L ', the both ends J2 → between contact J2-2 of low voltage DC relay J2 → are applied to 13 end of J3 coil → by J3 relay line Circle starts 12 end of actuation → J3 conversion contact from original with the end power supply N ' forming circuit → time delay starting relay J3 in 1-3S That comes leads to logical be transformed into of 1 termination with 5 terminations with logical 9 end of conversion contact for terminating logical → J3 with 8 that is transformed into of 4 terminations from original → realize the continuous power supply of time-delay relay J3 coil.Due at this moment supply voltage L ', N ' directly with the coil KM of contactor A1, A2 termination it is logical, so, ensure that A.C. contactor starts the uninterrupted turn-on power loss being attracted.At this moment, supply voltage L ' is gone back By the 5 of J3,9 end connection, continues through high-voltage capacitance C20 and exchanged with the parallel branch of resistance R46 to the one of rectifier ZL-3 Supplying power for input end, another ac input end of rectifier ZL-3 are directly connected to the end power supply N ', and the low-voltage direct of rectifier ZL-3 is defeated It ensure that the continuous power supply of Miniature direct current relay J2 coil holding voltage out, while ensure that the friendship of exchange time-delay relay J3 Flow powered operation state.Buzzer Y1 prompts the anti-shake electric control of user's contactor energy-saving because obtaining electric sending alarm under this state Device circuit 015(DB module) it breaks down.The parameter selection of varistor RY1 is can guarantee only in supply voltage Us > When 180VAC, bidirectional triode thyristor KG1 conducting can be just triggered, to meet the requirement of A.C. contactor reliably started.High pressure The foundation of the selection of capacitor C20 capacity is to meet the release of the release voltage and controlled A.C. contactor of relay J2 as far as possible The needs of voltage consistency guarantee the reliability of A.C. contactor work；PTC1 plays the work of limitation relay J2 starting current With.After DC relay J2 starts actuation, because having cut off the relay being made of diode D12, bidirectional triode thyristor KG1, PTC1 Device J2 starts the power supply between branch L ' and N ', therefore the starting branch stops working, and at this moment the power supply of L ', N ' pass through capacitor C20, resistance R46 parallel branch are applied to the ac input end of full bridge rectifier ZL-3, provide direct current holding voltage for J2 is logical. If making a normally closed auxiliary contact end of the end L ' not connection institute control contactor in application this product, " electronic control failure Self-closing and alarm peripheral circuit " would not have an effect, and it is anti-shake automatically controlled to be equivalent to a kind of contactor energy-saving in this case Device circuit 015(DB module processed) application.If " mobile phone client module Integrated circuit IC 6 " issues shutdown command → 013 electricity Road "+" end generates positive electricity piezoelectric position → 06 circuit Q9 conducting → Q10 and carries only → holding voltage output VD1=0 → A.C. contactor Coil unpowered, while the switching circuit work being made of the triode Q22, capacitor C22, resistance R54 of VD3 uninterrupted power supply → The starting branch of relay J2 normally closed interlock control is cut in triode Q17 conducting → relay J4 actuation → J4 normally closed interlock disconnects → → relay J2, J3 do not work；Simultaneously as "+" end has positive voltage high potential → VD1=0 → to lead to circuit 05,06,07,08 It stops working, complete machine is caused to stop working.Conversely, "+" end zero potential, complete machine is worked normally.
As shown in figure 18, a kind of that there is electronic control (DB module) failure self-closing and the contact of warning function peripheral circuit A kind of common wiring pattern block diagram 018 when device energy conservation anti-shake electric control circuit 017 application；L, N-terminal is its power input, L ', J2 terminates the both ends of the normally closed auxiliary contact of institute's control contactor one, and N01, N02 terminate the normally opened auxiliary contact of institute's control contactor one Both ends, A1, A2, which are terminated, connects loop A 1, the end A2 of tentaculum.
As shown in figure 19, another kind when a kind of anti-shake electric controller circuit 017 of (modified) contactor energy-saving is applied connects Line block diagram circuit 019 connects together the output end A1, A2 of circuit 017 and the end A1, A2 of A.C. contactor, is shorted simultaneously The both ends N01, N02 power on master switch K, using L, N input terminal of circuit 017 as the input terminal of control voltage Us, while Power input concatenation controlled A.C. contactor normally-open normally-close auxiliary contact and start button as shown in the figure；L ', the both ends J2 Connect another normally closed auxiliary contact both ends of controlled A.C. contactor.The advantages of the method is mode of connection and A.C. contactor Traditional wired method it is identical.
As shown in figure 3, the pulsewidth modulation DC-DC conversion circuit 03 with operating voltage section automatic function selecting is It is defeated by high frequency switch transformer Ta, capacitor C1, C2, C3, resistance R0, R1-R5, high frequency power triode G1, Width funtion, invariable power Control circuit 02 and Xiao Jite rectifier diode D3 composition out, the pulsewidth tune with operating voltage section automatic function selecting DC-DC conversion circuit 03 processed is by with the arteries and veins after the full-bridge rectifier ZL-1 of short-circuit protection function total pressure rectification circuit 01 rectification The full voltage DC-AC two-use that dynamic direct current full voltage or direct current input inputs this circuit by the end VA and Da, and the VA positive voltage of input is logical Cross one end of overcurrent protection resistance R0 and pliotron G1 upper inclined resistance R1, I Same Name of Ends of primary coil of switch transformer Ta The end P1 is connected；The collector of the inverse name end P2 termination triode G1 of primary coil I, the end P1 and P2 is parallel with resistance R3；Power three The base stage of pole pipe G1, the lower end upper inclined resistance R1, the upper end of lower inclined resistance R2, positive feedback resistor R5 one end be same node；Together When the node connect with the end G1-b of Width funtion, constant power output control circuit 02, the end lower termination Da of lower inclined resistance R2；Resistance The other end of R5 is connected with one end of positive feedback capacitor C1, the end Same Name of Ends P3 of another terminated line circle II of positive feedback capacitor C1, together When the end P3 be also switch transformer Ta primary coil II 02 circuit of the end P3 and constant power output control circuit the end P3, the end P4 It is simultaneously also the inverse name end end P4 of the primary coil II of switch transformer Ta, the end P4 connects Width funtion, constant power output control again The emitter at the end P4 of circuit 02, pliotron G1 connects the end Da, emitter current negative-feedback electricity by Current Negative Three-Point Capacitance resistance R4 Hinder the upper end R4, that is, high frequency oscillation pliotron G1Emitter, the emitter simultaneously also with Width funtion, constant power output control The end G1-e of circuit 02 is connected, the P5 Same Name of Ends of the secondary coil III of switch transformer Ta and the P6 Same Name of Ends of secondary coil IV The cathode of Xiao Jite diode D3 is connect, the anode of Xiao Jite diode D3 meets GND, and the inverse name end P8 of secondary coil III terminates filtering The anode of capacitor C2, the negative terminal of C2 meet GND, and the high-frequency pulse voltage of the inverse name end end the P8 output of secondary coil III passes through capacitor C2 Filtering becomes direct-flow positive voltage, is exactly applied to V1 positive voltage needed for 04 circuit or applied to V2 positive electricity needed for 012 circuit Pressure；The high-frequency pulse voltage of the inverse name end end the P7 output of secondary coil IV becomes direct-flow positive voltage V3 by capacitor C3 filtering.Tool There is the pulsewidth modulation DC-DC conversion circuit 03 of automatic work voltage range selection function, passes through switch transformer Ta primary coil I Electric current be exactly triode G1 collector current；When input direct-current voltage V1 passes through protective resistance R0, switch transformer Ta's Primary coil I adds to the collector of triode G1, while when by the base stage of the upper inclined resistance R1 G1 added to, three pole of power switch Pipe G1 conducting, P of the collector current from the primary coil I of switch transformer Ta1End flows to P2End, according to the law of electromagnetic induction: line The P1 Same Name of Ends of circle I induces upper just lower negative with respect to its different name end end P2, the Same Name of Ends P3 of coil II with respect to its different name end end P4 Voltage, then positive feedback occur: P3 rectify voltage pass through capacitor C1The work shape of the base stage of G1 → make G1 is added to resistance R5 State enters saturation state → with capacitor C from magnifying state rapidly1Charging current reduce, pliotron G1Working condition After returning to amplification region from saturation region again, collector current becomes reduction state from growth state, then switch transformer Ta line Circle I and II both ends induced voltage of coil mutate, and induce voltage positive under bearing, this mutation backward voltage moment passes through electricity Hold the base stage that C1 and resistance R5 adds to triode G1, makes triode G1Base stage it is reverse-biased, to make triode G1Cut-off；Then electric Hold C1 and enter positive charge again, with capacitor C1Positive charge, the base potential of power switch tube G1 increases again, Triode G1 enters again from off state is amplified to saturated, and then, above-mentioned positive feedback process occurs again, with regard to this Sample, power switch tube G1The electric energy high speed of power supply is converted into switch transformation by continuous on and off iterative cycles work The magnetic energy of device

capacitor and load in the magnetic energy being stored in switch transformer Ta.Due to conversion Frequency is very high, therefore the volume of switch transformer is 1/5th of Industrial Frequency Transformer or so.Automatically determine operating voltage section The realization of function, what is leaned on is the reasonable static working current for determining power switch tube G1 to realize.With automatic work voltage The pulsewidth modulation DC-DC conversion circuit 03 of interval selection function realizes that Width funtion, the working principle of constant power output are as follows: working as control When voltage Us processed is supplied to (25%-130%) Us voltage between this circuit input end V1 and Da, pass through Width funtion, constant power output The working principle of control circuit 02 realizes the pressure stabilizing output characteristics of this Switching Power Supply.Design is at input voltage (25%-130%) The universe range of Us, the voltage of
