In the time that the first circuit breaker 1 and the second circuit breaker 2 are all off-state, now the raised points T of driving wheel 7 is in the position of reversing switch 12.When total input power phase sequence is correct A, B, when the input of C phase sequence, sequence judging circuit (2) is from the 1A of the first circuit breaker 1, 1B, the 2A of 1C terminal or the second circuit breaker 2, 2B, the sampling of 2C terminal, circuit breaker 1B terminal or 2B terminal through diode D5 rectification again through resistance R 6, after resistance R 7 step-down current limlitings, arrive the anode tap of optocoupler U2 light-emitting diode, because now phase sequence is correct, so the electricity of sampling from the 1A terminal of circuit breaker is to capacitor C 5, resistance R 6, direct current through resistance R 4 has the above voltage of 0.7V to the triode Q1 base terminal of NPN type, so now triode Q1 conducting, the lumination of light emitting diode of optocoupler U2 inside, U2 work, now by power supply voltage stabilizing part (1) circuit through the power taking of circuit breaker 1C terminal to insurance FU again to after capacitor C 1 filtering to transformer T1 step-down, by diode D1, diode D2, diode D3, the bridge rectifier of diode D4 composition is rectified into the direct voltage of pulsation, again by capacitor C 2, capacitor C 3 is filtered into a certain degree galvanic current and presses, carry out further step-down by three-terminal voltage-stabilizing chip U1 again, voltage stabilizing, after excessive DC electrolysis capacitor C 4 filtering, output to judging phase order result output (3), from power unit obtains low pressure galvanic current, because the light-emitting diode of optocoupler U2 inside is conducting state, the isolation output photoelectric triode conducting of optocoupler U2 inside, after the current limliting of resistance R 10, arrive the base stage of triode Q3, now triode Q3 conducting, the collector electrode of triode Q3 has electric current to pass through, relay K 4 adhesives.When after relay K 4 adhesives, become normally closed point normal battle originally, power taking in the L being narrated from the above, through normally closed some K1 of the relay group of phase shortage judgement and K2 after the normally closed point of the first reset button 19, again to normally closed point and the normally closed point of limit switch 11 of the second reset button 20, by arriving startup winding L 1 end of single-phase actuating motor 5 after capacitor C, now because the startup winding L 1 of single-phase actuating motor 5 is more leading than the power supply of operation winding L 2, so now single-phase actuating motor 5 starts to clockwise rotate, driving wheel 7 clockwise rotates, drive the second mechanical arm 9 to move downwards by trundle H2, due to the positioning action of alignment pin Z2, the other end of the second mechanical arm 9 upwards moves, drive the handle 14 of the second circuit breaker 2 to move to 0N position simultaneously.When the raised points T of driving wheel 7 arrives the position of the second limit switch 11, withstand the button of the second limit switch 11, the normally-closed contact of the second limit switch 11 disconnects, and after the power supply of single-phase actuating motor 5 is cut off, stops operating.Now the handle 14 of the second circuit breaker 2 is in 0N position, the second circuit breaker 2 closures, and the second relay indicating light 16 is lighted; 13, the handle of the first circuit breaker 1 is so in OFF position, and the first circuit breaker 1 is in disconnection, so far this device work.According to the annexation of lead-out terminal 2D, the 2E of the second circuit breaker 2,2F and total output R, S, T, when input power is correct A, B, the input of C phase sequence, the phase sequence of output or correct R, S, T phase sequence.

In the time that the first circuit breaker 1 and the second circuit breaker 2 are all off-state, now the raised points T of driving wheel 7 is in the position of reversing switch 12.When total input power phase sequence is pressed A, C, B or other any A that is different from, B, when the power supply of C phase sequence is inputted this device, suppose A, B, C phase sequence is correct phase sequence, sequence judging circuit (2) is from the 1A of the first circuit breaker 1, 1B, the 2A of 1C terminal or the second circuit breaker 2, 2B, the power supply that 2C terminal is sampled is into during to sequence judging circuit (2), find that phase sequence is wrong, voltage now from 1B terminal to diode D5 rectification is through resistance R 6, resistance R 7 during to the upper end of the light-emitting diode of optocoupler U2 because phase sequence is not right, the voltage leading or backward and that 1B terminal is sampled of the voltage-phase from the sampling of 1A terminal now, the process that electric current flows through be electricity from 1B terminal sampling to diode D5 rectification again to resistance R 6, after resistance R 4 current limliting step-downs, not diode D5 at any time, it is exactly that triode Q2 is ahead of triode Q1 conducting that diode D6 is in reverse blocking state, after triode Q2 conducting, the collection emitter-base bandgap grading conducting voltage 0.3V of triode Q2 is now triode Q1 emitter junction voltage, so triode Q1 all the time can not be in conducting operating state, light-emitting diode in optocoupler U2 does not have electric current to pass through all the time, now the phototriode in optocoupler U2 is not worked, emitter junction in triode Q3 is without conducting voltage, so low-tension current at once from resistance R 9 to resistance R 11 again to relay K 3 coils finally to ground.Now relay K 3 adhesives, become normally off normal battle originally, power taking in the L being narrated from the above, operating part after power taking is after the phase shortage judgement of open phase relay group K1 and K2, normal battle become the normally closed relay K 3 that arrives again, through the normally closed o'clock normally closed point to the first reset button 19 and the second reset button 20 of relay K 3, again to the normally closed point of the first limit switch 10, after series capacitance, arrive operation winding L 2 upper ends of single-phase actuating motor 5, more leading than starting winding L 1 voltage owing to now moving winding L 2, so now single-phase actuating motor 5 is driving driving wheel 7 to rotate counterclockwise, drive the first mechanical arm 8 to move downwards by trundle H1, due to the positioning action of alignment pin Z1, the other end of the first mechanical arm 8 upwards moves, drive the handle 13 of the first circuit breaker 1 to move to 0N position simultaneously.When the raised points T of driving wheel 7 arrives the position of the first limit switch 10, withstand the button of the first limit switch 10, the normally-closed contact of the first limit switch 10 disconnects, after the power supply of single-phase actuating motor 5 is cut off, stop operating, now the handle 13 of the first circuit breaker 1 is in 0N position, the first circuit breaker 1 closure, the first relay indicating light 15 is lighted, 14, the handle of the second circuit breaker 2 is so in OFF position, and the second circuit breaker 2 disconnects, so far this device work.According to the annexation of lead-out terminal 1D, the 1E of the first circuit breaker 1,1F and total output R, S, T, even if when input power is inputted by wrong A, C, B phase sequence, after this device correction, the therefore phase sequence of total output or correct R, S, T phase sequence.

2. while occurring that phase sequence changes when input power is sent a telegram here after having a power failure again in this device course of work, the course of action of this device phase order:

In the time that input power in this device course of work is pressed A, B, the input of C phase sequence, suppose that A, B, C, phase sequence are correct phase sequence, the first circuit breaker 1 is in off-state, the second circuit breaker 2 is in closure state, if now have a power failure suddenly, while again incoming call, input power phase sequence does not change, this device phase sequence switching actuator is failure to actuate, and the first circuit breaker 1 is still in off-state, and the second circuit breaker 2 is still in closure state.If input power phase sequence changes by A, C, B or other any A that is different from, B, when the input of C phase sequence, from the operating part L power taking through open phase relay group K1 and K2 phase shortage judgement after, normal battle become the normally closed relay K 3 that arrives again, through the normally closed o'clock normally closed point to the first reset button 19 and the second reset button 20 of relay K 3, again to the normally closed point of the first limit switch 10, after series capacitance, arrive operation winding L 2 upper ends of single-phase actuating motor 5, more leading than starting winding L 1 voltage owing to now moving winding L 2, so now single-phase actuating motor 5 starts to rotate counterclockwise, driving wheel 7 drives the second mechanical arm 9 upwards to move by trundle H2, due to the positioning action of alignment pin Z2, the other end of the second mechanical arm 9 moves downwards, drive the handle 14 of the second circuit breaker 2 to move to 0FF position simultaneously.When the raised points T of driving wheel 7 forwards the position of reversing switch 12 to, the handle 14 of the second circuit breaker 2 is got back to 0FF position completely, and the second circuit breaker 2 disconnects.Now the first circuit breaker 1 is also in OFF position, driving wheel 7 continues to rotate counterclockwise, and drives the first mechanical arm 8 to move downwards, due to the positioning action of alignment pin Z1 by trundle H1, the other end of the first mechanical arm 8 upwards moves, and drives the handle 13 of the first circuit breaker 1 to move to 0N position simultaneously.When the raised points T of driving wheel 7 arrives the position of the first limit switch 10, withstand the button of the first limit switch 10, the normally-closed contact of the first limit switch 10 disconnects, after being cut off, the power supply of single-phase actuating motor 5 stops operating, now the handle 13 of the first circuit breaker 1 is in 0N position, the first circuit breaker 1 closure, the first relay indicating light 15 is lighted, and so far phase sequence trimming process completes.According to the annexation of lead-out terminal 1D, the 1E of the first circuit breaker 1,1F and total output R, S, T, even if when input power is inputted by wrong A, C, B phase sequence, after this device correction, the therefore phase sequence of total output or correct R, S, T phase sequence.

When input power in this device course of work any while being different from A, B, the input of C phase sequence by wrong A, C, B or other, the first circuit breaker 1 is in closure state, the second circuit breaker 2 is in off-state, if now have a power failure suddenly, while again incoming call, input power phase sequence does not change, and this device phase sequence switching actuator is failure to actuate.The first circuit breaker 1 is still in closure state, and the second circuit breaker 2 is still in off-state.If input power phase sequence changes suddenly, according to correct A, B, when the input of C phase sequence, from L power taking, the normally closed some K1 of relay group judging through phase shortage and K2 are after the normally closed point of the first reset button 19, again to normally closed point and the normally closed point of limit switch 11 of the second reset button 20, by arriving startup winding L 1 end of single-phase actuating motor 5 after capacitor C, now because the startup winding L 1 of single-phase actuating motor 5 is more leading than the power supply of operation winding L 2, so now single-phase actuating motor 5 starts to clockwise rotate, driving wheel 7 drives the first mechanical arm 8 upwards to move by trundle H1, due to the positioning action of alignment pin Z1, the other end of the first mechanical arm 8 moves downwards, drive the handle 13 of the first circuit breaker 1 to move to 0FF position simultaneously.When the raised points T of driving wheel 7 forwards the position of reversing switch 12 to, the handle 13 of the first circuit breaker 1 is got back to 0FF position completely, and the first circuit breaker 1 disconnects.Now the second circuit breaker 2 is also in OFF position, driving wheel 7 continues to clockwise rotate, and drives the second mechanical arm 9 to move downwards, due to the positioning action of alignment pin Z2 by trundle H2, the other end of the second mechanical arm 9 upwards moves, and drives the handle 14 of the second circuit breaker 2 to move to 0N position simultaneously.When the raised points T of driving wheel 7 arrives the position of the second limit switch 11, withstand the button of the second limit switch 11, the normally-closed contact of the second limit switch 11 disconnects, after being cut off, the power supply of single-phase actuating motor 5 stops operating, the handle 14 of the second circuit breaker 2 is in 0N position, the second circuit breaker 2 closures, the second relay indicating light 16 is lighted, and so far phase sequence trimming process completes.According to the annexation of lead-out terminal 2D, the 2E of the second circuit breaker 2,2F and total output R, S, T, when input power is correct A, B, the input of C phase sequence, the phase sequence of output or correct R, S, T phase sequence.

3. in this device course of work, there is under-voltage, phase shortage, the course of action of this device that resets when the faults such as output overcurrent:

When this device first circuit breaker 1 is in off-state, the second circuit breaker 2 is in closure state, if input power is to input by correct A, B, C phase sequence, there is under-voltage, phase shortage in total input power now, the faults such as output overcurrent, the second circuit breaker 2 can be threaded off at once, and the second relay indicating light 16 extinguishes.And what switch after the L power taking of actuator operating circuit part process first due to phase sequence is the normal battle that phase shortage judges relay, and the now power supply of single-phase actuating motor 5 is cut off in halted state.As long as phase shortage judges that the K1 of relay group and the normally closed point of K2 exist phase shortage phenomenon simultaneously, from L to relay K 1 and the normally closed point of relay K 2 after, after diode D11 rectification, after resistance R 13 step-downs, arrive phase shortage indicator light 17 again, now indicator light 17 is lit, now this device non-transformer output.If under the condition of overcurrent, dropout, now due to the dropout feedback point NO closure of the second circuit breaker 2 of threading off, by L through closed NO now, after diode D14 dead resistance R16 step-down current limliting, arrive audible-visual annunciator 18, now trouble light 18 is lighted, and the prompting of sounding, if now input power phase sequence changes, while pressing the phase sequence input phase sequence switching actuator of A, C, B mistake, this device disconnects second circuit breaker 2 of threading off by commutation function, closed the first circuit breaker 1, realization automatically resets; If now input power phase sequence does not change, the necessary hand-reset of this device, before reset, because nearly all mold cased circuit breaker, after dropout, if will carry out closure next time, must first once disconnect and moving, just can carry out closure.After pending fault is got rid of, a pair of normal battle of pressing the second reset button 20, the second reset button 20 is closed, and a pair of normally closed point disconnects, and the loop in block system relay K4 and relay K 3, does not power with single-phase actuating motor 5.Then the relay group K1 and the K2 that judge through phase shortage, in the normal rear end power taking of making war of relay K 2, after the normally closed point of reversing switch 12, arrive the operation winding L 2 of single-phase actuating motor 5, because the operation winding L 2 of single-phase actuating motor 5 is now more leading than the power supply that starts winding L 1, so now single-phase actuating motor 5 starts to rotate counterclockwise, driving wheel 7 drives the second mechanical arm 9 upwards to move by trundle H2, due to the positioning action of alignment pin Z2, the other end of the second mechanical arm 9 moves downwards, drives the handle 14 of the second circuit breaker 2 to move to 0FF position simultaneously.When the raised points T of driving wheel 7 forwards the position of reversing switch 12 to, withstand the button of reversing switch 12, normally closed some Y1, Y2 of reversing switch 12 disconnect, after being cut off, the power supply of single-phase actuating motor 5 stops operating, the handle 14 of the second circuit breaker 2 is got back to 0FF position completely, and the second circuit breaker 2 completes reset.Now the first circuit breaker 1, the second circuit breaker 2 are all in off-state.Because the dropout feedback point NO on the first circuit breaker 2 reverts to again normal battle, the power supply of audible-visual annunciator 18 is disconnected, now quit work, and, do not sending the sound and light signal of warning.
