Description of drawings:
Fig. 1 is schematic circuit diagram of the present invention.
The specific embodiment:
One circuit is formed
1. trunk electrical source of power branch road:
During 1. by electric set electric supply, by changeover module B1 powering load, changeover module B1 is made up of circuit breaker 5QF and motor drive mechanism MT1, the secondary contact SD1 (in this explanation: the device that all changeover modules comprise all in the frame of broken lines of accompanying drawing 1, and represent) that wherein also comprises 5QF by letter and number.Disconnect closure during separating brake during the same and lock of the state of secondary contact SD1 and 5QF.
During 2. by mains-supplied, comprise changeover module B2, B3.Changeover module B2 is by circuit breaker 6QF and secondary contact SD2 and secondary contact SD3, and motor drive mechanism MT2 forms.Changeover module B3 by circuit breaker 7QF with and secondary contact SD4 and secondary contact SD5 and motor drive mechanism MT3 form.
2. control circuit:
During 1. by electric set electric supply, comprise relay 3KT delayed contact 387, relay 7KX normally closed contact 7KX-1, normally closed contact 7KX-2, position select switch 2SA, normally closed point of relay 19KX and relay 18KX line bag, B3 secondary contact SD5 in secondary contact SD1 in time relay 1KT and delayed contact thereof and the B2 changeover module and the changeover module.
During 2. by mains-supplied, comprise relay 3KT delayed contact 375, relay 7KX normally closed contact 7KX-1 and normally closed contact 7KX-2, position select switch 2SA, the normally closed point 369 of relay 18KX, relay 19KX line bag, time relay 2KT.Secondary contact SD1 among the changeover module B1, the normal battle of relay 1RM and 2RM.Arbitrary connection of 1RM and 2RM is determined according to the phase sequence detection branch.The phase sequence detection branch is again by phase sequence relay 1RM4T and phase sequence relay 2RM4T, the relay 19KX 19KX-2 relay 2RM of often making war, and normally closed point 359, the normally closed point 356 of relay 1RM, the control line bag of normally closed point 359 and relay 1RM, 2RM is formed
Two, principle of work
Determine by position select switch 2SA during native system work, be to use electric set electric supply or mains-supplied.When position select switch 2SA is in the left side is mains-supplied.When being in the right is electric set electric supply.Know all power supply modes that resets when mediating, just all power supply circuit breakers are in gate-dividing state under motor drive mechanism drives.
1 resets
Native system resets and is divided into dual mode, the one, system power-on reset, relay 3KX delayed contact 375 deferred actions are just held the A4 of motor drive mechanism MT3 among the A4 end of motor drive mechanism MT1 among the changeover module B1 and the changeover module B3, supplying with a pulse, is all breaker open operations.(drive end of relay 3KT, 7KX is provided with and marks at this moment, in being in the control branch road of load) annotates: native system and load branch all have extra 24V DC supply, use for control.Two manually reset.Even a position select switch mediates, direct supply arrives a position select switch 2SA by the normally closed point of relay 3KT, by normally closed some 7KX-2 reach motor drive mechanism MT1, MT2, MT3 makes each breaker open operation.A wherein normally closed 7KX-1,7KX-2 are the normally closed points of the relay of a/c system, and during a/c system work, 7KX-1,7KX-2 disconnect, and at this moment, it is therefore invalid that hand reset and other switch.Can only could select once more after the a/c system shutdown.
The logical position of powering mode select switch switches to another kind of powering mode by a kind of powering mode.Switch again after must resetting earlier, could be effectively.
2 when a position select switch SA is in the right, the normally closed point of DC control supply passage period relay 3KT drive end and the coils from parallel connection of coils end of normally closed some 19KX-1 of select switch relay 19KX to relay 1KT that put in place to relay 7KX normally closed contact 7KX-1 to 2SA.(relay 18KX action makes city's power mode invalid this moment, reaches the purpose of interlocking.)
Relay 1KT deferred action is connected its normal 371 time-delays of making war, and DC current arrives normally closed some SD2 by it and holds (being its combined floodgate control end) to the A2 that normally closed some SD5 reaches motor drive mechanism MT1 again.Make motor drive mechanism work, by mechanical force the operating handle of circuit breaker is moved, make the generator set power supply reach load by circuit breaker 5QF, promptly this moment, electric set electric supply was effective.
3. when the position select switch is in the left side, when being city's power mode, the normally closed point relay 7KX of DC control supply passage period relay 3KT arrives normally closed some 7KX-1 to the drive end parallel connected end of normally closed some 18KX of relay 18KX up to relay 19KX line bag and time relay 2KT.Relay 19KX action this moment, its normally closed some 19KX-1 disconnects (make this moment generator set pattern invalid), while time relay 2KT delay working, its normal 376 time-delays of making war are connected, again to normally closed some SD1 arrive relay 1RM and relay 2RM normal battle one end relay 1RM and relay 2RM determine by phase-detection whether it connects, or which is connected).Connect if often open 387, arrive the combined floodgate end A2 of motor drive mechanism MT3, make motor drive mechanism work, the handle action of relay 7QF is closed a floodgate by mechanical force.Power supply arrives load by circuit breaker 7QF.If normal 382 connections of making war of relay 2RM, working pulse arrives the combined floodgate point A2 of MT2 so, and 6QF is closed a floodgate, and reaches load from power supply.Above motor drive mechanism (closing a floodgate and separating brake) all is that the pulse by certain width reaches close a floodgate end A2 or separating brake end A4 motor drive mechanism is closed a floodgate or separating brake.
Because being logical phase sequences, the connection of relay normally open point 382 and 387 detects decision.Detect (its repeat circuit 19KX often make war 19KX-2 close a floodgate at this moment) so narrate phase sequence now again.
When the detected phase sequence of 1RM4T is correct, direct supply by 19KX-2 arrive 1RM4T by the contact of connecting to normally closed point 356 to normally closed some SD4 to relay line bag 2RM (normally closed point 359 is moved, makes the cut-out of another phase sequence detection 2RM4T branch road).Normal 382 actions of making war are closed a floodgate, and make corresponding switching effective.
When 2RM4T detects correct phase sequence, direct supply by relay normally open point 19KX-2 to 2RM4T to normally closed point 359 to normally closed some SD3 to relay 1RM line bag.Promptly normal 378 actions of making war are closed a floodgate, and make corresponding switching effective.
