When the first breaker 1 and the second breaker 2 are all off-state, now the raised points T of driving wheel 7 is in commutation The position of switch 12.When total input power phase sequence is any different from the power input of A, B, C phase sequence device by A, C, B or other When, it is assumed that A, B, C phase sequence are correct phase sequence, then 1A, 1B, 1C terminal or second of the sequence judging circuit (2) from the first breaker 1 Breaker 2 2A, 2B, 2C terminal sampling come in power supply to sequence judging circuit (2) when, discovery phase sequence be it is wrong, now Voltage after from 1B terminals to diode D5 rectifications by resistance R6, resistance R7 to optocoupler U2 light emitting diode upper end when by Not right in phase sequence, the voltage-phase from the sampling of 1A terminals now is advanced or falls behind the voltage sampled with 1B terminals, electric current stream The process crossed is the electricity sampled from 1B terminals to diode D5 rectifications again to after resistance R6, the decompression of resistance R4 current limlitings, when any Quarter be not diode D5, diode D6 be in reverse blocking state be exactly triode Q2 be ahead of triode Q1 conducting, when three poles After pipe Q2 is turned on, the collection emitter-base bandgap grading conducting voltage 0.3V of triode Q2 now is triode Q1 transmitting junction voltages, so three All the time no electric current passes through the light emitting diode that pole pipe Q1 can not be in working condition, optocoupler U2 all the time, now optocoupler Phototriode in U2 does not work, and the emitter junction in triode Q3 is without conducting voltage, so low-tension current is at once from resistance R9 Relay K3 coils are arrived again to resistance R11 finally arrives ground.Now relay K3 adhesives, opened point originally is changed into normally off, Power taking in the L described from the above, executable portion after power taking after open phase relay group K1 and K2 phase shortage judge, Opened point becomes normally closed and arrives relay K3 again, is pressed by normally closed o'clock of relay K3 to the first SR 19 and the second reset The normally closed point of button 20, then to the normally closed point of the first limit switch 10, the operation winding L2 of single-phase actuating motor 5 is arrived after series capacitance Upper end, it is more advanced than starting winding L1 voltages due to now running winding L2, so now single-phase actuating motor 5 drives driving Wheel 7 is rotated counterclockwise, and drives first mechanical arm 8 to run downwards by trundle H1, due to alignment pin Z1 positioning action, first The other end of mechanical arm 8 is run up, while driving the handle 13 of the first breaker 1 to be moved to 0N positions.It is convex when driving wheel 7 Starting point T reaches the position of the first limit switch 10, withstands the button of the first limit switch 10, and the normally closed of the first limit switch 10 is touched Point disconnects, and the power supply of single-phase actuating motor 5 stops operating after being cut off, and now the handle 13 of the first breaker 1 is in 0N positions, First breaker 1 is closed, and the first relay indicating light 15 is lighted, and 14, the handle of the second breaker 2 is so in OFF, second Breaker 2 disconnects, and so far the device works.According to lead-out terminal 1D, 1E, 1F of the first breaker 1 and total output end R, S, T When annexation, even input power are inputted by A, C, B phase sequence of mistake, after the device correction, therefore the phase always exported Sequence or correct R, S, T-phase sequence.

2. there is phase sequence change when input power is sent a telegram here again after having a power failure in the device course of work, the device is adjusted automatically The action process of phase：

When input power is inputted by A, B, C phase sequence in the device course of work, it is assumed that A, B, C, phase sequence are correct phase sequence, Then the first breaker 1 is off, and the second breaker 2 is in closure state, if now having a power failure suddenly, when sending a telegram here again, Input power phase sequence does not change, and device phase sequence switching executing agency is failure to actuate, and the first breaker 1 is still in disconnection shape State, the second breaker 2 is still in closure state.It is different from if input power phase sequence changes by A, C, B or other are any It is normally opened from the executable portion after L power takings after open phase relay group K1 and K2 phase shortage judge when A, B, C phase sequence are inputted Point became normally closed and arrives relay K3 again, by normally closed o'clock of relay K3 to the first SR 19 and the second SR 20 Normally closed point, then to the normally closed point of the first limit switch 10, on the operation winding L2 of single-phase actuating motor 5 after series capacitance End, it is more advanced than starting winding L1 voltages due to now running winding L2, so now single-phase actuating motor 5 starts to turn counterclockwise Dynamic, driving wheel 7 drives second mechanical arm 9 to run up by trundle H2, due to alignment pin Z2 positioning action, the second machinery The other end of arm 9 is run downwards, while driving the handle 14 of the second breaker 2 to be moved to 0FF positions.The raised points T of driving wheel 7 When going to the position of reversing switch 12, the handle 14 of the second breaker 2 completely returns to 0FF positions, and the second breaker 2 disconnects.This When the first breaker 1 be also in OFF, driving wheel 7 continues to rotate counterclockwise, pass through trundle H1 drive first mechanical arm 8 Operation downwards, due to alignment pin Z1 positioning action, the other end of first mechanical arm 8 is run up, while driving the first open circuit The handle 13 of device 1 is moved to 0N positions.When the raised points T of driving wheel 7 reaches the position of the first limit switch 10, the first limit is withstood The button of bit switch 10, the normally-closed contact of the first limit switch 10 disconnects, and the power supply of single-phase actuating motor 5 stops turning after being cut off Dynamic, now the handle 13 of the first breaker 1 is in 0N positions, and the first breaker 1 is closed, and the first relay indicating light 15 is lighted, extremely This phase sequence trimming process is completed.Closed according to lead-out terminal 1D, 1E, 1F of the first breaker 1 and total output end R, S, T connection When system, even input power are inputted by A, C, B phase sequence of mistake, after the device correction, therefore the phase sequence always exported is still Correct R, S, T-phase sequence.

When input power is inputted by any A, B, C phase sequence that is different from of A, C, B or other of mistake in the device course of work When, the first breaker 1 is in closure state, and the second breaker 2 is off, if now having a power failure suddenly, when sending a telegram here again, Input power phase sequence does not change, and device phase sequence switching executing agency is failure to actuate.First breaker 1 is still in closed form State, the second breaker 2 is still in off-state.If input power phase sequence changes suddenly, according to correct A, B, C phase sequence During input, from L power takings, after the normally closed point K1 and K2 of the relay group that phase shortage judges to the first SR 19 normally closed point, Again to the normally closed point of normally closed point and limit switch 11 of the second SR 20, by reaching opening for single-phase actuating motor 5 after electric capacity C Dynamic winding L1 ends, now because power supplies of the startup winding L1 than running winding L2 of single-phase actuating motor 5 is advanced, so now single Phase actuating motor 5 starts to rotate clockwise, and driving wheel 7 drives first mechanical arm 8 to run up by trundle H1, due to positioning Z1 positioning action is sold, the other end of first mechanical arm 8 is run downwards, while driving the handle 13 of the first breaker 1 to 0FF Put movement.When the raised points T of driving wheel 7 goes to the position of reversing switch 12, the handle 13 of the first breaker 1 completely returns to 0FF Position, the first breaker 1 disconnects.Now the second breaker 2 is also in OFF, and driving wheel 7 continues to rotate clockwise, passed through Trundle H2 driving second mechanical arms 9 are run downwards, due to alignment pin Z2 positioning action, the other end of second mechanical arm 9 to Upper operation, while driving the handle 14 of the second breaker 2 to be moved to 0N positions.When the raised points T arrival second of driving wheel 7 is spacing The position of switch 11, withstands the button of the second limit switch 11, the normally-closed contact of the second limit switch 11 disconnects, single-phase to perform electricity The power supply of machine 5 stops operating after being cut off, and the handle 14 of the second breaker 2 is in 0N positions, and the second breaker 2 is closed, and second Relay indicating light 16 is lighted, and so far phase sequence trimming process is completed.According to lead-out terminal 2D, 2E, 2F of the second breaker 2 with it is total defeated Go out to hold R, S, T annexation, when input power is correct A, B, C phase sequence input, the phase sequence of output or correct R, S, T Phase sequence.

3. occurring under-voltage, phase shortage in the device course of work, the action process of the device is resetted during the failure such as output overcurrent：

When first breaker of device 1 is off, the second breaker 2 is in closure state, if input power is Inputted by correct A, B, C phase sequence, now the under-voltage, phase shortage of total input power appearance, the failure, the second breaker such as output overcurrent 2 can thread off at once, and the second relay indicating light 16 extinguishes.And switch due to phase sequence after the L power takings of executing agency's operating circuit part What is first passed around is the opened point that phase shortage judges relay, and the now power supply of single-phase actuating motor 5, which is cut off, is in halted state. Simultaneously phase shortage judges the normally closed point of the K1 and K2 of relay group simply by the presence of phase shortage phenomenon, from L to relay K1 and relay K2 After normally closed point, then after diode D11 rectifications to resistance R13 decompression after arrive phase shortage indicator lamp 17, now indicator lamp 17 is by point Bright, now the device non-transformer is exported.If excessively stream, thread off under conditions of, now due to dropout the second breaker 2 dropout Feedback point NO is closed, and passes through now closed NO by L, and acousto-optic report is arrived after being depressured current limliting through diode D14 dead resistances R16 Alert device 18, now trouble light 18 is lighted, and sends auditory tone cues, if now input power phase sequence changes, by A, C, B mistake Phase sequence input phase sequence switching executing agency when, the device pass through commutation function disconnect thread off the second breaker 2, closure first Breaker 1, realization automatically resets；If now input power phase sequence does not change, the device must hand-reset, reset Before, because nearly all mold cased circuit breaker is after dropout, to be closed next time, it is necessary to which first once disconnection is acted, It could be closed.After pending fault is excluded, the second SR 20 is pressed, a pair of opened points of the second SR 20 are closed, Loop on a pair of normally closed point disconnections, block system relay K4 and relay K3, does not power with single-phase actuating motor 5.Then pass through Relay group K1 and K2 that phase shortage judges, in the rear end power taking of relay K2 opened points, after the normally closed point of reversing switch 12 To the operation winding L2 of single-phase actuating motor 5, due to confessions of the operation winding L2 than starting winding L1 of now single-phase actuating motor 5 Electric advanced, so now single-phase actuating motor 5 starts to rotate counterclockwise, driving wheel 7 drives second mechanical arm 9 by trundle H2 Run up, due to alignment pin Z2 positioning action, the other end of second mechanical arm 9 is run downwards, while driving the second open circuit The handle 14 of device 2 is moved to 0FF positions.When the raised points T of driving wheel 7 goes to the position of reversing switch 12, reversing switch is withstood 12 button, normally closed point Y1, Y2 of reversing switch 12 disconnect, and the power supply of single-phase actuating motor 5 stops operating after being cut off, and second The handle 14 of breaker 2 completely returns to 0FF positions, and the second breaker 2 completes to reset.Now the first breaker 1, the second breaker 2 are at off-state.Because the dropout feedback point NO on the first breaker 2 reverts to opened point again, audible-visual annunciator 18 Power supply is disconnected, and is now stopped, do not sending the sound and light signal of alarm.

Unclamp after the second SR 20, because second on the loop that phase sequence switches executing agency's operating circuit resets Two normally closed points of button 20 become closure state again, so according to now being judged by sequence judging circuit (2).Relay To after the normally closed point of the first SR 19 after K4 adhesives, opened point closure, then to the normally closed point and limit of the second SR 20 The normally closed point of bit switch 11, by reaching the startup winding L1 ends of single-phase actuating motor 5 after electric capacity C, now performs electricity due to single-phase Power supplies of the startup winding L1 of machine 5 than running winding L2 is advanced, so single-phase actuating motor 5 starts to rotate clockwise, driving wheel 7 It is changed into rotating clockwise, drives second mechanical arm 9 to run downwards by trundle H2, due to alignment pin Z2 positioning action, the The other end of two mechanical arms 9 is run up, while driving the handle 14 of the second breaker 2 to be moved to 0N positions.When driving wheel 7 Raised points T reaches the position of the first limit switch 10, and the handle 14 of the second breaker 2 is in 0N positions, and the second breaker 2 is closed Close, the second relay indicating light 16 is lighted.When the raised points T of driving wheel 7 goes to the position of the second limit switch 11, the first limit is withstood The button of bit switch 11, the normally-closed contact of the second limit switch 11 disconnects, and the power supply of single-phase actuating motor 5 stops turning after being cut off Dynamic, the second relay indicating light 16 is lighted, and the device recovers normal work again.

When first breaker of device 1 is in closure state, the second breaker 2 is off, now input power Be by mistake A, C, B phase sequence or it is other it is any inputted different from A, B, C phase sequence, if now total input power appearance it is under-voltage, Phase shortage, during the failure such as output overcurrent, the first breaker 1 can thread off at once, and the first relay indicating light 15 extinguishes.And because commutation is held What is first passed around after the L power takings of row part is the disconnected opened point for mutually judging relay, and the now power supply of single-phase actuating motor 5 is cut It is disconnected to be in halted state.The simultaneously disconnected normally closed point of K1 and K2 for mutually judging relay group simply by the presence of disconnected phase phenomenon, from L to phase shortage after After electrical equipment group K1 and K2 normally closed point after diode D11 rectifications, phase shortage indicator lamp 17 is arrived again to resistance R13 decompressions, now Phase shortage indicator lamp 17 is lit, and so far the device non-transformer is exported.If under conditions of excessively stream, dropout, due to the first of dropout The dropout feedback point NO closures of breaker 1, pass through now closed NO by L, are depressured through diode D14 rectifications, resistance R16 Audible-visual annunciator 18 is arrived after current limliting, now 18 is lit, and send auditory tone cues；If now input power phase sequence changes, When inputting the device by A, B, C, correct phase sequence, the device disconnects the first breaker 1 threaded off, closure the by commutation function Two breakers 2, realization automatically resets.If now input power phase sequence does not change, the device must hand-reset, reset Before, because nearly all mold cased circuit breaker is after dropout, to be closed next time, it is necessary to which first once disconnection is acted, It could be closed.After pending fault is excluded, the first SR 19 is pressed, a pair of opened points of the first SR 19 are closed, Loop on a pair of normally closed point disconnections, block system relay K4 and relay K3, does not power with single-phase actuating motor 5.From by lacking The relay group K1 and K2 mutually judged, in the lower end power taking of relay K2 opened points, is arrived after the normally closed point of reversing switch 12 The startup winding L1 of single-phase actuating motor 5, due to now power be single-phase actuating motor 5 startup winding L1 than operation winding L2 power supply is advanced, so now single-phase actuating motor 5 starts to rotate clockwise, driving wheel 7 drives first by trundle H1 Mechanical arm 8 is run up, due to alignment pin Z1 positioning action, and the other end of first mechanical arm 8 is run downwards, while driving the The handle 13 of one breaker 1 is moved to 0FF positions.When the raised points T of driving wheel 7 goes to the position of reversing switch 12, withstand and change To the button of switch 12, normally closed point C, D of reversing switch 12 disconnect, and the power supply of single-phase actuating motor 5 stops operating after being cut off, The handle 13 of first breaker 1 completely returns to 0FF positions, and the first breaker 1 completes to reset.Now the first breaker 1, second breaks Road device 2 is at off-state.Because the dropout feedback point NO on the first breaker 1 reverts to opened point, audible-visual annunciator again 18 power supply is disconnected, and is stopped, and is not sending sound and light signal.

Unclamp after the first SR 19, due to the SR on the loop that phase sequence switches executing agency's operating circuit 19 two normally closed points become closure state again, so according to now being judged by sequence judging circuit (2), relay K3 inhales Close, to after the normally closed point of the first SR 19 after opened point closure, then to the second SR 20 normally closed point and spacing open 10 normally closed points are closed, by reaching the operation winding L2 ends of single-phase actuating motor 5 after electric capacity C, now due to single-phase actuating motor 5 Run winding L2 more advanced than startup winding L1 power supply, similar to reseting procedure, driving wheel 7 continues to rotate counterclockwise, and passes through and passes Dynamic pin H1 driving first mechanical arms 8 are run downwards, and due to alignment pin Z1 positioning action, the other end of first mechanical arm 8 is upward Operation, while driving the handle 13 of the first breaker 1 to be moved to 0N positions.Opened when the raised points T arrival second of driving wheel 7 is spacing The position of pass 10, the handle 13 of the first breaker 1 is in 0N positions, and the first breaker 1 is closed, the first 15 points of relay indicating light It is bright.When the raised points T of driving wheel 7 goes to the position of the first limit switch 10, the button of the first limit switch 11, the first limit are withstood The normally-closed contact of bit switch 10 disconnects, and the power supply of single-phase actuating motor 5 stops operating after being cut off, and the device recovers normal work again Make.

When input power is inputted by A, B, C phase sequence in the device course of work, it is assumed that A, B, C phase sequence are correct phase sequence, Then the first breaker 1 is off, and the second breaker 2 is in closure state, if now having a power failure suddenly, when sending a telegram here again, Input power phase sequence does not change, and device phase sequence switching executing agency is failure to actuate, and the first breaker 1 is still in disconnection shape State, the second breaker 2 is still in closure state.It is different from if input power phase sequence changes by A, C, B or other are any When A, B, C phase sequence are inputted, time-delay relay KT coil is after C' power takings in phase sequence switching executing agency operating circuit, delay Relay adhesive, three pairs of opened points closure, the closed opened point of the power supply come in from A ＇, C ＇, B ＇ power takings, then to normally closed heat after Output end of the input of electrical equipment through electrothermal relay, finally to three-phase actuating motor 6, because the power supply now inputted is wrong Phase sequence, so three-phase actuating motor 6 is rotated counterclockwise, driving wheel 7 drives first mechanical arm 8 to run downwards by trundle H1, Due to alignment pin Z1 positioning action, the other end of first mechanical arm 8 is run up, while driving the handle of the first breaker 1 13 move to 0N positions.When the raised points T of driving wheel 7 reaches the position of the second limited post 4, the handle 13 of the first breaker 1 In 0N positions, while the handle 14 of the second breaker 2 is in 0FF positions.First breaker 1 is closed, and the second breaker 2 breaks Open.First relay indicating light 15 is lighted.The raised points T of driving wheel 7 withstands the second limited post 4, and driving wheel stops operating, and works as delay Relay is set after time arrival, and time-delay relay disconnects, and the power supply of three-phase actuating motor 6 is cut off, and three-phase actuating motor stops Rotation stop is moved.According to output end 1D, 1E, 1F of the first breaker 1 and total output end R, S, T annexation, electricity is even inputted When source is inputted by A, C, B phase sequence of mistake, after the device correction, therefore the phase sequence always exported or correct R, S, T-phase sequence.

When input power presses A, C, B phase sequence or other any different from A, B, C phase sequence of mistake in the device course of work During input, the first breaker 1 is in closure state, and the second breaker 2 is off, if now having a power failure suddenly, comes again When electric, input power phase sequence does not change, and device phase sequence switching executing agency is failure to actuate.First breaker 1 is still in closing Conjunction state, the second breaker 2 is still in off-state.If input power phase sequence changes suddenly, according to correct A, B, C When phase sequence is inputted, time-delay relay KT coil is after C' power takings in phase sequence switching executing agency operating circuit, and be delayed relay Device adhesive, three pairs of opened points closure, the closed opened point of the power supply come in from A ＇, B ＇, C ＇ power takings, then to normally closed electrothermal relay Input, the output end through electrothermal relay finally arrives three-phase actuating motor 6, because the power supply now inputted is correct phase sequence, So three-phase actuating motor 6 is rotated clockwise, driving wheel 7 is run downwards by trundle H2, driving second mechanical arm 9, due to Alignment pin Z2 positioning action, the other end of second mechanical arm 9 is run up, at the same drive the second breaker 2 handle 14 to Move 0N positions.When the raised points T of driving wheel 7 reaches the position of the first limited post 3, the handle 14 of the second breaker 2 is in 0N positions, while the handle 13 of the first breaker 1 is in 0FF positions, the first breaker 1 is disconnected, and the second breaker 2 is closed, the One relay indicating light 15 is lighted.The raised points T of driving wheel 7 withstands the first limited post 3, and driving wheel stops operating, when delay relay Device is set after time arrival, and time-delay relay disconnects, and the power supply of three-phase actuating motor 6 is cut off, and three-phase actuating motor stops turning It is dynamic.According to lead-out terminal 2D, 2E, 2F and the device total output end R, S, T of the second breaker 2 annexation, input power When being correct A, B, C phase sequence input, the phase sequence of device output or correct R, S, T-phase sequence.

When first breaker of device 1 is off, the second breaker 2 is in closure state, now input power It is to be inputted by correct A, B, C phase sequence, if the now under-voltage, phase shortage of total input power appearance, during the failure such as output overcurrent, second Breaker 2 can thread off at once, and the first relay indicating light 15 extinguishes, now due to dropout the first breaker 1 dropout feedback point NO is closed, and passes through now closed NO by L, and audible-visual annunciator 18 is arrived after being depressured current limliting through diode D2 rectifications, resistance R2, Now audible-visual annunciator 18 is lighted, and sends sound and light alarm.Pending fault is disposed, when the device restarts, if now defeated Enter power phase to change, when switching executing agency by the phase sequence input phase sequence of A, C, B mistake, the device passes through commutation function The second breaker 2 of de- mouth is disconnected, the first breaker 1 is closed, realization automatically resets；If now input power phase sequence does not occur Change, the necessary hand-reset of the device, before reset, the necessary first once disconnection action of the second breaker 2 of dropout is (because almost All mold cased circuit breakers are after dropout, to be closed next time, it is necessary to which first once disconnection is acted, and could be closed Close).Now press the first SR 19, one group of two normal open switch with linkage of the first SR 19, to hot relay The normally closed point of device, then to three-phase actuating motor 6, because now because the power supply sampled into is changed by the first SR 19 Phase sequence is crossed, is changed into A, C, B phase sequence of mistake, or it is other any different from A, B, C phase sequence, so now three-phase actuating motor 6 Rotate counterclockwise.Driving wheel 7 drives second mechanical arm 9 to run up by trundle H2, due to alignment pin Z2 positioning action, The other end of second mechanical arm 9 is run downwards, while driving the handle 14 of the second breaker 2 to be moved to 0FF positions.Driving wheel 7 Raised points T when going to the position of reversing switch 12 and withstanding the button of reversing switch 12, the handle 14 of the second breaker 2 is returned completely To 0FF positions, the second breaker 2 is gone off by dropout.The normally closed point of reversing switch 12 disconnects, the confession of three-phase actuating motor 6 Electricity is cut off, and three-phase actuating motor stops operating.Now the handle 13 of the first breaker 1 is yet in 0FF positions, two open circuits Device is all in off-state, and because the dropout feedback point NO of the second breaker 2 reverts to opened point again, audible-visual annunciator 18 stops Work.

When decontroling SR 19, if now total input power is still inputted with the correct phase sequence of A, B, C, cut in phase sequence The coil of time-delay relay KT in executing agency's operating circuit is changed after C' power takings, time-delay relay adhesive, three pairs of opened points are closed Close, the closed opened point of the power supply come in from A ＇, B ＇, C ＇ power takings, then to the input of normally closed electrothermal relay, most afterwards through heat after The output end of electrical equipment is to three-phase actuating motor 6, because the power supply now inputted is correct phase sequence, three-phase actuating motor 6 Rotate clockwise, driving wheel 7 drives second mechanical arm 9 to run downwards by trundle H2, due to alignment pin Z2 positioning action, The other end of second mechanical arm 9 is run up, while driving the handle 14 of the second breaker 2 to be moved to 0N positions.When driving wheel 7 Raised points T when reaching the position of the first limited post 3, the handle 14 of the second breaker 2 is in 0N positions, and the second breaker 2 is closed Close, the first relay indicating light 15 is lighted.The raised points T of driving wheel 7 withstands the first limited post 3, and driving wheel stops operating, and works as delay Relay is set after time arrival, and time-delay relay disconnects, and the power supply of three-phase actuating motor 6 is cut off, and three-phase actuating motor 6 stops Rotation stop is moved, and so far the device recovers normal work again.According to the total of lead-out terminal 2D, 2E, 2F of the second breaker 2 and the device Output end R, S, T annexation, when input power is the input of correct A, B, C phase sequence, the phase sequence of device output is still just True R, S, T-phase sequence.

When first breaker of device 1 is in closure state, the second breaker 2 is off, now input power Be by mistake A, C, B phase sequence or it is other it is any inputted different from A, B, C phase sequence, if now total input power appearance it is under-voltage, Phase shortage, during the failure such as output overcurrent, the first breaker 1 can thread off at once, and the first relay indicating light 15 extinguishes, now due to threading off The first breaker 1 dropout feedback point NO closure, by L pass through now closed NO, through diode D2 rectifications, resistance R2 It is depressured after current limliting and arrives audible-visual annunciator 18, now audible-visual annunciator 18 is lighted, and sends sound and light alarm.Pending fault is disposed, ,, should when inputting the device by the correct phase sequence of A, B, C if now input power phase sequence changes when the device restarts Device disconnects the first breaker 1 threaded off by commutation function, closes the second breaker 2, realization automatically resets.If now inputting Power phase does not change, the necessary hand-reset of the device, before reset, and the first breaker 1 of dropout must first once Disconnection action is (because nearly all mold cased circuit breaker is after dropout, to be closed next time, it is necessary to first once disconnect Action, could be closed).The first SR 19 is now pressed, one group of the first SR 19 is normal with two linked Normally closed point through electrothermal relay is switched to electrothermal relay, finally to three-phase actuating motor 6, because now due to sampling into Electricity is to be accordingly changed into correct A, B, C phase sequence by what the first SR 19 changed phase sequence, so now three-phase actuating motor 6 is suitable Hour hands are rotated.Driving wheel 7 drives first mechanical arm 8 to run up by trundle H1, due to alignment pin Z1 positioning action, the The other end of one mechanical arm 8 is run downwards, while driving the handle 13 of the first breaker 1 to be moved to 0FF positions.Driving wheel 7 When the button of reversing switch 12 is withstood in the position that raised points T goes to reversing switch 12, the handle 13 of the first breaker 1 is completely returned to 0FF positions, the first breaker 1 is gone off by dropout.The normally closed point of reversing switch 12 disconnects, the power supply of three-phase actuating motor 6 It is cut off, three-phase actuating motor stops operating.Now the handle 14 of the second breaker 2 is yet in 0FF positions, two breakers All in off-state, because the dropout feedback point NO of the first breaker 1 reverts to opened point again, audible-visual annunciator 18 stops work Make.

When decontroling the first SR 19, because now total input power is A, C, B or other any different from A, B, C Phase sequence, time-delay relay KT coil is after C' power takings in phase sequence switching executing agency operating circuit, time-delay relay adhesive, Three pairs of opened points closure, the closed opened point of the power supply come in from A ＇, B ＇, C ＇ power takings, then to the defeated of normally closed electrothermal relay KH Enter end, the output end through electrothermal relay KH is to three-phase actuating motor 6, because the power supply now inputted is the phase sequence of mistake, Three-phase actuating motor 6 is rotated counterclockwise, and driving wheel 7 drives first mechanical arm 8 to run downwards by trundle H1, due to alignment pin Z1 positioning action, the other end of first mechanical arm 8 is run up, while driving the handle 13 of the first breaker 1 to 0N positions It is mobile.When the raised points T of driving wheel 7 reaches the position of the second limited post 4, the handle 13 of the first breaker 1 is in 0N positions, First breaker 1 is closed, and the first relay indicating light 15 is lighted.The raised points T of driving wheel 7 withstands the second limited post 4, and driving wheel stops Rotation stop is moved, and after time-delay relay sets the time to reach, time-delay relay is disconnected, and the power supply of three-phase actuating motor 6 is cut off, and three Phase actuating motor stops operating, and so far the device recovers normal work again.According to lead-out terminal 1D, 1E, 1F of the first breaker 1 With total output end R, S, T of the device annexation, even input power by mistake A, C, B phase sequence input when, through this After device correction, therefore the phase sequence of total output of the device or correct R, S, T-phase sequence.
