Below coordinate referring to shown in Fig. 1, Fig. 2, concrete wiring relation and the working method of this relay is described.Fig. 1 is the theory diagram of relay of the present invention, and Fig. 2 is the cut-away drawing of relay of the present invention.
5 pin of described relay meet external loop positive supply+KM, and 11 pin meet external loop negative supply-KM; By DC/DC transducer, carry out DC110V to the current conversion of DC24V; The maintenance electric current of this relay is between 0.25A ~ 2A, and reference time delay is between 0.05S ~ 9.95S.
1, a distant place is thrown and is moved back function
A be provided with on the spot/distant place of described relay selector switch, it controls normal opened contact K-1 and the normally closed contact K-2 being connected with DC/DC transducer 24V outgoing position.
When on the spot described/distant place selector switch is chosen in remote location, normally closed contact K-2 is closed, and the two-position relay J6 being connected with described contact K-1, K-2 returns, and controls its normally closed contact J6-2, J6-3 closed.
1) when 13 pin of relay, receive and dispatch while sending the order of reclosing input from a distant place by instruction, the intermediary element J1 action being connected with normally closed contact J6-2, controls the normal opened contact J1-1 closure being connected with DC/DC transducer.
Now, the two-position relay J3 adhesive (pulse duration 100MS) being connected with normal opened contact J1-1, its normal opened contact J3-1 is closed, reaches the order ground that reclosing is dropped in a distant place, and the realization of reclosing function below can specifically describe.After reclosing drops into, because normal opened contact J3-4 is also closed, on relay panel, there is LED to drop into indicator light luminous; Due to normal opened contact J3-2, normally closed contact J3-3 action, at reclosing remote input signal contact 15-16 pin, 17-18 pin, there is signal output in addition.
2), when 14 pin of relay, when receiving the reclosing sending by instruction from a distant place in control room and exiting command, the intermediary element J2 action being connected with normally closed contact J6-3, controls the normal opened contact J2-1 closure being connected with DC/DC transducer.
Now, the two-position relay J3 being connected with normal opened contact J2-1 returns to (pulse duration 100MS), and normal opened contact J3-1 opens, and reaches the order ground that reclosing is exited in a distant place.After reclosing exits, due to normal opened contact, J3-4 also disconnects, and the LED on relay panel drops into indicator light and extinguishes; Because normal opened contact J3-2, normally closed contact J3-3 return, the signal that drops into signal contact 15-16 pin, 17-18 pin in reclosing remote control returns in addition.
2, on the spot push button function is selected in/distant place
1) as described in above-mentioned, when on the spot/distant place selector switch is selected remote location, normally closed contact K-2 is closed, and two-position relay J6 returns, and normally closed contact J6-2, J6-3 are closed, and scheduling can be thrown and move back reclosing from a distant place.Simultaneously normally closed contact J6-6 is also closed, makes on panel viridescent LED distant place indicator light luminous, and now normal opened contact J6-4 disconnects, and signal contact 19～20 pin are not communicated with on the spot.
2) when on the spot/distant place selector switch is selected extremely with regard to position, normal opened contact K-1 is closed, two-position relay J6 action, make its normal opened contact J6-1 closed, normally closed contact J6-2, J6-3 open, intermediary element J1, J2 dead electricity, and two-position relay J3 keeps an original distant place to throw the state that moves back.Now, control room can not change the throwing of reclosing device again and move back state from a distant place, and state is moved back in the throwing that can only take local operation to change reclosing device.Because normal opened contact J6-5 is closed, indicator light is luminous on the spot to make there is red LED on panel, drops into indicator light simultaneously and is also connected luminous with the described normal opened contact J5-5 of closure by diode D1.Normal opened contact J6-4 is closed, and signal contact 19～20 pin are connected on the spot.
3, reclosing function
Relay of the present invention has adopted the principle of novel static multiple switching relay, identical with the multiple switching relay function of existing M3-A in function, inside has anti-bouncing function, the digital time delay reclosing time of adjusting, very convenient, intuitive and reliable.
1) concrete, after outside circuit breaker closing by hand, relay 1 pin, 4 pin obtain AC power, make to be serially connected in the intermediary element J5 action between bipod, make the normal opened contact J5-1 being connected with 5 pin closed, and then make the capacitor C that is connected with this normal opened contact J5-1 by resistance R 4, can be communicated with and charge with external loop positive-negative power ± KM; Now, reclosing drops into, make by after series diode D3 and connect that to be arranged on the upper red LED AC power lamp of described intermediary element J5 bright, and make the green DC power supply lamp that is connected with the described normal opened contact J5-1 of closure bright, the red locking lamp that also makes to be attempted by resistance R 4 is bright; After 15～25 seconds, locking lamp extinguishes, and represents that charging completes, enters and treats coincidence status.
2) after described breaker protection tripping operation, when on the spot/distant place selector switch is chosen in regard to position (normal opened contact J6-1 is closed), or when on the spot/distant place selector switch is chosen in remote location and reclosing is dropped in a distant place simultaneously (normal opened contact J3-1 is closed), 1 pin of relay will be made by circuit breaker auxiliary contact, 3 pin obtain AC power, make to be serially connected in the intermediary element J4 action (described intermediary element J5 returns simultaneously) between bipod, control normal opened contact J4-1, J4-2 is closed, make by this normal opened contact J4-1, J4-2 is serially connected in 5, on 11 pin and the time component SJ being communicated with positive-negative power ± KM action.
After time delay certain hour, control relay sends the closing pulse of 100MS, and capacitor C is discharged to the voltage winding of intermediary element 1ZJ by closed time component contact SJ-1, the voltage winding of intermediary element 1ZJ, the action of electric current winding; Make the normal opened contact 1ZJ-1 being connected in series with the electric current winding of described intermediary element 1ZJ closed, and by closed J6-1 or J3-1(and closed normally closed contact 2ZJ-1, below describe in detail), will be communicated with 9 pin with relay 7 pin, send the order of closing a floodgate and make breaker closing.
Sending while closing a floodgate order, due to also, by after series diode D2 and connect that to be arranged on described intermediary element J4 upper, described LED AC power lamp was also sent out bright; Simultaneously the above red locking lamp of panel is bright, and the red action lamp being attempted by the voltage winding of time component SJ is bright, and after breaker closing, described action lamp goes out, and locking lamp extinguishes after charging in 15～25 seconds.
If what occur on circuit is temporary fault,, after breaker closing success, can again for capacitor C, charge, make described relay again in treating coincidence status.If after breaker closing, the tripping operation again due to permanent fault, now capacitor C has little time to be charged to intermediary element ZJ action required voltage, thus intermediary element 1ZJ akinesia, thus guarantee only to carry out single shot reclosing.
3) an anti-jump intermediary element 2ZJ, its voltage winding and normal opened contact 2ZJ-2 serial connection are arranged between described relay 2 pin, 11 pin.
The electric current winding of this anti-jump intermediary element 2ZJ is arranged between 10 pin, 12 pin of relay, to be serially connected in external loop brake division loop of circuit breaker, moves during circuit breaker separating brake outside.(external loop herein connecting is not shown)
When external loop breaker open operation, the action of the electric current winding of this anti-jump intermediary element 2ZJ, normal opened contact 2ZJ-2 is closed.When relay 2 pin have lasting positive supply, or when relay 7 pin are communicated to the electric current winding of described intermediary element 1ZJ, the voltage winding of anti-jump intermediary element 2ZJ moves and keeps normal opened contact 2ZJ-2 closed, thereby normally closed contact 2ZJ-1 is returned, relay 2 pin and 7 pin all can not be communicated with 9 pin, external loop circuit breaker cannot close a floodgate, and stops external loop circuit breaker to continue to jump between separating brake and "on" position.
4) after circuit breaker manual brake separating, by external loop, disconnect 1 pin of relay and the AC power on 3 pin, 1 pin and 4 pin, intermediary element J4 and J5 are returned, by the locking of reclosing function.
5) test button connecing is arranged on normal opened contact J4-2, when reclosing remote putting on/off relay is in running status, press test button, intermediary element 1ZJ can move once, relay inside also can be moved and be sent the order of closing a floodgate, but circuit breaker can not overlap at coincidence status again, the locking lamp of face onboard led is bright.
A kind of application example of multiple switching relay of the present invention is as follows:
After circuit breaker closing by hand, at 1 pin, 4 pin of relay, obtain AC power, thereby be that capacitor C in relay is charged by above-mentioned a series of internal actions.After having charged, in treating coincidence status.
If on the spot/distant place selects button to switch in remote location, the inner normal opened contact J6-1 of relay returns, and combined floodgate outlet contact 7 pin of relay, 9 pin are controlled by normal opened contact J3-1 in relay.When reclosing is dropped in a scheduling distant place, the intermediary element J1 in relay is by the positive supply pulse of receiving that external loop is sent here, and by the internal actions of relay, J3-1 is by closure; Combined floodgate outlet contact 7 pin of relay, 9 pin possess action exit condition, and reclosing function drops into.When reclosing is exited in a scheduling distant place, the intermediary element J2 in relay is by the positive supply pulse of receiving that external loop is sent here, and by the internal actions of relay, J3-1 will return; Combined floodgate outlet contact 7 pin of relay, 9 pin do not possess action exit condition, and reclosing function exits.
If on the spot/distant place selects button to switch in remote location, the normal opened contact J6-1 in relay is closed; The combined floodgate of relay outlet contact 7 pin, 9 pin possess action exit condition, and reclosing function drops into.
After breaker protection tripping operation; if relay reclosing function drops into and in treating coincidence status, make 1 pin of relay, 3 pin obtain AC power by circuit breaker auxiliary contact, after relay internal actions, send the order of closing a floodgate; close a floodgate and export contact 7 pin and the connection of 9 pin, make breaker closing.If breaker closing trips again in permanent fault, because capacitor C has little time to be charged to intermediary element 1ZJ action required voltage, close a floodgate outlet contact 7 pin and 9 pin can not connected again.
After circuit breaker manual brake separating, 1 pin of relay and 3 pin, equal lose AC power on 1 pin and 4 pin, intermediary element J4 and J5 return, the locking of reclosing function.
Therefore; relay of the present invention has solved a line protection reclosing function distant place in former conventional substation can not remote control throw the problem of moving back; in the situation that not changing original M3-A multiple switching relay performance and installation dimension; utilize principle and the technique of original ripe static multiple switching relay; install remote control throwing additional and moved back function, on the spot/distant place selector switch, improved the level of product.
Relay inside has adopted magnetic cylinder to keep little auxiliary relay, is not subject to the impact of accessory power supply fault outage.After relay accessory power supply dead electricity, a distant place for relay on the spot state and a distant place is thrown the state that moves back and is all remained unchanged.After relay re-powers, reclosing function can not exit from dropping into position by mistake, also not can from exit position miscarry into.
The present invention on transmission line, realizes three-phase single shot reclosing and reclosing function is moved back in dispatching remote control throwing.It can match with relaying protection, and the circuit breaker being disconnected is closed a floodgate automatically again, and if fault is temporary, system is resumed operation; If fault is permanent, tripping operation again after overlapping, and no longer overlap; And scheduling can require a distant place to control reclosing function according to operational mode, thereby saves workload.
