Behind the circuit breaker closing by hand, 8 pin of relay get positive supply, thereby are the capacitor C charging in the relay through above-mentioned a series of internal actions.Charging is in and treats coincidence status after accomplishing.
If on the spot/and distant place selector switch is chosen in remote location, and then the inner normal opened contact J5-1 of relay returns, and combined floodgate outlet contact 4 pin-1 pin of relay is by normal opened contact J3-1 control in the relay.When the scheduling remote control drops into reclosing, relay bosom element J1 will receive the positive supply pulse that external loop is sent here, and through the internal actions of relay, J3-1 is with closure.Combined floodgate outlet contact 4 pin-1 pin of relay possesses the action exit condition, and promptly the reclosing function drops into.When reclosing is withdrawed from the scheduling remote control, the inner J2 intermediary element of relay will be received the positive supply pulse that external loop is sent here, and through the internal actions of relay, normal opened contact J3-1 will return.Combined floodgate outlet contact 4 pin of relay, 1 pin do not possess the action exit condition, and promptly the reclosing function withdraws from.
If on the spot/and distant place selector switch is chosen in regard to destination location, and then the inner normal opened contact J5-1 of relay is closed.Then the combined floodgate of relay outlet contact 4 pin, 1 pin possess the action exit condition, and promptly the reclosing function drops into.
After the breaker protection tripping operation; If relay reclosing function input and be in and treat coincidence status, make 7 pin of relay pay contact and get negative supply through circuit breaker, send closing pulse after the relay internal actions; Promptly closing a floodgate exports contact 4 pin and the connection of 1 pin, makes breaker closing.If breaker closing trips in permanent fault once more, because capacitor C has little time to be charged to the operation voltage of intermediary element ZJ, close a floodgate outlet contact 4 pin and 1 pin can not connected once more.
Behind the circuit breaker manual brake separating, 6 pin of relay will get negative supply, and capacitor C is through resistance R 6 discharges, the locking of reclosing function.
Therefore; Relay according to the invention has solved line protection reclosing function in the former conventional substation can not remote control throw the problem of moving back; Under the situation that does not change original DH-1 multiple switching relay performance and installation dimension; Utilize the principle and the technology of the static multiple switching relay of original maturation, installed additional remote control throw move back function, on the spot/distant place selector switch, improved the level of product.
Relay inside has adopted the magnetic cylinder to keep little auxiliary relay, does not receive the influence of accessory power supply fault outage.After relay accessory power supply dead electricity, the state on the spot of relay and a distant place are thrown the state that moves back and are all remained unchanged.After relay re-powered, the reclosing function can not withdraw from from dropping into the position mistake, also not can from withdraw from the position miscarry into.
The present invention realizes the three-phase single shot reclosing and dispatches the remote control throwing and move back the reclosing function on transmission line.It can match with relaying protection, and the circuit breaker that is disconnected is closed a floodgate automatically again, is temporary like fault, then system restoration operation; Like fault is permanent, tripping operation once more after then overlapping, and no longer overlap; And scheduling can require distant place control reclosing function according to operational mode, thereby saves workload.
