When there is the inconsistent situation of breaker mechanism three-phase, the inconsistent loop of three-phase first after the normally closed auxiliary magnet logic of breaker mechanism judges whether the necessary being three-phase non-same period of situation power turn-on as follows:
Positive supply-> LP3-> DLA/DLB/DLC (parallel connection of three pairs of points)-> LP1-> 47TX1-> DLA/DLB/DLC-> Y2A/Y2B/Y2C-> negative supply;
And now because following loop is switched on
Positive supply-> DLA/DLB/DLC (three couples normally closed in parallel)-> DLA/DLB/DLC (three pairs of normal parallel connections of making war)-> 47T1-> DLA/DLB/DLC-> negative supply;
Cause 47T1 to obtain normal 43.44 conductings of making war of electric rear relay 47TX1, now signal latching relay KL1 obtain electric, normal 13.14 closures of making war of KL1 then, thus it is as follows to have started signal self-holding circuit:
Positive supply-> LP1-> SB1 (normally closed point)-> KL1(13.14 contact)-> KL1(A1.A2 contact)-> negative supply;
Now from signal latching relay KL1, toward backstage, signaled, and this signal is long-term maintenance; If after trouble shooting, now can operation signal involution button SB1; By SB1 button, disconnect above-mentioned self-holding circuit, the three-phase non-same period of inhibit signal disappears;
The three-phase non-same period of signal self-holding circuit, and can hand-reset; This loop facilitates maintainer's discovering device fault, in time Maintenance and Repair, and after maintenance, hand resetting, if can normal involution, illustrate that fault point removes, if after involution, continues to signal, and illustrates that fault point do not remove, patrol officer can continue to investigate; Before having solved, find that after the three-phase non-same period of trip protection, it is imperfect that patrol officer investigates fault point, after combined floodgate, the generation of trip protection phenomenon again, has reduced number of equipment action, has extended equipment life; Scheme before former optimization, the inconsistent signal of three-phase is transient state form, after the action of breaker protection separating brake, the inconsistent signal of three-phase automatically terminates, and is unfavorable for the follow-up maintenance investigation of patrol officer fault; Between three phases un identical protection tripping operation outlet contact and positive supply loop, be connected in series circuit breaker is normally closed auxiliarycontact.This scheme has avoided relay 47TX1,47TX2 because of vibrations or other improper factors move, cause the generation of circuit breaker normal condition trip phenomenon; Avoided again minute position supervisory relay in intelligent terminal assembly at relay 47TX1,47TX2 produces because of vibrations or the action of other the improper factors situation about monitoring that leads to errors; Before former optimization, scheme monitors without the inconsistent auxiliary switch for circuit breaker of three-phase position, easily causes because of 47TX relay misoperation and does to cause that co-bit supervision is incorrect, has parasitic loop to produce; While making to adopt equipotential test three phases un identical protection, there is not parasitic loop in this scheme implementation; and effectively verify that every phase three phases un identical protection phase-splitting action and coherent signal are correct; in breaker closing situation, circuit breaker false tripping not when the simulation single time relay or exit relay export by mistake.
