DC220V；
When there is breaker mechanism unbalanced three-phase lines situation, it is normally closed that unbalanced three-phase lines circuit first passes around breaker mechanism
Whether power supply conducting is as follows after the non-synchronous situation of necessary being three-phase for auxiliary magnet logic judgment：
Positive supply-＞ LP3-＞ DLA/DLB/DLC (three pairs of point parallel connections)-＞ LP1- ＞ 47TX1-＞ DLA/DLB/DLC-＞ Y2A
/ Y2B/Y2C-＞ negative supplies；
And at this time because following circuits are switched on：
Positive supply-＞ DLA/DLB/DLC (three pairs of normally closed points are in parallel)-＞ DLA/DLB/DLC (three pairs of opened point parallel connections)-＞
47T1- ＞ DLA/DLB/DLC-＞ negative supplies；
Cause 47T1 obtain it is electric after relay 47TX1 opened points 43.44 turn on, signal guard relay KL1 is obtained electric at this time, so
KL1 opened points 13.14 close afterwards, so that it is as follows to start signal self-holding circuit：
Positive supply-＞ LP1- ＞ SB1 (normally closed point)-＞ KL1（13.14 contacts）-〉KL1（A1.A2 contacts）- ＞ negative supplies；
Signaled at this time from signal guard relay KL1 toward backstage, and this signal is kept for a long time；If trouble shooting
Afterwards, operable signal return button SB1 at this time;Above-mentioned self-holding circuit is disconnected by SB1 buttons, three-phase is non-synchronous to keep signal to disappear
Lose；
The non-synchronous signal self-holding circuit of three-phase, and can hand-reset；This circuit personnel's discovering device failure convenient to overhaul,
Timely Maintenance and Repair, after maintenance, hand resetting, if the normal involution of energy, illustrates that trouble point releases, if after involution, after
Supervention signal, illustrates that trouble point does not release, and patrol officer can continue to investigate；The non-synchronous trip protection of three-phase is found before solving
Afterwards, patrol officer's investigation trouble point is imperfect, and the generation of trip protection phenomenon again, reduces number of equipment action after combined floodgate,
Extend equipment life；Original optimization front case, unbalanced three-phase lines signal is transient state form, after breaker protection separating brake action,
Unbalanced three-phase lines signal automatically terminates, and is unfavorable for patrol officer and subsequently overhauls investigation failure；Trip out in three phases un identical protection
The normally closed auxiliary contact of breaker is concatenated between mouth contact and positive electricity resource loop.This scheme avoids relay 47TX1,47TX2
Acted because of vibrations or other improper factors, cause the generation of breaker normal condition trip phenomenon；It turn avoid intelligent end
Position supervisory relay is divided to cause mistake because of vibrations or other improper factor actions in relay 47TX1,47TX2 in the component of end
The situation of monitoring produces by mistake；Original optimization front case is monitored without unbalanced three-phase lines auxiliary switch for circuit breaker position, is be easy to cause
Cause the monitoring of conjunction position incorrect because 47TX relay misoperations make, there is parasitic loop generation；This scheme is implemented to make to use equipotential
Parasitic loop is not present when testing three phases un identical protection, and effective verification is per the action of phase three phases un identical protection split-phase and phase
OFF signal is correct, in the case of breaker closing, the breaker when simulating the single time relay or exit relay and exporting by mistake
Not false tripping.
