4) behind the circuit breaker manual brake separating, break off 1 pin of relay and the AC power on 3 pin, 1 pin and 4 pin by external loop, intermediary element J4 and J5 are returned, with the locking of reclosing function.
5) test button and connecing is arranged on the normal opened contact J4-2; Throwing is moved back relay in running status when a reclosing distant place; Press test button, intermediary element 1ZJ can move once, and relay inside also can be moved and sent the order of closing a floodgate; But circuit breaker can not overlap at coincidence status again, and the locking lamp of face onboard led is bright.
A kind of application example of multiple switching relay according to the invention is following:
Behind the circuit breaker closing by hand, obtain AC power at 1 pin, 4 pin of relay, thereby be 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 button switches in remote location, and then the inner normal opened contact J6-1 of relay returns, and combined floodgate outlet contact 7 pin of relay, 9 pin are by normal opened contact J3-1 control in the relay.When reclosing is dropped in a scheduling distant place, the intermediary element J1 in the relay 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 7 pin of relay, 9 pin possess the action exit condition, and promptly the reclosing function drops into.When reclosing is withdrawed from a scheduling distant place, the intermediary element J2 in the relay will receive the positive supply pulse that external loop is sent here, and through the internal actions of relay, J3-1 will return; Combined floodgate outlet contact 7 pin of relay, 9 pin do not possess the action exit condition, and promptly the reclosing function withdraws from.
If on the spot/and distant place selector button switches in remote location, and then the normal opened contact J6-1 in the relay is closed; Then the combined floodgate of relay outlet contact 7 pin, 9 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 1 pin, 3 pin of relay pay contact and get AC power through circuit breaker, sending the order of closing a floodgate after the relay internal actions; Promptly closing a floodgate exports contact 7 pin and the connection of 9 pin, makes breaker closing.If breaker closing trips in permanent fault once more, 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 once more.
Behind the circuit breaker manual brake separating, 1 pin of relay and 3 pin all lose AC power on 1 pin and 4 pin, and intermediary element J4 and J5 return, the locking of reclosing function.
Therefore; Relay according to the invention has solved a line protection reclosing function distant place in the former conventional substation can not remote control throw the problem of moving back; Under the situation that does not change original M3-A 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.
